Executive Summary This report summarises the results of feasibility work undertaken on the proposed Pimlico – Nine Elms pedestrian and cycle bridge. This feasibility work was carried out in three stages, covering location and landing concepts, demand and keys plan ning/environmental issues, and the engineering requirements and business case. A number of alignment options op tions have been considered, however at this stage there is no clear consensus amongst key stakeholders about which option should be pursued. Regard less of which option is pursued, careful consideration will need to be given to environmental, planning and heritage issues associated with the main bridge span and landings on both banks of the r iver. Results of the studies indicate that a bridge in this stretch of the Thames appears feasible in engineering and construction terms. The large distance between existing bridges in this location (relative to others in central London), combined with new demand generated by the development of the Vauxhall Nine Elms Battersea Opportunity Area, means that there is a high potential demand for the crossing. Nonetheless there are some significant issues to be resolved around bridge location and landings. Potential demand will be significantly tempered by the bridge design and the likely need for stairs and lifts, which are required to provide the navigational clearance necessary to pr ovide safe clearance for river traffic. Initial work suggests that achieving ramps on both banks is likely to be difficult due to the height of the bridge structure. Construction cost estimates suggest that the cost of a bridge serving the centre of the Opportunity Area could be in the region of £40 million (current prices), based on either a tied arch or cable stayed structure accessed at both ends via stairs and lifts. These costs are based on concept designs and there may be scope to design a lower cost str ucture once more information about the location is known. Next steps could include public consultation and the launch of a design competition in order to identify the optimum design for a bridge structure in this location.

Feasibility study summary report

1. Introduction Transport for London (TfL) has undertaken a feasibility study into the potential for a new pedestrian and cycle bridge across the River Thames between Chelsea and Vauxhall bridges, working in conjunction with the London Boroughs of Wandsworth and Lambeth, Westminster City Council, the Nine Elms Delivery Team, the GLA and key developers. This report summarises the feasibility study. The bridge would link the established residential area of Pimlico on the north bank with Nine Elms on the south bank, an area currently undergoing significant transformation.

Figure 1: Location plan

The feasibility study was completed between September 2012 and December 2013. A working group has been established to guide and inform the feasibility work, comprising representatives from the organisations listed above. This group has met at key stages in the study’s development and has been instrumental in gaining a good understanding of the issues associated with a scheme of this type and within this location. Should a decision be made to progress pr ogress with the bridge scheme, the feasibility study will represent a foundation on which further, more detailed planning work can be based.

2. Background The concept of a pedestrian and cycle bridge bridg e in this location was first identified in the Cr oss River Partnership Vauxhall Battersea Development Framework (2003) as a way to improve cross-river connectivity, and again in 2009 in a transport study co mpleted to inform the Vauxhall Nine Elms Battersea (VNEB) Opportunity Area Planning Framework (OAPF). In 2012, the proposal was adopted as a key part of the VNEB OAPF. The incumbent incumb ent Mayor of London made also made a manifesto pledge to: ‘examine whether there is demand for a new pedestrian river crossing, potentially between Vauxhall and Chelsea bridges as part of the Vauxhall Nine Elms development at Battersea, financed out of private funds.’

The OAPF and the Mayor’s manifesto pledge have been key drivers in this feasibility work.

2.1. Vision for Nine Elms The OAPF envisages the delivery of a high density mixed use development comprising 16,000 new homes and up to 25,000 jobs. Development will be phased p hased over a number of years, with construction underway and completion due in the early 2030s. The bridge is indentified within the OAPF as one of a number of transport schemes necessary to support this high level of growth, alongside such schemes as an extension of the Northern line to Battersea with two new Tube stations, enhanced bus services, improvements to National Rail stations, new passenger piers at Vauxhall and Battersea Power Station, pedestrian and cycle walkways, and new Barclays Cycle Hire docking stations. The bridge therefore represents one of a p ackage of measures to support the redevelopment r edevelopment of the Opportunity Area and enable a significant increase in population and employment to be realised. A brochure produced in summer 2013 providing an update on development plans for the area and how the bridge could contribute to these is attached as Appendix A.

2.2. Objectives of the scheme The primary objective of a new bridge bridg e is to improve connectivity to and from the VNEB Opportunity Area, improving access to jobs, homes, leisure opportunities and transport links in this part of the Central Activities Zone. It will improve access by foot and cycle for residents living north of the river to the jobs and leisure opportunities generated in the Opportunity Area (OA). Further objectives of the scheme are as follows: •

Increased mode shift from motorised modes of transport to walking and cycling, by reducing journey times and providing a new link Underpin the growth and regeneration foreseen f oreseen in the VNEB Opportunity Area by providing increased transport capacity and an ‘imag e boost’ which instils confidence that the area is developing in a progressive prog ressive manner Provide a better journey experience to many pedestrians and cyclists who currently have to use either Chelsea or Vauxhall bridge (shared with motorised traffic) Make a positive contribution to the urban realm in the area by encouraging local area movement and legible, high quality public spaces Feasibility study summary report

