Hamilton Pacific Chamberlain LLC

Hamilton Pacific Chamberlain LLC, a Service-Disabled Veteran-Owned Small Business (SDVOSB) based in Waldorf, Maryland, operates as a prime contractor delivering construction, renovation, and facilities maintenance services to federal agencies, primarily the Department of Veterans Affairs and the Department of the Interior. The company competes predominantly under SDVOSB set-asides and total small business designations, reflecting its veteran-owned status as a core competitive advantage across the federal marketplace.

Hamilton Pacific Chamberlain's capability portfolio centers on concrete construction and building systems work: HVAC system replacement and upgrades, plumbing and mechanical installations, roof repairs and replacements, fire protection system installation, water infrastructure projects, and specialized medical facility renovations. Representative examples include a $16.3 million exterior granite repair and renovation contract at the Washington DC VA Medical Center (Veterans Integrated Service Network 5, September 2024), a $6.1 million fire protection corrections contract at Durham VA Health Care Center (Veterans Integrated Service Network 6, August 2024), a $4.9 million HVAC renewal and system upgrade at Independence Hall in Philadelphia (Department of the Interior Northeast Region, September 2022), and a $2.9 million fire protection system installation at Tumacacori National Monument in Arizona (National Park Service Intermountain Region, July 2026). The company also executes smaller maintenance and repair orders—sidewalk replacements, irrigation system repairs, parking lot resurfacing, electrical work, and interior renovation—at VA medical centers, national cemeteries, and federal facilities nationwide.

Customer concentration runs heavily to the Veterans Affairs ecosystem. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 5 (VISN 5)—which oversees VA medical centers in Maryland, Washington D.C., and West Virginia—anchors 111 awards valued at $932.4 million combined potential value, representing 27% of total awards and 43% of combined potential value across the entire portfolio. The National Cemetery Administration adds 140 awards worth $212.4 million (26% of all awards by count, 6% of potential value), indicating high-volume, lower-dollar task-order activity. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 4 (Pennsylvania) contributes 25 awards worth $262.3 million. By potential-value ranking, the Army Materiel Command Communications Electronics Command ($250.8 million across 5 awards) and the Government Accountability Office ($151.6 million across 4 awards) are material customers but generated fewer transactions. The concentration shows a VA-centric business: 63% of awards derive from the top five customer agencies, with VISN 5 alone accounting for approximately 43% of total potential value.

Hamilton Pacific Chamberlain holds substantial vehicle authority across multiple contract vehicles. The company operates under a $300 million, five-year Multiple Award Task Order Contract with VA Veterans Integrated Service Network 5 (awarded February 2023, expiring February 2028) from which 36 task orders have been placed totaling $184.9 million. The Great American Outdoors Act MATOC—a $250 million shared vehicle with the Department of the Interior and U.S. Forest Service—has generated 50 task orders worth $27 million. National Cemetery Administration IDIQs total $49 million each across three district vehicles (North Atlantic, Continental, Pacific), with multiple awards issued across these vehicles since late 2024. The company also holds a $999.999 million Basic Ordering Agreement with the Federal Aviation Administration for design-build and bid-build construction services at Air Traffic Control facilities (awarded July 2023), a $75 million General Accountability Office construction services contract (awarded September 2022), and a $48 million USDA indefinite-delivery contract for construction and design-build projects at Washington D.C. and Beltsville, Maryland facilities (awarded August 2022). These vehicles enable task-order issuance for smaller individual projects without repeated competitive procurement, anchoring Hamilton Pacific Chamberlain's ability to respond quickly to federal facility needs across geographies and agencies.

Activity has remained steady but slightly declining year over year. The company was awarded 48 contracts in 2022, 50 in 2023, 48 in 2024, 37 in 2025, and 35 in 2026 (through late September). Total awards in the source data number 509, all prime, with no recorded subcontractor relationships. Within the next twenty-four months, 32 awards carrying combined potential value of $45.2 million reach ultimate completion, creating recompete exposure across VISN 5 delivery orders, National Cemetery Administration task orders, and Great American Outdoors Act MATOC work.

Service Contract Inventory reporting captures $215.7 million in invoiced federal services revenue across fiscal years 2022 through 2025. FY2023 invoicing peaked at $70.9 million across 212 full-time equivalents; FY2024 invoicing stood at $77.1 million across 247 FTEs; FY2025 invoicing declined to $66.9 million across 161 FTEs. The government-paid hourly rate posture spans a wide spectrum—10th percentile rates of $53.38 per hour reflect labor-intensive maintenance work, the median rate of $240.89 per hour reflects skilled trades and project management, and 90th percentile rates approaching $1,275 per hour reflect specialized medical facility renovation and engineering oversight. Across SCI-reportable prime contracts, subcontractors performed approximately 16 percent of total contractor hours on average, with 258 named subcontractors engaged across the prime footprint, indicating Hamilton Pacific Chamberlain operates predominantly as a self-performing prime while layering trade and technical services support for specialized scopes such as fire protection, Legionella control, and medical equipment installation.

Hamilton Pacific Chamberlain competes across a building-construction-heavy portfolio: 365 awards fall under NAICS 236220 (Commercial and Institutional Building Construction), with 49 additional awards under highway and bridge construction, 32 under plumbing, heating, and air-conditioning contracting, and smaller counts under facilities support and specialty trades. Public Service Commission codes show concentration in hospital maintenance (64 awards), other administrative facilities maintenance (52 awards), office building construction (47 awards), and hospital construction (44 awards), confirming the VA medical center and federal building renovation focus. The company's federal footprint spans 64 distinct customer agencies, though the VA and the Department of the Interior entities dominate both award count and dollar value.
