About the company
Lewis Environmental Consulting, LLC, a Kentucky-based small business limited liability company, provides freshwater mussel and dive survey services to the U.S. Army Corps of Engineers as a prime contractor under Total Small Business set-asides, with 100% of its federal work concentrated in prime contract awards and 97% of its award volume from Army Corps of Engineers districts.
The company's capability portfolio centers on biological and ecological survey work: freshwater mussel population assessments, underwater dive investigations, mussel relocation services, and biological reporting to support the Corps' navigation infrastructure maintenance, dredging operations, and environmental stewardship missions across the Ohio River basin and its tributaries. Representative work includes a $115,490 delivery order from ENDIST Huntington (awarded July 1, 2026) for mussel survey and characterization at Ohio River maintenance dredging locations, a $176,665.50 purchase order from the Army Corps for mussel survey and relocation work at Chickamauga Lock in Tennessee (August 2024), and a $153,957 firm fixed-price delivery order from ENDIST Pittsburgh for pre-dredging biological mussel survey at Allegheny River Pool Six (July 2025). Performance locations span Kentucky, Tennessee, West Virginia, Indiana, and Pennsylvania.
The vendor holds a single-award $1.25 million Indefinite Delivery Contract (W912QR24D0015) with ENDIST Louisville, awarded February 9, 2024, running through February 8, 2029, under Total Small Business set-aside designation and NAICS 541370 (Environmental Research and Consulting Services). This parent IDC anchors the majority of recent task order activity; as of July 2026, Lewis has received 11 delivery orders against this vehicle valued at $717 thousand combined. The source documents four additional legacy IDCs: W912QR09D0011 (33 task orders, $992 thousand), W912QR19D0025 (21 task orders, $1.2 million), and W912QR14D0019 (17 task orders, $1.2 million), reflecting a long-standing contractual relationship with the Corps dating to at least 2009.
Customer concentration is absolute: the top five Army Corps of Engineers district offices (Louisville, unspecified Louisville District line, Huntington, Nashville, and Pittsburgh) account for 97% of award count and 98% of combined potential value. ENDIST Louisville alone represents 36 awards valued at $7.1 million. Lewis has no teaming or subcontract footprint — all 92 tracked awards are prime contracts, and the vendor operates exclusively with the Army Corps of Engineers across its operational geography.
Award activity peaked in 2024 at 10 contracts, declined to 5 in 2025, and shows 2 awards in 2026 year-to-date. Combined potential value across all 92 awards totals $10.8 million, with $4.6 million obligated (42% of potential value). Four awards carry completion dates within the next twenty-four months with combined potential value of $324 thousand — a modest recompete exposure relative to the overall portfolio. The vendor's work codes consistently under surveying and mapping services (86 awards), marine engineering (41 PSC awards), and animal/fisheries special studies (18 PSC awards), with secondary work in environmental assessment and consulting.
