Australian tunnelling project names winning consortium

Australia’s Victorian state government has revealed the joint venture (JV) that has been selected to build the Melbourne Metro Tunnel.

Earlier this month in Victorian Premier Daniel Andrews and Minister for Public Transport Jacinta Allan announced that the Cross Yara Partnership (CYP) – a JV comprising Lendlease EngineeringJohn HollandBouygues Construction and Capella Capital – had been awarded the most significant contract on the AU$6 billion (US$4.81 billion) project.

The CYP will be responsible for building and fitting out the 9 km tunnel, as well as the construction of five new underground stations in Melbourne, including two in Melbourne’s CBD and one at a major Melbourne tram interchange.

Up to six tunnel boring machines (TBMs) could be used during construction, each up to 100 m long and weighing more than 1,000 t.

“We’re building the turn-up and go train system Victoria has been waiting for,” said Premier Daniel Andrews.

“We’ve chosen the design, we’ve chosen the builders and we’re getting on with it.

“We don’t just talk about it – we’re building the train network Victoria needs and creating thousands of local jobs.”

The Government announced in August 2016 that it has shortlisted three JVs, which included some of the world’s most experience construction and tunnelling contractors.

The JV was also awarded the contract for early works in 2016, which are already well underway through Melbourne’s CBD.

More than 88 per cent of materials used to build the tunnels and underground stations will be sourced locally, including 93 per cent of the steel require for the project.

Major construction of the tunnel and associated stations are expected to start next year.
