INTRODUCTION

1.1 Applicability

This manual has been produced for the purpose of both preparation and review of estimates for RTA projects. It is applicable to a wide range of RTA projects, delivery systems and complexity of estimates, from small maintenance projects undertaken by RTA’s own workforce to major infrastructure projects delivered by private funding and construction. The background and experience of personnel preparing or reviewing estimates for RTA is widely varied. The manual is intended to be a concise, hands-on, user friendly document which will provide the person responsible for preparation of the estimate with sufficient guidance to satisfactorily produce a reliable estimate. For the experienced estimator, the manual provides data and guidance on RTA specific estimating terminology, requirements and estimate presentation formats. While the manual is complimentary to other RTA publications and documents, it is intended to essentially stand alone, without the need to continually locate and refer to other documents. For this reason, relevant important information from other RTA documents has been reproduced in this manual. The manual contains requirements, and utilises terminology and features, specific to RTA. It is not intended for use on other than RTA projects.

The final out-turn dollar expenditure on a project.

Anticipated Final Cost

The sum of expenditure to date and the forecast expenditure, in outturn dollars, to complete the project.

Concept Estimate

An estimate in current dollars prepared during the concept development phase and finalised following the determination of the Environmental Impact Assessment and concept approval.

Contingency

Non-variation provision which covers circumstances that could not be forseen at the time of preparation of the estimate.

Current Dollars

The value of work expressed in dollars of the day by inflating actual past expenditures and deflating projected future expenditures according to the approved inflationary factors.

Definitive Estimate

OVERVIEW OF RTA REQUIREMENTS

CHAPTER0

2.1 Summary RTA’s current estimating policy is focused on the preparation of “unlikely to be exceeded” estimates. This means that the Actual Cost of a project has a 90% probability of not being greater than the estimate prepared at any project stage. An alternative way of expressing this, is that estimates are to have a 90% confidence factor of not being exceeded. At the same time, estimates must not be excessively conservative. Estimates must make reasonable allowances for risks and contingencies, and items which are likely to be included in the final project scope through processes such as environmental determinants and community consultation. Review of project estimates is mandatory. This chapter: • details general responsibilities, delegations and accountabilities within RTA; • contains a list of relevant Australian Standards and RTA documents; • details RTA’s project stages and the estimates associated with each stage; and • details presentation requirements for estimates.

A standard summary structure, which is to be used for all development project estimates, is contained in Appendix 2.1. For smaller maintenance, traffic or road safety projects a modified work breakdown structure may be adopted. At a level below this, the Project Manager RTA Project Estimating Edition 1, Revision 0

will decide whether the estimate should be formulated geographically or functionally, on a project by project basis. Proprietary software normally has the facility to present estimates in both of these ways, thereby simplifying the task of modifying estimates. Within RTA usage, the word “estimate” without “out-turn” means dollar values in the year of the estimate. A date must therefore be included in all estimates.

2.2 RTA Estimating Policy The definition of an estimate in Chapter 1 is a combination of the definition from RTA’s Project Management Guidelines and that contained in F.J.Slattery’s “Fundamentals of Estimating for Engineering Construction”. The contribution from Slattery is the stated recognition of constraints on the estimating process at various project stages and in particular the need to ensure that the targeted level of estimate accuracy is compatible with the available information. Although such a qualification ought to be self-evident, the estimating fundamental reflected, namely that of matching estimating effort and particularly expectation of outcome with available information, is not always observed. This should be borne in mind by all estimators when preparing estimates for RTA. The acceptable range for Strategic, Concept and Detailed Estimates, expressed as a percentage of Actual Cost, has previously been -30% to +30%, -20% to +20% and -10% to +10% respectively. These ranges reflect the fact that as a project is developed the scope and risks will become increasingly better defined. This is shown diagrammatically in Figure 2.1.

Figure 2.1 Traditional Approach to Estimating However, the impact of this philosophy is that in the case of 50% of estimates, the Actual Cost is higher than the estimate; and in the case of 50% of estimates, the Actual Cost is lower than the estimate. This philosophy is no longer appropriate for budgeting reasons. Current RTA policy, in response to changes in Client requirements, is that estimates are to be produced on an “unlikely to be exceeded” basis, and therefore there must be a high degree of confidence that the Actual Cost will be less than or equal to the estimated cost. This policy is equivalent to a lower range of estimate variation from Actual Cost of zero. This is shown diagrammatically in Figure 2.2.

Figure 2.2 Required RTA Approach Estimating in such an environment requires a conservative but realistic view of the project scope together with the risks and contingencies associated with the project, particularly in the early project stages where less detailed project information is available. The estimator may, in producing a “not to be exceeded” estimate, be tempted to take an inappropriately conservative view in the face of uncertainties. The challenge for the estimator is to arrive at a realistic (that is, not overly conservative) view of the project scope and risks and assign appropriate contingencies, in order to produce a meaningful estimate within the “not to be exceeded but not to be excessive” band of acceptability. All estimates must include a detailed consideration of RTA’s project costs, including project management. These costs must be estimated essentially on a first principles basis, taking into account the expected RTA personnel required for the project and appropriate charge out rates, inclusive of personnel direct costs and regional and corporate overheads.

Chapter 2



Estimates are relevant only to a particular project scope, or range of scopes, which must be clearly set out as part of the estimate. Estimates must make reasonable allowances for risks and contingencies. Estimates should also make provision for items that are considered likely to be ultimately required, having regard to such inputs as environmental determinants and community input on the final project scope. Such items should be included as specific allowances and not through an increase in contingency. Peer review of project estimates is mandatory and should be undertaken by an experienced officer independent of the project team. For projects over $20M in value ($10M for Federally funded projects) the estimate is to be submitted, after peer review, to the RTA Project Management Office (PMO) for review and concurrence.

2.3 Responsibilities and Approvals

This section contains general responsibilities and approvals related to estimating. More detailed descriptions, where appropriate, are contained within the relevant sections of this manual. RTA’s policy is to ensure that there are clear lines of responsibility and accountability to ensure that the best possible outcome is achieved. To assist in this process, this section assigns those responsibilities in regard to the preparation, review, concurrence, approval and acceptance of project estimates.

2.3.1 Estimate Preparation The Project Manager is responsible for: • establishing the Scope of Work in consultation with the Client’s Representative;



• • • 2-5 • • •

• preparation of strategic, concept and detailed estimates; • carrying out the tasks in the checklists for preparation of the various stages of estimates; • preparation of estimates for comparison with tenders; and • providing evidence of peer review (by a Senior Project Manager where applicable). The Client Representative is responsible for: • ensuring that the estimate is consistent with the scope of work and available funding.

2.3.2 Estimate Review and Concurrence To support RTA’s commitment to achieve accurate project estimates, PMO has been assigned the role of review and concurrence of some project estimates. Accordingly: For all estimates of cost greater than $20 million, all Federally funded project estimates of cost greater than $10 million, and for all high risk complex estimates of cost, the Estimator, PMO is responsible for: • checking that all necessary documentation has been completed and submitted by the Project Manger; • reviewing pareto item quantities and rates, eg earthworks, pavement, structures; • identifying potential errors in the estimate; • reviewing project constructability; • assessing construction methodologies; • verifying that known risks have been identified and appropriate allowances have been made in the estimate; • verifying that key assumptions have been listed and appropriate allowances have been made in the estimate; • verifying that previous quantities, rates, lump sums and contingencies have been reviewed as additional information becomes available; and • preparation of a report recommending concurrence to the estimate of cost.

• •

2 - 6 ••

Chapter 2



The General Manager, PMO is responsible for: • ensuring that all necessary documentation is in order; • ensuring that the estimate is reasonable for the scope of work; and • signing off concurrence.

2.3.3 Approvals For estimates of cost less than $5 million, the Section Manager is responsible for approval. For estimates of cost greater than $5 million and less than $50 million, the Branch Manager or the Regional Manager is responsible for approval. For estimates of cost greater than $50 million, the Director, Client Services is responsible for approval. The approving officer is also responsible for recommending and supporting the Project budget.

2.3.4 Estimate Acceptance The Client Representative is responsible for: • recommending the approval of the project budget based on a proposed funding profile.

The Client is responsible for acceptance of the estimate and approval of the project budget.

2.5 Project Stages The stages in an RTA project lifecycle at which an estimate is required are listed below. These stages are typical for medium to large development projects. It is expected that there would be lesser stages for smaller development, maintenance, traffic and road safety projects.

Estimate Stage

When Prepared

Strategic

As part of a route or area strategy and reported in the Route or Area Strategy Report.

Revised Strategic

On completion of desktop study work at commencement of the Option Investigation Phase and reported in the Project Development Proposal.

Preliminary

At the end of the “Option Investigation Phase” and included in the Preferred Option Report.

Initial Concept

After the development of an engineering concept on the preferred option. It is reported in the Initial Concept Design Report.

Concept

Prior to finalisation of the EIS or REF and reported in the Concept Design Report.

Revised Concept

During finalisation of the Representations Report and submitted together with this report.

Final Concept

After receipt of the Conditions of Approval and any design amendments. The estimate is reported in the Project Implementation Proposal.

Detailed

On completion of the detailed design and reported separately.

Completely new estimates, rather than review and modification of previous estimates, are to be prepared at least at Strategic, Initial Concept and Detailed stages to ensure that any changes and modifications to previous estimates are fully incorporated and that appropriate rigour is applied to the estimating process.

2.6 Presentation of Estimates A standard Summary structure for development project estimates is shown in Appendix 2.1. (This is identical to the structure contained in Table 3.1 of the Project Management Guidelines – Estimating, Scope and Cost Control for Development Projects.) This Summary sheet is to be used for all development project estimates. An electronic version of



• • • 2-9 • • •

this summary sheet can be accessed through PM21 (Project Management System) on the PMO web site. In preparation of the Summary, consideration must be given to the accuracy of the presented estimated cost. The Project Manager should select an appropriate level of rounding commensurate with the stage of the project and the accuracy of the estimate. For example, strategic estimates within the range $0 to $50 million could be rounded to the nearest $1 million to $2 million, and strategic estimates over $50 million rounded to the nearest $5 million to $10 million. Rounding should only be done once at the end of the estimate and not progressively within the estimate. At the level below that of the Summary, the estimator will develop a more detailed summary, the make-up and appearance of which will depend on the type of estimate and the estimating methodology adopted. Further guidance on appropriate styles is contained in Chapters 5, 6 and 7 of this manual. On major linear type projects, such as roads and tunnels, the estimator will be faced with the choice of presentation of the estimate either geographically or functionally. As an example, a road project may be presented either as costs for specific sections between selected chainages or as total costs for major elements such as earthworks, pavements and the like. Each type of presentation has advantages. A geographic presentation is required for comparison of subroutes within an overall route. Such a presentation has disadvantages, however, in value engineering exercises where a global change in an item over the whole project, such as pavement type, requires reworking in each geographic section rather than in one item for the whole project, as would be the case in the functional type presentation. The Project Manager will decide which style is likely to provide the most flexibility for the particular project.

A major advantage of the majority of proprietary estimating software is the facility to present estimates in two or more alternative ways. While obligatory use of proprietary software is not yet RTA policy, those undertaking repetitive estimates of major projects may find the benefits of such software worthwhile. Further details of proprietary software are contained in Chapter 10. Within RTA usage, the word “estimate” without “out-turn” means dollar values in the year of the estimate. All estimates must therefore include a date, however a month and year is sufficient.

ESTIMATING APPROACH

CHAPTER0

3.1 Summary RTA’s estimating approach is to require estimates be prepared at least at three stages of development of a project: • Strategic; • Concept; and • Detailed.

This chapter: • discusses various methods of preparation of estimates (global, unit rates, first principles); • requires that the scope of the project be properly and appropriately specified; • requires that certain items (including constructability and program) be considered in the preparation of an estimate; • considers special issues (including asset management, occupational health and safety, environment and traffic) to be considered in the preparation of a project estimate; • discusses consideration of risk and contingency in estimates; • considers the use of value management techniques; • considers the use of historical cost data; and • requires the implementation of Quality Assurance practices in the preparation and checking of estimates.

3.2 Types of Estimates The types of estimates undertaken by RTA for development projects are listed in Chapter 2. The main types, and the purposes for which these estimates are used, are as follows.

It may further be seen that the upper level accuracies required of RTA’s strategic, concept and detailed estimates are met or exceeded by accuracies achieved by the approximate (or order of magnitude), preliminary and detailed (or definitive) estimate. It may be concluded that similar methods should be used to prepare each of these corresponding estimate types. RTA’s recent experience has found this to be generally true of preliminary / concept estimates and detailed (or definitive) estimates. However, experience has been that strategic estimates based on the “approximate” or “order of magnitude” methodology do not deliver RTA’s requirements of a strategic estimate with sufficient certainty. This has been found to be the case particularly for road project estimates based simply on $ per km.

3.3 Methods of Estimating All estimates utilise the basic concept of division of a project into sufficiently small elements so as to allow a single rate or unit cost to be applied to each element, extending the quantities and rates to determine a cost for each element, summing the resulting elemental costs and finally applying additional costs to give a complete estimate. The basic difference in the estimate types is the degree to which a project is divided into elements and the method used to apply rates and the additional costs. The more rigorous the process used, the greater will be the certainty of estimate outcome or (in other words) the “accuracy” of the estimate. The method chosen for the preparation of an estimate depends on both the purpose for which the estimate is required (and therefore the required accuracy of the estimate) and the level of detail of available data. There is little point, for example, in commitment of the resources required to prepare a detailed first principles estimate on the basis of strategic information. • •

3 - 4 ••

• •

Chapter 3



Methods commonly used in preparation of estimates are outlined below:

3.3.1 Global Estimates The term Global Estimating or Order of Magnitude Estimating is used to describe a coarse or low order method of estimating involving the use of “all in” or global composite rates. The project could be considered as consisting of one estimating element only and the estimate prepared on this basis. Examples are road cost per km and bridge costs per square metre of deck area. This method has historically been used for strategic estimates, and may still be satisfactory for some projects. However, such an approach has been found not to reliably deliver the required certainty of outcome for road projects, and must be used with caution. If a Global Estimate is to be prepared (due to shortage of time or other constraints) it is essential that the composition of an historic global rate be understood prior to adoption and application of that rate to a new project. Often, global rates are based on actual completed costs and do not contain a contingency allowance, although occasionally an allowance for foreseeable risks may have been contained in the global rate. In any event, the allowances, if any, for these items contained in an historic global rate must be reviewed and adjusted, if necessary, for the new project’s particular circumstances.

3.3.2 Unit Rates Estimates The Unit Rate approach makes use of historical rates and calculated quantities to derive elemental costs. The level of project detail available at the time of estimate preparation, and the purpose for which the estimate is required, will determine the number of items into which the project is divided. RTA Project Estimating Edition 1, Revision 0


• • • • • •

3-5

Even when limited information is available, it is likely that a better result will be attained by adoption of a coarse unit rates approach rather than a global method. With a sufficient level of information, judicious selection of appropriate historical rates and provided that sufficient care is taken to ensure that the complete scope of the project is incorporated in the estimate, the unit rate approach is capable of production of estimates suitable for RTA’s requirements for detailed estimates, that is, within 10% of Actual Cost. However, care must be exercised to ensure that appropriate rates are selected and the makeup of those rates is understood.

3.3.3 First Principles Estimates The basis of first principles estimating, sometimes referred to as basic costs estimating, is replacement of the historical cost data with rates calculated specifically for the particular project. To begin a First Principles estimate, a new project is divided into the finest feasible elements. For example, concrete in a bridge deck is typically further subdivided into formwork, concrete supply, placement, finishing and curing. The plant, materials and labour requirements for each of these basic steps in construction of each element are determined, taking account of such factors as material wastage, plant cycle times and labour inefficiencies. Direct cost rates (exclusive of risk, contingency, indirect costs and margin) are calculated to develop a direct cost rate for each element, which, when applied to the calculated elemental quantities, gives a forecast direct cost. Indirect costs, or preliminaries, are calculated by consideration of time based costs and “one-off “ costs (those which are independent of the

• •

3 - 6 ••

• •

Chapter 3



duration of the project). Time based costs include site staff and their vehicles, site running costs, time related insurances and the like, whereas indirect costs include such items as mobilisation, site establishment, tender costs (for a contractor), lump sum insurances and similar items. The direct costs and indirect costs are then added, an allowance for cost escalation (if applicable) over the anticipated duration of the project applied, and margin and contingency added to give the total estimated cost. If the purpose of the estimate is to complete a schedule of rates or prices for a tender, indirect costs, margins and the like would then be spread over the tender items. First principles estimating is the method normally adopted by Contractors for preparation of detailed estimates for contract tenders. It is the most time consuming and hence costly to prepare, but has the potential to deliver the greatest certainty of outcome. Used inappropriately, however, first principles estimating can deliver results that are outside even the required range of strategic estimates.

