About the company
Tetra TECH Inc.'s USI Division, operating as Tetra TECH Science, is a subsidiary of Tetra Tech, Inc. (Pasadena, California) that delivers architectural, engineering, and facility management services to the federal government as a prime contractor (97% of recent awards) on full-and-open bases without set-aside designations. The division is headquartered in Louisville, Kentucky, and competes in NAICS 541330 (Engineering Services) and PSC D (Architect and Engineering), with a recent prime footprint spanning 36 awards valued at $79.7 million combined potential value.
Customer concentration is extreme and tenure-based. The U.S. Army Corps of Engineers' Engineering District Louisville accounts for 22 awards and $70.5 million (88.6% of combined potential value) — the single largest customer across all five agencies the division serves. The Air Force Materiel Command holds 6 awards worth $6.1 million, the Air Force Research Laboratory (AFRL) at Wright-Patterson AFB holds 4 awards worth $1.7 million, and the broader Army Corps of Engineers holds 3 awards worth $1.4 million. The division's vehicle footprint reflects this concentration: it holds a $4.9 million single-award Indefinite Delivery Contract with Air Force Materiel Command through September 2028 for architect-engineer services at Wright-Patterson AFB, and sits on three larger IDCs issued by the Army Corps of Engineers — Contract W912QR19D0039 (16 task orders, $8.6 million combined potential value), Contract W912QR21D0072 (6 task orders, $9.2 million), and Contract FA860123D0005 (9 task orders, $2.9 million). Named work includes a $3.1 million delivery order for HPW Lab design-build-bridging services at Wright-Patterson, a $2.6 million award for architectural and engineering services supporting Yars Base Fire Station through ENDIST Louisville (ultimate completion January 2027), a $147 thousand Title II architectural and engineering delivery order for Naval Surface Warfare Center Crane in Indiana, and five consecutive delivery orders from AFRL and Air Force Materiel Command for facility renovation, HVAC repair, secure space build-out, and structural analysis work at Wright-Patterson AFB issued between May 2025 and February 2026, valued between $134 thousand and $486 thousand each.
Activity has grown to seven awards in 2025 from one award in 2022, though the most recent award (February 2026) represents a single delivery order. Within the next twenty-four months, five awards carrying combined potential value of $9.1 million will reach ultimate completion and face recompete exposure. As a subcontractor, the division delivers architectural and engineering design services to Black & Veatch Special Projects Corp. on the AMC-V (Acquisition Management Complex Phase V) A/E design project at Wright-Patterson AFB (award date January 2025).
