Following the successful completion of the temporary works, Tas Marine was awarded the contract to deliver the full Bellerive Stormwater Upgrade — the City of Clarence’s largest infrastructure project to date.
The upgrade involved constructing a sheet pile cofferdam across Bellerive Beach to enable trench excavation for the new sewer outfall. Tas Marine mobilised its jack-up barge with a 22t excavator for seaward dredging, alongside a 26t excavator with a sheet pile vibrator on the land side. More than 200t of sheet piles and steel struts were installed to form the temporary structure, which was removed once the outfall pile was completed.
Now fully operational, the new stormwater system at Beach Street significantly reduces flood risk to surrounding roads and properties during heavy rainfall.
Tas Marine is proud to have delivered this critical project with a strong focus on protecting the local environment and community. Working closely with the City of Clarence and stakeholders, the team implemented strict environmental protocols to minimise disruption to the marine environment, safeguard coastal ecosystems, support long-term sustainability goals for the region, and build greater resilience for the community.
