Infrastructure and environment consultancy WSP Opus has been selected by City Rail Link as the design partner on the C7 workstream of the City Rail Link (CRL) project in Auckland, New Zealand.
WSP Opus has formed a joint venture – Systems Integration, Testing and Commissioning (SITC) Alliance – with engineering and infrastructure company RCR Tomlinson, to carry out project work on the C7 Rail Project.
The Auckland City Rail Link is the largest infrastructure project to be taken up in New Zealand, which is expected to transform Auckland.
The NZ$3.4bn ($2.2bn) CRL project is divided into a series of workstreams and key operational activities comprising nine construction contracts (C1 to C9).
WSP Opus is currently involved in C2 (Albert St trench) and C6 (Mt Eden Stormwater relocation).
Work is expected to commence in June 2019 and be delivered over 4.5 years. The overall project is due for completion in 2024.
The CRL is jointly funded by the New Zealand government and Auckland Council and has full governance, operational and financial responsibility for the delivery of the project in accordance with its objectives.
The project consists of a 3.45km twin-tunnel underground rail link up to 42m below the city centre, transforming the downtown Britomart Transport Centre into a two-way through-station that connects the Auckland rail network.
RCR Tomlinson, along with Opus International Consultants (in joint venture as SITC), has entered into an Interim Project Alliance Agreement with CRL.
Under the agreement, SITC will work in collaboration with City Rail Link, Auckland Transport and Kiwi Rail to develop an alliance proposal for the C7 Rail Project.
If SITC’s proposal is accepted, SITC will enter into a Project Alliance Agreement with City Rail Link and Kiwi Rail for the construction alliance phase.
The C7 Rail Project will include the provision of track, track slab, overhead line, signalling, control systems, communications systems, trackside auxiliaries, control room fit-out and building works.
Rail systems will be installed, tested and commissioned from the existing operational railway to the east of Britomart, through Britomart Station, the new station and tunnels, and to the Western Line.
