PREFACE The Rail Method of Measurement has been written to provide a basis for the elemental cost analysis, measurement and valuation of all costs of a project, whether they are incurred by the infrastructure owner or the contractor thus providing, if so desired, Total Cost Management of Projects. In order to efficiently and effectively manage their assets, Asset owners require certainty of cost for their capital investment and maintenance programmes through the project lifecycle to enable sound decisions to be made on where, when and how to invest. Increased accuracy at the early stages of the project lifecycle achieves this, but also minimises abortive cost/spend on non-viable investments thereby improving overall capital efficiency. The Rail Method of Measurement (RMM) has been written to provide a progressive integrated measurement and valuation process in context with project development and delivery processes used by railway infrastructure owners, network operators and suppliers in the UK. The RMM provides a structure for the consistent preparation of budgets for capital and maintenance works to a railway asset such that there is understanding between all involved parties as to where cost items are covered, how they should be measured, what they include, and if relevant what cost items are not included.

Foreword to Rail Metho d o f Measur ement – Volum e 2 – Detailed Measurement Mature construction sectors have well established cost planning and modelling frameworks that allow funders, clients and stakeholders to make clear assessments of the value for money and cost drivers associated with their schemes. These frameworks of rules and definitions are usually developed and published by the professional institutions and well honed examples include the New Rules of Measurement suite (NRM 1-3) published by the Royal Institution of Chartered Surveyors and the Civil Engineering Standard Method of Measurement (CESMM4), published by Institution of Civil Engineers. Commercial practitioners from estimators and procurement professionals through to post contract managers and Quantity Surveyors are well versed in the application and benefits that these frameworks bring. The establishment of such a framework for the rail industry is fundamental to our ability to illustrate what rail infrastructure schemes ‘should’, ‘will’ and ‘did’ cost and perhaps as importantly, ‘why’. Illustrating what rail investment schemes should cost is a perennial challenge and in order to provide a coherent answer, a common language is needed to instil crossindustry consistency and support improved domestic and international analysis and benchmarking. Such a language must be based on a standard hierarchy of definitions and nomenclature for the description, measurement, pricing and modelling of rail infrastructure works. That language, developed in collaboration with an Industry Development Group is a suite of documents collectively referred to as the Rail Method of Measurement (RMM). It comprises three volumes: Volume 1: Cost Planning - Standard Cost Planning for Rail Infrastructure Works Volume 2: Detailed Measurement - Standard Descriptions of Works Activities Volume 3: Operational Maintenance - Standard Descriptions of Operational Maintenance Activities Volumes 1 and 2 have been released as part of a broadened industry consultation. Volume 3 will follow. Volume 2 provides guidance on the quantification and description of rail infrastructure works for the purpose of quantification in support of schedules of works, estimates, pricing documents, final accounts and the constituent elements of cost models. Direction and definition on how to address ‘non physical’ items such as preliminaries, overheads and profit, design costs and risks is also given. Adoption by practitioners will provide a uniform basis for measuring and describing rail infrastructure works and embodies the essentials of best practice. The work of the Industry Development Group will continue with the refinement of volumes 1 and 2 in light of industry feedback, and the validation and first release of volume 3. Comments, proposed revisions and amendments to the documents are welcome and should be sent to [email protected] Requests to formally contribute to the Industry Development Group’s ongoing activities are also welcome. The successful introduction of the Rail Method of Measurement and associated unit cost modelling is an important element in driving industry change and leaving a lasting legacy in the rail sector. In time it will support the industry’s ability to better demonstrate value for money, the capital cost dynamics of rail infrastructure schemes, enable whole life costing and facilitate improved transparency and consistency. This will only happen with the overt support from industry stakeholders and adoption by client and supply chain practitioners. It has been a privilege to facilitate this work from concept through to industry deployment and I would like to thank members of the IDG and other stakeholders for their active collaboration in bringing a fit for purpose product to industry.

Principl es of Application

1.01

Introduction

The Rail Method of Measurement (RMM) Suite of Documents provides the guidance for consistent measurement and cost analysis of works to railway infrastructure.

