Aecom, Cimic and CPB Contractors have been named as preferred contractors for a $1bn (£560M) package of works on the £6.2bn metro tunnel project in Melbourne, Australia.
The consortium is the front runner to build Metro Tunnel entrances, carry out works at the eastern and western tunnel boring machine portals including cut and cover tunnelling and turnbacks.
It will also include reconfiguration and realignment of existing railway lines to connect the new Metro Tunnel rail tracks to the existing surface network in Kensington and South Yarra.
The Rail Infrastructure Alliance (RIA) works package, is the last major contract as part of the Metro Tunnel project.
RIA will also deliver associated tunnel, track and signalling works along the Sunbury and Dandenong lines to support the reconfiguration of the rail network to support day one operations of the Metro Tunnel.
Around 1,000 people will work on the RIA package. Site preparations ahead of portal construction will start later this year, with most RIA works expected to be finished in line with the completion of the tunnels and stations, by the end of 2025.
CIMIC Group chief executive Michael Wright said: “Investment in major rail infrastructure in Victoria is providing CIMIC Group and CPB Contractors with a strong pipeline of opportunities, and it is our privilege to be delivering these significant works to support this city-shaping public transport initiative.
“CIMIC’s in-house engineering consultancy, EIC Activities, is also playing a key role in assessing all geotechnical and civil structure designs and challenges, to offer quality, cost-effective construction methodologies and solutions for the Alliance.”
The metro will comprise 9km of twin tunnels running from the west of the city to the south-east as part of a new Sunbury to Cranbourne/Pakenham line.
There will be five new underground stations at Arden – North Melbourne Station, Parkville – Parkville Station, Domain – Anzac Station, and two new CBD stations directly connected to the City Loop at Flinders Street (Town Hall Station) and Melbourne Central stations – State Library Station.
