Lillard & Clark Construction Co Inc.

Lillard & Clark Construction Co Inc., a Denver-based for-profit Subchapter S corporation, performs heavy civil engineering construction and dam maintenance work for the federal government exclusively as a prime contractor, competing predominantly under small business set-asides across the Department of the Interior's Bureau of Reclamation and the Department of the Army.

The vendor's footprint is highly concentrated in a single customer: the Bureau of Reclamation accounts for 25 awards worth $49.5 million in combined potential value, representing 91% of all recent awards by count and 100% of documented potential value. The Department of the Army holds 24 awards with no stated potential value; the Army Corps of Engineers holds one additional award. Lillard & Clark competes 100% as a prime contractor with no sub-award activity, operating under multiple Army Corps of Engineers IDIQs (DACW4580C0215, DACW4584C0194, DACA4587C0162, DACW4581C0083, DACW4583C0411) that collectively account for seven task orders. The vendor's capability portfolio centers on dam infrastructure sustainment and heavy civil construction: representative work includes the $14.66 million Green Mountain Powerplant penstock rehabilitation in Colorado (awarded January 2022, firm fixed-price, no set-aside), the $1.78 million Norton Dam wire rope replacement in Kansas (awarded June 2024, total small business set-aside), the $388,846 Shadehill Dam ladder, platform, and guardrail replacement in South Dakota (awarded June 2025, total small business set-aside), the $321,000 Rio Chama Trail staircase and suspension bridge removal in New Mexico (awarded May 2026, total small business set-aside), and the $345,000 Downs Protective Dike vertical turbine pumping unit removal and reinstallation in Kansas (awarded September 2026, no set-aside). Top NAICS categories include Other Heavy and Civil Engineering Construction (10 awards), Painting and Wall Covering Contractors (4 awards), and Water and Sewer Line and Related Structures Construction (2 awards); PSC codes cluster around dam repair and alteration (7 awards) and dam maintenance (2 awards).

Activity has declined sharply: the vendor recorded two awards per year in 2021, then dropped to one award each in 2022, 2024, and 2025, with two awards in 2026. Only two awards carry ultimate completion dates within the next twenty-four months, totaling $666 thousand in combined potential value and representing minimal recompete exposure. Across SCI-reportable prime contracts, Lillard & Clark invoiced $11.1 million from FY2022 through FY2025, with peak activity in FY2023 at $5.2 million across 6.6 FTEs and a sharp decline to $1.7 million in FY2025 across 1.5 FTEs. Government-paid hourly rates on SCI-covered work ranged from a median of $577.60 per hour to a 90th percentile of $700.04 per hour. The vendor engages subcontractors for approximately 19% of contractor hours on average across prime contracts, with three named subcontractors appearing in recent SCI records, indicating a primarily self-performing operational model supplemented by selective subcontracting for specialized work.
