The Victorian Government has announced a consortium comprising John Holland, CPB Contractors and AECOM as the preferred bidders to deliver the $1 billion Rail Infrastructure Alliance (RIA) works package on Melbourne’s Metro Tunnel.
The $1 billion RIA works package, is the last major contract as part of the $11 billion Metro Tunnel project.
The consortium will build the tunnel entrances in South Yarra and Kensington, which will each see thousands of passengers pass through every hour before their trains go underground and onto twin 9km tracks beneath Melbourne.
New high-capacity signalling will allow trains to pass through the new entrances every two to three minutes in each direction – a vital part of the Metro Tunnel, which will deliver major benefits for suburban passengers.
The RIA also includes works on train lines out in the suburbs to maximise the benefits of the Metro Tunnel and take full advantage of the extra capacity it creates.
Around 1000 people will work on the RIA package.
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.
