Tetra Tech, Inc., headquartered in Pasadena and recognized as a leading consulting and engineering services provider, has recently secured a $33 million task order from the U.S. Army Corps of Engineers Rock Island District Great Lakes and Ohio River Division. 

The contract calls for the provision of architectural and engineering services aimed at designing a new 1,200-foot navigation lock on the Illinois River.

Awarded through the Corps of Engineers Great Lakes and Ohio River Division’s Infrastructure Investment and Jobs Act Contract, the task order emphasizes Tetra Tech’s expertise in contributing to critical infrastructure projects. 

“The USACE Rock Island District maintains navigable waterways that are essential to the transportation of goods throughout the Midwest,” Dan Batrack, Tetra Tech Chairman and CEO, said in a statement. “Tetra Tech looks forward to using our Leading with Science approach to design systems that improve critical infrastructure, support public safety, and enhance the resilience and reliability of U.S. waterborne transportation supply chains.”

Tetra Tech’s team of scientists, consultants, and engineers will lead the design efforts for the new lock chamber, focused on enhancing efficiency, reliability, and safety for navigation traffic along the Illinois River.

The planned 1,200-foot navigation lock will be a significant upgrade over the existing system, aiming to reduce wait times by over 70%, accommodate larger vessels, and enhance mariner safety. 

The strategic project aligns with the priorities of the Corps of Engineers’ Navigation and Ecosystem Sustainability Program.

Tetra Tech has over 27,000 employees worldwide helping to provide solutions to complex problems in water, environment, sustainable infrastructure, renewable energy, and international development.
