Contractors have been selected to build the twin tunnel entrances of the Melbourne Metro Tunnel Project. Minister for Public Transport Jacinta Allan announced a consortium comprising John Holland, CPB Contractors and AECOM have been selected as the preferred bidders to deliver the $1bn Rail Infrastructure Alliance (RIA) works package.
The package will include cut and cover and tunnelling works at the eastern and western tunnel entrances to connect the new rail tunnel to the existing network, along with additional selected station upgrades, tunnel, track and signalling works along the Sunbury and Dandenong lines.
This is the third package of Metro Tunnel works to be delivered by John Holland, following the delivery of the early works and the major works package to build the project’s 9km twin tunnels and stations.

Around 1000 people will work on the RIA package, which is part of the $11 billion project that is on budget and ahead of schedule. Site preparations ahead of portal construction will commence 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.
