About Holmes Mechanical Contractors, LLC

Written by GovTribe AI ·

Holmes Mechanical Contractors, LLC, a Capitol Heights, Maryland-based minority-owned, veteran-owned small business, operates as a federal prime contractor exclusively under SBA set-asides, delivering mechanical systems work, facility infrastructure upgrades, and construction services to civilian federal agencies in the National Capital Region. The firm holds dual SBA certifications as an 8(a) Business Development Program participant (expiring June 8, 2026) and a Service-Disabled Veteran-Owned Small Business (expiring June 8, 2027), and competes exclusively through 8(a) Sole Source and small-business set-aside vehicles.

Holmes Mechanical's federal footprint concentrates in facility maintenance and mechanical infrastructure work. Across 34 prime awards in recent years, the firm has secured work spanning commercial and institutional building construction (15 awards), facilities support services (7 awards), and plumbing, heating, and air-conditioning contracting (6 awards). The National Capital Region anchors the customer base: GSA's Public Buildings Service National Capital Region leads by award count (16 awards, $5.6 million combined potential value), followed by the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 5 (3 awards, $5.1 million) and the Department of Homeland Security's U.S. Secret Service (3 awards, $1.9 million). When ranked by potential value, a GSA Federal Acquisition Service position surfaces as a significant vehicle with $12.1 million potential, paired with the GSA Public Buildings Service National Capital Region customer relationship. The top five customer lines account for 79% of awards and 96% of combined potential value, reflecting heavy concentration in executive-branch facility operations.

Recent prime contract examples illustrate the scope: a $1.83 million 8(a) Sole Source definitive contract from the Defense Information Systems Agency (awarded December 17, 2025) for HVAC cooling upgrades to three sections of the Eisenhower Executive Office Building; a $1.13 million 8(a) Sole Source contract from the U.S. Secret Service (awarded November 17, 2023) for HVAC system replacement in the New Executive Office Building locker room; and a $78,448.75 8(a) Sole Source definitive contract from the Office of Administration (awarded February 2, 2026) for the West Wing Valet Pantry Refresh at 1600 Pennsylvania Avenue. Holmes Mechanical also holds a $5 million blanket purchase agreement with Veterans Integrated Service Network 5 (awarded March 18, 2026) for mechanical services, maintenance, repair, replacement, and demolition work on plumbing, HVAC-R, electrical, and control systems at the Washington, DC Veterans Affairs Medical Center, running through March 1, 2031 with individual task orders estimated at $10,001 to $100,000 per order.

Award activity has accelerated recently — one award in 2022, growing to four in 2025 and three in 2026 through April — though four awards (combined potential value $2.1 million) face completion within the next twenty-four months and therefore recompete exposure. Combined potential value across all 34 awards stands at $28.5 million, with $11.1 million obligated to date. SCI-reported invoiced revenue on federal service contracts above the $150,000 threshold totaled $2.1 million in FY2022 (the only year in the SCI dataset with prime invoicing), with a median government-paid hourly rate of $785.83 per hour across reported contract work. Holmes Mechanical operates exclusively as a prime contractor across its federal portfolio, with no subcontract activity in the recent award set, and the firm delivers work with its own labor force rather than through subcontractor teaming. The vendor's work is confined to facilities and mechanical systems — no IDV vehicles, GWACs, or agency-wide master vehicles appear in the portfolio, and task-order activity flows primarily through agency-level BPAs and the GSA Multiple Award Schedule.
