About the company
Samuel Holdings, LLC, doing business as Leumas Engineering Group, is a black American-owned, SBA 8(a)-certified small disadvantaged business based in St. Croix, U.S. Virgin Islands that provides facility infrastructure maintenance and emergency systems services to federal agencies as a prime contractor. Operating as a limited liability partnership, the vendor has built a narrow but active customer relationship exclusively with the National Institutes of Health Construction division at its Bethesda, Maryland campus.
The vendor's recent award portfolio consists entirely of three purchase orders and a single-award indefinite-delivery contract with NIH Construction, accounting for $458 thousand in combined potential value and one hundred percent of obligated dollars. The work centers on building systems maintenance and compliance services: a $274,986 firm fixed-price purchase order awarded September 25, 2026 for emergency shower preventive maintenance (three months of an overall option year, ultimate completion September 30, 2027); a $183,086 firm fixed-price purchase order awarded September 26, 2025 for backflow preventer re-certification and installation at Buildings 33 and 14B, plus new drain and piping systems, with weekend-hours scope for full replacement of failed preventers (ultimate completion September 25, 2026); and a single-award indefinite-delivery contract awarded July 29, 2026 for emergency shower survey, initial project management, annual certification, and documentation services (ceiling value zero dollars, period of performance through September 30, 2027). All awards carry no set-aside designation beyond the vendor's inherent 8(a) status. Award categorization reflects split focus between commercial building construction (two awards) and plumbing and HVAC contractor work (one award), with corresponding PSC coding for building repair and sewage/waste facility maintenance.
Activity has grown from one award in 2025 to two in 2026, but the portfolio remains heavily concentrated in one customer. One award carrying $275 thousand in potential value reaches ultimate completion within the next twenty-four months, creating immediate recompete exposure at NIH Construction. Samuel Holdings has no recorded federal sub-award activity and does not hold a seat on any government-wide or agency-wide vehicle.
