Dunbar Mechanical Contractors, LLC

Dunbar Mechanical Contractors, LLC, a service-disabled veteran-owned small business headquartered in Memphis, Tennessee, delivers mechanical contracting, HVAC system installation and repair, construction, and facility maintenance services to the Department of Veterans Affairs and subordinate federal agencies as a prime contractor across 309 awards totaling $374.4 million in combined potential value. The firm operates exclusively as a prime (100% of awards) under SDVOSB set-asides on approximately 97% of its award portfolio, with NAICS codes concentrated in Commercial and Institutional Building Construction (238110, 147 awards) and Plumbing, Heating, and Air-Conditioning Contractors (238220, 89 awards).

Dunbar's customer base is heavily concentrated within the VA's Veterans Health Administration. Veterans Integrated Service Network 9 (VISN 9), which oversees VA medical centers across Tennessee and surrounding states, anchors the portfolio: 288 awards valued at $255.5 million represent 97% of the award count and 68% of combined potential value. Four awards from Veterans Integrated Service Network 17 carry $40.2 million combined potential value. The Army Corps of Engineers Engineering District Savannah placed one $49 million award. The National Park Service Southeast Region, the VA Technology Acquisition Center, and VISN 15 account for the remaining portfolio.

Capability work centers on HVAC systems repair, replacement, and emergency maintenance; mechanical infrastructure upgrades; facility construction and renovation; and general building services at VA medical facilities. Recent representative prime work includes a $12.672 million SDVOSB definitive contract (awarded November 2024) for chilled water loop replacement at Alvin C. York VA Medical Center in Murfreesboro, with completion targeted for March 2027; a $16.58 million SDVOSB definitive contract (September 2023) for integrated health center minor construction at the same facility, including demolition, general construction, mechanical, electrical, plumbing, and site utility work; a $4.678 million SDVOSB definitive contract (July 2026) for energy management system upgrade at Alvin C. York Campus; a $1.175 million Total Small Business definitive contract with the USDA Cotton and Tobacco Program (August 2023) for replacement of major HVAC equipment at agency headquarters in Memphis; and multiple $850,000–$917,000 delivery orders for chiller replacements, HVAC upgrades, and facility construction at Tennessee Valley Healthcare System locations.

Dunbar operates under two primary VA IDIQ vehicles. A $45 million Multiple Award Task Order Contract (MATOC) for Construction, Repair and Renovations at Tennessee Valley Healthcare System, awarded September 30, 2024 with performance through September 29, 2029, carries a 100% SDVOSB set-aside designation; recent task orders issued under this vehicle include a $1.472 million delivery order (January 2025) and a $402,684 delivery order (September 2024). A $40 million IDIQ construction contract under the Memphis VA Medical Center MATOC parent vehicle, awarded August 20, 2021 with completion through August 19, 2026 and reserved for SDVOSBs, provided a $262,718 Electronic Health Record Modernization delivery order (September 2022) and additional facility maintenance task orders. Two additional IDIQ vehicles carry 29 task orders ($11.5 million combined) and 22 task orders ($13.9 million combined), respectively, under VA contracting.

Activity has grown incrementally — 16 awards in 2022 rising to 30 awards in 2024, then moderating to 21 in 2025 and 17 in 2026 year-to-date. Seven awards with ultimate completion dates in the next twenty-four months carry combined potential value of $17.9 million and face recompete. Dunbar generates no subcontractor revenue; the firm delivers work in-house and does not appear as a subcontractor to other primes in the source material.

SCI-reported invoicing on federal service contracts above the $150,000 threshold totaled $24.3 million across FY2023–FY2024 (FY2022 shows no SCI-reportable activity). The dataset reflects $9.5 million invoiced in FY2023 and $14.8 million in FY2024, corresponding to approximately 18.6 and 18.4 FTEs respectively on SCI-captured prime contracts. Government-paid hourly rates on SCI-reported work span from a 10th percentile of $33.77/hr to a median of $373.45/hr to a 90th percentile of $4,371.26/hr, with the wide spread reflecting a mix of field labor, project management, and fixed-price construction delivery models. SCI captures only a subset of Dunbar's total federal services footprint; the vast majority of the firm's contract portfolio consists of fixed-price construction and maintenance delivery orders outside the SCI reporting threshold or in goods and equipment procurement.
