Hamilton Pacific Chamberlain LLC

Hamilton Pacific Chamberlain LLC, a Service-Disabled Veteran-Owned Small Business headquartered in Waldorf, Maryland, operates as a prime contractor delivering construction, renovation, and facilities maintenance services to federal agencies, with all 496 recent awards in its prime portfolio and zero subcontract activity in the sample.

The vendor's capability footprint centers on commercial and institutional building construction (356 awards), with particular depth in VA medical center and federal facilities work—HVAC system replacements, plumbing and mechanical upgrades, roof repairs, interior renovations, and specialized infrastructure projects like Legionella control systems and fire protection installations. Representative work includes a $16.3 million exterior granite repair project at Washington DC VA Medical Center (awarded September 30, 2024, SDVOSB set-aside); a $7.87 million hot water circulation improvement and Legionella control system at Baltimore VA Medical Center (awarded April 4, 2022, SDVOSB set-aside); a $4.9 million HVAC renewal and system upgrade at Independence Hall in Philadelphia under the Great American Outdoors Act MATOC (awarded September 26, 2022, total small business set-aside); a $3.29 million administration and maintenance building renovation at Black Hills National Cemetery (awarded December 1, 2023, SDVOSB set-aside); and a $999.99 million FAA Basic Ordering Agreement for Design/Build and Bid/Build construction services at Air Traffic Control facilities across Eastern, Central, Western, and Alaska regions (awarded July 6, 2023, no set-aside). Across SCI-reportable service contracts, Hamilton Pacific Chamberlain invoiced $148.7 million over fiscal years 2022–2024, with government-paid rates spanning from a 10th percentile of $51.34/hr to a median of $242.86/hr and a 90th percentile of $1,306.02/hr, reflecting a labor mix spanning trade workers through specialized technical and project management roles.

Customer concentration is sharp and VA-centric. The Department of Veterans Affairs Veterans Integrated Service Network 5 (VISN5) dominates both by volume (109 awards) and dollars ($932.1 million combined potential value), anchored by a $300 million five-year multiple-award IDIQ for construction services in Maryland, Washington D.C., and West Virginia (awarded February 22, 2023, SDVOSB set-aside, through February 2028). The National Cemetery Administration trails in volume (137 awards, $212 million potential value) but aggregates multiple $49 million, 10-year regional IDIQs across the North Atlantic, Continental, and Pacific Districts. Together, VISN5, National Cemetery Administration, and Veterans Integrated Service Network 4 (25 awards, $262.3 million) account for substantial dollars. Beyond VA, Hamilton Pacific Chamberlain holds the $999.99 million FAA Basic Ordering Agreement, a $99 million U.S. Army Corps of Engineers Charleston District MATOC for design-build and design-bid-build general construction (awarded September 18, 2025, SDVOSB set-aside, through March 2031), a $48 million USDA Office of Operations indefinite delivery contract for construction and design-build work at Washington D.C. and Beltsville facilities (awarded August 31, 2022, SDVOSB set-aside, through August 2027), a $75 million Government Accountability Office construction services IDIQ (awarded September 30, 2022, no set-aside, through September 2027), and a $250 million Great American Outdoors Act MATOC shared with the Department of the Interior and U.S. Forest Service for maintenance and repair on federal lands.

The vendor operates predominantly under SDVOSB set-asides. Across the 496 awards in the recent portfolio, service-disabled veteran-owned small business designations dominate definitive contracts and delivery orders, while total small business set-asides appear on work under the Great American Outdoors Act MATOC and related Interior/Forest Service vehicles. Full-and-open procurements occur but are a minority posture—the FAA BOA and some GAO contracts carry no set-aside language. Activity has been steady: 48–50 awards annually from 2022 through 2024, declining slightly to 37 in 2025 and 22 in 2026 (partial year). Combined potential value across all awards stands at $3.43 billion, though only $278.3 million (8%) has been obligated, reflecting the preponderance of indefinite delivery vehicles with unexercised option periods and future task order capacity.

On SCI-reportable service contracts captured above the $150,000 threshold, Hamilton Pacific Chamberlain shifted from minimal federal service activity in FY2022 (0.4 FTEs, $673 thousand) to substantial scale by FY2023–2024, ramping to 212 FTEs and $70.9 million invoiced in FY2023 and 247 FTEs and $77.1 million in FY2024. Across SCI prime contracts, the vendor subcontracted roughly 15 percent of contractor hours to 183 named subcontractors, indicating a primarily self-performing model with selective subcontracting for specialized trades or surge capacity. Recompete exposure in the next twenty-four months touches 25 awards valued at $61.5 million combined potential value, a manageable cliff given the size of the active portfolio, though several regional cemetery IDIQs and the FAA BOA represent renewal opportunities of strategic importance.

Hamilton Pacific Chamberlain competes across 64 distinct federal customer agencies. Outside the VA ecosystem, the vendor's Midwest and southern presence is anchored by the Great American Outdoors Act MATOC (44 task orders, $20.4 million value), which has driven multiple park, forest, and wildlife refuge facility awards. The company's ownership structure as a service-disabled veteran-owned enterprise, paired with its depth in construction delivery across civilian federal agencies, positions it as a preferred prime under SDVOSB set-aside solicitations—a competitive posture unlikely to shift absent changes to SBA classification.