3.3.4 Hybrid Unit Rate / First Principles Estimate Unit rates used by RTA in estimates are traditionally obtained from previous tenders for similar work. These are commonly “selling rates”, which include indirect costs and all contractor’s contingencies, margins and allowances. The sum of the elemental costs derived by the quantities and rates is the estimated cost. Since each project has unique constraints and requirements, such an approach contains inherent inaccuracies in that factors and allowances developed for a previous project (which may not be applicable or appropriate to the project being estimated) will be applied with the unit rate. An alternative approach, which uses some features of the unit rate method and some of first principles estimating, can result in increased estimate accuracy without requiring the resource investment required of a full first principles estimate. RTA Project Estimating Edition 1, Revision 0


• • • • • •

3-7

Such a method relies on the availability of direct cost unit rates - that is rates which are equivalent to those derived from the first principles approach before the application of any other costs. The process involved is to divide the project into the smallest feasible geographic or work breakdown structure elements, but without further subdivision into the basic components of plant, materials and labour. Application of direct cost rates (obtained by averaging tendered rates for similar projects in the recent past) to the elemental quantities will result in the direct cost as in the first principles method. The remainder of the estimate is then developed similar to the first principles estimate, although usually on a coarser scale. In some cases, development of rates from first principles may still be required. An example could be a road project in undulating or hilly terrain with substantial cut to fill earthworks combined with a fill deficit, requiring substantial borrow and haulage. In such a case, consideration of likely mass hauls, haul distances and plant cycle times may be required to develop custom unit rates for the project. Historical data would then be used for the remaining items of the estimate Such an estimate caters more accurately to the project conditions and constraints than the standard unit rates method, although not as well as a first principles estimate, and can therefore be expected to have an accuracy between those achieved by these methods.

3.4 Definition of Project Scope and Constraints 3.4.1 Project Scope The starting point for any estimate is definition of the project scope. Scope definition requires an understanding of the project objectives and the means by which those objectives will be delivered. In the majority of RTA projects, objectives will be delivered through construction of physical infrastructure and works. However, there are

• •

3 - 8 ••

• •

Chapter 3



some projects (for example in the Information Technology and Management areas) where delivery of a project will not involve physical works. Although in such projects there may be no physical end product, understanding of the project objectives and documentation of the project scope is equally important if a reliable project estimate is to be produced. Scope definition is normally achieved through pictorial representations and drawings, together with lists of works to be undertaken. The amount of information available, and hence the degree of scope definition achievable, depends on the stage of the project. Adequate definition of project scope is probably the most important (and often the most difficult) aspect of production of a satisfactory estimate. Inadequate or incorrect scope definition is not only the most common cause of inaccuracy in RTA estimates, but also the cause of the greatest degree of inaccuracy in estimates, particularly in the early project stages when the minimum amount of information is available.

No project estimate (of any type) should be commenced without a proper scope definition.

Estimators must resist the temptation to base estimates on poorly defined scope, which then become merely a guess, and not necessarily an informed one. It is essential that, even at strategic stage, the project scope is known and understood in sufficient detail as to allow the production of a meaningful estimate. Where information is limited, scope definition will require local knowledge of the project site and conditions and experience in and comparison with similar projects. The more common problems encountered in project scope definition are as follows.



• • • • • •

3-9

Complete Omission (or Erroneous Inclusion) of Items Examples of items which may be omitted from or erroneously included in a project’s scope are intersections or interchanges, culverts or drainage facilities, stock underpasses, drainage in cuttings, noise barriers, batter stabilisation work and subgrade improvement or strengthening. Such omissions should be avoided by checking with a schedule containing all possible items. Where estimates are based on other than global methods, the estimator must use his experience of similar projects to determine the likelihood of inclusion of such features if insufficient documented detail is available. Such inclusions should be listed as assumptions and adjusted or removed when more details become known.

Incorrect Determination of the Quantity of an Item The accuracy of determination of quantities depends on the detail of available information. However, even at the simplest level, in the often time constrained environment of estimate preparation gross errors can and have occurred. Examples are inclusion of only half the pavement quantity in dual carriageway roads or half the concrete quantity in twin deck bridges. The estimator should minimise the risk of quantity error by logically and methodically undertaking quantity calculations, and by the adoption of available quality systems.

Inclusion of Inappropriate Items. Examples of inclusion of inappropriate items are the adoption of low quality noise barriers in an urban environment and selection of an inappropriate pavement type or bridge type for a particular application.

Scope creep Scope creep is the addition of elements or items to a project, after the scope has been originally defined and agreed. If the scope has been • •

3 - 10 ••

• •

Chapter 3



initially set to satisfy the original project objectives, then scope creep would result from the introduction of additional project objectives, such as community or authority requirements which were not previously included. This is not to be confused with inclusion of items which ought to have been included in the original project scope, but were omitted either through oversight or lack of appreciation of the project.

3.4.2 Project Constraints On a project, constraints may exist for a variety of reasons. Constraints may be physical, environmental, aesthetic or regulatory, and may either introduce additional items into a project or may affect the unit rates of existing items. Examples of constraints that could potentially be omitted from the project scope are the need for air or water treatment prior to discharge; the requirement for provision of access to properties either during construction or in the final project and limitations on working hours and generated noise. A constraint that commonly causes difficulties in estimates is that of existing services and utilities, particularly those located underground, and which may require adjustment, relocation or replacement. It is often difficult to ascertain the likely extent of effects of underground (and, in some cases, above ground) services, particularly in the early project stages. An appropriate amount has to be included in the estimate as a Contingency Allowance. The Project Manager should use a checklist containing all possible constraints to avoid omissions.

3.5 Constructability and Program 3.5.1 Constructability The RTA Project Management Guide defines constructability as “the optimum use of construction knowledge and experience in planning, design, procurement and field operations to achieve overall project objectives”. This broad definition may be narrowed when applied to estimating, the objective of which is to forecast the project cost within the required accuracy for the type of estimate being prepared. Constructability in relation to estimating can be regarded as the extent to which planning, design, procurement and field operational features affect the construction cost of a project. An example is the need for sheet piling around excavation in poor ground. Depending on the time of preparation of the estimate within the life of the project, some of these factors may be known and others required to be assumed. In its most extreme form, lack of appreciation of constructability issues may result in preparation of an estimate for a project which cannot physically be built.

3.5.2 Program An appreciation of the likely project construction program is necessary in preparation of all but the most rudimentary of estimates. Potential direct cost effects of the construction program may include reductions in productivity during wet seasons, potential resources shortages at certain times of the year such as Christmas periods and the cost of maintenance of temporary facilities, such as road diversions or haul roads, during the construction period. The longer the construction program, the greater will be the effect on project cost. The indirect costs of a project will also be affected by the duration required for project delivery. A reduction in project duration is likely to be achieved at the expense of increased resources, increased • •

3 - 12 ••

• •

Chapter 3



mobilisation and establishment costs and increased time related costs per period, but with a reduction in the overall time related costs. The converse is true of an increased construction time. The optimum project time, in terms of minimisation of cost, is not necessarily obvious. For estimates which are required in outturn dollars, an appreciation of the likely construction program is necessary to apply escalation to current dollar costs in order to arrive at the outturn estimate.

3.6 Asset Management RTA’s Development Policy on Project Handover requires that Infrastructure Maintenance Branch be consulted during the concept development and detailed design phases of a project, to ensure that cost effective and appropriate asset management and maintenance functions can occur over the life of the project, and that the cost of such provisions are included in the estimated project cost. In relation to estimates, asset management may be regarded as the cost of operation, if applicable, maintenance and rehabilitation of a project. Decisions taken during development of a project will influence not only the capital cost but also the operation, maintenance and rehabilitation costs. Minimisation of capital cost is not necessarily, and is probably not, compatible with optimisation of whole of life costs. Appreciation of whole of life project costs therefore requires knowledge of all relevant operation and maintenance costs. Even where optimisation of whole of life costs is not a project objective, where reduced capital costs may take precedence over minimum whole of life cost, an appreciation of whole of life costs is mandatory in project development.

3.7 Occupational Health, Safety & Rehabilitation Occupational Health, Safety and Rehabilitation (OHS&R) issues may affect both direct and indirect cost. RTA Project Estimating Edition 1, Revision 0


• • • • • •

3 - 13

The most obvious area of OHS&R effects on direct costs is the requirement to provide a safe work area adjacent to existing roads. In addition to the cost of provision of barriers and attendants, such a requirement may affect the traffic staging during construction of a project, thereby also affecting the cost. In other areas, such as tunnelling, evolution of workplace environment requirements needs to be considered when reviewing older historical data for applicability in a new project estimate. In addition to the above effects on direct costs, RTA’s project OHS&R responsibilities and obligations must be considered when evaluating project management and supervision requirements and costs.

3.8 Environmental Issues Most RTA activities require environmental impact assessment. While preparation of the assessment will involve a cost that should be included in the estimate, it is likely that of more significance to the estimator will be the cost of compliance with the findings of the assessment or associated conditions of approval of the project by the Environmental Authorities. Of particular importance are the changes to a project that may result from either the determination process itself or from community consultation, either during the determination process or ongoing through project delivery. The environmental conditions of approval, and any resulting changes to the project, are usually not known until preparation of the final concept estimate. All preceding estimates must therefore be prepared in the absence of such detailed information, relying on requirements for similar projects. It would be appropriate to include a contingency allowance for complying with such conditions. An environmental aspect which has become quite significant in terms of project cost in recent years is that of flora and fauna compensatory habitats, mitigation strategies and associated works, where RTA is required to provide alternative habitats for species of flora and fauna when existing habitats are affected by projects. • •

3 - 14 ••

• •

Chapter 3



The extent (and hence the cost) of compensatory habitats and mitigation strategies are dependent on the extent to which species habitats are affected by the project.

3.9 Traffic Issues Depending on the type and location of the project, traffic issues which need to be considered during preparation of a project estimate may include some or all of the following: • modification or diversion of existing roads, to cater for existing traffic, on a single or multiple staged basis and maintaining an agreed level of service for users; • provision of site access for construction vehicles; • definition of allowable urban construction truck routes; and • upgrading of existing facilities as part of the project works.

The cost of traffic management may be reflected in the unit rates for other items, or may be included as a separate allowance, depending on the type of estimate and the amount of information available. It is important that the estimator understands the makeup of adopted unit rates and ensures that appropriate provision is made for the costs of traffic management, if such costs are spread over rates and not shown as a separate estimate item. The significance of traffic issues on estimated cost is project specific, and, therefore, historical unit rates from projects which required significant traffic measures may not be directly applicable to other projects without adjustment of this component of the rate.

3.10 Risk & Contingency Risk is defined as the chance of something happening that will have an impact upon objectives. It is measured in terms of consequences and likelihood (AS 4360).



• • • • • •

3 - 15

Contingency is generally defined as an unforeseen event (or risk). For estimating purposes, however, RTA refers to contingency as the sum of money allocated for dealing with unforeseen events, including those such as quantities more than anticipated

3.10.1 Risk The RTA has well established methods for identifying and assessing risks (Risk Management), which are beyond the scope of this manual. For the purposes of estimating, risks can be classified as "Known Risks" and "Unknown Risks" (a) Known Risks: A known risk is that which has been identified in the Risk Management exercise as an unplanned event that could occur in the project under consideration. The Risk Management exercise would have made one of the following decisions: (i) Adopt measures to eliminate the risk completely

- In this case, the cost of such measures should be included as a separate item in the estimate.

(ii) Adopt measures - In this case, the cost of such measures to reduce the should be included as a separate item in impact of the risk the estimate and the cost of dealing with the reduced risk event, if it eventuates, should be included as a separate item or in the contingency allowance. If the cost is included in the contingency allowance, the estimate should contain a note clarifying this amount.

(iii) Do Nothing-

- In this case, the cost of dealing with the risk event, if it eventuates, should be included either as a separate item or in the contingency allowance. If the cost is included in the contingency allowance, the estimate should contain a note clarifying this amount.

• •

3 - 16 ••

• •

Chapter 3



The main purposes of showing the estimated costs for dealing with risks, separately, are: (i) the items can easily be changed into Provisional Items for tendering purposes; and (ii) actual costs of variations arising from the risk events can be traced back to the allowances made in the estimates. Examples of known risks are: (i) Sulphate Attack (High likelihood, severe consequence) In this case, the Risk Management exercise may have led to deciding on adopting measures to eliminate the risk completely. (ii) Community complaint on construction noise levels (Medium likelihood & consequence) In this case, the Risk Management exercise may have led to deciding on adopting measures to reduce the impact such as constructing a temporary earth mound.

(iii) Pile toe levels lower than expected (Medium likelihood & consequence) In this case, the Risk Management exercise may have led to deciding on adopting the "Do Nothing" option. (b)Unknown Risks These are risks where existence and degree of impact on the project are both uncertain. Examples of such risks are Force-Majure events such as flooding, earthquake, cyclone, etc., political events such as



• • • • • •

3 - 17

funding cutback, labour unrest, etc., and human errors such as design errors, accidents caused by human factors, etc. The Risk Management exercise may not have determined the probability or the severity of such risks. Even if these have been determined, their reliability would be in question. For example, the probability of an earthquake occurring in Sydney could have been decided as, say, 1 in 10,000 prior to the earthquake in Newcastle in 1990. Immediately after that incident, it could have been decided as, say, 1 in 10. Now, some ten years after the incident, it could be decided as, say, 1 in 1,000. Similarly, the prediction of the severity of the incident would also be unreliable. The predictions would also depend on the bias of the decision makers - A person who has experienced a similar incident would tend to predict a higher probability than that predicted by others and a severity similar to the one he/she has experienced. As such, it would be difficult to arrive at reasonable contingency allowances. It should, however, be born in mind that the tendency to be riskaversive would lead to unrealistically high estimates caused by adding contingency allowances for all or most of the identified unknown risks. A common sense approach and consideration of how the previously completed projects have suffered from unknown risks would give rise to reasonable contingency amounts.

It should also be noted that the probability of the project being affected by all of the identified "unknown risks" would be next to nothing. If a large number of risks are identified, especially for a large complex project, a realistic contingency figure could be arrived at by carrying out a Monte Carlo simulation. This process, however, would require feeding in minimum, maximum and most probable costs of dealing with each risk and the type of distribution between minimum & maximum values for each risk. The outcome is a range within which the project estimate will lie. The process is, therefore, sometimes known as “range estimating”, and is • •

3 - 18 ••

Chapter 3



undertaken with software developed for the purpose. Essetnially, a definitive estimate is prepared, to which risk probabilities are applied and a range estimate developed. Software used for quantification of risks and the development of range estimates includes: • Crystal Ball, which uses Microsoft Excal spreadsheets for input; • @Risk, which also uses Microsoft Excel spreadsheets for input; and • Analytica. Further details of these software packages and the way in which these are used are contained in Chapter 10.

3.10.2 Contingency The contingency allowance for the different items should be reviewed at each stage of the estimate and adjusted, if necessary, depending on the predicted probability and severity of the risk events at those stages. Further details and recommended levels of contingency for the various project stages are contained in Sections 5, 6 and 7. It must be noted that the contingency allowance is not for changes to the project scope, but only for unforeseen events which occur within the existing project scope. In the event that the project scope is changed, a new estimate must be prepared, with a new definition of project scope and a level of contingency applicable to the revised scope.

3.11 Value Engineering The process of value engineering, or value management, is described in the following documents; AS/NZS 4183 “Value Management”; NSW Government “Capital Works Investment Value Management Manual”; and RTA Project Estimating Edition 1, Revision 0


• • • • • •

3 - 19

Value Management Guide prepared for RTA by the product Evaluation Unit, NSW Public Works Department. Value management is defined in AS/NZS 4183 as “a structured, analytical process which seeks to achieve value for money by providing all the necessary functions at the lowest total cost consistent with required levels of quality and performance.” It is clear from the above definition that, at the heart of value management is the provision of reliable estimates on which value management decisions can be based. It is equally important to adjust the estimate(s) to reflect the decisions taken during the Value Management process. While it is not the function of the estimator to make decisions regarding the relative merits of different project options, a properly considered and prepared estimate should highlight any areas of the project which, in comparison with other similar projects, do not appear to provide a value for money solution. Further, the concept of “designing to a cost” should be borne in mind during preparation of detailed designs.

3.12 Use of Historical Cost Data RTA has over time, through receipt of tenders and preparation of RTA’s own estimates for projects, amassed a wealth of data on rates, prices and costs. Often, such data is useful in the production of new estimates. Inappropriate use of such data can, however, have serious consequences in the accuracy and reliability of the estimate. There are four major factors which must be considered in deciding whether an historical rate or price is applicable to a new estimate.

Chapter 3



Direct Costs Direct costs are those involved in actually constructing a work item. These costs normally include materials, plant and labour up to the level of leading hand/ganger. It is not always apparent from the title of a rate precisely what direct work items are included. For example, “concrete” may include only supply and delivery of concrete, or also placing and finishing, or it may be a composite rate including formwork construction and stripping, reinforcement, supply, placing, finishing and curing of concrete. An allowance for wastage may or may not be included. Similarly, “excavation” may include excavation only, or haulage, stockpiling and spoil disposal, or all of these, environmental protection and an allowance for harder material excavation. In addition to the above, historical cost data may contain risk and contingency allowances specific to a particular project, or alternatively may make no allowance for these.

