Laing O'Rourke will be upgrading Central Station and the contract includes:
- the excavation and construction of the new underground Sydney Metro platforms at Central beneath platforms 13 and 14;
- Central Walk - a new 19-metre wide underground concourse from Chalmers Street, connecting customers to suburban rail platforms, Sydney Metro platforms, the new light rail and buses; and
- escalators linking platforms 12 to 23.
Completion of the Central Walk and Central Station metro upgrade contract is expected in 2022, with Central Walk open to customers.
Due to the massive scale of the Sydney Metro project, the final Central contract value may vary due to ongoing fine-tuning and optimisation involving the 14 other major contracts, for which tenders have yet to be received.
The first of five mega tunnel boring machine will be in the ground before the end of this year to deliver the twin 15.5km metro rail tunnels between Chatswood and Sydenham.
Once the Central contract is complete, work will continue along the 30km length of the Sydney Metro City & Southwest project to lay tracks and fit out stations before services start in 2024.
