About the company
Alliant Corporation, a service-disabled veteran-owned small business headquartered in Knoxville, Tennessee, operates as a prime contractor (100% of recent awards) delivering environmental remediation, engineering consulting, and hazardous-materials assessment services to federal agencies under full-and-open and Total Small Business set-aside procurements. The company competes exclusively as a prime; it holds no subcontractor relationships in the source data.
Alliant's customer base concentrates heavily on two Army Corps of Engineers entities. The Department of the Army Corps of Engineers Engineering District Louisville accounts for 31 awards totaling $76.7 million in combined potential value, followed by the broader Department of the Army Corps of Engineers with 8 awards worth $51.9 million. Together these two customers represent 74% of recent awards by count. The rankings shift significantly by dollar value, however: the Department of Energy National Nuclear Security Administration anchors a single award valued at $91 million — the company's largest single contract — which carries 38% of the vendor's total combined potential value across all 74 awards. This divergence signals a portfolio at risk of concentration: while Alliant maintains steady volume with the Corps, the NNSA award dominates the financial picture. The Department of Interior Bureau of Reclamation, Department of Energy Office of Environmental Management, and Department of the Army Installation Management Command Southeast Region round out the top-five customer set by value.
Alliant holds seats on multiple vehicle platforms. The Multiple Award Schedule carries 19 task orders valued at $94.4 million and represents the vendor's largest vehicle by dollar volume. Two core Indefinite Delivery Contracts with the Army Corps of Engineers — one for cost engineering services (10-million-dollar ceiling, 6 task orders, $22.5 million potential value) and one for demolition and environmental remediation across the Great Lakes and Ohio River Division (40-million-dollar ceiling, carrying 26 task orders totaling $7.4 million in obligated value) — anchor recurring delivery-order activity. Alliant also sits on the Professional Services Schedule with 9 task orders worth $2.8 million.
Representative capability work spans environmental assessment, PFAS remediation investigation, and facilities decommissioning. A $17.7 million delivery order from ENDIST Louisville (awarded June 2023) covers PFAS and 1,4-dioxane remedial investigation at Chanute former Air Force Base under a Total Small Business set-aside, extending through June 2028. A $1.999 million Phase I PFAS remedial investigation at Grissom Air Reserve Base (ENDIST Louisville, September 2021) demonstrates sustained DoD environmental-remediation work. A $576 thousand environmental assessment for Area A at Wright-Patterson Air Force Base (DLA ENDIST Louisville, September 2022) and a $1.9 million long-term monitoring and operations contract with the Corps of Engineers Louisville District (May 2022) illustrate the vendor's environmental compliance and site stewardship footprint. Recent awards include a $448 thousand indoor air quality testing contract with the Department of Veterans Affairs (June 2026, extending through May 2031) and a $69 thousand Job Hazard Analysis web-based subscription service delivery order with the Bureau of Reclamation (July 2023), both firm fixed-price with no set-aside applied.
Activity shows episodic awards: two in 2019, four in 2021, four in 2022, five in 2023, and one in 2026 to date. Four awards totaling $19.8 million in combined potential value reach ultimate completion inside the next twenty-four months and therefore represent near-term recompete exposure. The company's primary NAICS concentration sits in Engineering Services (36 awards) and Environmental Consulting Services (23 awards), with secondary exposure in medical-instrument manufacturing (4 awards) and custom programming (2 awards). PSC coding aligns with architect-and-engineering and environmental-assessment services.
Alliant maintains seven named subsidiaries, all structured as service-disabled veteran-owned joint ventures or small disadvantaged business partnerships: Alliant-Srs JV LLC, Alliant-Ati JV LLC, TTL-CTI LLC, Alliant-Seres JV LLC, Alliant-Aerostar JV LLC, Alliant Perma-Fix Environmental Solutions LLC, and Alliant-Cape JV LLC. These subsidiaries preserve the parent's SDVOSB posture across teaming arrangements and allow the company to partition environmental-remediation and engineering-services work into separate operational units while maintaining uniformity in veteran ownership and small-business certification.