Indirect Costs Indirect Costs include such items as site overheads and allowances for non-work related items. Typically, submitted tenders do not list such items as preliminaries, overheads and profit separately. Therefore, submitted tender rates normally include indirect costs. Such rates are sometimes referred to as ‘sell(ing) prices or rates’. In preparation of estimates, particularly more detailed estimates such as those prepared from first principles or the hybrid approach described earlier, the rates adopted often exclude indirect costs. The estimate is compiled on the basis of direct cost rates, with indirect costs added as a separate item in the estimate total. Prior to the adoption of historical cost data, it is necessary to understand the makeup of the data, and in particular whether the data includes or excludes indirect costs. RTA Project Estimating Edition 1, Revision 0


• • • • • •

3 - 21

Overheads and profit Both direct and indirect costs will be subject to the addition of amounts for the tenderer’s corporate overheads and profit (margin). However, it is not always possible to identify the amount of such allowances. In using historical data, the estimator must be aware of the market conditions prevailing at the time of the tender (competitive market conditions lead to a reduction in allowances for overheads and profit) and the possibility that the allowances for overheads and profit have not been equally spread over all the rates (Contractors sometimes adopt a practice known as ‘front end loading’ for ensuring good cash flow at the beginning of a project).

Age of the Data Costs for the same item of work vary with the passage of time (usually increasing), and the older the data the less reliable it will be. An appropriate allowance for inflation must be made whenever historical data is used.

3.12.1 Application of Historical Data While historical cost data is a valuable asset, careless or inappropriate adoption of such data can, and has, led to significant errors in estimates. Prior to the use of such data it is essential to be confident that the makeup of the data is known and that the data is applicable to the estimate under preparation.

3.13 Quality Assurance in Estimating Estimating is a task in which errors can easily occur, and is also one for which the delivered product does not necessarily provide evidence of

the rigour of the processes adopted. The estimating process is one that will benefit from the adoption of Quality Assurance principles.

The Project Management System (PM21) Manual is applicable to estimate preparation for all infrastructure development projects managed by Project Management Services Group within RTA’s Client Service Directorate.

The following procedures are applicable to the preparation of RTA estimates: Procedure for Preparation, Concurrence, Approval and Acceptance of an Estimate of Cost (RTA-CSD-PMS-PR-P-91); Procedure for Preparation of a Strategic Cost Estimate (RTA-CSDPMS-PR-P-92); Procedure for Preparation of a Concept Cost Estimate (RTA-CSDPMS-PR-P-93); and Procedure for Preparation of a Detailed Cost Estimate (RTA-CSDPMS-PR-P-94). Chapters 5, 6 and 7 of this manual provide further descriptions and guidance on the processes to be adopted for strategic, concept and detailed estimates respectively. In addition to the above procedures, flowcharts, checklists and proformas are included in this manual in the appropriate sections. Use is to be made of these as far as possible during preparation of an estimate, or, if necessary, these should be used as a basis for the development of project specific versions. Reality checks and peer review are also be considered to form part of the quality assurance process.



• • • • • •

3 - 23

Reality Checks and Peer Review Reality checks must be carried out for every estimate by the estimator prior to presentation of the estimate for peer review. Reality checks, also called gross or sanity checks, are intended to ensure that the estimate is within expected and reasonable limits. Such checks are based on comparisons of estimated costs with historical data, and are generally undertaken on a global basis. The Standard Summary Structure for Development Project Estimates requires reality checks based on project cost per km of road and per lane-km of road, earthworks costs /m3, pavement costs /m2 and structure cost /m2 of deck area. Even when reality checks are not a formal requirement, it is good estimating practice to undertake a reality check on every estimate, to both verify the appropriateness of the estimate and also to contribute to the available database of estimating knowledge within RTA. RTA policy is that peer review be carried out wherever possible by a person of the next or same level of seniority to the person responsible for preparation of the estimate. While peer review would practically involve a lesser level of detail than that involved in preparation of the estimate, it is essential that the review focuses on the major items in sufficient detail that the validity of the estimate is verified.

3.14 Guidelines for Preparing Estimates It has been noted that there is lack of consistency in (a) the grouping of major infrastructure items (b) the calculation of reality check rates, when preparing estimates for various projects. These guidelines clarify the grouping and the figures to be used for reality check calculations.

3.14.1 Earthworks The following items should be included under this sub-heading: • • • • • • • •

Clearing & Grubbing Remove & Stockpile Topsoil General Earthworks (Cut/Fill) Earthworks (Cut to Waste) Imported (Borrow) Material Unsuitable Material (to Spoil) Selected Material Earthworks for Batter Protection

The Reality Check calculation for Earthworks should be carried out by using the dollar amounts and quantities for General Earthworks (Cut/Fill), Earthworks (Cut to Spoil) and Imported (Borrow) Material only.

3.14.2 Structures The following items should be included under this sub-heading: • • •

Bridges Structural Retaining Walls, e.g. Cantilever type walls Structural Culverts (cast in-situ)

The reality check calculation for Structures should be carried out by using the dollar amounts for Bridges and the deck area for Bridges only. For calculating the deck area of a bridge, the length should be measured between the inside face of abutment curtain walls and the breadth should be measured between the inside face of the outer parapets. Thus any footpath, if provided, would also be included in the deck area. Note: 1. Approach slabs, Retaining Walls and Structural Culverts are not to be included in Reality Check calculations. 2. Precast Box Culverts and Pipe Culverts are to be included under "Drainage" RTA Project Estimating Edition 1, Revision 0

ESTIMATE COMPONENTS

CHAPTER0

4.1 Summary This chapter considers the common components of all RTA estimates, including: • • • • • •

Project Development costs; Detailed Investigation and Design costs; Property Acquisition costs; Infrastructure Construction costs; Utilities costs; and Handover costs.

The components are defined and examples given, in order that a high degree of consistency will be maintained through all RTA estimates.

4.2 Project Development Costs These costs include activities in the Option Investigation, Concept Design and Design Development and Approval phases of the project. Project development costs may include: • • • • • • • •

Route selection; Advice from other government agencies; Preparation of EIS; Acid or contaminated soils investigations and review; Technical input from the project team; Concept review by RTA Operations; Preparation of Representations Report; Preparation of project estimate;


Estimate Components Issued December 2001

• RTA Project Management; and • RTA Client Representation.

4.3 Detailed Investigation and Design Costs These costs include all activities in the Detailed Design and Implementation phase between the end of the Design Development and Approval phase and commencement of tendering (with the exception of property acquisitions and public utilities). Detailed design and investigation costs may include: • • • • • • • • • • • • •

Geotechnical investigations; Hydraulic and hydrological studies; Fauna and flora impact studies; Advice from other government agencies; Utilities locations and searches; Detailed project design and design review; Technical input from the project team; Preparation of project environmental plans; Preparation of contract documents; Safety audits; Detailed estimate preparation; RTA Project Management; and RTA Client Representation.

4.4 Property Acquisition Costs Estimated property acquisition costs must be obtained from RTA’s Property Section, for both metropolitan and rural property acquisitions. Cost estimates supplied are generally the actual estimated land acquisition costs at the time the estimate is prepared by RTA’s Property Section, with no allowance for contingency or for possible future land cost variations. An appropriate contingency must be

applied, having regard to the expected timing of acquisition of the property and the complexity of the acquisitions. Generally acquisition complexity, and hence the appropriate level of contingency, is higher in urban and particularly metropolitan areas (where land values are more volatile and property adjustments are numerous) than in rural areas. The value of all land required for the project, either as the acquisition cost for newly acquired land, or the potential sale value for previously acquired land, must be included as a project cost. In the case of land which is required only for the period of construction, and which is acquired and subsequently disposed of rather then leased for the duration of project construction, a residual land value should be credited against the project cost. In some cases this may be the same as the acquisition cost of that land, but often will be less than the acquisition value due to the proximity of the project works and possible land rezoning. Property acquisition costs may include: • • • • • •

Property valuations; Property surveys; Property acquisitions; Property adjustments; RTA Project Management; and RTA Client Representation.

Property acquisitions may include: • The actual area acquired or utilised permanently for the project, including sub-surface easements if applicable; • Compensation paid to land owners in respect of effects of the project on the owners’ land; • Any land which may be permanently or temporarily required for compensatory habitats; • Contractors’ work and site areas (if provided by RTA) including provision for site offices, temporary environmental works, traffic diversions and the like;



• • • • • •

4-3

• RTA’s site office and facilities areas, if separate from the Contractor’s area; • Land required for any RTA works to be undertaken as part of the project; and • The residual value of land temporarily acquired, or made available by demolition of existing infrastructure replaced by the project works.

4.5 Infrastructure Construction Infrastructure construction includes the production or construction of base infrastructure, environmental works, general activities and property adjustment. Infrastructure costs may include; • Construction cost of infrastructure; • Technical advice from RTA ( eg Bridge Branch and Pavement Branch); • Construction audits, site management and surveillance; • RTA Project Management; and • RTA Client Representation

4.6 Utilities Costs Utilities costs include all adjustments, replacements, relocations and the like which are required as a consequence of the project, whether undertaken by the responsible authority, a contractor engaged by that authority, or undertaken by RTA either as part of the main contractor’s works or by separate contract. In some cases, utilities adjustments may be undertaken partly by the project main contractor and partly by others, outside the main contract scope of works but still within the overall project scope. In such circumstances, care must be taken to ensure that the correct scopes of utilities adjustments are contained in the main contract scope and in the scope of other works, and that the scope description makes clear the division of utilities adjustments.

Chapter 4



In the Sydney metropolitan area, some services, in particular old sewers and water supply tunnels, are heritage classified. Project works which could affect these services, such as tunnelling, can require extensive local additional work for protection of such services, the cost of which may be significant. Also in the Sydney metropolitan area are major electrical services owned by railways authorities, and which are unlikely to be detected in an enquiry to the electrical supply authorities. It is often difficult to ascertain the potential costs to RTA due to effects of a project on existing utilities. For example, a utility authority may not agree to meet the cost of relocation of a utility which was not supposed to be in the vicinity. An appropriate contingency, which is likely to be among the highest adopted for the project, particularly in the early stages of a project and in metropolitan areas, must be applied. Utilities costs may include: • Telstra, Optus and other communications carriers adjustments; • Electrical services adjustments; • Water and sewerage adjustments, including possible protection of heritage services; • Gas mains adjustments; • RTA Project Management; and • RTA Client Representation.

4.7 Handover Costs Handover costs are those incurred by RTA when delivery of a new asset causes the management of either an old asset, previously the responsibility of RTA, or part of the new asset to be transferred to a body other than RTA (eg Local Council). Handover costs occur, for example, when a new section of road replaces an existing section, with the existing section becoming part of the local road network under the management of the local council. In such circumstances, RTA may be required to refurbish or resurface the existing road, install signage prior to its acceptance by the council or to RTA Project Estimating Edition 1, Revision 0

contribute to the net present value of the future maintenance of the existing road. In some cases handover costs may occur when an existing structure is retained for heritage or other reasons and RTA is required to contribute to the ongoing maintenance costs. Examples of such costs are the retention of the old Glebe Island Bridge on completion of the Anzac Bridge and the retention of the Hawthorne Canal bridge on completion at the City West Link. A further example of handover costs occurs when roadside facilities are provided on a new section of road, such as rest areas and viewing points, the maintenance of which is the responsibility of the local council. In such cases, handover costs consist of the cost of preparation of maintenance manuals, setting out RTA’s requirements, for the areas. Handover costs may include: • Refurbishment of old assets by local councils; • Contribution to maintenance costs of existing structures; • Preparation of maintenance manuals for project maintenance by others; • Project data and reporting; • RTA Project Management; and • RTA Client Representation

STRATEGIC ESTIMATE

CHAPTER0

5.1 Summary This chapter sets down the process for preparation of a Strategic Estimate.

5.2 Overview There are 3 key stages to the preparation of a Strategic Estimate. These are: • Preliminary Project Appreciation Stage; • Estimate Establishment Stage; and • Review and Approval Stage.

Commit sufficient time and resources to each of these stages. Failure to follow a planned process of estimate preparation will lead to estimates of doubtful accuracy.

It is recommended that an estimate plan be prepared by the Project Manager, to ensure that proper resources are available and are applied to preparation of the estimate.

5.3 Preliminary Project Appreciation Stage The following paragraphs indicate the activities that will be undertaken in this interrogative stage:


Strategic Estimate Issued December 2001

• • • • • •

5-1

5.3.1 Estimate Programme Approximately 1 week should be allowed for the preparation of a Strategic Estimate (assuming that all information is available).

5.3.2 Data Collection The estimator must be provided with all relevant information. This will include: • An understanding of the proposed contracting strategy for the project (for example: design and construct; construct only; single construction contract; multiple contract packages and the like); • A detailed description of the scope of the project. This is an essential component in ensuring the accuracy of the estimate. A sample cost estimate scope is contained in Appendix 5.1; • A complete set of current drawings; • Details of the costs expended on the project to date; and • Any other available information, such as aerial photographs, computer generated quantities, property valuations, hand over cost estimates and the like.

5.3.3 Project Programme A project development programme is to be prepared. This should indicate all significant activities and milestones, together with an approximate construction programme.

5.3.4 Quantities Quantities are likely to be of a very approximate nature and will be taken-off by the estimator, based on his understanding of the project scope.

5.3.5 Site Visit A site visit should be made by anyone on the estimating team who is unfamiliar with the project.

Chapter 5



5.3.6 Construction Methods For significant items (such as earthworks or road pavement), the estimator is to determine the probable construction methods that will be adopted by the successful tenderer.

5.4 Estimate Establishment Stage This is the stage where the project estimate is actually produced. Before computations commence, the estimator must have regard to RTA’s requirements as to final presentation of the estimate, and the Work Breakdown Structure and Summary required. A sample work breakdown structure is given in Appendix 5.2. The following paragraphs indicate the activities that will be undertaken for a Global Estimate:

5.4.1 Understanding Historical Data Historical data will be collected and analysed to determine: • Market conditions prevailing at the time of the tender from which the data has been collected; • Any peculiarities of the project from which the data has been collected; • If front-end loading has occurred; and • An approximate allowance for contractors on and off site overheads and profit (if available).

5.4.2 Adjusting Historical Data Historical data is to be adjusted to bring it in line with the requirements of the project being estimated, including (if necessary): • • • •

An adjustment for inflation; An adjustment for site conditions; An adjustment for front-end loading; and An adjustment for contractors on and off site overheads and profit.



• • • • • •

5-3

5.4.3 Cost Estimate The estimate is calculated, by multiplying the global quantities by rates deduced from historical data, or from multiplying the coarse quantities by the unit rates deduced from historical data.

5.4.4 Contractors Overheads, Risk and Margin Generally the contractors overheads, risk and margin is included within the global rates adopted earlier and no further adjustment is required.

5.4.5 Project Development Costs Project development costs are defined in Chapter 4. At the time of preparation of a Strategic Estimate, these costs have probably not been incurred and may be estimated from past experience.

5.4.6 Detailed Investigation and Design Costs Detailed investigation and design costs are defined in Chapter 4. At the time of preparation of a Strategic Estimate, these costs have not been incurred and may be estimated from past experience.

5.4.7 Property Acquisition Costs Property acquisition costs are defined in Chapter 4. Property acquisition costs must be obtained from RTA’s Property Section. Allowances must be made for known property adjustments.

5.4.8 Hand over Costs Hand over costs are defined in Chapter 4. A detailed estimate of these costs is to be prepared.

5.4.9 Risk & Opportunity Issues of risk and opportunity are considered in Chapter 3. Some of the available software for use in quantification of risk and opportunity is listed in Chapter 10.3.

It is mandatory that a risk analysis be prepared for strategic cost estimates.

5.4.10 Contingency Contingency is considered in Chapter 3. Appropriate contingencies must be added to each component of the project estimate. At strategic estimate stage, contingencies in the range of 35% to 50% are appropriate. Contingencies outside this range must be justified.

5.5 Review Prior to commencement of the Concurrence, Approval and Acceptance procedure, the Project Manager should arrange a peer review of the estimate. This should follow a structured format and be documented.

5.6 Concurrence, Approval and Acceptance All strategic estimates are subject to concurrence, approval and acceptance as detailed in Chapter 2. The procedure is detailed in the following flowcharts. [Extract from PMS 21 Manual.] RTA Project Estimating Edition 1, Revision 0

SAMPLE COST ESTIMATE SCOPE

CHAPTER0

• • • • • •


• • • • • •

Scope of Work for Robinvale – Euston Bridge Replacement Project The proposed work involves construction of a new crossing over the Murray River and flood plain at Robinvale. The project extends from the Murray Valley Highway in Robinvale, (Victoria) to the Sturt Highway in NSW, connecting either in or near Euston. The project is required to provide a two-lane, two-way flood free crossing of the Murray River and floodplain, and is to incorporate provision for cyclists/pedestrians and river navigation. Six potential alignments identified at a Value Management Study held in Robinvale during March 1999 are being investigated in detail, with the aim of selecting the preferred option.

(i) Assumptions The following is assumed, with resultant risks: *

Bridge and approaches are technically feasible to build using normal design and construction techniques.

* The afflux created by the existing crossing will be acceptable to DLWC and MDBC. (The estimates are based upon bridge lengths and waterway areas that create approximately the same afflux as that created by the existing crossing). *

Native Title and indigenous issues will not prevent construction.

*

Heritage status of existing bridge will not impact on the proposal (eg for Options A, D and E, a modern bridge will be permitted near the existing bridge, if the existing bridge is to be retained for heritage reasons).

