CIMIC Group’s CPB Contractors, in joint venture with Ghella, has been selected by the NSW Government to deliver the Sydney Metro – Western Sydney Airport Station Boxes and Tunnelling Works (WSA-SBT).
The first of four mega tunnel boring machines will be in the ground by early 2023 to deliver 9.8 kilometres of twin metro rail tunnels in two sections, under the first major contract to be awarded as part of the project.
The driverless 23-kilometre metro line will link St Marys to the centre of the new Aerotropolis via the new Western Sydney International (Nancy-Bird Walton) Airport, with six stations to be built along the alignment.
The Station Boxes and Tunnelling contract includes:
- 9.8 kilometres of twin rail tunnels in two sections. The 4.3-kilometre northern tunnels run from St Marys to Orchard Hills and the 5.5-kilometre southern section of tunnels runs between the Airport Business Park and the Aerotropolis Station;
- Excavation and civil works for new stations at St Marys, Orchard Hills, Western Sydney International (Nancy-Bird Walton) Airport, and Aerotropolis;
- Four hard rock Tunnel Boring Machines (TBM);
- Building one of the two temporary precast concrete factories for the project on the Western Sydney International site;
- More than 67,000 concrete segments to line the twin tunnels;
- Two TBM launch sites at Orchard Hills and Western Sydney International and two TBM retrieval sites at St Marys and Aerotropolis Station.
Once the tunnelling contract is complete in late 2024, work will continue to lay tracks and fit out stations.
The Australian and NSW governments are joint funding the Sydney Metro – Western Sydney Airport metro line project on a 50:50 basis.
The $1.8 billion contract will generate revenue of approximately $1.35 billion to CPB Contractors.
“The new Sydney Metro – Western Sydney Airport metro line will support 14,000 direct new jobs and drive major economic stimulus for Western Sydney.
“The tunnelling contract will require a broad range of skills including specialist tunnellers, electricians, plumbers, carpenters, concrete workers, truck drivers, labourers and security guards,” said NSW Minister for Jobs, Investment, Tourism and Western Sydney, Minister for Trade and Industry, and State Member for Penrith the Hon Stuart Ayres MP.
CPB Contractors Managing Director Jason Spears said: “We are pleased to have been selected by the NSW Government to deliver another vital project for Western Sydney. Our tunnelling teams are very experienced in delivering transport infrastructure in Sydney and will apply CPB Contractors’ expertise, gained delivering major projects across Australia, to maximise employment and training opportunities for local workers.”
