The consortium RIA (Rail Infrastructure Alliance) comprising John Holland (a subsidiary of Chinese firm CCCG), CPB Contractors (part of CIMIC Group, whose parent company is German construction firm Hochtief) and AECOM (the American multinational engineering and design firm) has been selected as the preferred bidders to build the Metro Tunnel entrances in Kensington and South Yarra at Melbourne: 9 km of twin tunnels beneath the CBD, in an effort to ease congestion on the City Circle and surrounding lines.

CPB Contractors and John Holland are equal construction partners in the contract, and AECOM is the design partner. The $1 billion works 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.

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.
