American multinational engineering firm AECOM has won a contract worth approximately A$70m ($50m) to provide a complete range of design services for the delivery of the A$11bn ($7.8bn) Melbourne Metro Tunnel Project.
AECOM is part of the Rail Infrastructure Alliance (RIA), which has signed a contract worth approximately A$1bn ($715m) with the Victorian Government for the metro project.
The Rail Infrastructure Alliance consists of CPB Contractors and John Holland, with AECOM as the design partner, in addition to project owner Rail Projects Victoria and rail franchisee Metro Trains Melbourne.
AECOM’s affiliates will design all elements of the project, such as tunnel entrances, brown-field rail network enhancements and station improvements.
The company’s affiliates will also be responsible for obtaining various planning and environmental approvals relating to the upgrade of the rail network and helping to reduce the project’s impacts.
AECOM CEO of Australia and New Zealand Todd Battley said: “This is a highly complex and challenging design brief, which will connect the new 9 km Metro tunnels to the existing live rail corridors bringing the trains above ground and allowing them to seamlessly continue their journey along the network.”
The Rail Infrastructure Alliance has begun preparatory works, including geotechnical, service and site investigations, at Kensington, South Yarra and West Footscray, which will facilitate planning and design of the western and eastern tunnel portals that will connect with new stations at Arden Street, Parkville, CBD North, CBD South and Domain.
The company said that it has already started mobilising combined local and global teams to bring the best of AECOM’s tunnel portal design, geotechnical and urban heavy rail capability to this project.
Upon completion, the project will keep a growing Melbourne moving and leave a lasting legacy of rail design expertise, which Victoria can export to the world, it said.
More than 1,000 people are expected to work on the Rail Infrastructure Alliance package of works, including nearly 100 apprentices, trainees and engineering cadets.