A new crossing in this location would contribute towar ds the delivery of a number of policies and proposals in the Mayor’s Transport Strategy (MTS) a nd the London Plan including:

•

MTS Challenge: Improving transport connectivity MTS Challenge: Improving accessibility MTS Proposal 60: Providing safe, comfortable and attractive environments for pedestrians London Plan Policy 6.4: Enhancing London’s transport connectivity London Plan Policy 6.9: Improving conditions for cyclists

3. Approach to the feasibility study In order to ascertain whether a new bridge between Nine Elms and Pimlico is achievable in engineering terms and support by sufficient demand, a certain level of feasibility work has been required. Building on the pre-feasibility study completed in June 2012, a pragmatic approach has been taken to completing this work, with the study split into t hree separate but related stages. These three stages are outlined below:

Stage 1 – Location and landing concepts This stage considered a total of five alignment potential options between Pimlico on the north bank and Nine Elms on the south bank. Two preferred options were identified as being most feasible (Options 1 and 2), for which further consideration was given to landing arrangements. This stage comprises the following reports: 

Location and landing concepts study – Buro Happold and J&L Gibbons – January 2013

Stage 2 – Demand and key planning / environmental issues The second stage focussed on the theoretical demand for a new crossing. Initial environmental and heritage assessments were also completed, focusing on the two preferred options identified in Stage 1. This stage comprises the following r eports: 



Initial heritage assessment – TfL – December 2012



Archaeological assessment – Mott MacDonald – April 2013



Arboricultural assessment – Hyder – February 2013

Stage 3 – Engineering requirements and outline business case Stage 3 considered the key engineering requirements and constraints that would need to be considered in the design of any new bridge, and a high level business case was produced based on demand outputs derived from Stage 2. Two bridge concept designs were developed to assist in identifying the constraints and parameters associated with the two preferred options, and to demonstrate how these could be addr essed. Further work was also undertaken on the merits of alignment Option 4, which would run adjacent to Grosvenor Railway Bridge. This stage comprises the following reports: 

4. Location options considered 4.1. Initial options considered See Stage 1 Locations and landing concepts study for further information.

Stage 1 of the study identified a total of five potential alignment options between Chelsea and Vauxhall bridges. These alignment options were identified principally based on the availability of bridge landing opportunities on the north and south banks of the river.

Figure 2: Alignment options

An initial options assessment was undertaken by the project team, and each option was scored against a range of key engineering and design aspects likely to affect the feasibility of constructing a new bridge in this location. These options are summarised below: Option 1

Nine Elms Riverside (US Embassy / Embassy Gardens) to Pimlico Gardens Option 1 scored highest in the initial options assessment. Adequate space exists on both sides of the river for landing points and the alignment has the potential to link into both existing communities on the north and those emerging on the southern side.

Option 2

Nine Elms Riverside to Pimlico Riverside (Dolphin Square) This option scored second highest. Adequate space exists for landing sites and the alignment has potential to maximise connectivity for nearby communities.

Options 3 & 3a

Nine Elms Pier to Grosvenor Road / Churchill Gardens Both options scored lowest in the initial options assessment, due primarily to insufficient landing space on both banks and were not progressed for further feasibility work.

7


Option 4

Battersea Power Station to Grosvenor Road (Grosvenor Rail Bridge) This option scored positively but was not initially progressed due to its location at the far west of the VNEB Opportunity Area. It was originally proposal that this structure be attached to the existing rail bridge, but Network Rail has indicated that any bridge would need to be structurally independent. Landing options are constrained by plans for nearby development and pre-existing buildings.

Options 1 and 2 were subsequently identified as the “most f easible”, and were progressed for further, more detailed feasibility work as the preferred options. Option 4 was identified as a cycleonly bridge, with the potential to be developed as a scheme in its own right at a later stage. However, this was considered as a complimentary measure rather than an alternative to the two preferred options.

4.2. Further options considered Since the initial options assessment was undertaken, three further alignment options have been identified by stakeholders. These further options are summarised below: Option 4a

Battersea Power Station to Grosvenor Road In recognition of the constraints associated with the bridge landings for Option 4, an alignment approximately 50m to the east of Grosvenor Railway Bridge has been proposed. Such an option could potentially serve to reduce the numbers of bridge users routeing through the Pimlico area.

Option 5

Nine Elms Riverside to Pimlico Gardens This option utilises the southern landing site of Op tion 2, and the northern landing site of Option 1. Due to its greater length and span, the cost and technical difficulty associated with Option 5 is greater than for other proposed alignments.

Option 6

Nine Elms Riverside to Grosvenor Road Option 6 utilises the southern landing site of Op tion 2, but its northern landing lies further east on Grosvenor Road. The high cost and technical difficulties associated with the Option 5 bridge also apply to Option 6.

Options 5 and 6 are not deemed to be feasible, and have not been taken for ward for further feasibility work. Option 4a has not been considered in d etail but could potentially be feasible. This option may be worthy of further feasibility work going forward. See Appendix B for further information on the advantages and disadvantages all of the alignment options considered, including the initial views of key stakeholders.