1.02

Purpose

The Rail Method of Measurement provides a consistent basis for description, measurement and allocation of cost for railway works, and embodies the knowledge of current industry best practice. It enshrines the common language within which the works required and the costs planned and eventually incurred for the complete development and delivery of capital and operational investment projects can be described and understood. It covers all aspects of client and contractor involvement within the project lifecycle. Volume 1 provides the framework to create a cost plan for the required outcome using a ‘top down’ methodology. As the solution develops through its lifecycle into pre-construction stages, greater certainty of cost is provided by more specific and detailed itemisation of tasks required to complete the outcome. In addition, Volume 1 provides the standard hierarchy and framework through which all costs at any development or delivery stage can be analysed and reconciled for comparison. Volume 2 provides the required level of detail to produce ‘bottom up’ cost plans, estimates, and detailed pricing schedules in a manner consistent with other construction sectors. Volume 3 provides the required level of detail to produce estimates and pricing schedules for works required to keep the railway operational between capital investment stages, through classification of major groupings of maintenance activities, including inspections, servicing and maintenance works items Asset Lifecycle – Increased Knowledge

Figure 1 : Rail Method of Measurement application across asset lifecycle

Through the use of Volumes 1, 2 and 3 of the RMM all costs incurred from the inception of a project to the ultimate disposal of the asset can be consistently measured, priced and recorded to complete the circle of cost knowledge.

1.03

Struct ure of the RMM Suite of Documents

RMM Volume 1 (Cost Planning) provides a standardised list of Cost Categories and Group Elements within a hierarchical cost breakdown grouped principally by railway asset groups, 7


then element assets or systems, sub-elements and components (e.g. Permanent Way; Plain line; Running rails; Modular track) RMM Volume 2 (Detailed Measurement) provides a standardised list of railway specific work classifications (e.g. Rail Track, Railway Control Systems, Electric Power Installations) incorporating railway asset specific sections for M&E type works, using the principle of “one item, one place”, such that each item appears only once but can be used and allocated once or multiple times within the estimate or pricing schedule and against the RMM 1 structure. RMM Volume 3 (Operational Maintenance) provides the same principle as RMM 2, but re-uses the railway asset groups to classify the work items more in line with the order of work activity taking place (patrol, inspection, repair, etc).

1.04

Use of the RMM Suite of Docum ents

The figure below gives an example of how RMM 1 and RMM 2 work together and compliment each other. RMM 1 provides the Cost Categories, Group Elements and Element structure which shall apply for all Cost Planning, Detailed Estimates and the Valuations of all Project Costs through the Project Lifecycle. RMM 1 is used for Cost Planning purposes however when more design information is available the RMM 2 can be introduced to provide a more granular level of Measurement yet still correlating back to RMM 1 and the Cost Categories, Group Element and Element structure. Figure 2 – How RMM 1 and RMM 2 work together

1.05

Format and Layout

All RMM Volumes are set out in tabular form to provide the method of measurement and valuation; each section includes rules relating to measurement, definition, coverage and additional information or additional description required to be given.


8

RMM 1 divides the costs of works generally encountered within the Railway Corridor into six cost categories: 1.

Direct Construction Works

2.

Indirect Construction Works

3.

Employer’s Indirect Costs

4.

Risk

5. Inflation 6. Taxation Each Cost Category comprises one or more Group Elements, which provide a breakdown of cost in increasing detail: Elements, Sub-elements, and Components. It is intended that as the level of maturity of the project increases, so a greater level of breakdown of cost items can be measured.

1.06

Ali gnm ent wit h CESMM 4

RMM 2 provides supplemental information to the Civil Engineering Standard Method of th Measurement, 4 Edition (CESMM4) rules and principles to amplify and encompass specific works to railway infrastructure and systems. This document should be read in conjunction with CESMM4 to enable a full and complete breakdown of work items to be provided for railway infrastructure projects.

1.07

Form of Contract

RMM is “contract agnostic” - it makes no reference to any particular form of contract as it is intended for application to any project, irrespective of the form of contract between the parties. The term “contract” is used, generically, to make reference to the requirements of the contract being used for the project, where those requirements affect the method of construction or the cost of the works.

9


1.08

Cost Analysi s, Benchmark Analysi s and Cost Models

The RMM can be used as the basis for capturing current and historical data in a common format. This allows for consistent Cost Analysis, Benchmark Analysis and Cost Modelling. Both the Cost Analysis and Benchmark Analysis techniques will be based on the Group Element and Element Cost Summaries as shown in Appendix A and B. An example of a Cost Model based on the RMM format is shown in Figure 3. As well as the RMM format it is important to note that Cost Models will also be determined by their ‘Cost Drivers’ and ‘Technical Parameters’ with examples shown. Figure 3 – Cost Model example

1.09

Details of work s

Unless otherwise specifically stated in the cost plan, estimate or pricing schedule, all works described and measured in accordance with this document shall be deemed to include provision of goods, materials and services necessary to carry out the described items. Items measured using the rules contained in this document shall fully describe the quantity and quality of the required works. Where a specific area of project works requires a greater level of detail than the ‘Component’ level, RMM Volume 2 – Detailed Measurement, or RMM Volume 3 – Operational Maintenance shall be utilised to define the precise extent, nature and specification of the required works. Items of works or groups of items shall be classified to define the type of work activity being carried out, in accordance with the definitions listed below:

11

New Build

New installation on greenfield / brownfield site works where no similar type of asset exists.

