SYDNEY Metro has awarded a joint venture between John Holland, CPB Contractors (CPB) and Ghella a $A 1.63bn ($US 1.1bn) contract for the final stage of tunnelling on the Sydney Metro West project.
Sydney Metro West is a new 24km metro line with stations at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays, Pyrmont and Hunter Street in the Sydney city centre.
The Eastern Tunnelling contract is the third and final major tunnelling package, and includes works to deliver 3.5km of metro rail tunnels between The Bays and Hunter Street. The contract also includes a turnback cavern to the east of the new Hunter Street Station, allowing trains to turn around before travelling back towards Parramatta.
Preparations for tunnelling on this final section of the line will start next year.
Work is already under way to prepare for construction of the twin tunnels between The Bays and Sydney Olympic Park, and between Sydney Olympic Park and Westmead. Tunnel boring machines are expected to start work in early 2023. The full Sydney Metro West line is on track to be completed in 2030.
Transport for New South Wales (NSW) announced a new contracting model for the Sydney Metro West project last month.
