Modernise dam near Brisbane Australia

VINCI wins a contract to modernise a dam near Brisbane in Australia

- Safety improvement and modernisation of the Cressbrook Dam in Toowoomba (Queensland)

Increasing flood capacity for greater climate resilience

- A project worth over €86 million

Seymour Whyte, a VINCI Construction subsidiary in Australia, has been awarded, in a consortium with the engineering company SMEC, the contract to improve Cressbrook Dam, in the Toowoomba region, around 100 km from Brisbane. The "alliance" type contract brings together the design-build consortium and the client, Toowoomba Regional Council, in a single team.

The project focuses on a dual objective: to increase the dam’s capacity in order to protect the Toowoomba region from flooding, and to strengthen the infrastructure's climate resilience.

Construction works, which will take around two years to complete, include upgrades to access roads, widening of concrete spillway, extensive upgrades to the dam’s filtration system, and raising the dam’s crest height.

Lastly, Seymour Whyte intends to deploy a major environmental scheme, including the recycling of materials for the construction of the dam wall and technical improvements to allow for natural fish migration.
