Ahrens Advances on T2D Project

Ahrens is delivering five sheds for the River Torrens to Darlington Project (T2D)

Ahrens continue to play a pivotal role in South Australia’s largest ever road infrastructure project, with the Waterloo Corner shed now complete and works progressing at the Southern and Northern Precinct Segment and Spoil Sheds.

Awarded five major industrial sheds across the River Torrens to Darlington (T2D) Project corridor, Ahrens is delivering critical infrastructure that must be in place before tunnel boring can begin.

The Waterloo Corner shed will be used to manufacture precast concrete tunnel segments that feed directly into the Tunnel Boring Machines (TBMs), which will operate 24 hours a day as they construct the twin tunnels.

With Waterloo Corner successfully delivered, focus has shifted to the Southern Precinct site. “Ahrens committed to a programme for this shed and so far we are tracking on schedule,” said Project Manager Josh Min.

The first shed proved invaluable in building momentum and understanding the client’s expectations.

“At the Waterloo site, Ahrens became familiar with T2D Project procedures and safety expectations. It was a great learning curve on the first shed and that’s been applied seamlessly to the next phase of works.”

Managing multiple live sites requires constant coordination.

“Communication with the client is key. We need to stay on top of workloads and ensure we have the right resources ready and waiting.”

In-house engineering continues to deliver as designs transition into construction.

“Having our own design capability has been a game changer. We can review drawings and discuss them before they’re issued for construction, which means we understand what’s required and can hit the ground running,” said Josh.

For Josh, the Project reflects Ahrens’ capability on the national stage.

“It proves that we are up for the challenge of being an integral part of the largest road infrastructure project in South Australia’s history.”

Thanks to the project delivery team led by Josh, Site Manager Ben Stevens and Senior Estimator Daniel Aloi.