*

An allowance of $1M for demolition or other disposition of the existing bridges will be adequate. (No allowance has been made for refurbishment or ongoing upkeep of the existing bridges).

*

At-grade intersections will be adequate.

*

Current standards providing 3.5m wide lane widths and lm and 2m shoulders on the bridges and approaches respectively will be adequate.

*

A combined pedestrian/cyclist pathway is required on the section of the bridge that crosses the Murray River, with the remainder of the pathway being at ground level.

*

The following widths have been assumed for estimating and comparison of the options: Bridge with combined pedestrian cycleway - total width 12.5m comprising two 3.5m wide travel lanes, lm wide shoulders, 2m wide combined pedestrian/cycleway. Allowing for traffic barriers and a pedestrian fence, this results in a total width of 12.5m, and a width between kerbs for estimating purposes of 11.5m. Bride without pedestrian/cycleway - total width l0m comprising two 3.5m wide travel lanes, 1m wide shoulders and 0.5m wide allowances for traffic barrier systems. Width between kerbs for estimating - 9m.

Approach roads - formation width of 11m comprising two 3.5m wide travel lanes, 2m wide shoulders and lm rounding on the edge of the formation (verge material).

(ii) Preliminary Details of each Option Option A The alignment of this crossing is • •

river and on the main floodplain section - adjacent to and on the western side of the existing crossing; north of Approach Bridge No 2 - retain existing alignment.

PACIFIC HIGHWAY. UPGRADE FROM MOORLAND TO HERONS CREEK. STRATEGIC ESTIMATE.

PURPOSE This memorandum formally seeks concurrence to the Strategic Estimate for the proposed Upgrade from Moorland to Herons Creek. The Strategic Project Estimate ranges in an amount from $150 to 180 million. BACKGROUND The project involves upgrading of a 21.9km section of the Pacific Highway by widening, duplication and/or deviation from Camp Obadiah to the existing dual carriageway at Herons Creek, between 36.6km and 58.5km north of Taree. The study area for the proposed upgrade is to include the townships of Johns River and Kew. Refer Attachment ‘A’. To the south, the EIS for the Coopernook to Moorland project has been prepared and placed on public exhibition. The two projects interface in the vicinity of Camp Obadiah. To the north, this project ties into the existing dual carriageway on the Herons Creek Deviation, which was opened to traffic in July 1998. The project interface is located at the commencement of the dual carriageway section near Bobs Creek Road at Herons Creek. The Pacific Highway Office has previously engaged the RTA Operations Technical Services Branch to undertake strategic concept development for this project. The strategic concept development was carried out, firstly, in order to examine the broad engineering, environmental and planning constraints which would apply to an upgrading of this length of the Pacific Highway. Secondly, the strategic project development work included development of two possible upgrade options to establish the feasibility and Strategic Cost Estimate for the project. A Strategic Concept Design Report (February 2000) has been prepared by the RTA Operations Technical Services Branch detailing strategic concept design development, design input data gathered and broad environmental, visual and geotechnical considerations. Formal Project Development Work for this project has recently commenced. The firm of Ove Arup and Partners Pty Ltd has been commissioned to provide the project development services for this project which include route selection, development of the preliminary engineering design, preparation of the Environmental Impact Statement (EIS) and post EIS activities. This Strategic Estimate has, therefore, been prepared in consultation with Ove Arup and Partners.

Community consultation has commenced with public meetings to introduce the study team and describe the scope of the project to the local community held at Johns River and Kew in October 2000. A Planning Focus meeting was also held in October 2000 at Port Macquarie. Refer Attachment ‘B’. It is expected that there will be considerable community interest in the development and delivery of this project. To afford the broader community the opportunity to make a demonstrable input to the process, and to ensure that the requirements and aspirations of the community are adequately and appropriately addressed, two Community Focus Groups have been established. The initial meetings were held in December 2000 at Johns River and Kew. Issues such as flora and fauna, waterways and wetlands, water quality, geotechnical, land use and access, social impact, noise, visual amenity and urban design will be of major importance to the project. At this stage, the study area has been defined and a considerable number of preliminary route options have been examined and introduced to the Community Focus Groups. These preliminary route options have been developed on the basis of desktop and preliminary investigations only and are yet to be refined by the project team and presented to the broader community. ESTIMATE DETAILS For the purpose of defining the likely range for the Strategic Project Estimate, three (3) option scenarios have been costed and are detailed as Attachment ‘C’. These three option scenarios have been chosen as they are considered to best represent the likely range of feasible route options that will ultimately be presented to the community. The alignment options for these Strategic Estimates are depicted in Attachment ‘D’ and include: 1.

Estimate ‘A’ – (Lowest Cost $150M.) - 110km/hour design upgrade along the entire existing highway corridor, with the exception of an 80km/hour design through the townships of Johns River and Kew. Traffic Signals have been allowed at the intersection with Ocean Drive/Kendall Road. Total length 21.9km;

2.

Estimate ‘B’ - (Likely Mid Range Cost $170M.) - 110km/hour design upgrade generally along the existing highway corridor, with an Inner Western Bypass of Johns River and an Inner Western Bypass of Kew. Total length 22.0km; and

3.

Estimate ‘C’ - (Likely Highest Cost $180M.) - 110km/hour design upgrade generally along the existing highway corridor, with an Inner Eastern Bypass of Johns River and an Outer Western Bypass of Kew. Total length 22.5km.

These Strategic Estimates take into consideration the Strategic Concept Design work completed by RTA Operations in February 2000, and the more recent preliminary Route Selection work currently being carried out by Ove Arup and Partners. An extract from the RTA Operations Strategic Concept Design Report, summarising the broad environmental issues identified and likely to impact upon the project, is included as Attachment ‘E’.

This improved understanding of the broad environmental project issues, has lead to the inclusion in the strategic estimates of, for example, likely requirements by the National Parks and Wildlife Service for the provision of compensatory habitat. It has also led to adoption of a lower contingency allowance on some cost items associated with the delivery of the project. The Strategic Estimate Subsidiary Sheet documentation incorporates numerous notes detailing assumptions and clarification of some of these issues. Geotechnical features of the project include soft soil and potential acid sulphate soil issues in the vicinity of the Stewarts and Camden Haven Rivers, and a number of hard rock cuttings located north of the Stewarts River bridge which may require some blasting. Geotechnical investigations will be ongoing, with an extensive amount of preliminary and detailed assessment being carried out during both the Option Investigation Phase and the Design Development and Approval Phase. The Strategic Estimates reflect these requirements and also include some allowance for “fine tuning” of the geotechnical investigations during the project Detailed Design and Implementation Phase. Corporate Contributions have been applied to the relevant cost items at a rate of 10% and have been depicted on the Strategic Estimate Subsidiary Sheets. These Corporate Contributions have been included in each item amount (excluding contingency), in the Strategic Estimate Summary Sheets. COMPARISON WITH OTHER PROJECTS The estimated cost for this project is low relative to other projects being undertaken under the Pacific Highway Upgrading Program.

Reasons for the relatively low estimated cost for the Upgrade from Moorland to Herons Creek include: (a)

With the exception of the bypass route options which may be required around the townships of Johns River and Kew, the project is expected to retain a large proportion of the existing highway asset. The majority of the proposed highway duplication, is likely to take place primarily along the existing highway corridor.

(b)

At this stage, the proposed lengths of the preliminary bypass route options for Johns River and Kew are relatively short given the overall project length. Therefore the project cost rate per km, is generally low with the range of likely estimated costs, being directly attributed to the various Johns River and Kew bypass route option scenarios.

(c)

Accessibility for construction plant and provision for existing traffic are expected to be straightforward due to the proximity of the existing highway formation.

OTHER SUPPORTING DATA Corporate Contributions:

Corporate Contribution has been set at 10% for this Strategic Estimate. (Refer Subsidiary Sheet).

Project Development:

Represents 5.2% of total project cost. An amount has been included for the RTA Operations Strategic development work already completed. The majority of the Geotechnical Investigation has been allowed up front prior to Detailed Design and Implementation.

Investigation and design:

Represents 2.7% of total project cost. Majority of design will be relatively simple duplication within existing highway corridor. Detailed issues will need to be addressed for the townships of Johns River and Kew. A small allowance is included for “fine tuning” of the geotechnical investigations already completed during the Option Investigation and the Design Development Phase.

Typical Cross Section:

This estimate is based on retaining the existing highway as one carriageway and constructing a new carriageway beside the existing. Duplication may involve widening both sides of the existing highway within the townships of Johns River & Kew.

Acquisition:

Will be impacts on properties along the existing corridor and some major acquisitions may be required through Johns River and Kew including commercial sites.

Utilities:

Location of major plant is known from earlier investigations. Allowance is considered reasonable.

Earthworks:

Quantity based on 1999/2000 RTA Operation Strategic Concept work. Rate reflects generally easy work without major traffic issues.

Drainage:

Due to the surrounding topography, cross drainage requirements are less than typically encountered on Pacific Highway projects, with very few crossings other than major structures. This allowance is considered reasonably generous.

Pavement:

Assumed 150mm concrete/200mm Asphalt. Conservative assumption to overlay existing with 200mm Asphalt.

Structures:

See above. $2,000/m2 has been adopted as a general rate representing an average when considering the various classes of structures required.

Fauna/ Compensatory Habitat:

Minimal provisions assumed. Likely fauna movements are between National Park areas where the existing road corridor is used.

Noise Attenuation:

Quantities adopted on the basis that provisions will likely be required at Johns River and Kew due to upgrading along the existing alignment with the provision of additional travel and turning lanes.

Represents 2.3% of total project cost. Majority of design will be relatively simple duplication within existing highway corridor. Detailed issues will need to be addressed for the township bypasses of Johns River and Kew. A small allowance is included for “fine tuning” of the geotechnical investigations already completed during the Option Investigation and the Design Development Phase.


With the exception of the Johns River & Kew bypass sections, the project estimate is based on retaining the existing highway as one carriageway and constructing a new carriageway beside the existing.

Acquisition:

There will be impacts on properties along the existing corridor and some major acquisitions may be required for new rural corridors (approx. 5km) for the bypasses of Johns River and Kew. Allowance has been made for major impacts on the eastern part of the Camden Haven Golf Course.

Utilities:


Earthworks:

Quantity based on 1999/2000 RTA Operation Strategic Concept work and some preliminary route investigation by OVE ARUP. Rate reflects generally easy work without major traffic issues.

Drainage:


Pavement:

Assumed 150mm concrete/200mm Asphalt. Conservative assumption to overlay existing carriageway with 200mm Asphalt.

Structures:



Minimal provisions assumed. Likely fauna movements are between Nation Park areas where the existing road corridor is used.

Noise Attenuation:

Quantities adopted on the basis that provisions will likely be required at Johns River and Kew. Amount reflects the proximety of the proposed bypass routes to potentially impacted areas.

Represents 2.1% of total project cost. Majority of design will be relatively simple duplication within existing highway corridor. Detailed issues will need to be addressed for the township bypasses of Johns River and Kew. A small allowance is included for “fine tuning” of the geotechnical investigations already completed during the Option Investigation and the Design Development Phase.


With the exception of the Johns River & Kew bypass sections, the project estimate is based on retaining the existing highway as one carriageway and constructing a new carriageway beside the existing.

Acquisition:

There will be impacts on properties along the existing corridor and some major acquisitions may be required for new rural corridors (approx. 6.5km) for the bypasses of Johns River and Kew. Allowance has been made for a significant number of Residential/Urban impacts within Johns River and for major impacts on the western part of the Camden Haven Golf Course.

Utilities:


Earthworks:

Quantity based on 1999/2000 RTA Operation Strategic Concept work and some preliminary route investigation by OVE ARUP. Rate reflects generally easy work without major traffic issues. This option is considered to be the longest practical western bypass route around Kew.

Drainage:


Pavement:

Assumed 150mm concrete/200mm Asphalt. Conservative assumption to overlay existing carriageway with 200mm Asphalt.

Structures:



Minimal provisions assumed. Likely fauna movements are between Nation Park areas where the existing road corridor is used.

Noise Attenuation:

Quantities adopted on the basis that provisions will likely be required at Johns River and Kew. Amount reflects the proximety of the proposed bypass routes to potentially impacted areas.

MOORLAND TO HERONS CREEK

STRATEGIC CONCEPT DESIGN REPORT (EXTRACT) SUMMARY OF ENVIRONMENTAL ISSUES Land Use and Accesses

• The highway passes through the townships of Kew and Johns River. The villages of Rossglen and Herons Creek are close to the highway on the western side. • Land adjacent to the highway has a variety of uses including grazing, National Park, State Forest, North Coast railway and SEPP 14 wetlands. Within the towns there are residential properties, motels, shops, service stations and a hotel. • The terrain is generally undulating. The highway skirts the foothills of the Brother Mountains and crosses the flood plains of the Stewarts and Camden Haven Rivers. • Depending on the Preferred Route adopted, a number of properties would be affected by strip acquisition and a number of houses at Johns River would require demolition or relocation. Consideration of the possibility of the highway being deviated further to the west of Johns River would require the need to address the impact of such a deviation on the future development west of Johns River, as proposed by Greater Taree City Council. • Ongoing consultation will be required with Taree and Hastings Councils regarding the project and, specifically, proposed developments that might impact on, or be impacted by, the project. • Controlled access conditions along the upgraded highway will be critical to ensuring its ongoing functionality. • Direct access to properties (and some side roads) from the opposite carriageway will be denied. In such cases access will be restricted to left turn in / left turn out. Provision for U-turns will be made at appropriate facilities to be incorporated into the project. Further design development will be required before the impacts of loss of direct access can be fully assessed. This design development will draw on input from the community consultation process. • Proposals at both Kew and Johns River may impact on the access to and operation of some businesses and private residences. • Taree City Council operates under a performance-based Local Environmental Plan. Under the LEP, proponents are required to demonstrate that their development is consistent with the LEP aims and objectives. The aims and objectives are structured as follows: 1. LEP aims, 2. general zoning objectives, and 3. specific zone objectives.

Pacific Highway – Upgrade from Moorland to Herons Creek Strategic Concept Design Report (Extract)

January 2000

Attachment E Flora and Fauna

2

• There are areas on both sides of the highway that are likely to be identified as significant habitat areas. Part of Middle Brother State Forest was gazetted as National Park on 26 February 1999. There is also a large diversity of habitat types, including: wetlands, eucalypt woodland, open forest, casuarina forest, melaleuca forest, agricultural land, riparian vegetation, potential closed forest and wetland areas containing large stands of Juncus sp. There is a large SEPP 14 wetland (Coastal Wetland 544C) east of the highway north of Camden Haven River. • Acquisition and clearing of some small portions of the Middle Brother State Forest will be required to enable construction of either of the Options developed to date. Further investigation will be required to determine if any of these portions are part of the recently declared Yoorigan National Park. • The vegetation within the road reserve along the project length is generally of moderate to high value. • No detailed threatened flora and fauna studies have been undertaken and the National Parks and Wildlife Service has not yet been consulted. Appropriate studies should be commissioned at the earliest possible time to give an indication of potential issues. • There are a number of potential fauna corridors crossing the highway. The impact of the upgrade on these links and the provision of appropriate means to manage and mitigate the impacts will need to be the subject of detailed studies. • In order to reduce potential adverse impacts on fauna movements, consideration will need to be given to the type of safety barriers to be adopted in the design. If solid barriers are to be adopted to assist in minimising the highway footprint, gaps may be able to be provided. • There may be threatened fish in the rivers, creeks or coastal lakes. Three threatened freshwater fish species have been identified on the North Coast, including Eastern Freshwater Cod, Honey Blue Eye and Oxleyan Pygmy Perch. Early contact should be made with NSW Fisheries to determine issues relating to threatened species under the Fisheries Management Amendment Act. An 8 Part Test will be required. The project will need to address other requirements/issues under the Fisheries Management and Fisheries Management Amendment Acts. • Should the ultimate design for the project require major utility relocations, there may need to be significant additional clearing to cater for the relocated services. Utilities and Services that could potentially be affected include power, water, sewer, telecommunications and rail.


January 2000

Attachment E Agriculture

3

• The majority of the upgrade may be carried out within the existing road reserve, so the impact should be low. • A stand of remnant vegetation exists within the highway road reserve South of Herons Creek. If this stand of remnant vegetation is to be preserved, options which consider a wide median through this area, would also need to take into account the impact on, and acquisition of, additional agricultural land.

Geotechnical Issues

• Construction of embankments over the flood plains will need to be in accordance with best practice for soft soil areas. Widening of existing embankments may have adverse impacts on existing pavements and structures. • There are existing problems within the length of existing highway under consideration due to failure of culverts through embankments constructed on soft soil. Replacement of failed culverts with small bridges may be a feasible option in conjunction with adjacent highway duplication works. • There are a number of hard rock cuttings along the existing highway. Widening of these, if required, will necessitate blasting and will require careful planning and execution.