4.3. Focus of the feasibility study Stages 2 and 3 of the feasibility study have focussed on O ptions 1 and 2, and the majority of feasibility work has been completed on these options. Following requests from stakeholders, further consideration has also been given to Option 4, however this has been considered in less detail. The following sections of this summary report are therefore focused on a bridge in alignment option 1, 2 or 4.

5. Potential demand See Stage 2 Walk and Cycle Demand Analysis report for further information.

5.1. Walking and Cycling Demand Demand analysis suggests that there is a high potential demand for a bridge in the Option 1 alignment. Due to the close proximity of Option 1 and Option 2 similar levels of demand are expected at either location. Based on the results of this analysis, by 2031, when the development of the Opportunity Area is complete, the daily theoretical demand could be in the r egion of 9,000 pedestrians and 9,000 cyclists in total for both directions (i.e. both northbound and southbound trips). This is based on a number of assumptions, including that the new bridge will be at least as convenient to use as Chelsea and Vauxhall bridges, cyclists will be able to use the bridge without dismou nting at either side, the Mayor’s cycling targets will be met and the VNEB Opportunity Area will be developed in line with the plans outlined in the OAPF. This level of demand, if it were to be realised, would make a bridge in this location the 8 th highest used pedestrian crossing and the 6 th highest used cyclist crossing in London all other things remaining equal. This demand is expected to come mainly from trip diversion from Vauxhall and Chelsea bridges. In addition, there will be generation of new trips to and from the new jobs, homes and leisure opportunities that will be created in the Opportunity Area. The composition of demand is as follows:

Figure 3: Expected composition of demand

Trip diversion is expected to make up around two thirds of total demand for the new bridge. This is partly a reflection of the large distance between Chelsea and Vauxhall br idges (1.8km) relative to other central London bridges (600m average). This is supported by surveys of walking and cycling trip s across Vauxhall Bridge and Chelsea Bridge (carried out in late summer 2013), which suggest that a new bridge in the Option 1 alignment would be on the desire line of (and therefore potentially of 9


benefit to) a large number of existing users of Chelsea and Vauxhall bridges. The origin points of walking and cycling trips across these bridges, based on these surveys, can be seen in Appendix C. It should be noted that in practice the number users is not expected to match the theoretical demand. Given recent work into the engineering constraints which indicate that stairs and ramps are likely to be required to access the bridge deck (see Section 7), the level of usage will be lower, particularly for cyclists. Once information about the design of any new bridge is known, further work will be required to determine the impact that this design could have on level of use and the provision that should be made for cyclists. Nonetheless the fact remains that there does appear to be a high level of theoretical demand for a new bridge in this part of London. Demand for a bridge in the Option 4 alignment is likely to be significantly lower than Options 1 and 2 for walk and cycle trips. This is due to its position at the far western end of the VNEB OA and its greater distance from Vauxhall Bridge.

5.2. Accessibility A bridge in the Option 1 and 2 alignment would improve walk and cycle access between a number of popular destinations. From the new US Embassy in Nine Elms (currently under construction), for instance, Victoria Station and Westminster Cathedral could be reached on foot in around 20 minutes compared to around 30 minutes currently. The position of Option 4 at the western end of the Opportunity Area means that walk and cycle time to some destinations such as Pimlico station would be higher than in Options 1 and 2. However, an alignment in this location offers the opportunity to tie into future redevelopment of Victoria Railway Sidings, potentially benefitting from a direct link nort h through to Victoria Station in future.

5.3. Walk and Cycle Audit Should the bridge be implemented, a number of new trips will be generated and levels of walking and cycling close to the landing points in Pimlico and Nine Elms will increase. To assess current provision for walking and cycling in Pimlico on the north bank, where the neighbourhood is alr eady established, a walk and cycle audit was undertaken in the vicinity of the Option 1 and 2 landing points. Across the area the great majority of links most likely be used by pedestrians and cyclists are considered to be adequate for accommodating increased use. Appropriate opportunities for improving conditions have been identified, including through the provision of wayfinding and Legible London signage.

6. Planning issues 6.1. Consents See Stage 2 Initial Planning and Environment Assessment report for further information.

There are two planning consent routes available: the submission of two separate planning applications under the Town and Country Planning Act to Westminster City Council (WCC) and the London Borough of Wandsworth (LBW), or the submission of a Transport and Works Act Order (TWAO) to the Secretary of State for Transport. A TWAO would allow all necessary consents to be sought as part of the order, along with any necessary compulsory purchase powers, but the submission and decision process is likely be longer and more costly than a planning application. It is recommended that a Screening Opinion is sought to determine if the development would require a full Environmental Impact Assessment (EIA) or a comprehensive environmental report. A number of documents are likely to be required to support any submission, including a Planning, Design and Access Statement; Navigational Impact and Risk Assessment, and Flood Risk Assessment. Further discussion with the local planning authorities and other agencies ill be required to determine what further consents may be required, such as a Marine License (Marine Management Organisation), River Works License (PLA), Flood Defence Consent (EA) and Conservation Area Consent (Local Planning Authority).

