General And Mechanical Services, LLC

General And Mechanical Services, LLC, an Annapolis, Maryland-based small business mechanical contractor, operates as a prime contractor (99% of recent awards) delivering HVAC, plumbing, electrical systems maintenance, and facilities repair services to federal agencies on a full-and-open, non-set-aside basis across multiple vehicle types. The company competes predominantly on civilian agency accounts rather than under SBA designations, though a minority of awards carry Total Small Business set-aside designations.

Customer concentration is heavily weighted to the National Institutes of Health. NIH Construction accounts for 42 awards (22% of the award count) with $4 million in combined potential value, followed distantly by the National Institute of Standards and Technology (12 awards, $8.5 million), GSA Public Buildings Service National Capital Region (11 awards, $5.1 million), and the Department of Health and Human Services Office of the Assistant Secretary for Administration (7 awards, $199 thousand). The top five customers by count cover 40% of all awards. By potential value, however, the portfolio is dominated by a single GSA Federal Acquisition Service vehicle anchoring $30.05 billion in theoretical ceiling—the company's $34.6 million General Services Administration Multiple Award Schedule contract (Federal Supply Schedule 47QSHA22D0002, awarded October 2021, running through October 2026). This GSA MAS is the vendor's primary federal vehicle, supporting 57 task orders worth $16.8 million in combined potential value. The vendor also holds a single-award Blanket Purchase Agreement with NIH Construction valid through April 2029 for general construction and repair projects across NIH facilities, from which 20 BPA calls have been issued ($2.2 million combined potential value). Work under these vehicles centers on HVAC and mechanical system replacements, emergency facility repairs, chiller and pump installations, and preventive maintenance at federal campuses in the Bethesda and Gaithersburg corridor and across civilian agencies.

The award portfolio spans 59 customer agencies and carries a combined potential value of $30.09 billion, though that ceiling reflects the GSA MAS placeholder structure rather than true obligated spend—combined dollars obligated across all awards total $33.5 million (less than 1% of potential value). Primary NAICS codes reflect the mechanical contractor profile: Plumbing, Heating, and Air-Conditioning Contractors dominate with 84 awards, followed by Electrical Contractors and Other Wiring Installation Contractors (56 awards) and Facilities Support Services (25 awards). PSC codes track similarly, with Repair or Alteration of Hospitals and Infirmaries (34 awards) and maintenance of refrigeration and air-conditioning equipment (25 awards) leading the work mix. Representative recent work includes a $119.7 million firm fixed-price BPA call with NIH Construction for installation of supplemental cooling and dehumidification systems in animal feed rooms (April 2026), a $2.99 million Total Small Business definitive contract with the Armed Forces Retirement Home for chiller installation services (June 2022), a $755.9 thousand GSA MAS delivery order with the Department of Labor for air handler unit repair at the Francis Perkins Building (September 2021), and a $303.3 thousand GSA MAS delivery order with GSA National Capital Region for delegated switchgear repairs (October 2022).

On the GSA Schedule, the company offers 11 labor categories spanning technician-level roles (HVAC Service Tech, Testing & Balancing Technician at $101–$104/hr with high-school education and 2 years' experience) through principal-level engineering ($268.98/hr, master's degree, 7 years' experience). No security-cleared positions are available. The rate spectrum from $76.84/hr (Word Processor) to $268.98/hr (Principal Engineer) positions the vendor to support facilities maintenance task orders across civilian agencies at both operational and design-engineering levels.

Activity has remained modest but steady. The vendor logged 15 awards in 2022, declining to 5 in 2023, then recovering to 9 in 2024 and 7 in 2025, with 4 awards so far in 2026 (through early July). Seven awards are scheduled for ultimate completion within the next twenty-four months, carrying combined potential value of $468 thousand—a minor recompete exposure. Service Contract Inventory data covering FY2022–FY2024 shows SCI-reportable invoiced revenue of $4.6 million across prime contracts ($1.1 million in FY2022, $1.9 million in FY2023, $1.6 million in FY2024), with an FTE trajectory fluctuating from 3.7 FTEs in FY2022 to a low of 0.6 FTEs in FY2023, recovering to 2.0 FTEs in FY2024. On federal services contracts captured in SCI, government-paid hourly rates ran a median of $476.74/hr, with rates ranging from $132.58/hr at the 10th percentile to $953.61/hr at the 90th percentile, reflecting a mix of technician and engineering labor across facilities maintenance tasks. Across SCI-reportable prime contracts, subcontractors performed an average of 36% of total contractor hours, with 19 named subcontractors reported over the period. The vendor also carried one active sub-award—a Facilities Investment Services preventive-maintenance and repair role under prime Stampede Ventures, Inc. (March 2025).