Contaminated Soils

• Contamination due to current or past uses such as cropping, sawmills, cattle tick dip sites, etc will need assessment. • Mapping from the Department of Land and Water Conservation indicates that there are a number of areas with high or low potential for acid sulphate soils at various locations along the length of the project. Detailed design will need to consider acid sulphate soils. Best practice control measures will need to be put in place during construction. • SMEC Australia conducted an Acid Sulphate Soils study for Hastings Council in the SEPP14 wetland and surrounding area just north of Camden Haven River. The management plan produced by this study, “Rossglen Acid Sulphate Soils - Land Management Plan”, should be reviewed during development of the engineering concept design for the project. • Examination of the EPA’s Contaminated Sites Register should be undertaken during the early stages of full project development, and as part of the formulation and assessment of potential route options.


January 2000

Attachment E Aboriginal Heritage

4

• There do not appear to be any National Parks and Wildlife Service listed sites directly affected by the strategic concept design. Details of the sites indicated west and east of Kew and in the wetland near Camden Haven River, will need to be obtained and confirmed. • The Brother Mountains have spiritual significance for local aboriginal groups. • The area has the potential for scarred trees. The banks of rivers and creeks will need to be carefully examined for middens, campsites, etc. Ridges will also need careful examination. Artefacts are less likely to be found on disturbed areas. • The project crosses the Local Aboriginal Land Council boundaries. South of Kew falls within the Purfleet-Taree LALC and from Kew to Herons Creek is in the Bunyah LALC area. • It is recommended that early and ongoing liaison take place with the Land Councils and that aboriginal archaeological surveys be carried out as early as possible in the project life cycle.

European Heritage

• The heritage status of any affected property needs to be confirmed. No heritage properties listed in the Greater Taree Local Environment Plan appear to be affected. Hastings Council advises that the Royal Hotel on the corner of the highway and Ocean Drive in Kew is heritage listed, as is the Police Station on the old highway. • Consultation with the Heritage Council and other stakeholders will be required.

Waterways and Wetlands

• There are SEPP 14 wetland areas located to the east of the highway around Watson Taylors Lake and on the northern bank of the Camden Haven River (refer to Coastal Wetlands Map in Appendix 1 of this Scope of Work and Technical Criteria). • The road reserve on the western side of the highway opposite the wetland at Camden Haven River is inundated and appears similar in nature to the wetland opposite. The boundaries of the wetland will need to be checked. If it is to be affected, a Part 4 EIS may be necessary. The Department of Urban Affairs and Planning’s draft policy requires that the RTA justifies the selection of any option and the development of any design element which impacts on SEPP 14 wetland. This will need to be addressed early in development of the engineering concept for the project. • The highway along the project length is between five and ten kilometres from the coast. The project crosses two rivers and numerous creeks that empty into the ocean via coastal lakes, Watson Taylors Lake or Queens Lake. • Contact should be made with the EPA to obtain protected/sensitive waters mapping.

Attachment E Erosion and Sedimentation

5

• There are a number of existing cut batters on the project which have eroded. The soil appears to be dispersive. This and other aspects will require comprehensive consideration as part of the geotechnical investigations to be undertaken in developing the engineering concept design. • The provision of sediment basins will require careful design and detailing.

Water Quality

• Mapping from the Department of Land and Water Conservation indicates that there are a number of areas with high or low potential for acid sulphate soils along the project length. Best practice control measures will need to be put in place during design and construction. The RTA should develop an acid sulphate soils management strategy as part of the project’s development and environmental impact assessment. This would, in turn, provide the basis for the development of an Acid Sulphate Soils Management Plan for the project. • Watson Taylors Lake is currently being used for prawning and oyster farming, while Queens Lake is being used for oyster farming. • Base-line water quality monitoring will be required and will need to be commenced as an integral part of project development and environmental impact assessment.

Hydrology & Flooding

• Generally, the project may involve duplication of the existing highway, so impacts should be minimal. The bridge and culvert duplications may be achieved with compatible structures. • Unsubstantiated anecdotal evidence has been provided that flooding of the existing highway has occurred at Stoney Creek, between Passion Creek and Algona Road and between the turnoff to Herons Creek township and Herons Creek. • A full hydrological study of the various waterways will be required in conjunction with the engineering concept design.

Visual

• This is a scenic section of the Pacific Highway. The upgrade needs to sensitively integrate with the landscape and provide the opportunity for road users to view the natural beauty of the area.. • The inclusion of noise barrier walls or noise attenuation mounds may adversely impact the visual amenity of adjacent residents and/or road users. • Project development will need to be carried out in consideration of the principles of urban and regional design.


January 2000

Attachment E Noise

6

• In rural areas, there are only scattered homes along the highway. There may be additional traffic noise impact on some properties. • Within the townships, traffic noise is likely to increase over time with increasing traffic volumes. • A comprehensive base line study will be required with appropriate modelling to predict impacts. • Under the EPA’s “Environmental Criteria for Road Traffic Noise – May 1999”, the work should be classed as a ‘redevelopment of an existing freeway/arterial road’. The work for a bypass at Johns River or at Kew should be classed as a “new freeway or arterial road corridor”. Liaison will be required with RTA’s ECP Branch and the EPA to confirm this. • The inclusion of noise barrier walls or noise attenuation mounds may adversely impact the visual amenity of adjacent residents and/or road users. • Construction noise will need to be controlled by best management practice. Potential mitigation measures for affected locations would be assessed in consultation with the affected residents, the local community as appropriate, and in consideration of cost effectiveness and practicality.

Air Quality

• No significant impact expected. • Control of dust during construction will need to be addressed by best management practice.

LIKELY LEVEL OF ENVIRONMENTAL IMPACT ASSESSMENT REQUIRED: The appropriate level of Environmental Impact Assessment for this project will require further consideration as the development of the project progresses. However, at this early stage, it is believed that the scope and potential impact of the project is beyond that considered appropriate to be treated by a Review of Environmental Factors. Thus, it is likely that an Environmental Impact Statement (EIS) will be required. Significant issues in making the final decision as to the level of EIA may include: • Impacts on Kew and Johns River townships; • Impact on recently declared Yoorigan National Park; • Water quality and impacts on wetlands and coastal waterways; • Threatened flora and fauna species (which may require that a Species Impact Statement be compiled); • Social impact; and • The overall scale of the project.

10/196.1593 AJS PACIFIC HIGHWAY. UPGRADE FROM MOORLAND TO HERONS CREEK. STRATEGIC ESTIMATE. COMMENT ON PEER REVIEW ESTIMATE DETAILS For the purpose of defining the likely range for the Strategic Project Estimate, three (3) option scenarios have been costed. These three option scenarios have been chosen as they are considered to best represent the likely range of feasible route options that will ultimately be presented to the community. The alignment options for these Strategic Estimates include: 1.

Estimate ‘A’ – (Lowest Cost $150M.) - 110km/hour design upgrade along the entire existing highway corridor, with the exception of an 80km/hour design through the townships of Johns River and Kew. Traffic Signals have been allowed at the intersection with Ocean Drive/Kendall Road. Total length 21.9km;

2.

Estimate ‘B’ - (Likely Mid Range Cost $170M.) - 110km/hour design upgrade generally along the existing highway corridor, with an Inner Western Bypass of Johns River and an Inner Western Bypass of Kew. Total length 22.0km; and

3.

Estimate ‘C’ - (Likely Highest Cost $180M.) - 110km/hour design upgrade generally along the existing highway corridor, with an Inner Eastern Bypass of Johns River and an Outer Western Bypass of Kew. Total length 22.5km.

COMPARISON WITH OTHER PROJECTS The estimated cost for this project is low relative to other projects being undertaken under the Pacific Highway Upgrading Program. The following table compares the Upgrade from Moorland to Herons Creek with other Pacific Highway projects. Project No. 66300

Under construction. Minimum work on existing carriageway

Reasons for the relatively low estimated cost for the Upgrade from Moorland to Herons Creek include: (a)

With the exception of the bypass route options which may be required around the townships of Johns River and Kew, the project is expected to retain a large proportion of the existing highway asset. The majority of the proposed highway duplication, is likely to take place primarily along the existing highway corridor.

(b)

At this stage, the proposed lengths of the preliminary bypass route options for Johns River and Kew are relatively short given the overall project length. Therefore the project cost rate per km, is generally low with the range of likely estimated costs, being directly attributed to the various Johns River and Kew bypass route option scenarios.

(c)

Accessibility for construction plant and provision for existing traffic are expected to be straightforward due to the proximity of the existing highway formation.

CONCEPT ESTIMATE

CHAPTER 0

6.1 Summary This chapter sets down the process for preparation of a Concept Estimate.

6.2 Overview There are 3 key stages to the preparation of a Concept Estimate. These are: • Preliminary Project Appreciation Stage; • Estimate Establishment Stage; and • Review and Approval Stage.


It is recommended that an estimate plan be prepared by the Project Manager, to ensure that proper knowledge and resources are available and are applied to preparation of the estimate.

6.3 Preliminary Project Appreciation Stage The following paragraphs indicate the activities that will be undertaken in this interrogative stage:


Concept Estimate Issued December 2001

• • • • • •

6-1

6.3.1 Estimate Programme Approximately 1 week should be allowed for the preparation of a Concept Estimate (assuming that all information is available).

6.3.2 Data Collection The estimator must be provided with all relevant information. This will include: • An understanding of the proposed contracting strategy for the project (for example: design and construct; construct only; single construction contract; multiple contract packages and the like); • A detailed description of the scope of the project. This is an essential component in ensuring the accuracy of the estimate. A sample cost estimate scope is contained in Appendix 6.1; • A complete set of current drawings; • Details of the costs expended on the project to date; and • Any other available information, such as aerial photographs, computer generated quantities, property valuations, hand over cost estimates and the like.

6.3.3 Project Programme A project development programme is to be prepared. This should indicate all significant activities and milestones, together with an approximate construction programme.

6.3.4 Quantities Quantities are likely to be of an approximate nature and will be takenoff by the estimator.

6.3.5 Site Visit A site visit should be made by anyone on the estimating team who is unfamiliar with the project.

Chapter 6



6.3.6 Construction Methods For significant items (such as earthworks or road pavement), the estimator is to determine the probable construction methods that will be adopted by the successful tenderer.

6.3.7 Pre-tender Construction Programme From the methods assumed for significant items and historical productivities, a pre-tender construction programme is established. This will either confirm or replace the preliminary programme established earlier in the process, generally at the Strategic Estimate stage.

6.4 Estimate Establishment Stage This is the stage where the project estimate is actually produced. Before computations commence, the estimator must have regard to RTA’s requirements as to final presentation of the estimate, and the Work Breakdown Structure and Summary required. A sample work breakdown structure is given in Appendix 6.2. The following paragraphs indicate the activities that will be undertaken for a Unit Rates Estimate.

6.4.1 Understanding Historical Data Historical data will be collected and analysed to determine: • Market conditions prevailing at the time of the tender from which the data has been collected; • Any peculiarities of the project from which the data has been collected; • If front-end loading has occurred; and • An approximate allowance for contractors on and off site overheads and profit (if available).



• • • • • •

6-3

6.4.2 Adjusting Historical Data Historical data is to be adjusted to bring it in line with the requirements of the project being estimated, including (if necessary): • • • •

An adjustment for inflation; An adjustment for site conditions; An adjustment for front-end loading; and An adjustment for contractors on and off site overheads and profit.

6.4.3 New Rates New rates are to be computed for significant items (any item worth more than 5% of the total estimate). These may be based on an approximate first-principles estimate, quotations received from suppliers or a detailed assessment of historical data.

6.4.4 Cost Estimate The estimate is calculated by multiplying the quantities by the unit rates deduced from first principles or historical data.

6.4.5 Contractors overheads, risk and margin Generally the contractors overheads, risk and margin is included within the rates adopted earlier and no further adjustment is required. However, if a rate developed from first principles is used, it must have an addition for the contractors overheads, risk and margin.

6.4.6 Project Development Costs Project Development costs are defined in Chapter 4. At the time of preparation of a Concept Estimate, these costs have not all been incurred and may be estimated from past experience.

6.4.7 Detailed Investigation and Design Costs Detailed investigation and design costs are defined in Chapter 4. At the time of preparation of a Concept Estimate, these costs have not been incurred and may be estimated from past experience.

6.4.8 Property Acquisition Costs Property acquisition costs are defined in Chapter 4. Property acquisition costs must be obtained from RTA’s Property Section. Allowances must be made for known property adjustments.

6.4.9 Hand over Costs Hand over costs are defined in Chapter 4. A detailed estimate of these costs is to be prepared.


It is mandatory that a risk analysis be prepared for Concept Cost estimates.

6.4.11 Contingency Contingency is considered in Chapter 3. Appropriate contingencies must be added to each component of the project estimate. At concept estimate stage, contingencies in the range of 20% to 35% are appropriate. Contingencies outside this range must be justified.



• • • • • •

6-5

6.5 Review Prior to commencement of the Concurrence, Approval and Acceptance procedure, the Project Manager should arrange a review of the estimate. This should follow a structured format and be documented.

6.6 Concurrence, Approval and Acceptance All detailed estimates are the subject of concurrence, approval and acceptance as detailed in Chapter 2. The procedure is detailed in the following flowcharts.

INTRODUCTION

This report outlines the works included in the cost estimate for the preferred alignment option known as the Gosport Street Option (Option 2 in earlier studies). The option has evolved from consideration of seven feasible route corridors (4 inner and 3 outer) to the scheme currently on public display, see Figure 1.1 for the alignment in relation to Moree. The preferred alignment option has been sufficiently developed to show the general form of the bypass, treatments at key locations (intersections, access links, railway station precinct and the like) and properties affected by acquisition. The cost estimate for the Bypass has been derived from a schedule of main construction activities and typical unit cost rates as well as a contingency allowance to deal with the normal unknowns and variations that inevitably arise. The desirable outcome is that this Initial Concept Estimate will not be exceeded by the Final Concept Estimate and later on the Detailed Estimate as the design evolves. This document is to be read in conjunction with the attached cost estimate spreadsheets.

THE PROJECT

The cost estimate presented is for the preferred alignment option with Tee intersections at the two Newell Highway connections, see Figures 1.2 and 1.3 attached for details of the Initial Concept Design. This estimate is referred to as the ‘base case’ estimate. As an aid for comparison of this project estimate with that of other similar road projects, separate estimates have been established for the three environmentally distinct sections that can be found along the route. The three distinct sections are: !

Urban Section South •

!

Urban Section North •

!

This section extends from the Newell Highway to the Spa Baths (CH 00 to CH1020) and comprises a complete upgrade at the highway (Tee intersection) and reconstruction of the two central lanes in existing Gosport Street. The environment through which the route passes is built and essentially industrial/commercial in nature with residences (12) interspersed throughout

Travelling north from the Spa Baths the bypass deviates from existing Gosport Street and travels beside the railway to the Mehi River (CH 1020 to CH 1920). The construction within this section is for the full carriageway width and includes a combined road/rail signalised intersection upgrade at the Gwydir Highway. In relation to built environment the section is predominantly urban with the rural interface at the river.

Rural Section North •

Continuing north via a new bridge over the Mehi River the Bypass follows Gwydirfield Road and a lane at the rear of the Moree racecourse before connecting onto the existing Newell Highway (Tee intersection) (Ch 1920 to Ch 3760). The surrounding environment is rural with small hobby style farms along the eastern side. Council has indicated that they are favourably considering re-subdividing these rural holdings into smaller lots (2 to 2.5 hectares in size).

The public display also shows alternate high-speed intersection treatments at the two Newell Highway connections with the alignment biased towards the Bypass, see Figures 1.4 and 1.5. The cost estimates for these two sub-options have been separately determined.

2.1

BYPASS DESIGN PHILOSOPHY

In the southern Gosport Street section a ‘best fit’ approach has been adopted as the most appropriate. Local deviations in level and pavement shape have been smoothed to achieve a geometric standard suitable for a national highway. The design speed within this urban section changes from 100km/h at the Mehi River to 70km/h speed prior to the Gwydir Highway. The latter speed being considered compatible for an arterial road within an industrial urban environment.


Printed: 4 May 2001


The status of the concept design at this stage is preliminary and detailed features such as water quality ponds or widening for say guardrail flaring has not been incorporated into the design model. While still to be finalised, the pavement adopted as most appropriate for both the urban and rural sections is a heavy duty semi-rigid pavement comprising an AC wearing course and deep lift asphalt base over a lean mix subbase and select material zone. This pavement type was considered best to manage the notorious expansive black clay subgrade and volume of heavy traffic (currently predicted at some 1200 semi-trailers/road trains per day). In the urban section the pavement extends to either just beyond the edge of the through traffic lane (traffic lane plus 300mm) or if in a kerbed area across the full road (traffic lanes and adjacent parking lane). In the rural area the pavement extends across the full carriageway width (traffic lane and shoulder). In relation to flooding and highway operation the initial concept has been designed to be trafficable during a 1 in 20 year recurrent flood event, that is one lane in each direction flood free. In larger events, ie.1 in 100 year ARI, the Bypass would be inundated and most likely closed to traffic. This flood free standard is consistent with performance goals for the national highway system.

