City Rail Link



City Rail Link is committed to a robust and transparent procurement process focused on risk management, value and ensuring a fair and equitable outcome.

Alliance preferred bidder announced

News release - 17 April 2019

City Rail Link Ltd (CRL Ltd) today announced a revised cost envelope for completing the entire Auckland City Rail Link project totalling $4.419 billion, alongside naming its preferred bidder for its substantive C3 Contract to build the underground tunnels and stations and a $75 million Early Works Contract.

CRL Ltd’s Chief Executive, Dr Sean Sweeney, says after a rigorous and comprehensive review of project costs, a revised cost envelope has been submitted to the project’s sponsors – the Crown and Auckland Council - for approval.

“The $1 billion cost increase on the previous $3.4 billion estimate made in 2014 reflects significant changes impacting the project in the past five years,” says Dr Sweeney.

 “No-one could have foreseen the competitive pressures that have occurred in the construction industry over the past few years and the impact that has on costs, particularly for a project the scale and complexity of the City Rail Link.

“Eighteen months ago, the value of work in the infrastructure pipeline on both sides of the Tasman was $80 billion – the value of that work is now estimated at $230 billion.

“Last year, a decision was made to increase the scope of the project to accommodate longer, nine-car trains at stations. Planning today for a city that will be much bigger in the future reinforces the benefits the City Rail Link City will deliver to the way people travel, work and live in Auckland.

Other factors contributing to the revised cost envelope are higher escalation, or construction inflation costs, and an increase in the contingency risk allowance for any future unplanned events.

“Put together, they have all helped add costs to the project overall. Keeping a growing city moving is a serious challenge, but when we complete the City Rail Link it will double the number of Aucklanders within 30 minutes travel of the CBD.”

Dr Sweeney says CRL Ltd’s own cost review underwent a rigorous examination by two international assessors to ensure the project delivers the best value for money for Aucklanders.

Decisions by the Crown and Auckland Council regarding their endorsement of the revised cost envelope are expected in early May.

After an exhaustive competitive tender process, the Link Alliance (Vinci Construction Grands Projet S.A.S,, Downer NZ Ltd, Soletanche Bachy International NZ Limited, WSP Opus (NZ) Limited, AECOM New Zealand Limited and Tonkin + Taylor Limited) has been announced as the preferred bidder for the C3 contract – the project’s largest package of work.

The Link Alliance was one of two groups of New Zealand and international infrastructure companies that submitted what Dr Sweeney, describes as “world class and competitive bids” for the contract. The other group was a consortium of: CPB Contractors Pty Limited, UGL (NZ) Limited, Beca Limited, Jacobs New Zealand Limited and McMillen Jacobs Limited.

Dr Sweeney says that both these joint-ventures consists of outstanding contractors with a wealth of experience delivering major project both here an overseas.

“The calibre of both the tenders were exceptional. Aucklanders can be confident that the project will be delivered to a high standard leaving behind an outstanding legacy for the city,” he says.

Dr Sweeney says progress on the project will still continue at pace as CRL Ltd starts negotiations with the Link Alliance to deliver the $75 million Early Works Contract over a three-month period. The contract includes work relating to design, consents, permitting, utilities and mobilisation.

“The project is already well underway at Lower Queen Street/Britomart, Albert Street and Mt Eden, and momentum will continue. CRL Ltd will now work with the preferred bidder to get the Early Works Contract underway as quickly as possible. 

“This keeps us on track to have this transformational project in place and delivering significant benefits for Aucklanders at the end of 2024.

“Today’s announcements represent huge step forwards for a project that will create accessibility and development opportunities that will allow Auckland to remodel itself as a city that is proudly international,” Dr Sweeney says.

Alliance news release - 20 December 2018:

CRL moves to single Alliance to deliver stations, tunnels and rail systems

City Rail Link Ltd (CRLL) today announced that it intends to proceed with a single Alliance to deliver the stations, tunnels and rail systems – including the C7 Rail Systems Contract.

CRLL Chief Executive Dr Sean Sweeney says that a single alliance will deliver positive outcomes and significant opportunities for the project.

The decision follows the announcement that RCR Tomlinson and more recently RCR infrastructure (NZ) had gone into voluntary administration. RCR Infrastructure (NZ) Ltd forms part of the Systems Alliance (C7 consortium) that has been awarded the Interim Project Alliance Agreement (IPAA) that is currently delivering the design for the C7 Systems Contract.

“We were notified on 21 November that RCR Tomlinson was in voluntary administration with administrators undertaking a trade sale of profitable parts of the business – including RCR Infrastructure NZ. Since then we have worked hard to understand the impacts on the project and identify the best way forward to complete the C7 works.

“We have determined that the best-possible response is for the current C7 consortium to continue to deliver the design elements for the C7 systems. However, they will no longer submit a tender for the C7 construction works which will instead be incorporated into the C3 Main Station and Tunnels Alliance -  due to start construction mid-next year.

The C3 contract is currently in the final stages of a tender process with two shortlisted tenderers, the Link Joint Venture with Downer, Vinci Grands Projets, Soletanche Bachy, AECOM, Tonkin and Taylor and WSP Opus and a joint venture between CPB Contractors, UGL, Beca, McMillen Jacobs Associates.

The contract is expected to be awarded by the end of April next year and the successful tenderer will now deliver the stations, tunnels and the rail systems for the City Rail Link project.

Dr Sweeney says that delivering City Rail Link on schedule is a key priority and was a critical factor in deciding to go with a single Alliance. He adds that delivering the works as a single Alliance will deliver many benefits for the project.

