Aurecon, in a joint venture with Jacobs (AJJV), has been appointed as lead designers for the WestConnex New M5 in Sydney, Australia. The CPB Contractors Dragados Samsung Joint Venture (CPBDS-JV) is the contractor for the project.

The New M5 is a key element of the WestConnex masterplan for Sydney. It is expected to double the capacity of the heavily congested M5 East motorway corridor by providing new 9 km long twin tunnels from Kingsgrove to a new interchange at St Peters. Aurecon will provide key engineering design services across design management, civil, tunnel, road, bridge, cut and cover, drainage, HV and LV, lighting, M&E spatial, water treatment, environmental, traffic modelling and buildings services.

“It is a project through which Aurecon can help shape a major city on the global stage, with the WestConnex motorway predicted to deliver A$20b in economic benefits to New South Wales,” said Geoff Linke, Aurecon’s managing director for Infrastructure. “Most importantly, the New M5 project will deliver significant benefits for Sydney motorists.”

WestConnex New M5 project consists of 9 km of twin road tunnels from the existing M5 East at Kingsgrove to a new interchange at St Peters. There are two primary tunnel cross sections for two lanes and three lanes. Ventilation facilities will be located at Kingsgrove, Arncliffe and St Peters. The St Peters Interchange will include numerous large box girder bridges.