BASE CASE ESTIMATE DETAILS

3.1

GENERAL

Property acquisition The cost of property acquisition in this initial estimate is based upon anticipated just compensation that makes allowance for the value of holding and a solartium/relocation provision. The RTA are at present undertaking valuation assessments and having discussions with affected property owners. As details come to hand the cost estimate will be accordingly updated. Indications to date suggest that the overall estimate for acquisition is of the right order. Where railway property is to be acquired the stated position of Rail Access Corporation is that the whole of the property on the roadside and beyond is to be acquired. For instance, in the case of the former railway siding to the Morton Street Woolstore (north of the Bypass) will have to be acquired, as will the tennis court property west of the Bypass. In this project it is likely that the RTA will become an owner of residual property that may not be able to be on-sold. Where on selling is possible the credit benefits have been accrued to the project. Construction mobilisation and operation In the estimate the cost of mobilisation, establishment, community liaison and preparation of 15 project plans (management plans - environmental, earthworks, traffic, OH&S, QA, etc) has been allowed. The estimate includes a provision for general items such as for preparation of: •

Contract required plans (eg. Project Quality Plan, OH&S Plan, Environmental Management Plan, etc),

•

Traffic management

•

monitoring noise, vibration, air and water quality, vegetation protection

•

heritage and fauna surveys

•

Two building condition inspections (before and after) have been allowed at each frontage site including 25 properties in Morton Street that are within 90 metres of the bypass (within the noise impact zone).

•

Demolition of unwanted works

The cost has been uniformly distributed over the three road sections (urban south, urban north and rural north) Earthworks South of the Gwydir Highway the Bypass has been graded to match the existing surface. Earthworks for this urban section have been calculated from the product of pavement area by the depth of pavement (including the SMZ zone) less an allowance for salvaged pavements and topsoil stripping. North of the Gwydir Highway the earthworks have been Rev: B S:\20000 series\20299\RTA Samples\Moree\Cost Estimate Scoping Report.DOC

Printed: 4 May 2001


determined direct from the concept design model with an additional allowance for creek works and the highway intersection upgrade. In respect of the earthworks the following general assumptions have been made: •

A stripping depth of 100mm for salvaged pavements. The existing pavements in the area are known to be thin.

•

A topsoil stripping depth of 100mm

•

A compaction factor of 10%.

In summary the earthworks cut/fill volumes for the base case are:

Construction period and sequence A construction period of 18 months is envisaged. The construction sequence for the project presumes that the Mehi River bridge and the inner urban sections within the town would be undertaken first and any excavated material that is surplus to requirements disposed of during this first stage. Early completion of the bridge would provide a cross-river connection and reduce construction traffic impacts on surrounding Moree. Pavement The pavement proposed for the urban and rural sections is a heavy duty semi-rigid pavement comprising: •

a 50mm AC 14 wearing course,

•

a 150 mm deep lift AC 20 base course over

•

a 175mm lean mix sub base, and overlaying

•

a 300mm SMZ layer

The Select Material Zone is to be made up of salvaged road base obtained from existing roads and gravel from the gravel pits off the Newell Highway 10 km north of Moree. Rev: B S:\20000 series\20299\RTA Samples\Moree\Cost Estimate Scoping Report.DOC

Printed: 4 May 2001


The AC is likely to be batched on site with material imported by road. The AC quantities used in the estimate have been derived from the product of the pavement surface area and thickness and then converted to tonnes (2.35 tonnes per m3). The lean mix quantities have been based on the AC quantity and converted to m3 and adjusted for the extension beneath kerbs. Drainage In the urban section north of the Spa Baths the bypass is kerbed and an underground drainage system provided, see Figure 1.6 for the layout. The system has been design for one lane to flood free during a 1 in 20 year recurrent storm event and a maximum intrusion distance of water into the travel lane of 1.0m. In the urban section south of the Spa Baths, other than at the Newell Highway intersection upgrade, the works are confined to upgrading the central traffic lanes only and use is made of the existing Gosport drainage system. Noise The EIS working paper on noise and noise impacts is in the process of being finalised. Thus in relation to this estimate the extent of work and costs assumed for the mitigation measures while indicative is embracive of a number of feasible solutions. The cost presently allowed in the estimate for full mitigation treatment of a residence (thick glazing, sealing of doors and roof, air conditioning) is $15,000 and thick glazing of a residence or factory office $2,000.

3.2

URBAN SECTION SOUTH - NEWELL HIGHWAY (SOUTH) TO THE SPA BATHS

3.2.1

Extent of Work

At the southern end of the project the limit of work for the base case is located immediately north of the existing Amaroo Drive intersection. Improvement works shown further south (including the adjacent Amaroo Drive connection) are part of a Bulluss Drive upgrade project, a separate works project. The scope of work for this section includes: •

Construction of a Tee intersection at Gosport Street/Newell Highway connection - existing pavement reconstruction on both the Newell Highway and Gosport Street, upgrading of the intersection and immediate area stormwater/drainage system, construction of a water quality/spillage control pond, intersection street lighting and urban design/landscaping. Partial property acquisition is involved to accommodate the upgraded intersection.

•

Gosport Street between the Newell Highway intersection works and Jones Avenue - full reconstruction of the two central traffic lanes only, the reconstruction extending 300mm beyond the outside edge of the travel lane. Enhancement of infrastructure works beyond, other than match to existing, that is, upgrade of existing shoulders, footpaths, kerbs, driveways, drainage, utility services and street lighting is not included in this base case estimate.


Printed: 4 May 2001


•

3.2.2

Gosport Street between Jones Avenue and the Spa Baths - as well as full reconstruction of the two centre traffic lanes the inclusion of a common centre turn lane (pavement reconstruction similarly to extend 300mm beyond the outer edge of the travel lane). Except for relocation of a watermain on the western side of the new pavement work and possible level adjustments to several sewer manholes, no upgrade to the existing infrastructure facilities beyond is envisaged.

Constraints

The priority at the Newell Highway intersection has been designed to favour the Bypass with southbound Frome Street traffic (former Newell Highway) required to give way to right turning Bypass bound traffic (northbound). To ensure ease of movement this right turn is to be superelevated. Other than at the Newell Highway intersection where some partial property acquisition is required, the new work along Gosport Street fits within the existing road reserve. In this section there are 16 industrial/commercial facilities and 12 residences fronting Gosport Street. Provision has been made in the estimate for temporary vehicle access to these properties. Gosport Street to be constructed one half road at a time. At the Newell Highway intersection the new work on the Gosport Street approach is generally clear of the existing carriageway thereby simplifying construction. To maintain north-south traffic flow along Frome Street (former Newell Highway) a sidetrack is required, vacant TSR land to the west is available.

3.2.3

Cross Section

Both the through and turn lanes are 3.5m wide with local widening at the Newell Highway intersection to enable road trains up to 35m long to turn. Road shoulders where shown are 2.0m wide.

3.2.4

Road Geometry

This southern urban section is in a built environment and accordingly the Bypass has been designed for a low speed (70km/h design). ‘S’ bends within the section assist in reinforcing the low speed message to drivers.

3.2.5

Intersection and Local Roads

At the Newell Highway intersection the median and splitter islands are to be kerbed and street lighting installed. Along Gosport Street the side road connections (Jones Avenue, Thompson Avenue, and Adelaide Street) are graded to smoothly join the new work, the limit of which is generally in line with the Gosport Street boundary.

3.2.6

Earthworks

Of the 8300 m3 of cut material obtained from this urban section some 2100 m3 is estimated to be surplus to the overall project requirement and to be disposed off. The remainder is to be transported direct to the embankment south of the Mehi River. The material excavated in this section is likely to a mix of black clays and gravel/sand road base.


Printed: 4 May 2001


3.2.7

Pavement

Fluctuations in heavy vehicle traffic arising from Moree’s seasonal wheat and cotton activities are difficult to predict and can vary considerably throughout the year. The close proximity of the Bulluss Drive (a primary east/west access to Moree’s industrial area and wheat silos) to the Bypass/Newell Highway intersection is an added complication that requires a flexibility of design. To accommodate the possibility of heavy vehicles standing on Gosport Street provision has been made in the estimate for the full pavement depth to extend into the approach road shoulder for a distance of 140m (to Ch260).

3.2.8

Drainage

At the Newell Highway intersection the road surface is slightly higher than the general surrounds. This is an inherited condition. To ensure drainage of the immediate area a system of shallow table drains and pipes are proposed. This new system will divert the runoff collected into a water quality/spillage control basin located in acquired TSR land west of the existing highway. North of the highway intersection (Newell Highway intersection to Spa Baths) the Bypass utilises the existing Gosport Street drainage system. There is no provision in the base case estimate for upgrading existing drainage facilities in this area.

3.2.9

Structures

No major structures occur within this section.

3.2.10

Property Adjustments and Acquisitions

At the Newell Highway intersection and at the connecting side roads (Jones Avenue, Thompsons Avenue and Adelaide Street) partial acquisition of several properties is required to accommodate the new intersection or address road safety concerns by improving driver sight lines. Properties where acquisition is envisaged are: Newell Highway •

An existing building on Lot 10 DP 37950 Peter & Sandra Duncan prevents a corner splay on the north side of Adelaide Street from being acquired.

3.2.11

Public Utility Adjustments

There are a number of public utility services, particularly at the southern end of the project, which are impacted on by the new works. While the requirements of the relevant authorities are to be finalised provision has been made in the estimate for: •

Protection and relocation of Telstra services (a nominal allowance)

•

Relocation of 3 low voltage and 11 high voltage power poles impacted on by the intersection works

Between the Newell Highway intersection and the Spa Baths: •

Minor adjustments to several sewer manholes in the area and an allowance for possible protection of 60 metres of sewer main.

•

Relocation of 470 metres of 150mm watermain

•

Adjustments to watermain fixtures at the Newell Highway intersection

•

Relocation of water supply house connections to eight frontage properties in Gosport Street

3.2.12

Noise Mitigation

Mitigation measures envisaged within this section are: •

Installation of thick window glazing at 21 individual factory offices,

•

Installation of thick window glazing, sealing of doors and roofs and possible installation of air conditioning at 12 residences.

3.2.13

Urban Design

While the urban design requirement for this project is to be resolved a provisional sum of $129,950 has been made in the estimate for an entry statement at the southern intersection.

3.2.14

Miscellaneous

Street lighting of the Newell highway intersection is included in the concept design. There is no provision for lighting the midblock section of Gosport Street. The estimate has been based on 8 poles along each approach and cabling supply to the site. Property adjustments works in the area are minor and involve relocation of driveways, gates and fences.

3.2.15

Handover

At the completion of the Bypass the Frome Street south section of the former national highway is to be upgraded for handover to Council. The upgrading extends to patch repair and resealing of from the Gwydir Highway (Alice Street) to Gosport Street.

3.3

URBAN SECTION NORTH – JONES AVENUE TO MEHI RIVER (Ch 1020 to Ch 1920)

3.3.1

Extent of work

The extent of work within this urban north section includes:

3.3.2

•

Between the Spa Baths and the Gwydir Highway the bypass deviates through railway land. The Bypass is new and fully kerbed with two through traffic lanes and parking lanes either side. Stormwater drainage is provided and piped to a detention basin located in acquired land north of the Gwydir Highway.

•

The Gwydir Highway intersection is signalised and integrated with the adjacent rail crossing. Each road approach (highway and bypass) comprises a sheltered right turn lane, a through traffic lane and a shared through/left turn lane.

•

In the section between the Gwydir Highway and the Mehi River the bypass transitions from an urban profile to a rural one at the bridge. The rural section comprises two through lanes and shoulders either side. The stormwater detention basin mentioned previously is located on acquired land east of the Bypass (between the Bypass and Gosport Street) and is used to control runoff, water quality and spillage.

•

Enhancement of railway/Spa Baths precinct. The precise nature work in this area involves a number of stakeholders (Rail Infrastructure Corporation, Rail Services Australia, Council,). While the precise requirements of stakeholders is to be established the provision in this base case estimate includes : -

Roadworks at the Gosport Street / Anne Street intersection,

-

Removal of the tennis courts,

-

Relocation of the railway workshops (to the tennis court site),

-

Relocation of the railway carpark and bus setdown to Morton Street (eastern side of the station), and

-

Provision for a featured landscaped reserve opposite the Spa Baths

•

A modified road link between River and Morton Streets at the Showground.

•

Provision of a narrow road connection between Morton Street east (north of the Gwydir Highway) and Oak Lane.

Constraints

The Bypass at Gwydir Highway intersection is aligned as close to the railway line as can be practically achieved (10m offset from track centreline to Bypass boundary). The close proximity of the two facilities enables an efficient and safe integration of the Gwydir Highway/rail crossing to be achieved. The cost for providing an integrated signalised system includes a contribution to the railways for upgrading the rail signalling.


Printed: 4 May 2001


The total cost of the traffic signals including contingencies is estimated at $523,500 (road signals $336,000 and railway signals $188,500).

3.3.3

Cross Section

Through and intersection turn lanes are 3.5m wide with local widening to cater for the turn path of road trains up to 35m long.

3.3.4

Road Geometry

The geometry of this southern urban section is mostly dictated by aligning the road and rail in a common transport corridor. In the transition zone between urban and rural (north of the Gwydir Highway) the road is curved and the carriageway superelevated to safely manage the higher travel speed.

3.3.5

Intersection and Local Works

At the Gwydir Highway intersection provision has been made in the estimate for reconstruction of the existing highway between Gosport and Morton Streets. Further provision has also been made for relocation of the railway carpark to the eastern side of the station and relocation of affected railway workshops to the tennis court area. Roadwork improvements at Gosport Street/Anne Street, River Street/Morton Street and Morton Street/ Oaks Lane connections.

3.3.6

Earthworks

The Initial Design Concept model indicates some 12550 m3 of fill material is required for the embankment on the southern side of the Mehi River. Excavations from both urban sections yield sufficient material to meet this need. The average haulage distance involved is one kilometre (maximum two kilometres).

3.3.7

Pavement

The full pavement within this section extends across the whole carriageway including travel/turn lanes and shoulder/parking lanes.

3.3.8

Drainage

In this section the Bypass is for the most part fully kerbed and a piped drainage system is provided to collect and direct runoff to the Mehi River via a detention basin (located on the acquired land between River Street and the Gwydir Highway). The system is separate to the existing Council system in Gosport Street. Water surface levels in the Mehi River (available head) and the time it takes for the river to lower after flooding determines the need for a detention basin and controls where the discharge point can be (western side of the Bypass where the river level is lowest). Historically the water level in the Mehi takes two to three days to lower when the river has been in flood. A water quality/spillage control pond is proposed at the upstream side of the detention basin. For safety reasons this pond is to be fully fenced. The design criteria applied to the detention basin (water depth 1.0m max., embankment slopes 1 in 6) enable the area to be open to the public and used as park or play ground.


Printed: 4 May 2001


An assumption in the design is that the railway land in the station precinct (east of the Bypass) can be drained to the existing Anne Street outlet by installing shallow table drains and modifying the existing pipework. The table drains are shown located within railway property. Existing drainage lines in Morton Street enable the relocated railway carpark to be readily drained.

3.3.9

Structures

No major structures occur within this section.

3.3.10

3.3.11


Other than disconnection of services to the acquired properties listed above, the known public utilities where works are required are: •

Diversion of a 150mm sewer main between Gwydir Highway and Morton Street north. This main is the discharge line for a rising main from the Services Club in Albert Street.

•

Relocation of Telstra services in Gwydir Highway

•

Relocation of several power/light poles currently in railway property

3.3.12

Noise Mitigation

The noise impacts within this section where noise mitigation measures are provided in this estimated include: •

Installation of thick window glazing in 28 residences at $2,000 each,

•

Installation of thick window glazing, sealing of doors and roofs and possible installation of air conditioning to 6 residences at $15,000 each.

•

Treatment at the Spa Baths to the value of $15,000

•

Treatment at the Victoria Hotel to the value of $30,000

•

Treatment at the Motel (cnr Gosport St & Gwydir Hwy) to the value of $15,000

•

Treatment at the hotel (cnr Gwydir Hwy & Morton Street) to the value of $15,000

•

Installation of a noise wall along the western side of the Bypass north of the Gwydir Highway to protect the Gosport Street, River Street residents, the showground caretaker and Mrs Samson’s house if relocated to Morton Street. The wall is 1.8m high, 360m long and sited on top of an earth mound. Further analysis of noise impacts on the Gosport Street and River Street residences may lead to treating individual houses rather than the installation of a wall. The estimate will be refined as details become available.

3.3.13

Vibration Mitigation

The assessment report indicates that vibration problems are not anticipated and that no special treatment is required at the Spa Baths.

3.3.14

Urban Design

Special urban design/landscaping features for this project are yet to be established and a provisional sum of $258,600 (including contingencies) has been allowed in the estimate for treatment of the Spa Baths/tennis court precinct, the detention basin in Gosport Street, relocated railway carpark, and local road connections.

3.3.15

Miscellaneous

The former railway booking office located between the Bypass and the railway station is to be demolished. Other than Mrs Samson’s house structures on the acquired properties are to be demolished. No provision has been made in the estimate for any salvage value. An allowance has been made in the estimate for street lighting the Gwydir Highway intersection.

3.4

RURAL SECTION NORTH – MEHI RIVER TO NEWELL HIGHWAY (NORTH) (Ch 1920 to Ch 3760)

3.4.1

•

At the Mehi River crossing, a 150 metre two-lane bridge. The bridge is to minimum width in accordance with current standards (2 x 3.5m traffic lanes, 1.2m wide shoulders either side). There is no provision for a footway.

