John Holland has been awarded the contract to tunnel underneath Sydney Harbour as part of the AU$2.81 billion Sydney Metro project.
The Sydney Metro City & Southwest Tunnel and Station Excavation Works (TSE) contract includes the construction of twin 15.5 km tunnels and civil works for six new metro stations with John Holland’s joint venture (JV) partners: CPB Contractors and Ghella.
The JV was recognised with several awards after it completed the first stage of the project last year, building two 15 km tunnels from Bella Vista to Epping.
Five tunnel boring machines (TBMs) will be utilised for tunnelling between Chatswood and Sydenham, including a specialised TBM to bore beneath Sydney Harbour.
The new stations will be built at Crows Nest, Victoria Cross, Barangaroo, Martin Place, Pitt Street and Waterloo.
“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,” said John Holland CEO Joe Barr.
“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,” he said.
“We have recently delivered the Sydney Metro Northwest Tunnels and Station Civil Works contract and are currently working on the Operations, Trains and Systems contract,” said Executive General Manager NSW/ACT Scott Olsen.
“We bring vast local and international expertise in tunnelling and the delivery of major infrastructure in urban areas.
“We are focused on delivering a world-class project in partnership with Transport for NSW, with sustainable design, opportunities for local employment and a socially inclusive procurement strategy.”
Construction is scheduled to commence in the coming weeks, with the contract expected to be completed in 2021.
