About the company
Tetra Tech Inc., operating as Tetra Tech Divisions Division, is a large unrestricted engineering and consulting firm headquartered in Irvine, California, delivering architect-engineering, geotechnical services, environmental remediation, and construction management to federal agencies as a prime contractor. The vendor is a child entity of the parent Tetra Tech, Inc., and competes exclusively full-and-open without set-aside designations across its recent federal footprint.
Tetra Tech's federal work concentrates in water resource management, flood control, and environmental remediation services delivered to the U.S. Army Corps of Engineers and the Environmental Protection Agency. The top five customer agencies account for 93% of recent awards, with the Department of the Army Corps of Engineers and its regional engineering districts dominating both volume and dollar value. ENDIST Los Angeles and the parent Department of the Army Corps of Engineers together represent over 125 of the vendor's 136 recent awards, with combined potential value exceeding $126.2 million. EPA Region 9 rounds out the active set with five awards valued at $2.7 million for Superfund site support and technical consulting services. Representative work includes a $1.58 million delivery order from ENDIST Los Angeles for FY25 levee formal inspections (September 2025), a $750,000 delivery order for Rio de Flag Final Design-Supplemental environmental work (October 2025), a $2.34 million delivery order for Santa Ana River Mainstem Project construction monitoring and environmental services to the Corps (February 2022), and a $534,879 delivery order for Iron King Superfund site support from EPA Region 9 (May 2022).
Tetra Tech holds a significant indefinite delivery vehicle with the U.S. Army Corps of Engineers — a $46 million Indefinite Delivery Contract for geotechnical and architect-engineering services awarded in December 2024 with a five-year base period extending through December 2029. The parent IDCs under which Tetra Tech operates multiple task orders include Indefinite Delivery Contract W912PL15D0007 (28 task orders, $10.2 million combined potential value), W912PL09D0026 (22 task orders, $8.3 million), W912PL12D0012 (22 task orders, $5.8 million), W912PL17D0004 (19 task orders, $9.8 million), and W912P718D0001 (14 task orders, $9.4 million). Award activity has been modest in recent years — one award in 2026, four in 2025, and two each in 2023 and 2024 — following higher volumes earlier in the portfolio's history. Four awards with combined potential value of $5.6 million reach ultimate completion within the next twenty-four months and face recompete exposure.
Tetra Tech's capability framing is dominated by architect-engineering and geotechnical services (119 awards under NAICS Engineering Services, 97 awards under PSC Architect and Engineering–General: Landscaping, Interior Layout, and Designing), with environmental consulting services appearing in 15 awards. The vendor operates as a prime contractor on 100% of its recent awards, with no sub-award footprint captured in the source. Service Contract Inventory data for the vendor show minimal federal SCI-reportable service-contract activity, recording 0.4 FTEs across one subcontractor record in FY2024, indicating that the bulk of Tetra Tech's federal work is project-based architect-engineering and construction services rather than labor-hour service contracts above the SCI reporting threshold.