•

Two lane two way rural road with paved shoulders (Mehi River to the Newell Highway)

•

Tee intersection at the Newell Highway.

•

Connection of Gwydirfield Road onto the Bypass and closure of the Webb Avenue link (south of the Racecourse)

•

Major culvert crossings at Stringers Creek and two channels

Constraints

The priority at the Newell Highway intersection is designed to favour the existing highway. Drivers heading north on the Bypass are required to give way. As previously stated the design philosophy for this rural section does not differ basically from that of any other two lane rural highway. However, the emphasis to satisfy the physical constraints (sight lines at the Newell Highway intersection, minimising property acquisition), and the environmental constraints (clearance between railway and Bypass bridges, containment of the impact on the river corridor) dictates an alignment designed for 100km/h rather than 110km/h. There are 7 rural properties including heritage listed “Gwydirfield” homestead that front the Bypass. Provision has been made in the estimate for access.


Printed: 4 May 2001


3.4.2

Cross Section

The traffic and turn lanes are 3.5m wide (with local widening at intersections to allow for the turn path of road trains up to 35m long) and the road shoulders 2.0m wide.

3.4.3

Road Geometry

As stated above the geometry in this rural section is designed to a 100km/h design standard.

3.4.4

Intersection and Local Roads

At the Newell Highway intersection the median and splitter islands on the Bypass approach and are to be kerbed. Street lighting is also to be installed to improve intersection visibility and safety. The Gwyderfield Road connection is to a rural country road standard. A 3.7m low height clearance on the adjacent railway bridge limits vehicle usage. A cul-de-sac style closure of Webb Avenue is envisaged.

3.4.5

Earthworks

The cut to fill within this section is in balance with some 16550 m3 cut material obtained from the excavation works.

3.4.6

Pavement

As previously stated the pavement for both travel lanes and shoulders is a deep lift semirigid heavy-duty pavement designed to best manage the expansive black clays.

3.4.7

Drainage

In this area the Bypass crosses the Gwydirfield flood plain and the road set for the travel lane to be flood free during a 1 in 20 year flood event. Water sheds to table drains on either side of the bypass. The EIS flood study has established the size of the bridge and culvert openings.

3.4.8

Structures

The major structures within this section are: •

150 m long bridge over the Mehi river (2x3.5m traffic lanes with 1.2m shoulders either side)

•

A 4 cell 1.2 x 2.4 RCBC at each of the two channel crossings

•

.A 17 cell 1.2 x 2.4 RCBC at Stringers Creek

Mehi River Bridge The flood study has confirmed that a 150m long bridge is adequate without major afflux impacts. The estimate allows for increasing the design loading from HLP320 to a SM1600 standard. The contingency allowance includes provision for a possible increase in shoulder width from the designed 1.2m to 2.0m.


Printed: 4 May 2001


Major culverts A Box culvert arrangement at the channel and creek crossings has been adopted because of the limited height available between the invert and road level.

3.4.9


Property acquisition is required within this section: Gwydirfield Road •

Aboriginal heritage steel bridge camp site At the Mehi River the Bypass traverses the aboriginal heritage “Steel Bridge” camp site. Costs if any have not been determined at this stage and the RTA negotiations with the aboriginal community are continuing. Property resale credits Unless discussions with the landowners indicates otherwise the properties listed below are assumed as being purchase as a whole and the residual available for resale. Resale properties: •

Hifields Lot 3 DP 540123 - rural property

•

Long lands Lot 1 DP 535838 - rural property

3.4.10


The known utilities in this rural section where provision in the estimate has been made are: •

A relocation of Telstra service

•

Relocation of 6 power poles

At the Newell Highway intersection: •

Protection of existing water mains in the vicinity of the water supply pump station.

3.4.11

Noise Mitigation

Noise mitigating is required at Gwydirfield homestead.


Printed: 4 May 2001


3.4.12

Flood Mitigation

A flood study undertaken as part of the EIS working papers indicates that there will be an afflux increase in water level during river flooding as a result of the bypass and that flood mitigation is required at the “Gwydirfield” homestead (80mm afflux during 1 in 100 year ARI). Provision has been made in the estimate for installing a small bund wall around the homestead.

3.4.13

Urban Design and Landscaping

The special urban design features for this project are yet to be established and a provisional sum of $84,540 has been made in the estimate for an entry statement at the northern intersection and for a display feature at the Steel Bridge Camp site. Landscaping is required at the racecourse to shield the course from headlight glare, an issue during early morning training. A provision of $52,000 has been allowed in the estimate.

3.4.14

Miscellaneous

In this section it has been assumed that a fence is required along the acquired property boundary. No provision has been made in the estimate for fencing the western side between the Mehi River and the Bypass. Safety barriers (protective steel guard fence) are envisaged on the approaches to the bridge (200m long) and at the culvert crossings (100m long at the two channels and 150m long at Stringers Creek).

P Standen Project Manager 01 March 2001 R.O Ref: 17/291.1161

STATE HIGHWAY NO 17 - NEWELL HIGHWAY. PROPOSED MOREE BYPASS. SUBMISSION FOR CONCURRENCE WITH THE DRAFT INITIAL CONCEPT ESTIMATE.

PURPOSE The purpose of this submission is to gain concurrence to the Draft Initial Concept Estimate for the subject project. BACKGROUND The preferred option (ie the Gosport Street Option) was approved by the Federal Minister for Transport & Regional Services on 14 June 2000. The announced project estimate was $27M. (Concurrence to the Preliminary Estimate for the Preferred Option was granted by PMO on 13/3/00). Following initial concept design development work, a meeting was held on 7/11/00 between Western Region Client Services, RNI and DoTRS to facilitate presentation and discussion of the preliminary concept design for the project. At this meeting, RNI and DoTRS were advised that the Initial Concept Estimate was likely to exceed the approved Preliminary Estimate by up to ten per cent. Furthermore, there are a number of scope issues associated with the intersection treatments at each end of the project that need to be agreed and finalised. It was agreed that the Project Manager would prepare a Scope Report and an associated Draft Initial Concept Estimate for the current scope of works along with costings of the various potential scope changes with regard to the bypass connections. Further discussions would then be held to finalise the scope of work and to discuss funding implications. RNI requested that the Draft Initial Concept Estimate be submitted to PMO for concurrence prior to the proposed further discussions.

The estimate now submitted for PMO concurrence is the Draft Initial Concept Estimate as described above. Following concurrence and approval of the Draft Initial Concept Estimate and agreement with DoTRS with regard to the scope of the project, the estimate will be adjusted accordingly and re-submitted for concurrence as the Initial Concept Estimate. SCOPE CHANGES In addition to the Draft Initial Concept for the project, PMO is also requested to review the estimates for the potential scope changes for the project (as discussed Andrew/Standen on 1/3/01). These scope changes comprise: 1. 2. 3. 4.

High speed connection at northern end High speed connection at southern end Extension of project at southern end (Bullus Drive/Amaroo Drive Upgrade) Full width construction (4 lanes instead of 2) in southern rural section

Estimate and design details of these scope changes are currently being finalised and will be forwarded by 9 March 2001. ATTACHMENTS The following documents are attached: 1. Estimate Concurrence - Verification Checklist 2. Preparation of Concept Estimate - Verification Checklist 3. Estimate and Scoping Report The “Estimate Approval & Acceptance Form” will be forwarded following completion of the peer review for the estimate. RECOMMENDATION It is recommended that concurrence be granted to the Draft Initial Concept Estimate in the amount of $28.85M.

DETAILED ESTIMATE

CHAPTER0

7.1 Summary This chapter sets down the process for preparataion of a Detailed Estimate.

7.2 Overview There are 4 key stages to the preparation of a Detailed Estimate. these are: • • • •

Preliminary Stage (or Interrogative Stage); Project Appreciation Stage; Estimate Establishment Stage; and Review and Approval Stage.


It is recommended that an estimate plan be prepared by the Project Manager, to ensure that proper knowledge and resources are available and applied to the preparation of the estimate.

7.3 Preliminary Stage The following flow diagram indicates the activities that will be undertaken in this interrogative stage: RTA Project Estimating Edition 1, Revision 0

7.3.1 Estimate Programme This activity is essential to the success of the preparation of the estimate. Approximately 2 weeks should be allowed for the preparation of a Detailed Estimate (assuming that all information is avaialble).

7.3.2 Data Collection The estimator must be provided with all relevant information. This will include: • An understanding of the proposed contracting strategy for the project (for example: design and construct; construct only; single construction contract; multiple contract packages and the like); • A detailed description of the scope of the project. This is an essential component in ensuring the accuracy of the estimate. A sample cost estimate scope is contained in Appendix 7.1;

7-2

• • • • • •

Chapter 7



• A complete set of current drawings; • Details of the costs expended on the project to date; and • Any other available information, such as aerial photographs, computer generated quantities, property valuations, handover cost estimates and the like.

7.3.3 Project Programme A project devlopment programme is to be prepared. This should indicate all significant activities and milestones, together with an approximate construction programme.

7.3.4 Significant Components The estimator will be aware of likely significant components within the project estimate (for example, on a road project the concrete or asphalt sub-base and base; on a bridge project reinforcement and structural concrete). The estimator may seek quotations (verbally or in writing) from local suppliers or subcontractors for these components. Written quotations should be kept in the estimate files; verbal quotations should be recorded (a convenient form for recording verbal quotations is included in Appendix 7.2).

7.3.5 Quantities Quantities are either provided in computer generated form, direct from the design, or taken-off by the estimator. Where quantities are provided by computer aided design packages, care must be taken that the program is actually producing the correct output. Problems have been discovered in the past where (for example): • earthworks quantities have been generated assuming a flat horizontal surface plane where a dual carriageway is at split level; • earthworks quantities have been generated without allowance for topsoil; • fill quantities have been incorrect, without allowance for the reduction in fill due to the road pavement; and



• • • 7-3 • • •

• pavement quantities have been incorrect, as the wrong centreline for the superficial area calculation has been wrong.

7.4 Project Appreciation Stage The following diagram indicates the activities that will be undertaken in this project appreciation stage:

7.4.1 Site Visit A site visit should be made by anyone on the estimating team who is unfamiliar with the project. Appendix 7.3 gives a checklist of the significant items to be considered.

7.4.2 Construction Methods For significant items (such as earthworks or road pavement), the estimator is to determine the probable construction methods that will

7-4

• • • • • •

Chapter 7



be adopted by the successful tenderer, together with the likely plant.. For example, in a roadworks project, will the earthworks be by scraper or dozer and truck?

7.4.3 Pre-tender Construction Programme From the methods assumed for significant items and historical productivities, a pre-tender construction programme is established. This will confirm the preliminary programme established earlier in the process.

7.5 Estimate Establishment Stage This is the stage where the project estimate is actually produced. Before computations commence, the estimator must have regard to RTA’s requirements as to final presentation of the estimate, and the Work Breakdown Structure and Summary required. A sample work breakdown structure is given in Appendix 7.4. The following diagram indicates the activities that will be iundertaken for any item that is to be estimated from first principles:

7.5.4 Built-Up Unit Rates At this stage, a number of built-up unit rates will have been calculated. It is often helpful in later reviews and investigations if a common format and calculation be used for establishing first principles rates. The estimate establishment stage continues as shown in the following diagram:

7.5.5 Direct Cost Estimate The direct cost estimate is calculated, by multiplying the quantities by direct cost rates. The rates used may be (for significant items) those calculated earlier in the process of preparation of the estimate, or deduced from historical data.



• • • 7-7 • • •

7.5.6 Indirect Cost Estimate Reference to the pre-tender construction programme will establish the likely duration of the construction activities. This may then be used to calculate the indirect costs. Items to be considered (where not in the direct cost) include: • Site management salaries and allowances (travel, accommodation, superannuation); • Temporary facilities (offices, sheds, utilities, communications); • Labour not included within the direct cost (attendant labour, surveyors); • Plant not included within the direct cost (float to and from site, scaffolding); • Consumable tools and equipment; • Finance charges, legal fees, insurances & excesses, security bonds.

Special attention should be paid to certain items, to ensure adequate allowance is made for: • Design fees and other consultant costs (in the case of a design and construct delivery mechanism); and • The contractors allowance for non-recoverable escalation (dependent upon the commercial delivery strategy).

7.5.7 Contractors overheads, risk and margin To the sum of the indirect cost and the direct cost (“cost”) must be added the contractors overheads, risk and margin. Overheads refers to the contractors home office (corporate) overheads. In the absence of any other data, 5% of the cost should be allowed. Risk refers to the contractors allowance for its perceived net risk (after consideration of all risks and opportunities) in the project.

7-8

• • • • • •

Chapter 7



Depending on the commercial strategy of the project, risks and opportunities may include: • • • • • •

Design risk; Quantities risk; Rates risk; Errors & omissions risk; Market risk; etc.

In the absence of any other data, an amount in the range of 3% (schedule of rates delivery method) to 10% (design & cosntruct delivery method) of the cost should be allowed. Profit is the amount that the contractor anticipates it will make in profit after all costs have been paid. In the absence of any other data, an amount in the range of 3% (competitive market) to 5% of the cost should be allowed.

7.5.8 Project Development Costs Project Devlopment costs are defined in Chapter 4. At the time of preparation of a Detailed Estimate, these costs have probably been incurred and may be determined from the project ledger.

7.5.9 Detailed Investigation and Design Costs Detailed investigation and Design Costs are defined in Chapter 4. At the time of preparation of a Detailed Estimate, these costs have mostly been incurred and may be determined from the project ledger. However, allowance must be made for the remaining costs.

7.5.10 Property Acquistion Costs Property acquisition costs are defined in Chapter 4. Property acquisition costs must be obtained from RTA’s Property Section.



• • • 7-9 • • •

Allowances must be made for known property adjustments.

7.5.11 Handover Costs Handover costs are defined in Chapter 4. A detailed estimate of these costs is to be prepared.


It is mandatory that a risk analysis be prepared for detailed cost estimates.

7.5.13 Contingency Contingency is considered in Chapter 3. Appropriate contingencies must be added to each component of the project estimate. At detailed estimate stage, contingencies in the range of 10% to 20% are appropriate. Contingencies outside this range must be justified.

7.6 Review Prior to commencement of the Concurrence, Approval and Acceptance procedure, the Project Manager should arrrange a review of the estimate. This should follow a structured format and be documented. A sample estimate review sheet is attached at Appendix 7.5.

Limits of Work The work extends from the Old Windsor Road / Sunnyholt Road intersection and extends northwards along Old Windsor Road and then Windsor Road to 300m north of the intersection of Windsor Road and Merriville Road. Length: 2,700m. The work is shown on the Concept Design Plan attached in Appendix B. Design Drawings Concept Drawing No.0635.040.CD.0001 (attached to the REF) Detail Design Drawing 0635.040.RC.2501 (Sunnyholt Road to Caddies Creek) * Note: Detail Design of the next section from Caddies Creek to north of Merriville Road is not yet complete.

Page 1

Type of Construction Reconstruction and widening on a new and existing alignment, with the Old Windsor Road portion being on new alignment slightly to west of existing and the Windsor Road portion being widened on the existing Windsor Road alignment. Cross Section & Design Divided carriageway with two 3.25m wide lanes in each direction along Old Windsor Road and then three 3.25m wide lanes in each direction from 200m south of the Old Windsor Road / Windsor Road intersection to the northern limit of the work. A shoulder, 1.5m wide is provided on each carriageway on Old Windsor Road plus a 1.5m verge in fill areas or a 1.0m SO gutter in cut areas. Median width is 4.5m minimum up to 9.0m. On Windsor Road a 1.5m shoulder has been allowed in the southbound direction along with 0.7m wide SA kerb and gutter on both sides. Turn lanes of 3.0m are provided at the Samantha Riley Drive, Windsor Road and Merriville Road intersections. Provision for double right turns is incorporated at all intersections plus a double left turn out of Samantha Riley Drive (east) into Old Windsor Road (south) and Windsor Road (south) into Windsor Road (east) A 3.0m off road shared pedestrian / cycle path has been provided on the western side of the new road. New traffic signals are to be provided at the Samantha Riley Drive / Old Windsor Road and Old Windsor Road / Windsor Road intersections. Reconstruction of existing traffic signals is to be undertaken at the Merriville Road / Windsor Road intersection. Pavement Design The pavement design is 185mm of asphalt over 240mm of lean mix concrete over 300mm of select material zone. Major Structures A 14m extension to an existing 5 cell box culvert over Caddies Creek on Old Windsor Road forms part of the work. Property Affected Property acquisition requirements are outlined in Appendix C of the Concept Engineering Design Report. Acquisitions are required for 4 properties along the Windsor Road section of the project: Villaworld and the James Ruse Hotel on the west and the Muir property and Sydney Water property on the east. Combined acquisitions for the road widening and transitway project are required to the north of the Old Windsor Road / Windsor Road intersection on the eastern side (Muir and Sydney Water properties). Only costs associated with the road widening will be included in the estimate.