6.2. Land Ownership The land ownership on the north and south banks for Options 1, 2 and 4 has been identified as follows: North bank freehold

South bank freehold

Option 1

City of Westminster

London Borough of Wandsworth and Elm Quay Freehold Limited

Option 2

Friends Life Limited

London Borough of Wandsworth and Elm Quay Freehold Limited

Option 4

Network Rail and Peabody Trust

Battersea Project Land Company Limited

Table 1: Land ownership

6.3. Heritage See Stage 2 Initial Heritage Assessment report for further information.

Option 1was assessed as having the greatest potential to enhance the local heritage given its alignment with St George’s Square on the north bank and far greater connectivity with Pimlico and Victoria than Option 2 which lands opposite the impenetrable Dolphin Square. Although there are a number of heritage and design issues to be addressed in both locations, the heritage assessment concludes that a sensitively designed, slender bridge could be a positive addition to the riverscape, enhancing this stretch of the Thames and opening up views to historic landmarks such as the power station, Vauxhall Bridge, Dolphin Square, and the 19 th century Pimlico townscape. Potential heritage impacts have not been assessed for Option 4.

11


6.4. Archaeology See Stage 2 Archaeological Assessment report for further information.

A desk based Archaeological Assessment concluded that there is potential for ar chaeological deposits to be present within both option sites, and r ecommends that investigation be undertaken to determine their presence (or otherwise). This would most likely be in the form of an archaeologist monitoring the geotechnical ground investigation works. If this shows the pr esence of - or a high potential for - archaeologically significant deposits, there may be a requirement for mitigation in the form of excavation prior to the start of construction or monitoring during groundworks.

6.5. Arboriculture See Stage 2 Arboricultural Assessment report for further information.

A Tree Report and Impact Assessment found high value trees located in close proximity to both options. It concludes that Option 2 is the most favourable terms of impact on trees, and with appropriate design should have a negligible impact. Option 1 would require far greater planning, design and implementation measure to avoid negative impacts on high-value trees at its north landing site in Pimlico Gardens. Due to changes in bridg e design since the initial tree report, it is recommended that further investigation be undertaken, including trial excavations at both locations to help confirm predicted impacts. An arboricultural assessment was not carried out for Option 4.

6.6. Ecology and Biodiversity See Stage 2 Initial Planning and Environmental Assessment report for further information.

The extent of in-river structures and the loss of inter-tidal habitats should be minimised under the proposed design, in keeping with other recent river cr ossing planning applications. Any loss of intertidal mudflats will have to be mitigated, either by like-f or-like replacement or financial compensation, and this mitigation will need to be agreed with the EA, Natural England (NE), the PLA and the MMO. It is recommended that further assessment is undertaken, including a desk based assessment and potentially marine and terrestrial surveys. Early discussions with the EA, MMO, PLA and NE are also recommended to help determine the extent of environmental assessment required.

12


7. Engineering issues See Stage 3 Engineering requirements report for further information.

In order to fully understand the engineering issues associated with constructing a new bridge in this reach of the River Thames, including the key constraints and parameters that need to be taken into account, various discussions with stakeholders and surveys have been undertaken. Two bridge concepts were developed also for the Option 1 and 2 alignments, partly to demonstrate how these constraints and parameters could potentially be addressed. A bridge concept design has not been developed for Option 4. These concepts – an arch structure for Option 1 and a cable stayed structure for Option 2 – were also used as a basis for obtaining advice on construction methodologies and estimating costs.

7.1. Concept designs Option 1: Arch Bridge A single tied arch, 152m bearings to bearings with suspended deck. This option requires two piers to be constructed in the inter-tidal zone, approximately 15m from the riverbanks.

Option 2: Cable Stayed Bridge Single large mast adjacent to South Bank with a cable supported deck. This option requires a single pier to be constructed in the river, approximately 60m from the south bank below mean low water spring level.

Figure 4: Designs for Option 1 (top) and Option 2 (bottom)

13


7.2. Stakeholder requirements See Stage 3 Engineering requirements report, Stakeholders and Consultation section, for further information.

Port of London Authority The PLA’s desirable navigation zone is 150m wide and 12.4m above Chart Datum (9.96m above ordnance datum). Bridge piers are permitted to be located outside of this zone. Consultation with the PLA is ongoing, including on the scope to reduce the 150m navigation zone and/or shift the navigation zone laterally north or south. The co nstruction programme for the bridge will also need to consider barge activity associated with the Northern line extension and Thames Tideway Tun nel (TTT).

Westminster Boating Base In order to enable Westminster Boating Base (WBB) to sail boats underneath the bridge at high tide, a 7m navigational clearance above Mean High Water Springs (10.91m above or dnance datum) is required. In terms of location, WBB’s first preference for Option 1 would be to move the pier south in line with the WBB pontoon and extend the pontoon to link with it, with a second preference to move the pier and extend the pontoon without physically linking them. Any linking of the pier and pontoon without moving the pier is felt not feasible. Both of these options require a reduction in the PLA’s 150m navigation zone. WBB’s third preference would be to extend the pontoon without relocating the pier. Relocating the buoys would be of no practical use to WBB. The only solution for Option 2 that would not affect WBB’s operations would be to have no intervention to the west of the base. Further consultation would be required with Westminster Boating Base to determine potential impacts should Option 4 be chosen as the preferred bridge location.