Replace – Full

Replacement / reconstruction of all life-expired structural components with equivalent or lesser specification components.

Replace – Partial

Replacement / reconstruction of targeted life-expired structural components with equivalent or lesser specification components.

Refurbish

Renovation or overhauls of existing asset or components / elements, including e.g. redecoration, cleaning, remove graffiti / vegetation, etc. Also includes minor remodelling & upgrades.

Upgrade (Enhance)

Improvement of existing asset to provide additional benefit or functionality over that it currently exhibits.

Remodel / Alter

Modifications in layout or location but with functionality of elements unchanged.

Extend

Hazard Management

Planned programme of work to reduce risk; works or treatments to remove or make safe existing hazards within assets or components, other than strengthening.

Abandon / Demolish / Remove

Removal of an asset, the functionality or liability of an asset without replacement. Where this entails works other than demolition (e.g. Infilling) to remove functionality, this shall be classed as replacement.

Asset Protection

Infrastructure owner supervision only of works to assets which impinge on railway land but are owned and constructed by outside parties.

Use of the Work Classi fic ations

NOTE: Information contained within this section is to be read in conjunction with the relevant sections of CESMM4 to obtain full understanding and compliance with the guidance contained herein.

2.01

Descriptions

If it is necessary for the Detailed Estimate / Pricing Schedule / Bills of Quantities to be structured by a Work Breakdown Structure or other means of organisation, this structure should either form the high level headings or be attached to each item, so as to preserve the alignment of the current estimate/schedule/BoQ with that structure.

2.02

Coding for Cost Analysi s

In order to provide a means for consistent analysis of cost and to compare to previous budgets, documents produced using Volume 2 of RMM shall be referenced and coded to the corresponding Cost Category and Group Element as set out in RMM Volume 1.

3.01

Referenc e Terms

The following reference terms shall be found within this document, and the meanings assigned to them are detailed below: “ Anticip ated Final Cost (AFC)” – means the estimated final cost of a project at completion, i.e. a forecast of the total expenditure for development and delivery of the entire project at close-out. This may or may not be equal to the Cost Limit. – see Cost Limit. “Bill(s) of Quantities ” – means a list of items giving brief identifying descriptions and quantities of the work. “ Component ” – means a measured item which forms part of an element or sub-element. The quantity of one or more items is measured and the rates and prices entered to calculate the cost target for an element or sub-element. “ Consolidated Unit” – means an item of work described from a combination of components within a sub-element. “ Contract ” – means the Conditions of Contract, the Specification, the Employer’s Requirements, the Contractor’s tender or proposals and the written acceptance thereof, together with such other documents as may be expressly agreed between the employer and the contractor and referred to in the Contract Agreement(where completed). “Contractor ” – means the individual or incorporated body responsible for the total construction and completion process of the works. Where the works are let in defined packages, the term “contractor” may apply to the legal entity constructing each of the packages. “ Contractor’s equipment ” – means all appliances or things of whatever nature required in or about the construction and completion of the works but do not include materials or other things intended to form or forming part of the permanent works. “ Contractor’s overheads and profit” – means the contractor’s costs associated with head office administration proportioned to each works contract plus the contractor’s return on capital investment. Contractor’s overheads and profit exclude costs associated with sub-contractor’s overheads and profit, which are to be included with the rates for the sub-contractor’s work. “ Contractor’s preliminaries ” – Contractor’s preliminaries include the costs associated with such items as management and staff, site establishment and maintenance, site supervision, requirements under the contract, temporary works and temporary services. Contractor’s preliminaries exclude costs associated with sub-contractor’s preliminaries, which are to be included with the rates for sub-contractor’s work. “ Contractor’s risk” – means the allowance added to the tender calculation for the commercial risk associated with competitive tendering. “Construction Cost” – means the total cost of the Direct and Indirect Construction Works cost (i.e. the total cost for the works including the Contractor’s preliminaries, overheads and profit). “Construction and Development Cost” – means the total cost of the Construction works and the Employer’s Indirect Costs. “ Construction inflation” – See “Inflation”. “ Construction package” – means a part of the programme or project form part of the works which let to one or more contractors. “Cost Category” – the term used to differentiate at the highest level types of costs incurred on a project, distinguishing between cost of physical works and other cost areas. “ Cost control” – means the process of planning and controlling the costs of the programme and projects throughout the complete programme or project. “Cost estimate” – means a report determining the possible cost of a project early in the design process in relation to the Employer’s fundamental requirements. This is prepared prior to the preparation of a full set of working drawings or specification or Pricing Document and forms the initial stage in the cost planning process. 13


