VINCI Construction’s Australian subsidiary, Seymour Whyte in an alliance with SMEC have secured a €86m contract to upgrade Cressbrook Dam in Toowoomba, Queensland.

Seymour Whyte, a VINCI Construction subsidiary in Australia and engineering company SMEC has been awarded 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 the 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.

John Kirkwood, Seymour Whyte’s Chief Executive Officer and Managing Director, said the project marks a critical step forward in infrastructure development and environmental stewardship.

“Our Project Alliance with SMEC and Toowoomba Regional Council underlines our dedication to delivering innovative solutions that meet the dual challenges of modern engineering and ecological sustainability, with every aspect carefully planned to minimise impact and maximise benefit,” he said.

“This dam project diversifies Seymour Whyte’s water infrastructure portfolio and cements our environmental ambition, particularly in maximising circular economy principles for the dam safety improvement works.”

“Our approach to this project is ingrained in environmental and sustainability consciousness. Every step will be taken in our design and construction to develop innovative solutions for the dam’s long-term viability and adherence to modern engineering standards.”

“Seymour Whyte is looking forward to working with Alliance Partners Toowoomba Regional Council and SMEC to deliver this project for Council and the region”, Mr Kirkwood added.

SMEC’s Design Manager for the project, Louiza Van Vuuren stated, “It is an honour to be part of the team to deliver the Cressbrook Dam Safety Improvement Project.”

“We are looking forward to working with Toowoomba Regional Council and Seymour Whyte to deliver technical excellence on Council’s biggest project to date.”

“Our team is committed and excited to successfully deliver the project, which will extend the safe operation of this critical water infrastructure asset.”

The improvements are required to meet acceptable flood capacity modelling guidelines revised by the Australian National Committee on Large Dams (ANCOLD).