Cory Environmental Cory Environmental’s fixed barges would need to be r elocated to allow construction for Option 1. Further consultation will be required with Cory Environmental if the project moves forward

Thames Water Construction of the TTT is scheduled to occur from 2016 - 2020, and will require a large amount of spoil transported by barges in the same reach of the Thames as the proposed bridge. Constructing a bridge foundation above the TTT would incur significant cost. It is assumed that the foundations are to be outside the limits of deviation of the tunnel. It is likely that the detailed design of any new bridge will need to be approved by Thames Water.

Environment Agency The EA have expressed a preference for Option 4 due to its potentially lower impact on the river environment. However as long as a bridge at an alternative location did not unduly impact on the river environment, and appropriate environmental mitigation measures were included, it is likely that the EA be supportive overall given the sustainability benefits of walking and cycling.

7.3. Inclusive design See Stage 3 Engineering requirements report, Inclusive Design section, for further information.

The bridge must place users at the heart of its design process, adhering to the highest standards of accessible and inclusive design, and it is recommended that consultation with disabled people be used to inform the planning and design process. Segregation of shared facilities may be used to increase the sense of safety, user confidence and user comfort. Where practical, diff erent surface 14


textures should be used to aid visually impaired users on segregated footways. Surfaces should be firm, durable and slip resistant with consistent frictional characteristics. Visual contrast should be used to indicate level differences. Gradients should be as shallow as possible, preferably less than 1:21, on the bridge deck itself no steeper than 1:20 and on ramps no steeper than 1in 12. However, this means that flights lengths and traverse distances increase because of the added distance required. Lifts should be provided in pairs to ensure resilience. Lift sizes should be determined by traffic flow, with an initial minimum of Type III (1400 x 2000mm) lifts recommended pending further work.

7.4. People and cycle movement See Stage 3 Engineering requirements report, People and Cycle Movement section, for further information.

Bridge Width Based on the Stage 2 Demand Analysis bridge widths providing different levels of comfort have been considered. These widths exceed the minimum widths of shared paths as given in the Department for Transport Local Transport Note 2/86 ‘Shared Use by Cyclists and Pedestrians’. Total width

Table 2: Bridge widths considered

Bridge End Connections Three possibilities for the connection of the bridge to the existing infrastructure were proposed. Connection 1 provides a staircase and two lifts. The lifts have door s at

the front and back to allow easy through flow. The staircase is broken into flights which switch back onto themselves. It is estimated that a large percentage of cyclists would choose to use other bridges if faced with this option, and this was not adopted by the engineering requirements report.

Connection 2 also provides a staircase supported by two lifts. In this

scenario the staircase is linear, with wheeling ramps on each side running the full length of the stairs. This conenction may have a conflict at the top of the stairs should the cycle lanes be included in the middle of the bridge. This may need to be addressed with pavement marking/signage. This connection option was adopted by the engineering requirements report.

15


Connection 3 combines a staircase and lifts, with the opportunity

of including a ramp. It is assumed the most pedestrians and some cyclists would use the lift or stairs, with the remaining cyclists using the ramp. This has a lot more user resilience than connections 1 or 2, but due to the requirement for space it was not adopted by the engineering requirements report.

Lift and Stair Capacity The following table shows lift capacity and remaining demand using stairs/ramp, assuming that half of the lifts are used by pedestrians and the other half by cyclists. If the remaining demand was split equally between bridge ends this would give a cyclist headway of 3.5 seconds (feasible, although very congested) and a pedestrian headway of 12 seconds (a good level of comfort).

Further detailed analysis is required to confirm that the suggested capacities are adequate to meet demand. Further work could consider the predicted demand given different levels of comfort, the effect of wide stairs with large landings and the effect of escalators and mechanical wheeling ramps.

7.5. River & flood risk issues See Stage 3 Engineering requirements report, River and Flood Risk Issues section, for further information.

Flood Risk Management The EA expressed a preference for Option 4, as this would pose the least impact to flood risk. The EA’s preference is for one hydraulic efficient pier located on the north inside bend perpendicular to river flow. Surface run-off from the bridge deck should be discharged directly to the river, and a full flood risk assessment should be carried out to supp ort the bridge planning application. The bridge should allow for raising the existing river wall flood defences in line with the EA’s proposals under Thames Estuary 2100 (5.85m AOD by 2065, 6.35m AOD by 2100). It is recommended that the bridge pass over the flood defence wall at least 7.1m AOD for ease of future inspection and maintenance. The EA would support raising the height of the flood defences as part of the bridge works, and may propose a planning condition stipulating this.