“ Cost limit” (or authorised budget or approved budget ) – means the maximum expenditure that the employer is prepared to make in relation to the completed programme or project. “ Cost plan” – see elemental cost plan. “ Cost target” – means the recommended total expenditure for a group element, element or sub-element. The total cost for an element is likely to be derived from a number of subelements and components; a cost target may be set for a sub-element as the design development progress, the aggregate of cost targets for each of the sub-elements within an element form the target cost of the element and the aggregate of the cost targets for each element form the cost target for the group element and so on. “ Design and buil d cont ract” – means a contract by which the design and construction of the works are the responsibility of the contractor. “ Design team” – means project managers, engineers, cost managers and specialist consultants responsible for the conceptual design and its development into drawings, specifications, instruction and schedules required for the construction of the works. The design team is part of the project team. “ Direct Construction Works Cost” – means the labour, plant, material, and subcontract costs for the provision and installation of the permanent works. Direct Construction Works Costs exclude ‘Contractor Preliminaries’, ‘Contractor Overhead & Profit’ and ‘Design’. “ Element” – means the principal division of a group element. Elements provide the standard level of cost planning or analysis. A separate cost target can be established for each element from the sum of the underlying sub-elements. “ Element Unit Quantity” (EUQ) – means the unit of measurement that relates solely to the quantity of the element or sub-element (e.g. the length of track, the number of switches or crossings and the length of drainage). “ Element Unit Rate” (EUR) – means the rate derived from the total cost of the element divided by the element unit quantity (EUQ). For example, the EUR for permanent way is the total cost of track, turnouts and crossings, ancillaries, track drainage, treatment of existing track abandonment and recovery of old materials, survey and recovery of old materials, testing and commissioning, contractor’s design and contractor’s overheads and profit, divided by the EUQ for permanent way. EURs include the cost of all labour, materials and plant, sub-contractor’s design fees, sub-contractor preliminaries and sub-contractor’s overheads and profit. EURs exclude contractor’s preliminaries, contractor’s overheads and profit and other costs such as project team fees, other development/project costs, risk allowances and inflation. These items are assessed separately. “ Elemental cost analysis” (or cost analysis) – means a schedule of detailed costs of previously constructed works and is intended to provide information to assist the accurate estimate of cost of similar future works. Based on completed projects, it contains data on which initial elemental estimates and elemental cost plans can be based. “ Elemental cost plan” (or cost plan) – is the critical breakdown of the cost limit for the project into cost categories and group elements for each element of the project. It provides a statement of how the design and delivery team proposes to distribute the available budget among the elements of the project and a frame of reference from which to develop the design and maintain cost control. It also provides both a work breakdown structure (WBS) and a cost breakdown structure (CBS) which, by codifying, can be used to redistribute work in elements to construction packages for the purpose of procurement. “ Employer ” – means the promoter or owner of the works. The terms “Project Sponsor” or “Supervising Officer ” (SO) are used to define representatives of the Employer empowered to manage the works project and, unless otherwise provided in the contract, issue instructions or notices on behalf of the Employer. For the purposes of RMM, the term “ Employer” shall be synonymous with the terms “Project Sponsor ” or “Supervising Officer ” (SO). “ Employer’s Indirect Costs” – means the total costs incurred by the Employer in the development, design and delivery of the project, excluding the Construction Cost. “ Enabling Works” – means the works required to be completed prior to the commencement of the principal works within the “railway corridor”.


