XL Construction LLC

XL Construction LLC, a HUBZone-certified, SBA 8(a)-designated minority-owned and small disadvantaged business headquartered in Laurel, Maryland, delivers federal construction, renovation, and facilities-maintenance services as a prime contractor across 89 awards with a combined potential value of $1.8 billion. The firm operates as a limited liability partnership and competes predominantly under set-aside vehicles — recent awards split across Total Small Business, Competitive 8(a), 8(a) Sole Source, and HUBZone set-aside designations, with a smaller volume of full-and-open awards.

XL Construction's capability portfolio centers on building systems and facility infrastructure work: HVAC replacement and upgrades (chillers, air handling units, fan coils), mechanical systems repairs, electrical submetering and fire protection system upgrades, plumbing and structural work, concrete repair, and campus-scale renovation projects. Representative work includes a $4.78 million definitive contract with the National Institutes of Health for critical air handling unit freeze-protection remediation and reheat pipe replacement (8(a) Sole Source, ultimate completion July 31, 2024); a $2.62 million delivery order with GSA for courthouse parking garage improvements in Greenbelt, Maryland (Total Small Business, October 1, 2026); a $2.62 million definitive contract with NIH for air damper refurbishment on critical AHUs (8(a) Sole Source, ultimate completion April 30, 2025); and a $2.19 million definitive contract with the Army Corps of Engineers for sidewalk restoration and electrical system modification at Fort Belvoir (October 9, 2024).

Customer concentration is heavily tilted toward military and federal facility owners. The top five funding agencies account for 52% of recent awards by count but 98% of combined potential value — driven by two dominant IDV vehicles. The Department of the Navy Naval Facilities Engineering Command leads on dollars with 6 awards carrying $754.4 million combined potential value, anchored by a single-award $750 million indefinite-delivery contract (awarded September 30, 2022, extending through September 29, 2030). The Department of the Air Force Headquarters District Washington follows with 4 awards carrying $700.7 million in potential value, anchored by a $50 million competitive 8(a) Paving MACC multiple-award IDIQ (awarded August 17, 2023, extending through August 16, 2028). GSA Public Buildings Service Region 3 holds 8 awards with $219.9 million in potential value from a $200 million multiple-award total small business IDV (awarded January 1, 2023, extending through December 31, 2026). By award count, GSA's National Capital Region leads with 13 smaller awards ($5.3 million combined potential value), and the Army Corps of Engineers follows with 11 awards ($26.7 million combined potential value). The dollar concentration reflects a small number of agency-wide vehicles rather than broad customer diversification.

XL Construction holds positions on six named parent vehicles. The Naval Facilities Engineering Command $750 million single-award IDV (IDIQ N4008022D1115) carries 7 task orders with $2.7 million combined potential value and funds mechanical, electrical, and infrastructure work across naval and Marine Corps installations in the Washington D.C., Maryland, and Virginia region. The GSA Region 3 General Construction Services contract, a $200 million multiple-award IDV, supports 3 task orders with $5.1 million combined potential value for general construction and renovation throughout the East Coast Corridor from Philadelphia to Richmond. The Air Force Bolling Air Force Base Paving MACC, a $50 million competitive 8(a) multiple-award IDIQ, carries 2 task orders with $183 thousand combined potential value. XL Construction also holds single-award IDCs: a $9 million competitive 8(a) Army Corps of Engineers contract for civil works repairs and maintenance at Washington Aqueduct sites (ultimate completion December 3, 2028); a $7.5 million competitive 8(a) GSA Region 3 contract for repair and alteration services throughout Maryland (ultimate completion October 23, 2027); and a $1 ceiling Smithsonian Institution single-award job order contract for museum and facility renovations in the Washington D.C. metropolitan area (awarded March 26, 2025, extending through March 31, 2030, set aside for Total Small Business).

Activity remains steady with 5 to 11 awards per year over the past five years, though volume has declined from 11 awards in both 2023 and 2024 to 3 in 2025 and 5 through mid-October 2026. The recompete cliff is modest: 5 awards with ultimate completion in the next twenty-four months carry a combined potential value of $5 million. By NAICS, work clusters in Commercial and Institutional Building Construction (54 awards), Plumbing, Heating, and Air-Conditioning Contractors (8 awards), and Highway, Street, and Bridge Construction (6 awards). By PSC code, the top categories are Repair or Alteration of Office Buildings (21 awards), Construction of Office Buildings (11 awards), and Construction of Miscellaneous Buildings (7 awards).

Service Contract Inventory data captures $18.3 million in SCI-reportable invoiced federal services revenue across fiscal years 2022 to 2025 (FY2022: $4.5 million, FY2023: $242 thousand, FY2024: $7.9 million, FY2025: $5.6 million). SCI-reported workforce ranged from 0.3 FTEs in FY2023 to 6.2 FTEs in FY2022 and FY2025, reflecting the project-based nature of construction delivery. Across SCI-reportable prime contracts, XL Construction sourced approximately 33% of contractor hours from subcontractors, engaging 24 named subs on mechanical systems work, structural repairs, electrical installation, and plumbing. Government-paid hourly rates on SCI-reportable work ranged from $0 per hour at the tenth percentile to a median of $377.47 per hour to $972.55 per hour at the ninety percentile, consistent with field-labor-intensive construction and equipment-intensive infrastructure work. XL Construction operates exclusively as a prime contractor with no sub-award footprint in the source data.
