South Australia launches ROI for TD225 January 2023
The South Australian government is inviting Registration of Interest for the Torrens to Darlington (TD2) project.
The 10.5km T2D Project is the final and most complex section of Adelaide’s 78km North-South Corridor and the most significant infrastructure project ever undertaken in South Australia.
It comprises two sets of twin three-lane tunnels, lowered and ground-level motorways, as well as overpasses and underpasses and upgrades at key intersections. More than half of the project will be tunnels.
The scope includes:
- Contract No. 22C233 – T2D Main Works – the design, construction, testing, commissioning, and handover of the assets delivered by the project
- Contract No. 22C321 – T2D Maintenance and Incident Response – maintenance and incident response services post completion of any package of the Main Works for a defined term post opening completion
Main construction work is scheduled to commence in 2025 and the first TBM will be launched for the Southern Tunnel in 2026. The Southern Tunnel will be open to traffic in 2030 and the entire T2D Project will be open in 2031.
Earlier this month the South Australian government announced that in response to industry feedback, changes to the project design and a review of the procurement approach, an alliance contracting framework will be used.
