The Gamuda Australia and Laing O’Rourke consortium has been contracted to execute the upcoming stage of tunnelling for the Sydney Metro West project.

The value of this tunnelling contract stands at $1.57bn (A$2.16bn).

Under this Western Tunnelling contract, the consortium will work on establishing twin metro rail tunnels, which will span 9km, between Sydney Olympic Park and Westmead.

This contract involves building 11km of twin metro rail tunnels from Sydney Olympic Park to The Bays, with work already making progress.

Civil works have now commenced at The Bays, with tunnelling set to start later this year towards Sydney Olympic Park.