Ecology & Environment The EA prefer Option 4, as it would pose the least threat to environment and ecology. The EA have requested that any pier(s) is located in the tidal zone, as the intertidal zone is the most ecologically rich part of the river bed. The EA will require mitigation for any loss of habitat. The EA’s favoured mitigation is the creation of tidal terraces, with timber fencing where tidal terracing is not appropriate. Light spill from the bridge should be limited and spill onto the river should be avoided. 16


Piling and dredging works during construction are likely to be carefully controlled and co nditioned by the EA.

It should be assumed that Notice is required for all temporary and permanent works within the river channel regardless of whether they are outside of the prescribed 150m navigation corridor.

Capital Dredge Consent

3 – 4 months

Required for all dredging works.

Marine License

No prescribed consenting period

1

A marine licence is required for any activities involving a deposit or removal of a substance or object below the mean high water springs mark or in any tidal river to the extent of the tidal influence.

Table 4: Approvals required for river works

This is not an exhaustive list and should continue to be reviewed. In addition to specific consents, licences and approvals for river works, there will be o ther requirements as part of the planning works, including Flood Risk Assessment, Water Framework Directive and Environmental Impact Assessment.

7.6. Geoenvironmental and Geotechnical Considerations See Stage 3 Engineering requirements report, Geoenvironmental and Geotechnical Considerations section, for further information.

The TTT will run under the southern side of the river with its tunnel crown at -35m OD. A services search must be commissioned that will confirm the location of all the services in the areas where foundation construction is to take place. Based on a Preliminary Risk Assessment, it was deemed unlikely that the site could meet criteria for Contaminated Land under Part 2A of the Environmental Protection Act 1990. The risk of encountering an UXO is considered to be moderate, and it is recommended that health and safety measures are put in place for the ground investigation and during its implementation.

Geotechnical Assessment The ground profile is typical for central London with the following notable differences: • • • •

1

Foundations remaining from historical development along the river banks Fluctuating groundwater table in the river banks Scour, or drift filled hollow to the south east side of the site area Thames Tideway Tunnel

st

st

Dredging works within the Thames are prohibited between 1 March and 31 October.

17


These could all have an effect on foundations for the bridge, and require focussed ground investigation and/or enabling groundworks.

Geoenvironmental Risk Assessment Potential risks to construction and maintenance workers are assessed as Moderate / Low. Appropriate Health and Safety precautions and personal protective equipment would provide reasonable mitigation. Potential risks to site users and off-site neighbours associated with the various contaminants are assessed as Moderate / Low. This reflects the nature of potential contaminant sources (Made Ground) and also the limited potential for exposure. This primarily relates to the accumulation of ground gas / vapours within enclosed spaces. Potential risks to groundwater are assessed as Low. This reflects the nature of potential contaminant sources, the shallow depth to groundwater but also the sensitivity of this receptor (Secondary Aquifers are in hydraulic continuity with the site, no hydraulic continuity with local public water supply abstractions due to presence of London Clay).

Proposed Ground Investigation Further ground investigation is recommended, with detailed recomm endations given in the Stage 3 Engineering requirements report, Section 8.7.

7.7. Surveys See Stage 3 Engineering requirements report, Surveys section, for further information.

A topographical survey was used to identify critical levels and constraints for Options 1 and 2. A utilities search was also carried out to check how utilities could affect the design and construction of the bridge. UK Power Network confirmed the location of a 132kV high voltage electricity tunnel under the Thames. This would form a potential constraint to the location of fo undations at the south end of Option 2.

PLA’s 150m navigation zone and EA’s desire for no pier(s) in the inter-tidal zone WBB’s preference for no pier on the north bank to the west of their buildings conflicts with EA’s desire for pier(s) to be on the north bank where possible WBB’s preference for no pier on the north bank to the west of their buildings combined with the southern location of the TTT make it difficult to provide PLA’s requested 150m navigation zone without constructing a single span structure The future working nature of Middle Wharf restricts the construction of a pier i n close proximity, which conflicts with WBB’s preference for no pier on the north bank to the west of their buildings unless constructing a single span structure

7.9. Landing and access See Stage 3 Engineering requirements report, Bridge Landing and Access Study section, for further information.

The need for a navigational ‘box’ of 150m x 10.91m AOD in order to meet PLA and WBB requirements results in a bridge deck approximately 6m above the adjacent ground level, given 1:21 ramping of the bridge deck ends. These constraints would result in long ramp s, leading to increased pressure on lifts. Ramps would have a large footprint and considerable visual impact. For the Option 1 and 2 southern landing sites, as well as Option 2 northern landing site, this may have an unacceptable impact on adjacent buildings and their views. Due to the height of the bridge deck, stairs of around 30 steps with a minimum width of 4m and a generous mid-level landing will be required. This represents a substantial structure. Cycle tracks integral to the stairs should be provided for cyclists, and cycle lifts or escalators could also be considered, subject to space requirements. A minimum of two lifts would be required to ensure resilience, and large non-standard lifts may be required. It is expected that pressure on lift space will largely come f rom cyclists.

21


7.10. Connection to local transport network See Stage 3 Engineering requirements report, Connection to Local Transport Network section, for further information.

