Senior Geotechnical Engineer

The Project:

The consortium of John Holland, Bouygues Construction, Arcadis Australia, Jacobs and Ventia has been selected to build South Australia's biggest-ever road infrastructure project. In partnership with the South Australian Government, this consortium forms the Torrens to Darlington (T2D) Alliance.

The Torrens to Darlington (T2D) Alliance, will deliver the final 10.5km section of the North-South Corridor, forming a continuous 78 km, non-stop, traffic light-free motorway, and contributing to a long-lasting legacy for the community and people of Adelaide.

The T2D Project involves constructing two separate tunnels – the Southern Tunnels and the Northern Tunnels connected by an open motorway, with a combined total distance of 10.5km, open to traffic in 2031.  The T2D project comprises the tunnels, surface works including road and bridge construction in addition to services buildings and complex mechanical and electrical infrastructure. The T2D Alliance is committed to providing opportunities for local people, Aboriginal workers, apprentices, trainees and job seekers who are long-term unemployed and offers people an incredible opportunity to be a part of an iconic project.
