About Tetra TECH Inc.
Tetra Tech Inc., a global engineering and consulting firm headquartered in Irvine, California, is a registered federal contractor specializing in comprehensive technical services across environmental remediation, infrastructure development, water resource management, and geotechnical engineering. As a for-profit corporate entity, Tetra Tech leverages its extensive capabilities to support federal agencies in executing complex projects related to flood control, environmental compliance, hazardous waste remediation, and infrastructure rehabilitation. The company maintains a strong track record with multiple federal agencies and has established itself as a reliable prime contractor for delivery orders and task orders under various indefinite delivery contracts.
Tetra Tech has demonstrated its expertise through a diverse portfolio of federal contract awards spanning multiple agencies and project types. The company has executed delivery orders and task orders for the U.S. Army Corps of Engineers, Environmental Protection Agency Region 9, and the Department of Defense's ENDIST Los Angeles division, with contract values ranging from approximately $41,600 to $2.3 million. Notable projects include the Rio de Flag Final Design-Supplemental project ($750,000), FY25 Levee Formal Inspections ($1.58 million), Upper Rio Grande Water Operations Model work ($199,973), Santa Ana River Mainstem Project construction monitoring and environmental services ($2.34 million), Hamilton Wetland Restoration Project site monitoring ($1.44 million), Lower Norco Bluffs geotechnical services ($1.47 million), and Riverside Levee rehabilitation ($1.34 million).

Environmental remediation work includes technical support for the Iron King Mine Superfund Site and Rams Mine Site architect-engineering services through EPA Region 9. The company frequently partners with subcontractors such as Newfields Companies LLC and Environmental Science Associates to provide specialized services. None of Tetra Tech's recent federal contract awards utilized socioeconomic set-asides, reflecting its status as a large, unrestricted prime contractor.
Tetra Tech holds a $46 million Indefinite Delivery Contract for Geotechnical and Architectural Engineering (AE) Services awarded by the U.S. Army Corps of Engineers on December 27, 2024, with an ultimate completion date of December 26, 2029. This five-year base period contract provides a broad technical services vehicle enabling the issuance of individual task orders for engineering design, construction management, environmental assessments, feasibility studies, and scientific analyses supporting the Corps' infrastructure development, flood control, hazardous waste remediation, natural resource management, and facilities construction initiatives. The IDC includes a $1,000 minimum guarantee task order and has already generated multiple delivery orders, including the Upper Rio Grande Water Operations Model ($199,973), FY25 Levee Formal Inspections ($1.58 million), and FY25 Geotech MATOC Minimum Guarantee.