North connection Cycle Superhighway 8 runs along Grosvenor Road providing a cycle link from all northern landing sites. To access this route eastwards from Option 2 landing site a new pedestrian and cycle (toucan) crossing opposite Dolphin Square will be required, although care will be required to ensure vehicular access to Dolphin Square is retained. An Option 4 landing south of Grosvenor Road will require a new toucan crossing, or enhancement of the existing junction with Lupus Street, in order to improve eastbound land connectivity. A landing in Victoria railway sidings would p rovide the opportunity to link into a potential future direct route throug h to Victoria Station following redevelopment of the sidings. However, site redevelopment plans are not certain and would not b e delivered until 2019 at the earliest. There are a number of possible methods for improving connections between Pimlico Gardens (Option 1) and existing walking and cycling networks. These include upgrading the existing pedestrian crossing to the west to accommodate cycles, an upgraded pedestrian crossing to the east, and a marked route eastwards from the landing site. A combination of these measures will avoid skewing cycle traffic in one direction.

South connection Established cycle lanes exist on both sides of Nine Elms Lane. The cycle lane on the north side of Nine Elms Lane follows the river bank for a length, which would allow it to connect directly with both the Option 1 and 2 landing sites. Full details of changes to cycling infrastructure as part of the ongoing OA development are not currently confirmed, but will be considered in any subsequent feasibility work. The Option 1 landing requires a new toucan crossing directly opposite. This will connect to emerging development and to the proposed cycle routes around New Covent Garden Market. The existing pedestrian crossing at Option 2 requires upgrading to a cycle crossing. Option 4 would land on a pedestrianised riverfront walkway, with quick onward connections to the proposed new Northern Line Station at Battersea Power Station.

7.11. Construction methodology See Stage 3 Engineering requirements report, Construction Methodology section, for further information.

This section of the study was developed in collaboration with Sir Robert McAlpine (SRM) and Severfield-Watson Structures Ltd (SWSL). Two principal design options for the bridge were considered. No construction methodology was developed for Option 4.

Materials Materials for Option 1could potentially be delivered to the r iverbank and then lifted into position by crane. Materials for Option 2 could potentially be delivered by barge and lifted into position by a crawler crane in initial work stages and then by a tower crane located on a dedicated platfor m.

22


Construction Access New road access will be created off Nine Elms Lane t o the east of Elm Quay Court visitor car park, which can be used to access both southern landing sites. The contractor will be required to prevent vehicles obstructing the private entrance and Nine Elms Lane ‘red route’. On the northern bank, new site access would be created off Grosvenor Road. The westbound slow lane could be closed off to allow entry and exit without interrupting traffic flow.

Recommendation Preliminary findings from SRM and SWSL conclude that from a construction perspective the cable stay design is preferred, as it involves less intervention in the river, it is technically simpler than the complex arched structure, there is a more man ageable weight of steel involved and it will require less temporary works.

23


8. Business Case and Costs The Outline Business Case compared the ‘Do Something’ scenario (a new pedestrian and cycle bridge is constructed) with a ‘Do Minimum’ scenario (a new bridge is not built but other developments in the VNEB area still come to fruition). This high-level business case attempts to d ocuments in a methodical way the expected benefits and costs of a new bridge, a nd is focused on the Option 1 alignment.

8.1. Costs See Stage 3 Engineering requirements report, Cost Model section, and Stage 3, Outline Business Case report, for further information.

The construction and whole life costs for Op tions 1 and 2 were estimated by Gardiner & Theobald, an independent cost consultant. No cost estimates have been produced for Option 4. Due to the relatively limited amount of design and specification information available at this stage, it is suggested that a confidence level of +/- 20% can be given to the costs relating to the bridge structures and +/- 30% to the costs relating to the landing arrangements (i.e. stairs and lifts). The estimated costs of the two options are similar (£38.4m and £40.5m respectively), and the costs for Option 1 have been used in the Outline Business Case. Note that whilst the Outline Business Case has not been updated to take into account the marginally different costs arising from the update of the Stage 3 Engineering requirements report in November 2014, the costs presented below in this summary report have been updated. The benefits considered would generally apply equally to Options 1 and 2, although there are differences between the two options in terms of costs and ot her feasibility / risk issues. The costs are in Q3 2013 prices, and are shown in the following table with and without an allowance for optimism bias: Q3 2013 prices, undiscounted, no optimism bi as added (£m)

Q3 2013 prices, undiscounted, with optimism bi as added to the capital costs (£m)

Table 8: Capital and operating costs

In undiscounted terms, the total costs are therefore £61.1m in 2013 prices. When the necessary adjustments have been made in order to make the costs suitable for inclusion within the economic appraisal, the total costs are £59.4m as a Present Value in 2013 p rices. In accordance with established guidance an allowance for optimism bias of 66% has been applied since this is a fixed link project where a single option is yet to be chosen. The capital costs exclude initial spares, land acquisition and demolition at life expiry. T he maintenance costs are presented in full in the Outline Business Case Section 3.5.

