The New South Wales Government has awarded a $2.16 billion contract to deliver the next stage of tunnelling on the mega Sydney Metro West project.
The Gamuda Australia and Laing O’Rourke consortium has been awarded the Western Tunnelling contract to deliver 9 km of twin metro rail tunnels between Sydney Olympic Park and Westmead.
Premier Dominic Perrottet said this once-in-a-century infrastructure investment will link new communities to rail services, slash travel times across the network and support employment growth.
“These tunnels mean you’ll be able to get from Parramatta to the Sydney CBD in around 20 minutes on a fast, safe and reliable driverless metro train, forever changing how we move around Sydney,” the Premier said.
“Sydney Metro West will double rail capacity between Greater Parramatta and the Sydney CBD, transforming Sydney for generations to come.”
This is the second major tunnelling package awarded on the city-shaping 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.
According to the Minister for Transport David Elliot, work is well underway in readying the site for the arrival of the tunnel boring machines (TBM) at the end of the year.
“Huge piling rigs have already started work to prepare the site for the excavation needed to launch the mega machines,” Minister Elliott said.
Alongside the 9 km twin tunnels, the contract also includes a TBM launch site at Rosehill; a service facility and crossover structure; tunnel portal and dive excavation; earthworks, and more.
The NSW Government said completion of the contract is expected by the end of 2025.
