The joint venture of John Holland, CPB Contractors and Ghella has won the contract to deliver the new $2.81 billion Sydney Metro City & Southwest Tunnel and Station Excavation Works (TSE).
The twin tunnels will be excavated by five tunnel boring machines (TBMs) between Chatwood and Sydenham, including a specialised TBM to construct the tunnels beneath Sydney Harbour.
The new stations will be built at Crows Nest, Victoria Cross, Barangaroo, Martin Place, Pitt Street and Waterloo.
John Holland Chief Executive Officer, Joe Barr, said it would be an honour to deliver Australia’s largest public transport project, which will revolutionise public transport in Sydney.
“This iconic project will build the first ever rail tunnels under Sydney Harbour – a crucial transport connection to meet the ever growing needs of our global city,” he said.
“This one-in-a-generation project will transform the rail network in Sydney, delivering a step-change in public transport capacity and customer experience, and it is a privilege to be trusted to build it.
“Our construction solution addresses the challenges of intricate underground construction in the heart of the Sydney CBD. We will use barges on Sydney Harbour to help minimise impacts on the road network at the Barangaroo and Blues Point work sites.”
Construction is scheduled to commence on the TSE Works in the coming weeks, with the contract expected to be completed in 2021.
