A contract for the investigations works, including further detailed geotechnical works, on the final 10.5-kilometre stretch of the North South Corridor has been awarded.
Golder Associates and WSP Australia have been awarded a $4.52 million contract to jointly undertake, from their Adelaide bases, the ground investigations work for the Torrens to Darlington Upgrade Project.
On-site investigations will be carried out across around 130 test sites beginning in August.
Minister for Transport, Infrastructure and Local Government Stephan Knoll said we are forging ahead with this mammoth project that will underpin thousands of jobs over the next decade and massively reduce travel times and congestion on one of our busiest roads.
“These are necessary investigatory works to help inform our decision about the future of the biggest job creating infrastructure project in South Australia’s history,” he says.
Geotechnical works are expected to provide more detail about the viability of tunnels on the project.
Knoll says there is already $5.4 billion on the table towards the completion of the most difficult part of the 78-kilometre motorway.
The number and the location of test sites for geotechnical investigation are designed to inform the geotechnical and hydrogeological conditions of a wide area and gain a comprehensive picture of the underlying soil and groundwater along the alignment.
