Tetra Tech, Inc.

Tetra Tech, Inc., operating as Tetra TECH through its Tetra TECH Divisions, is a global provider of consulting, engineering, and technical services specializing in infrastructure development, environmental compliance, and program management. As a large for-profit corporate entity registered to receive federal awards since January 2012, Tetra Tech serves as a prime contractor across multiple federal agencies, delivering comprehensive architectural and engineering services for civil works projects, military construction initiatives, and specialized technical support. The company's federal contracting footprint reflects its established expertise in supporting critical infrastructure modernization and environmental sustainability efforts across the Department of Defense, U.S. Army Corps of Engineers, and related federal agencies.

Tetra Tech's recent federal contract awards demonstrate substantial engagement in architectural and engineering design services, environmental permitting and compliance activities, and infrastructure planning initiatives. The company has received delivery orders totaling over $42 million from the U.S. Army Corps of Engineers' Louisville District under the Infrastructure Investment and Jobs Act framework, including a $35.1 million award for 35% to 100% design services for the LaGrange Dam 1,200-foot lock expansion in Illinois, a $22.5 million environmental permitting and compliance support contract for the Sentinel Program at Francis E. Warren Air Force Base in Wyoming, an $8.5 million Kentucky Lock Approach Wall design task order, and a $2.9 million Lock and Dam 25 Navigation and Ecosystem Sustainability Program order. Additional recent awards include $1.17 million for Army Reserve Center of the Future concept development, $1.27 million for architectural and engineering services supporting an HVAC renovation at Wright-Patterson Air Force Base, and multiple smaller delivery orders for value engineering studies and feasibility-level design services. The company has also received a $5,000 minimum guarantee delivery order from the Engineering and Inventions Division of the Institute for Telecommunication Sciences at the National Institute of Standards and Technology. Across these awards, Tetra Tech frequently engages small business subcontractors, including women-owned and minority-owned enterprises such as Crawford Consulting Services, Inc., Athena Engineering & Environmental LLC, Ott-Sakai & Associates LLC, Elliott Bay Design Group LLC, and Stanley Consultants, Inc., to support specialized design, engineering, construction scheduling, and technical review functions. None of the company's recent prime contract awards carry small business set-aside designations, reflecting open competition procurement.

Tetra Tech maintains two active Indefinite Delivery/Indefinite Quantity contract vehicles that anchor its federal infrastructure services portfolio. The company holds a $200 million multiple-award IDIQ contract awarded May 17, 2023, by the U.S. Army Corps of Engineers' Louisville District under the Infrastructure Investment and Jobs Act, providing architectural and engineering design services for civil works projects within the Great Lakes and Ohio River Division through May 16, 2028. This vehicle enables individual task orders valued between $12 million and $30 million for horizontal civil works construction projects including dams, levees, bridges, buildings, and water resource structures, with performance locations dispersed across the designated geographic region. Additionally, Tetra Tech received a $49 million multiple-award IDIQ contract effective October 1, 2025, from the Engineering and Environmental District Portland, a defense component of the National Institute of Standards and Technology, providing comprehensive architectural and engineering services across the Portland Area of Responsibility with potential support extending to Seattle and Walla Walla regions through September 30, 2030. This contract includes a $5,000 minimum guarantee per firm and delivery of services according to negotiated Schedule of Rates and Statements of Work. Through the Louisville District vehicle, the company has demonstrated active utilization by issuing multiple delivery orders across infrastructure modernization, environmental compliance, and military construction projects, positioning Tetra Tech as a primary provider of specialized technical services supporting the federal government's significant capital infrastructure and environmental initiatives.