14

“ Engineering hours” – (for the London Underground network), means the period of time between (a) the published time or actual time, if later, traction current is switched off and (b) the published time or amended time, if earlier, traction current is switched on. “ Estimate” – see Cost estimate. “ Estimate base date” – means the date on which the cost limit (excluding inflation – i.e. the sum of the works cost estimate, project/design team fees estimate, other development/project costs estimate and risk allowance estimate) is established as a basis for calculating inflation, changes or other related variances. “ Estimate of Prime Cost [EPC] – means the estimate prepared to calculate the probable “target cost” for a cost reimbursable contract; the EPC is used to exercise size cost control. “ Expressly required” – means shown on the drawings, described in the specification or ordered by the Employer pursuant to the contract(s) in use. “Four-foot” – means the space between two running rails of standard gauge track. “ Four-foot walkway” – means a track asset walkway which runs along the four-foot of a track, to give access to, or egress from, a stabled train or rail-mounted vehicle. “ Free issue services, materials or plant” – means items that are supplied to the Contractor through Employer facilitated contracts. These items should not incur ‘Contractor Overhead & Profit’. “Group Element” – means the principal headings used to describe the cost groups in an elemental cost plan. Group elements are the principal division of cost categories and provide the highest level of elemental cost planning or analysis. A separate cost target can be established for each group element from the sum of the underlying elements. “ Indirect Construct ion Works Cost” – means the Contractor’s preliminaries, overheads, profit, and any other costs associated with the execution of the works excluding the direct construction works costs. “Inflation” – an allowance made for the rate of change of prices (as indicated by a price index) calculated on a monthly or annual basis. Refer to definitions for tender inflation and construction inflation as follows: “ Construction inflation” – means an allowance included in the Cost Estimate or Cost plan for the rate of change of prices for labour, plant and materials during the period from date of the tender return to the completion of construction work. “ Tender inflation ” – means an allowance included in the Cost Estimate or Cost Plan for the rate of change of prices from the estimate base date to the tender return date. The allowance may include for inflation brought about by changes in market conditions or for the rate of change in the prices of labour, materials and plant and equipment during the period from the estimate base date to the date for tender return. “Isolation” – means: (a)

the formal procedure for de-energizing a section of traction current supply equipment, earthing, verifying its lack of potential and issuing certification to that effect, or

(b)

the severance of any electrical supply to electrically operated devices, lineside cabinets and the like.

“ Overheads and Profit” – See Contractor’s overheads and profit. “ OGC Gateway Proc ess” – means the Government process in the United Kingdom, which examines projects at all stages of their delivery from inception to completion. The process requires a business case to be prepared for the project, which is progressively reviewed until a decision to invest is taken. Following the investment decision, the project is monitored to ensure the business case is maintained and the project delivers its intended benefits to the Employer. “ OGC Gateways” (or OGC Gateway) – are the milestone decisions taken in the process. “ Other development/project costs ” – means costs that are not necessarily directly associated with costs of constructing the works but form part of the total cost of the project to the Employer (e.g. land acquisition costs, funding costs, fees to local authorities for statutory consents, decanting and relocation costs). 15


“Package” – means a self-contained section or discrete sections of works brought together for delivery under one contract or sub-contract. “ Period” – means the time calculated from the date of the order of cost estimate (OCE) or the date of the contract to the time for completion of the programme or project. “ Permanent works” – means the permanent works to be constructed and completed in accordance with the contract. “Possession” – means the circumstances obtaining when arrangements have been made to block the line to normal passage of trains and the only movements allowed are those of ontrack plant or engineering trains and the limits of demarcation of possessions are shown by possession board limits. “ Preliminaries” – See “Contractor’s preliminaries”. “ Pricing document” – means a set of requirements included in a contract to calculate the contract price and forming part of the contract to exercise cost control and to value change. “ Pricing schedule” – means a list of items, prepared in accordance with this document, giving brief identifying descriptions and indicative quantities of the work comprised in the project. See also Bill(s) of Quantities. “ Principal works” – means the works covered by group elements 1.01 to 1.08 inclusive, when the enabling works have been completed. “ Procurement Strategy ” – means the forms and methods for the programme and the works stated in reports prepared in accordance with this document. “ Project” – means the works executed in the railway corridor and all associated buildings required to be constructed forming part of the permanent works. “ Project team” – means Employer, Project Sponsor, Supervising Officer and all other consultants responsible for the delivery of the project to the required performance (design and quality) and cost criteria. The project team will include the contractor and sub-contractors where they have been engaged to provide pre-construction services. “ Project/desig n team fee(s)” – means project and design teams consultants fees for preconstruction, construction and post construction related services, other consultants fees, fees and charges for intrusive site investigations, specialist support consultant’s fees and contractor’s fees for pre-construction services. “ Programme” – means a series of projects co-ordinated within an overall plan to develop the railway corridor in whole or in part.
