Three consortia have been shortlisted for the construction of the tunnel and underground stations that form part of the A$10.9 billion ($8.36 billion; €7.43 billion) Melbourne Metro PPP.
The selected bidders include the Continuum Victoria, comprising Acciona Infrastructure, Ferrovial Agroman, Honeywell, Downer Edi and Plenary Origination; and the Cross Yarra Partnership, composed of Lendlease Engineering, John Holland, Bouygues Construction and Capella Capital. The third bidder, Moving Melbourne Together, comprises Pacific Partnerships, CPB Contractors, Ghella, Salini Impregilo, Serco and Macquarie Capital.
The project, which has an expected cost of A$6 billion, calls for the construction and fit-out of the 9km Metro Tunnel and five new underground stations at Arden, Parkville, CBD South and Domain.
Shortlisted bidders for the PPP will need to submit a formal proposal by early next year, with a contract expected to be awarded by the end of 2017. Work on the Tunnel and stations will begin in 2018.
The project is the largest bundle among a series of packages for the construction works of Melbourne Metro PPP. The new Metro Tunnel will allow more trains run in and out of the city by giving three lines their own tunnel through the CBD.
This June, the A$324 million early-work package, the first of the series, was awarded to John Holland, which will undertake the excavation of huge open shafts in the centre of Melbourne to enable underground construction. Other works in the package include the relocation and protection of up to 100 utilities, including gas, power and telecommunications services, and the 120-year-old main sewer line under Domain interchange. The work on the station shafts will begin next year.