24


8.2. Results of Quantified Analysis See Stage 3 Outline Business Case report for further information.

In order to quantify the benefits of the new bridge, the 2031 trip diversion and trip generation rates from the Stage 2 Demand Assessment were used to estimate the profile of demand over time. F or the purpose of the economic appraisal the br idge is assumed to open in 2020. The following impacts of the bridge were quantified and valued: • • • • • •

Journey time savings; Safety; Ambience; Health; Vehicle operating cost savings; Emissions.

Results over the 60-year appraisal period are presented in the table below. The key assumptions used to quantify these impacts are presented in the Stage 3 Outline Business Case Section 3.9. Benefits

Benefit/Cost Ratio

Table 9: Benefits of the bridge over a 60 year appraisal period

The Benefit/Cost Ratio of 2.1:1 is above the TfL passmark of 1.5:1 and exceeds the 2.0:1 which Department for Transport WebTAG guidance suggests indicates of high value for money.

Limitations As noted above the business case is based on the maximum theoretical level of demand as set out in Section 5.1 of this report, which is unlikely to be achieved in practice given the likely requirement for stairs and lifts. For this reason the quan tified benefits are likely to be lower than those listed above; however initial sensitivity tests indicate that benefits would continue to outweigh costs even with conservative assumptions (eg. 50% scheme cost increase). Moreover, there are a number of significant benefits which have not been quantified at this stage such as t he bridge’s contribution to the image and regeneration of the VNEB Opportunity Area. It may be possible for some of these

25


additional benefits to be quantified once further info rmation about the timescales and location etc are known. Should further work on the scheme be undertaken, and a preferred option and design be agreed, there will be more certainty about the costs and it wi ll be possible to reduce the allowance for optimism bias to reflect this, which is likely to improve the case for the scheme. It may also be possible to develop a more economical structure than the concept designs completed for this feasibility study. One useful parallel is the proposed Diamond Jubilee footbridge, which would run adjacent to Battersea (Cremorne) Railway Bridge. This scheme has recently received planning consent. The forecast number of users is significantly lower than would likely be the case for a bridge in this location, yet the business case is still expected to be positive.

Measures of success It was suggested that the number of trips, journey time savings and accident savings should be adopted as the key measures of success, since these are the most important aspects of t he scheme in terms of quantified benefits.

26


9. Next Steps The feasibility study represents a foundation on which further, more detailed planning work can be based. Possible next steps could include:

Public consultation The undertaking of a public consultation would be a useful exercise for raising public awareness of the proposal and gauging opinion. It would allow interested stakeholders to express their views on the scheme which could inform various aspects of the scheme going forward. It may also assist in identifying a preferred location for the bridge.

Design competition A design competition could encourage design innovation and produce a range of bridge designs, and ultimately help to identify the optimum design for a structure befitting of this part of London. The findings of the Stage 3 engineering requirements report in particular report could be used to inform the competition brief. A certain level of certainty on funding is likely to be required before a design competition can be launched.

Changing the Capital’s landscape

Nine Elms on the South Bank will be a strikingly modern addition to the cityscape © IABSE

Nine Elms on the South Bank is being transformed into central London’s newest business, residential and leisure district. Under-used industrial land is making way for 16,000 new homes, parks, an embassy, schools, and enough commercial space to support 25,000 new jobs. It is the biggest regeneration programme in the UK.

MAYOR OF LONDON


The bridge would:  Transform cross-river connectivity in this part

of central London  Improve access to and from the 16,000 new

homes and 25,000 jobs being created at Nine Elms on the South Bank  Link existing communities in Pimlico and

the surrounding area to Nine Elms on the South Bank, including the new riverside walk and linear park, new shopping and leisure opportunities, Vauxhall, the new United States Embassy and a new town centre at Battersea Power Station  Encourage walking and cycling  Achieve an outstanding level of design

quality and underpin the regeneration of Nine Elms on the South Bank

An infrastructure investment package is supporting growth in the area and will provide a network of fast, high-capacity and sustainable transport links. A new pedestrian and cycle bridge across the river to Pimlico is a core element of this strategy. This project is now being led by Transport for London with support from Wandsworth and Lambeth Councils, and the Nine Elms Vauxhall Partnership. The bridge design must meet the high standards of the Pimlico Conservation Area on the north bank, and the developing public realm and landscape schemes on the south bank. As well as creating a vital new pedestrian and cycle link between these two areas, the bridge should be an exceptional addition to Thames architecture that communities on both sides of the river can be proud of.

MAYOR OF LONDON


Wider transport package

Next steps

The potential bridge crossing is accompanied by many other transport and urban realm improvements that form a comprehensive transport strategy for Nine Elms on the South Bank. They include an extension of the Northern line to Battersea with two new Tube stations, enhanced bus services, improvements to National Rail stations, new passenger piers at Vauxhall and Battersea Power Station, pedestrian and cycle walkways, and new Barclays Cycle Hire docking stations.

The optimum location for a new bridge is currently being investigated. Next steps could include:  Further assessment of locations  Public consultation to decide on a preferred location  Launch of a design competition