Page 2

Public Utilities The public utility impacts are outlined in the Public Utility Impact Report. Potential impacts are on overhead electrical services of Integral Energy, underground watermains of Sydney Water (generally road crossings), underground gas mains and a regulator of AGL and major underground telecommunications cables of Telstra and Optus. The Telstra cables are particularly significant coming out of the Kellyville exchange with 2 separate 2400 pair cables, one on each side of the road, plus optical fibre and smaller cable is being affected. Physical Constraints •

Heritage section of Old Windsor Road on eastern side of corridor

•

Prescribed dam upstream of Caddies Creek on western side of corridor

•

Stanhope Gardens residential subdivision on western side of corridor

•

Trunk water, gas and telecommunications utility services along western side of corridor.

•

Existing Old Windsor and Windsor Roads and the need to maintain traffic flow.

•

Commercial businesses along Windsor Road between Old Windsor Road and Merriville Road (eastern side)

•

Commercial businesses along Windsor Road adjacent to Merriville Road intersection.

Environmental Constraints •

A number of heritage sites are present in the area, in particular sections of the existing Old Windsor Road and historic boundary markers.

•

Effects of noise and vibration on nearby residences

•

Sensitivity of the creek and watercourses areas to development

•

Need to maintain or improve the visual amenity along the upgraded route

Geotechnical Issues •

The ground conditions, particularly at creek areas, may be susceptible to poor subsurface conditions leading to significant quantities of unsuitable earthworks material.

•

Poor existing subgrade will require importation of select and upper zone of formation material to provide a suitable foundation for pavement layers.

3 KEY ASSUMPTIONS/COMMENTS •

The project will be undertaken in two adjoining construction packages roughly each of 1.3km.

•

Utility adjustments can be undertaken in advance of roadworks, particularly on the northern contract

•

Property acquisitions, or, initially at least, leases over land, will be undertaken so as to have necessary portions of land available prior to construction requirements including those for utility adjustments.

MR635 Old Windsor Road & MR184 Windsor Road - Suunnyholt Road to Merriville Road - Detailed Estimate Report

MR 635 - OLD WINDSOR ROAD AND MR 184 - WINDSOR ROAD SUNNYHOLT ROAD TO MERRIVILLE ROAD DETAILED ESTIMATE REPORT 1 SUMMARY The estimated cost of the Project is $32 million in 2000/2001 financial year dollars or $33 million in out turn dollars. See Appendix A for the Estimate Summary, Subsidiary Sheets and Cash Flow Table. This is a Detailed Estimate. The estimate is based on the Detailed Design (part complete) dated February 2001, Concept Design dated January 2001 and draft Review of Environmental Factors (REF) dated December 2000.

2 SCOPE The following information provides a description of the scope of work: Location The Project is located between the Sunnyholt Road on Old Windsor Road and 300m north of Merriville Road on Windsor Road. It is located within both the City of Blacktown (western side) and Baulkham Hills Shire (eastern side). ROADLOC Reference Old Windsor Road

Start: 0000635/0120/A/0.150 Finish: 0000635/0120/A/1.950

Windsor Road

Start: 0000184/0230/A/0.000 Finish: 0000184/0230/A/0.782

Limits of Work The work extends from the Old Windsor Road / Sunnyholt Road intersection and extends northwards along Old Windsor Road and then Windsor Road to 300m north of the intersection of Windsor Road and Merriville Road. Length: 2,700m. The work is shown on the Concept Design Plan attached in Appendix B. Design Drawings Concept Drawing No.0635.040.CD.0001 (attached to the REF) Detail Design Drawing 0635.040.RC.2501 (Sunnyholt Road to Caddies Creek) * Note: Detail Design of the next section from Caddies Creek to north of Merriville Road is not complete at the time of completion of the estimate.

Type of Construction Reconstruction and widening on a new and existing alignment, with the Old Windsor Road portion being on new alignment slightly to west of existing and the Windsor Road portion being widened on the existing Windsor Road alignment. Cross Section & Design Divided carriageway with two 3.25m wide lanes in each direction along Old Windsor Road and then three 3.25m wide lanes in each direction from 200m south of the Old Windsor Road / Windsor Road intersection to the northern limit of the work. A shoulder, 1.5m wide is provided on each carriageway on Old Windsor Road plus a 1.5m verge in fill areas or a 1.0m SO gutter in cut areas. Median width is 4.5m minimum up to 9.0m. On Windsor Road a 1.5m shoulder has been allowed in the southbound direction along with 0.7m wide SA kerb and gutter on both sides. Turn lanes of 3.0m are provided at the Samantha Riley Drive, Windsor Road and Merriville Road intersections. Provision for double right turns is incorporated at all intersections plus a double left turn out of Samantha Riley Drive (east) into Old Windsor Road (south) and Windsor Road (south) into Windsor Road (east) A 3.0m off road shared pedestrian / cycle path has been provided on the western side of the new road. New traffic signals are to be provided at the Samantha Riley Drive / Old Windsor Road and Old Windsor Road / Windsor Road intersections. Reconstruction of existing traffic signals is to be undertaken at the Merriville Road / Windsor Road intersection. Pavement Design The pavement design is 185mm of asphalt over 240mm of lean mix concrete over 300mm of select material zone. Major Structures A 14m extension to an existing 5 cell box culvert over Caddies Creek on Old Windsor Road forms part of the work. Property Affect Property acquisition requirements are outlined in Appendix C of the Concept Engineering Design Report. Acquisitions are required for 4 properties along the Windsor Road section of the project: Villaworld and the James Ruse Hotel on the west and the Muir property and Sydney Water property on the east. Combined acquisitions for the road widening and transitway project are required to the north of the Old Windsor Road / Windsor Road intersection on the eastern side (Muir and Sydney Water properties). Only costs associated with the road widening have been included in this estimate.

Public Utilities The public utility impacts are outlined in the Public Utility Impact Report. Potential impacts are on overhead electrical services of Integral Energy, underground watermains of Sydney Water (generally road crossings), underground gas mains and a regulator of AGL and major underground telecommunications cables of Telstra and Optus. The Telstra cables are particularly significant coming out of the Kellyville exchange with 2 separate 2400 pair cables, one on each side of the road, plus optical fibre and smaller cable is being affected. Physical Constraints •

Heritage section of Old Windsor Road on eastern side of corridor

•

Prescribed dam upstream of Caddies Creek on western side of corridor

•

Stanhope Gardens residential subdivision on western side of corridor

•

Trunk water, gas and telecommunications utility services along western side of corridor.

•

Existing Old Windsor and Windsor Roads and the need to maintain traffic flow.

•

Commercial businesses along Windsor Road between Old Windsor Road and Merriville Road (eastern side)

•

Commercial businesses along Windsor Road adjacent to Merriville Road intersection.

Environmental Constraints •

A number of heritage sites are present in the area, in particular sections of the existing Old Windsor Road and historic boundary markers.

•

Effects of noise and vibration on nearby residences

•

Sensitivity of the creek and watercourses areas to development

•

Need to maintain or improve the visual amenity along the upgraded route

Geotechnical Issues •

The ground conditions, particularly at creek areas, may be susceptible to poor subsurface conditions leading to significant quantities of unsuitable earthworks material.

•

Poor existing subgrade will require importation of select and upper zone of formation material to provide a suitable foundation for pavement layers.

3 KEY ASSUMPTIONS/COMMENTS •

The project will be undertaken in two adjoining construction packages roughly each of 1.3km.

•

Utility adjustments can be undertaken in advance of roadworks, particularly on the northern contract

•

Property acquisitions, or, initially at least, leases over land, will be undertaken so as to have necessary portions of land available prior to construction requirements including those for utility adjustments.

4 RISK CONTINGENCY ASSESSMENT Risk

Contingency

Incomplete detail design

The Project Management Note, PMN-004 recommends are contingency range for detailed estimates of 10-20%. Due to the detail design being incomplete the upper extent of this range is being adopted generally in the estimate i.e. 20%

Unsuitable ground conditions

Detailed analysis of the geotechnical reports has been undertaken by the designers in determining likely amounts of unsuitable material. The figure calculated has been increased by 50% which corresponds with approximately 10% of the earthworks cut/fill quantity.

Utility adjustments will have consequential effect requiring greater scope of work

Allow for increased contingency to 30% ($825K)

Property acquisitions may not be agreed in a timely manner

Identify timeline for acquisitions with alternative/parallel strategy for compulsory acquisitions. Also investigate leases of land prior to finalisation of acquisition

5 ESTIMATING PROCESS The quantities for the estimate were prepared by the road designers, Hyder Consulting. The estimate has been prepared using rates from similar recent projects obtained by the Project Support Officer, David Adams. The rates have been reviewed by the Project Manager, Peter Letts.

7 CONSTRUCTION RISK ASSESSMENT High Risk Items

Risk Response

Culvert extension at Caddies Creek delayed by poor ground or water flows

Work separated out from contract works to be undertaken as advance construction so as to isolate any potential delays

Unsuitable ground conditions

Unsuitable allowance of 10% of earthworks quantity and 20% of drainage excavation allowed in tender Schedule of Rates.

Utility adjustments may not be completed before construction commences

Include specification clauses on access to portions of the work which deal with the timing of utility adjustments and allow for their completion. Also review staging to minimise timing risk.

Access to property may not be available before construction commenced.

Include specification clauses on access to portions of the work which deal with the timing of utility adjustments and allow for their completion. Also review staging to minimise timing risk.

PURPOSE The purpose of this procedure is to describe the process of project review, which is to be undertaken upon finalisation and handover of the project.

SCOPE Applicable for all development projects undertaken by Project Management Services Branch.

OVERVIEW Post-completion project review must be undertaken for all development projects and is the responsibility of the Project Manager. The review includes a broad assessment of all aspects of the project, including: • • • •

Review of overall project outcomes against project objectives Review of the performance of contractors Self-assessment of the performance of PMS in the provision of project management services A summary of lessons learnt from the project that can be passed on to other PMS project managers.

All of these reviews should be completed by the Project Manager within 1 month of project handover.

RESPONSIBILITIES The Project Manager is responsible for undertaking and documenting each of the reviews outlined in this procedure. The Project Manager is also responsible for distributing outcomes of these reviews to the Project Management Development Manager, Project Management Office. The Project Management Development Manager, PMO is responsible for reviewing project review documentation, for initiating improvements in project delivery methodology and for distribution of project review documentation to Project Managers through PMS Learning Workshops. The Contract Development Manager, PMO is responsible for reviewing the results of contractor reviews and for initiating improvements in contract delivery The Quality and Systems Manager PMO, is responsible for initiating and managing system improvements to address issues raised as the result of project reviews.

ACTIONS 1. Performance Against Project Objectives The Project Manager is responsible for undertaking a review with the Client’s Representative of overall project performance against the Client’s project objectives. These objectives may be either stated (as per the project brief) or implied, and should focus special attention upon environmental and community involvement issues. The Project Manager shall document the discussion and a copy of the review shall be issued to the Project Services Manager, and the Project Management Development Manager for information.

2. Contract Performance The Project Manager will complete a performance review of the Contractor in accordance with the standard RTA Form 517 The Project Manager will complete a performance review of Consultants and Professional Service Contractors in accordance with the standard RTA Form 550 These forms are available in RTA forms manager, located on the intranet. These forms are also built within PROMIS and linked with Contract Finalisation Reports. A copy of these reviews shall be issued to the Senior Project Manager/Project Services Manager, and the Contract Development Manager for information.

3. Management Performance The Project Manager will complete a “self-assessment” which reviews the effectiveness of PMS services for the project. This review will include: • Effectiveness of PMS systems and controls in the management of the project • Review of actual PMS project management costs against budgeted fees • Effectiveness in delivery of the project to budget and program • Breakdown of project costs usingthe Project Management Guidelines, Tables 6.1 & 6.2 in PMG-01 “Level 1 & 2 Benchmark Rates Forms”. This will be issued to the Estimating Manager, PMO to assist with furture estimates. A copy of the review shall be issued to the Project Services Manager and the Manager, PMO and will be used as a basis for ongoing business improvement.


Issue 2.0

Page 3 of 4

Post-Completion Project Review 4. Learning The Project Manager will document a summary report of lessons learnt from the projects. The report should be structured under the following headings as applicable: • Objectives • Environmental Assessment • Concept Design • Detailed Design • Construction • Management • Community Involvement • Risk Management • Environmental Protection A copy of this document shall be issued to the Project Management Development Manager for dissemination of information to all PMS offices and as a basis for ongoing business improvement.

5. Learning Workshops Upon review of the above documentation the Project Management Development Manager may determine that there would be a benefit in conducting a workshop for project management staff to discuss project management issues in the form of a case study. If a workshop is held, the Project Manager will hand over all presentation materials to the Project Development Manager at completion of the workshop for inclusion in a central reference file.

QUALITY RECORDS Copies of all reports and reviews as referenced in this report are to be retained in the project file. The Project Development Manager is responsible for retaining all learning workshop training records. The Contract Development Manager is responsible for retaining all records of Contractor performance review.

CONTRACT VARIATIONS

CHAPTER0

9.1 Summary This section sets down the processes for the valuation of contract variations.

9.2 Contract Variations The principles utilised in the preparation of pre-contract estimates can also be adopted when assessing major variations prior to them being proposed by RTA, and in assessing variation requests from a contractor. The pricing of a variation must be prepared in a way that is explicit and consistent and which takes into account the method of construction and the circumstances and timing during which the variation occurs. A sound pricing exercise can only be performed when each operation or item is analysed into its simplest elements and the cost estimated methodically on the basis of factual information. This pre-supposes that the variation cannot be priced by reference to contract rates. The pricing of a major variation may have important and far-reaching effects. The extent of the impact that a major variation may have on a project has to be considered and taken into account and reflected in the final value of the variation. The most frequent consequence of the introduction of contract variations is that the contractor will make a claim for additional time and cost. Where appropriate, it is a good variation pricing practice to take this into account at the time of agreeing the variation. It must also be noted that a variation may also result in the deletion of certain parts of the works and a possible reduction in the time required to perform the variation.


Contract Variations Issued December 2001

• • • • • •

9-1

One of the fundamental principles of pricing contract variations is that, in common with the pricing of the original estimate, the items or operations are priced net, that is, it should initially be an assessment of direct costs without any adjustments for indirects, overheads and profit. The calculation of indirects, overheads and profits should only be addressed when the direct cost pricing has been completed and the additional time involved (if any) can be calculated for incorporation in the cost.

10.1 Summary This chapter provides general information only on some proprietory software availble as an aid to estimating, including: • • • • • • • •

MS Excel and similar spreadsheets Build Soft CATS Candy Piece 7 (Wintendor) Benchmark Estimator V6 Expert Estimator

Brief descriptions and comments are given. Any intended applications of the specialist estimating software (that is, excluding spreadsheets) should be referred to PMO for advice.

10.2 Estimating Software Common proprietory estimating software used by the Australian Construction Industry includes the following; • • • • • •

• Expert Estimator

10.2.1 Microsoft Excel and Similar Spreadsheets Spreadsheets are used by some smaller contractors together in some instances with custom macros. However, this approach to estimating is not generally preferred by most professional estimators due to the ease of making errors and the lack of custom built features which assist in the assembly of large estimates.

10.2.2 Buildsoft Buildsoft is used by commercial building companies and is good for take offs and subcontract work but has not found widespread application in civil engineering projects.

10.2.3 CATS CATS is an in-house estimating system developed by the Leighton Group of companies and is not commercially available, although there are a number of clones available in the market, the most popular of which is Expert Estimator.

The following five packages all provide the level of detail required for large civil estimates as well as the ability to develop nested group resources (sometimes called assemblies or clusters). This is an extremely useful feature in civil engineering estimating.

10.2.4 Candy Candy was developed by the South African company Murray & Roberts over 10 years ago and is available in the market place in Australia. It is used by a number of large civil engineering companies.

Candy has all the features required to build up a complex estimate. It is, however, quite complex to use (due to the large number of features in the package) and requires a good deal of training to be used efficiently.

10.2.5 Price 7 (Wintender) Price 7 is used by at least one of the major Australian civil engineering companies. It is a South African product and has recently been upgraded from the DOS version to a MS-Windows version called Wintender. The package is simple to use and little training is required. Suppliers are: HKC Systems Tel +27 12 665 000 e-mail [email protected]

10.2.6 Benchmark Roadworks Strategic Estimator Benchmark Roadworks Strategic Estimator is a powerful tool for the Strategic estimator. This feature of the benchmark software, written in co-operation with RTA, enables the estimation of projects progressively from Strategic, to Concept and detailed all in the one package. Strategic and Concept estimates, including quantities and rates, are generated automatically when the user answers just a few RTA Project Estimating Edition 1, Revision 0

questions. When the estimate needs to be further refined the user simply answers more questions to refine the estimate further. Benchmark is Windows based and is multi-user. It has all the features required for advanced estimating and is easy to learn and use. Import and export facilities to and from other packages, especially programming packages like Microsoft Project, further increase the utility of the program. The package is fully supported and is continually being developed. Further information is available from:

10.2.8 Expert Estimator Expert Estimator is a clone of the CATS software used by Leighton Contractors. In mid 2000, Version 3 was released which for the first time had full MS-Windows features. Expert Estimator is a very large program with many options and the ability to handle the largest projects. Much more has been done on version 3 since its release and it is now being used extensively in the industry. Despite the number of options and reports which can be obtained from the package it is fairly simple to use. A powerful computer is required to make the most of the package.
