City Rail Link Ltd announced the preferred bidder for Auckland City Rail Link C3 Contract, envisaging the construction of the underground tunnels and stations.
The Link Alliance (Vinci Construction Grands Projet, Downer NZ, Soletanche Bachy International NZ, WSP Opus (NZ), Aecom New Zealand and Tonkin + Taylor) was selected to perform the C3 contract, which is the project’s largest package of work.
C3 includes construction of twin rail tunnels, construction of two underground stations and rebuilding Mt Eden station. The City Rail Link is the largest infrastructure project undertaken in New Zealand.
The contract is expected to be signed in May.
Progress on the project will still continue as CRL Ltd starts negotiations with the Link Alliance to deliver the AUD 75 million (USD 54 million) early works contract over a three-month period. The contract includes work relating to design, consents, permitting, utilities and mobilisation.
For this contract, a consortium formed by CPB Contractors Pty Limited, UGL (NZ) Limited, Beca Limited, Jacobs New Zealand Limited and McMillen Jacobs Limited submitted its offer at the competitive tender process.
City Rail Link Ltd has also announced a revised cost envelope for completing the entire Auckland City Rail Link project totalling AUD 4.4 billion (USD 3.18 billion), a AUD 1 billion (USD 720 million) cost increase.
“The const increased on the previous AUD 3.4 billion estimate made in 2014 reflects significant changes impacting the project in the past five years,” CRL Ltd’s Chief Executive, Sean Sweeney, said.
City Rail Link is a 3.45 km twin-tunnel underground rail link up to 42 metres below the city centre transforming the downtown Britomart Transport Centre into a two-way through-station that better connects the Auckland rail network.
When completed, in 2024, the CRL will improve travel options and journey times and double the number of Aucklanders within 30 minutes travel of the CBD.
CRL allows the rail network to at least double rail capacity. New rail transport growth statistics suggest that by 2035, CRL stations will need to cope with 54,000 passengers an hour at peak travel times, rather than the original estimate of 36,000.
