Link Alliance, a consortium led by Vinci Construction, has secured two design-build contracts about €485m for the €2.5bn City Rail Link (CRL) line project in Auckland, New Zealand.

The consortium includes Vinci Construction’s subsidiaries Vinci Construction Grands Projets and Soletanche Bachy International and other partners including Downer, WSP-Opus, AECOM and Tonkin & Taylor.

Under the first contract, which is for the Package 5 of the CRL project, the Link Alliance will be responsible for the construction of two structures (grade-separated junctions) and 2km of new track while maintaining traffic on the North Auckland Line.

The second contract is for the Package 7 of the project, which involves installation of power supply, overhead lines, signalling and the control system for the entire Auckland City Rail Link project.

The contract for Packages 5 and 7 follows the contract awarded for the Package 3 in July last year to the same consortium.

The Package 3 involved design and construction of a 3.45km of extension of a railway line, including 3.2km of tunnel to connect the existing Britomart station to the existing Mount Eden station and three new stations.

Vinci Construction said that the contracts are of the Alliance type that combines the designer-builder consortium and the client, City Rail Link, to create a single team to deliver all three Packages 3, 5 and 7 in 2024.

The CRL line project is said to double the rail capacity. It can accommodate approximately 54,000 passengers per hour during peak hours, which is equivalent to the capacity of two motorways with four lanes in each direction.
