Australia's New South Wales (NSW) Government has invited tenders to apply for a contract to build a pair of metro tunnels under Sydney Harbour.
Consortia invited to bid for the works include Ferrovial, Acciona and BAM Joint Venture, and John Holland, CPB and Ghella Joint Venture.
The contract is expected to be awarded around mid-2017.
Once awarded, the consortium will undertake the tunnelling and station excavations for Sydney Metro City & Southwest project. Tunnelling will stretch from Chatswood, under Sydney Harbour and across CBD.
New South Wales transport and infrastructure minister Andrew Constance said: “We’re cracking on with delivering this mega project for Sydney and the hive of construction activity is continuing in the north-west.
“The frame of the first platform is in place at Cudgegong Road, one of 31 metro stations along the 65km route.”
NSW said that construction for the first station platform of the new metro rail project at Cudgegong Road has also started.
With a length of 187m and width of 9m, the Cudgegong Road station platform have peak-service frequency of a train every four minutes. The station will also feature around 1,000 car parking spaces.
Constance added: “When Sydney Metro is extended into the CBD and beyond in 2024, there will be ultimate capacity for a metro train every two minutes in each direction under the city.”
The Sydney Metro City & Southwest project comprises seven new modern metro stations, which will be completely accessible for disabled passengers and those with prams. The development will feature level access between platforms and trains.
