The Gamuda Australia and Laing O’Rourke consortium has been awarded a AUD 2.16 billion (USD 1.57 billion) contract to deliver the next stage of tunnelling on the Sydney Metro West project.
The consortium will perform West tunnelling contract to deliver 9 km of twin metro rail tunnels between Sydney Olympic Park and Westmead.
The contract includes:
- Twin 9 km tunnels from Sydney Olympic Park to Westmead;
- A TBM launch site at Rosehill, tunnelling toward Sydney Olympic Park and relaunched toward Westmead;
- A services facility and crossover structure at Rosehill for fresh air ventilation and emergency egress;
- Tunnel portal and dive excavation at Clyde services and maintenance facility;
- Earthworks, retaining structures, drainage and utilities corridor for the Clyde maintenance facility;
- Two spur tunnels connecting the dive structure to the Main tunnel in at Clyde;
- Excavation and civil works for Parramatta and Westmead Stations; and
- A segment manufacturing facility at Eastern Creek.
The contract is expected to be completed by the end of 2025.
This is the second major tunnelling package awarded on the city’s metro project, with work already underway to deliver twin tunnels between The Bays and Sydney Olympic Park following the contract awarded to Acciona Ferrovial joint venture last year.
Major civil works have started at The Bays, with tunnelling set to begin later this year towards Sydney Olympic Park. Work is well underway to get the site ready for tunnel boring machines and piling rigs have started work to prepare the site for the excavation needed to launch the mega machines.
Sydney Metro West is a new 24-km metro line with the 9 stations confirmed at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays, Pyrmont and Hunter Street in the Sydney CBD.
