USACE Southwest Division Environmental Remediation Services 2020-2025

The U.S. Army Corps of Engineers Engineering District Tulsa established a $45 million shared-ceiling Master IDIQ for environmental remediation services within the Southwest Division geographic boundaries on April 16, 2020, with ordering authority closing on April 15, 2025. The vehicle is now closed to new task orders and has reached 95% obligation ($43.6 million obligated of $46 million combined task-order potential value).

The vehicle procures firm-fixed-price remediation and investigation services for contamination from pollutants, toxic substances, radioactive and hazardous materials, and Munitions and Explosives of Concern (MEC). Awarded task orders span preliminary assessments, site inspections, remedial investigations, feasibility studies, remedial design, performance-based remediation, long-term monitoring and operations, well abandonment, remedial actions, closure activities, and associated planning and engineering support. Work has concentrated on former military installations and FUDS projects across the Southwest Division, including sites in Texas, Louisiana, Arkansas, and Oklahoma.

Four small-business primes shared 11 task orders, with competition highly concentrated. Ayuda-Plexus Joint Venture LLC and EA Engineering, Science, and Technology, Inc., PBC dominate, holding $25.3 million and $20.7 million in combined potential value respectively—roughly 99% of the vehicle's total. Kemron Environmental Services, Inc. and Bay West - Trevet Joint Venture LLC each received one small-value order. Ordering activity declined sharply after 2021, with only one task order awarded in 2024 (September 2024); three orders in 2021, three in 2022, four in 2020, and none in 2023 signal a wind-down pattern consistent with vehicle closure.

Set-aside distribution tilted unrestricted. Eight of 11 orders (73%) used no set-aside, while three (27%) were competed as Total Small Business. Customers concentrated on Army CONUS installations: Fort Worth District (2 orders, $15.1 million), National Capitol Region Humphreys Engineer Center (2 orders, $14.2 million), and Headquarters Military Programs (2 orders, $12.5 million) accounted for most ordering activity. Task-order ceiling values ranged from guaranteed minimums of $2,500 to performance-based remediation orders exceeding $13 million.
