About Tetra Tech, Inc.
Tetra Tech, Inc. 117-ECS Division delivers environmental site assessment, mine remediation, geotechnical investigation, construction inspection, and environmental compliance monitoring services to federal land and resource agencies as a prime contractor, operating exclusively on full-and-open contracts with no set-aside utilization. The division is a child entity of Tetra Tech, Inc., a for-profit corporation headquartered in Pasadena, California, with divisional operations based in Billings, Montana.
The division's customer concentration is extreme: the Department of Agriculture Forest Service Region 1 (Northern Region) accounts for 13 of 36 awards (58% of award count) valued at $16 million combined potential value — nearly 91% of the division's total federal contract footprint. Recent representative work includes a $160.8 thousand firm fixed-price delivery order from the Forest Service for the Beal Mountain Mine CERCLA remediation project at Beaverhead-Deerlodge National Forest (completion December 31, 2027); a $228.3 thousand delivery order for Riley Pass 2026 construction inspection in Ludlow, South Dakota (completion December 31, 2026); subsurface geotechnical investigation drilling at Riley Pass Bluff valued at $141.5 thousand (completion October 30, 2026); and Phase I environmental site assessment of the Crystal Mine land exchange at Beaverhead-Deerlodge National Forest valued at $32.2 thousand (completion January 31, 2027). Additional customers include the Department of the Interior Departmental Offices, the Department of the Interior Bureau of Indian Affairs Rocky Mountain Region, the Department of Veterans Affairs, the Department of Health and Human Services Indian Health Service, the Environmental Protection Agency Region 1, and the General Services Administration.
Tetra Tech ECS holds a $15 million single-award Indefinite Delivery Contract with EPA Region 1 for CERCLA Mine Reclamation support (completion November 30, 2030), under which three delivery orders have been issued to date. The division also places work under a second IDV (contract 1401000188C39, source details not provided). Activity has accelerated sharply — one award in 2025 to thirteen in 2026 — with eleven awards (combined potential value $977 thousand) reaching ultimate completion inside the next twenty-four months and therefore facing recompete. Work spans environmental engineering, geotechnical investigation, environmental compliance monitoring, and construction administration, concentrated in Montana and South Dakota, with performance locations including Billings, Bozeman, Ludlow, and Walkerville, Montana, and Browning, Montana.