“By shifting to a single Alliance model now we are ensuring no time lost on the procurement programme as a result of the RCR administration process. It also removes the need for major interface coordination which means less risk and it reduces demands on resources across our delivery partners.”

Dr Sweeney says that the C7 Consortium will continue to complete the design work which is likely to be finished by March next year.

Contract 7

The Interim Project Alliance Agreement (IPAA) for the delivery of the project’s underground rail systems (C7) has been awarded to a joint venture between RCR Infrastructure (NZ) Ltd and its design partners WSP Opus – together known as the Systems Integration, Testing and Commissioning (SITC) Alliance. Details here.

Update: Statement from CRL Ltd re RCR Tomlinson Administration - 23 Nov 2018 

  • RCR Infrastructure (NZ) Ltd is in joint venture with WSP Opus to deliver a design solution for the C7 rail systems contract.

  • The C7 rail systems contract is one of seven contracts that will be building the City Rail Link (CRL). See the Procurement section for details.

  • The contract has a current value of $7.5m.

  • The joint venture currently has 75% staffed by WSP Opus.

  • RCR Infrastructure (NZ) Ltd - a party the CRLL is in contract with - is not in administration and is still trading.

  • Work has not stopped on the on the C7 design.

  • CRLL met with the New Zealand agent of the administrators (acting in relation of the voluntary administration of the Australian entity) today to discuss the ramifications of the RCR administration on the RCR Infrastructure (NZ) Ltd. The administrator’s current position is that they are working to secure further working capital from the existing banking syndicate to enable a quick robust process to determine the value of the profitable parts of the business.

  • As is prudent, CRLL continues to evaluate a range of options.

Update: Further Statement from CRL Ltd re RCR Tomlinson Administration - 18 December 2018

City Rail Link is aware that RCR Infrastructure NZ has been placed into voluntary administration.

This has no impact on the work that is currently being undertaken as part of the Interim Project Alliance Agreement to deliver the design for the project’s C7 contract.

RCR Infrastructure NZ forms part of that Alliance together with WSP Opus and other parties.

That design work is continuing and is expected to be complete in March next year.

City Rail Link is being prudent and is planning for a number of contingencies with regards to delivering the construction of the C7 contract.

Work Package descriptions

C5 Western Line

The C5 Work Package has been amended to include only the civil elements of the Western Line, with the C7 Work Package now undertaking the rail systems elements. The contract model for the C5 Work Package is still being determined.

The work includes civils works required to connect the CRL main tunnels to the Western Line and comprise significant civil construction works with new road, rail and pedestrian bridges and retaining walls.

C6 Mt Eden Stormwater Relocation

C6 has been procured as a lump sum, construct only contract using the NZS 3910 form of contract and has been awarded to March/Bessac JV.

The C6 Work Package includes the construction of a 1.95m diameter pipeline at depth below ground level replacing the existing pipeline length on a new alignment over approximately 420m between Water Street carpark and Ruru/Nikau street intersection in Mount Eden. The key elements of the C6 Work Package include:

  • boring and thrusting a new pipeline at depth on curved lines through a wide range of material with accurate level tolerances

  • demolition of two buildings

  • excavation and construction of three permanent access shafts at Water Street, Ruru/Nikau Street and Mt Eden Road

  • joining of the new pipeline to the existing pipeline by cutting-in at both ends

  • minor utility relocations, vehicle access and retaining wall construction and relocating an overhead traction power gantry on the rail corridor

C7 Systems, Integration, Testing and Commissioning (Rail Systems Alliance)

C7 will be procured using an Alliance form of contract and will be a linewide rail systems package.

Works include provision of trackslab, track, overhead line, signalling (control software and systems and interlockings to be provided by CRLL), control systems, communications systems, control room fit-out and building work, and trackside auxiliaries. Rail systems to be installed from the existing operational railway to the east of Britomart, through Britomart Station, C1, C2 and DSC, the new station and tunnels (C3), and the Western Line (C5).

Works also include responsibility for Operational Readiness. Once construction work has been completed and individual systems have been tested and commissioned, the system needs to be commissioned into service. This will include a trial running period, equipment testing and commissioning, driver training, test train running and operating/maintenance manual updating. Key stakeholders will include construction contractors, the train operator (currently Transdev), KiwiRail as owner and network operator, AT and CAF (the train supplier).

The C7 Work Package now also includes the scope of the previous Britomart East C9 Work Package to provide increased vertical pedestrian/passenger flows out of the east end of Britomart, as well as the scope of the Henderson and Newmarket sites.

C8 Wider Network Improvements (Otahuhu and Strand)

The scope of the C8 Work Package has been reduced to cover the Otahuhu and Strand sites. The works at Henderson and Newmarket have been re-allocated to the C7 Work Package. The C8 Work Package will now be delivered by KiwiRail and Auckland Transport.

The scope of the C8 Work Package includes:

Otahuhu Station rearrangement – introduction of the CRL timetable diverts many Western Line services away from Newmarket and South to give the significantly better West to Britomart service. A new service will be provided between Henderson and Otahuhu as a replacement. This project allows the operations of the purple route at Otahuhu.

Strand Crossover – The CRL timetable demands efficiency of all movements and the movements out of the Strand EMU storage depot are inefficient due to the extensive amount of ‘wrong way running’. This is resolved by the placement of this crossover. 

C9 Britomart East

The scope of works for this package has been re-allocated to C7.
