XL Construction LLC

XL Construction LLC, a HUBZone-certified, SBA 8(a)-designated minority-owned and small disadvantaged business headquartered in Laurel, Maryland, delivers commercial and institutional building construction, mechanical systems upgrades, HVAC and electrical infrastructure services, and facilities maintenance and renovation work to federal agencies as a prime contractor across 85 awards totaling $1.79 billion in combined potential value.

The vendor competes predominantly under set-asides—8(a) sole source and competitive 8(a) designations dominate its award portfolio—with secondary activity under HUBZone and total-small-business set-aside vehicles. XL Construction operates exclusively as a prime contractor; it does not hold subcontractor positions in the source data. Across SCI-reportable service contracts, the vendor subcontracts an average of 26 percent of contractor hours to approximately 20 named subs, indicating a hybrid delivery model that builds core teams internally while leveraging specialized trade and mechanical subcontractors for discrete project scopes.

Customer concentration is bimodal. By award count, the top five funding offices account for 54 percent of recent awards, led by GSA Public Buildings Service National Capital Region (13 awards, $5.3 million combined potential value), Army Corps of Engineers Engineering District Baltimore (11 awards, $26.7 million), and GSA Region 3 (8 awards, $219.9 million). By potential value, the same agencies shift rank dramatically: Naval Facilities Engineering Command (NAVFAC) anchors 98 percent of combined potential value at $754.4 million across six awards, followed by the Air Force with $700.7 million across four awards, and GSA Region 3 at $219.9 million. This divergence signals that XL Construction holds two transformational IDV vehicles—a $750 million single-award NAVFAC indefinite delivery contract running through September 2030 and a $50 million Air Force multiple-award paving IDIQ through August 2028—that dwarf transactional task-order activity.

The NAVFAC $750 million IDC (awarded September 30, 2022, under competitive 8(a)) covers new construction, repair, renovation, and facilities maintenance across Naval and Marine Corps installations and federal facilities in the Washington D.C., Maryland, and Virginia region, with individual task orders ranging from $250,000 to $5 million. The Air Force $50 million paving MACC IDIQ (awarded August 17, 2023, under competitive 8(a)) authorizes paving and concrete repair work across Air Force installations over an eight-year period. Task orders executed to date on both vehicles exemplify the vendor's mechanical and infrastructure focus: electrical submetering ($148,000), fan coil replacement at Walter Reed National Military Medical Center ($248,888.88), MRI controls upgrades ($170,000), HVAC system replacements ($748,000 and $448,000 in separate orders), firing range exhaust system replacement ($888,000), and concrete repair ($182,000).

Beyond the two anchor IDVs, XL Construction holds additional parent vehicles: a $9 million single-award Army Corps of Engineers IDIC for civil works repairs, renovations, maintenance, and new construction at Washington Aqueduct sites (awarded December 4, 2023, under competitive 8(a)); a $200 million GSA Region 3 multiple-award contract for general construction services from Philadelphia to Richmond (awarded January 1, 2023, total-small-business set-aside) with expected task orders of $250,000 to $10 million; a $7.5 million GSA Region 3 repair-and-alteration contract throughout Maryland (awarded September 30, 2022, competitive 8(a)); and a $4 million NAVFAC mechanical IDIQ for new construction, repairs, and renovations in the Washington D.C. area (awarded September 24, 2021, 8(a) sole source). Most recently, XL Construction was awarded a single-award Smithsonian Institution Job Order Contract with a one-dollar ceiling for a five-year base extending through March 31, 2030, covering renovations, restoration, emergency response, and facility alterations to Smithsonian museums and facilities in the Washington D.C. metropolitan area (set-aside total-small-business).

Named award examples grounded in the vendor's core capability set include a $4.78 million 8(a) sole-source NIH definitive contract for critical air handling unit freeze-protection remediation and reheat pipe replacement (awarded September 21, 2023, completion July 31, 2024); a $2.62 million 8(a) sole-source NIH contract for refurbishment of air handling unit outside-air dampers on critical AHUs (awarded August 9, 2023, extended to April 30, 2025); a $2.19 million definitive contract from Army Corps of Engineers for INSCOM sidewalk restoration and electrical system modification at Fort Belvoir, Virginia (awarded October 9, 2024, no set-aside, completion April 11, 2026); a $1.73 million HUBZone delivery order from GSA Region 3 for replacement of three chillers at the W. Craig Broadwater Federal Building and Courthouse in Martinsburg, West Virginia (awarded April 5, 2024, completion June 30, 2025); and a $1.51 million 8(a) sole-source NIH contract for pump and tube-bundle replacement at Building 50 in Bethesda (awarded September 27, 2024, completion May 30, 2026).

Activity has remained steady at 11 awards in 2023 and 2024, declining to three in 2025 and one in 2026 year-to-date; the source carries awards from 2010 onward. Only one award (the $117 thousand Smithsonian delivery order) faces completion inside the next twenty-four months, yielding minimal recompete exposure in that window. The bulk of potential value—the two anchor IDVs with combined $800 million ceiling—extends through 2028 to 2030.

SCI-reported invoicing totals $12.7 million across FY2022–FY2024 (a strict subset excluding goods, micro-purchases, and classified work): $4.5 million in FY2022, $242 thousand in FY2023, and $7.9 million in FY2024. The SCI dataset reflects 3.1, 0.3, and 1.3 FTEs delivered respectively across those three years—a volatile trajectory reflecting task-order timing rather than steady staffing. Government-paid hourly rates on SCI-reportable prime contracts range from a 10th percentile of $0.00/hr (reflecting minimum-guarantee or fixed-deliverable orders) to a median of $329.24/hr and a 90th percentile of $1,072.32/hr, indicating a skilled labor portfolio spanning junior trades through senior engineering and project management.

XL Construction's federal portfolio is anchored to mechanical, HVAC, and electrical infrastructure for facilities maintained by NAVFAC and the Air Force within the Washington D.C. corridor and broader East Coast region. The vendor's set-aside posture (predominantly 8(a) and HUBZone) and capacity to hold large, multi-year IDVs position it as a capable competitor in the federal facilities construction market, with particular strength in Navy, Air Force, and General Services Administration customer relationships.
