Stormwater Infrastructure Upgrades – Nambour, Bli Bli & Caloundra

The Goal

Upgrade aging, non-compliant stormwater assets across three distinct urban locations. The works aimed to restore structural integrity, improve drainage capacity at vulnerable low points, and ensure safe, long-term maintenance access for the Council.

The Challenge

Executing deep excavations and heavy precast lifts within tight residential streets and live, complex traffic intersections. Our team had to carefully navigate existing underground services, such as water mains and optic fibre, while minimising noise and disruption to local residents and businesses.

The Solution

To safely deliver the upgrades, we implemented highly tailored traffic management schemes for each site. We systematically removed the old infrastructure and installed modern, high-capacity precast concrete lintels, chambers, and heavy-duty manhole covers. Following installation, we completed full structural pavement and asphalt reinstatement to match the existing road profiles seamlessly.

The Result

The local community now benefits from upgraded, fully compliant stormwater infrastructure that effectively manages water flow and reduces the risk of localised flooding. The roadways have been smoothly restored, ensuring a safer and more resilient environment for all road users.
