Seymour Whyte Alliance Secures Contract for Cressbrook Dam Safety Improvement Project

Seymour Whyte, in an alliance with SMEC and the Toowoomba Regional Council, has secured the Cressbrook Dam Safety Improvement Project, a vital project focused on enhancing flood capacity and resilience in the Toowoomba Region.

The project’s primary objective is to ensure the dam wall’s integrity during extreme flood events and safeguarding the downstream communities.

The upgrade will ensure the dam’s long-term viability and adherence to modern engineering standards.

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.

The Cressbrook Dam project’s key focus on sustainability includes:
• Maximising rock reuse.
• Enhancements to allow for natural fish migration.
• Extensive upgrades to the dam’s filtration system.
• Raising the dam crest height to increase flood capacity and resilience.

Scheduled to start in 2024 with key works expected to be complete in late 2025, and some ancillary works potentially required to the end of 2026, the project involves comprehensive construction activities, including road upgrades, spillway and dam wall reconstruction, and habitat restoration post-construction.
