Three Shortlisted for $4.6 billion Melbourne Metro

melbourne-metroThree consortia featuring the world’s best construction companies have been shortlisted for the $6 billion ($4.6 billion US) public-private partnership (PPP) to build the Metro Tunnel, the Melbourne Metro Rail Authority announced Aug. 10.

The shortlisted bidders are:

  • Continuum Victoria – comprising ACCIONA Infrastructure, Ferrovial Agroman, Honeywell, Downer EDI and Plenary Origination
  • Cross Yarra Partnership – comprising Lendlease Engineering, John Holland, Bouygues Construction and Capella Capital
  • Moving Melbourne Together – comprising Pacific Partnerships, CPB Contractors, Ghella, Salini Impregilo, Serco and Macquarie Capital

The PPP will build and fit-out the 9-km Metro Tunnel and the five new underground stations at Arden, Parkville, CBD North, CBD South and Domain.

Up to six tunnel boring machines (TBMs) are set to be used during construction, each up to 100 m long and weighing more than 1,000 tonnes.

In preparation for this significant work, three shafts will be excavated in the CBD – at  Franklin Street and A’Beckett Street near Melbourne Central station, and at City Square near Flinders Street Station.

The shafts will be up to 11 stories deep and will enable the roadheaders to be lowered into the ground to begin excavating around 2 million cubic meters of soil and rock – enough to fill 800 Olympic-sized swimming pools.

Shortlisted bidders for the PPP will be asked 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 PPP will begin in 2018.
