USACE Louisville Environmental and Restoration Services 2011-2017 (ERSC)

The U.S. Army Corps of Engineers Louisville District established this Master IDIQ for environmental and restoration services across all USACE mission boundaries on October 27, 2011, with the last date to order set for October 27, 2023—the vehicle is now closed to new orders as of 2 years and 8 months ago. The vehicle operates two tracks: Unrestricted and Small Business, with a shared ceiling of $450 million.

Task-order activity peaked in 2019 at 23 awards but declined sharply thereafter, with only 2 orders placed in 2021 (the final ordering year). The vehicle issued 201 task orders over its operational life, though momentum has stalled well before the October 2023 cutoff. Combined task-order potential value stands at $395.3 million, with $388.8 million obligated—98 percent of the ceiling—indicating the vehicle was substantially drawn down before closing.

Awarded work spans environmental remediation, site investigations, asbestos and hazardous-materials surveys, groundwater monitoring, well abandonment, radiological surveys, CERCLA support, and operations and maintenance at former military installations and ammunition plants. Mega-orders include a $30.3 million base integrated environmental support task (BIEST) to one prime, a $18.3 million remedial action at Somerville Depot, a $12.9 million Sharon Steel Farrell Works project, and a $3.2 million Tonawanda Landfill soils remediation for FUSRAP.

Concentration is moderate among primes by order count but highly skewed by value. Plexus Scientific Corporation leads in order count with 51 awards ($24.1 million combined potential value), followed by Pars Gannett Fleming Joint Venture with 43 orders ($13.4 million) and Earth Resources Technology with 28 orders ($12 million). However, four firms—Hydrogeologic ($97.7 million), Ch2M Hill Constructors ($90.2 million), URS Group ($45 million), and Aptim Federal Services ($35.2 million)—capture 76 percent of combined potential value, signaling that larger remedial projects went to established environmental contractors while smaller surveys and assessments distributed across a broader base.

Demand was concentrated at USACE Louisville District (147 orders, $106.4 million), which placed 73 percent of all orders. The broader USACE organization contributed 21 orders ($39.5 million), and secondary customers included USACE Savannah District ($40.3 million potential value across 6 orders) and Air Force IMSC Civil Engineer Center ($106 million across 6 orders).

Set-aside use was split: 56 percent of orders (112) carried no set-aside, while 44 percent (89) were designated small business, predominantly as sole-source awards under the Small Business Track rather than competitive small business orders.
