About the company
Diversified Site Services LLC, a Service-Disabled Veteran-Owned Small Business headquartered in Merrimack, New Hampshire, operates as a prime contractor (100% of awards) delivering construction, renovation, facilities maintenance, and grounds services to the Department of Veterans Affairs and other federal agencies, predominantly under SDVOSB set-asides. The company is a self-certified small disadvantaged business and veteran-owned enterprise with a limited liability company structure.
Diversified Site Services' capability portfolio centers on concrete facilities work: HVAC installation and repair, plumbing and pipefitting, building demolition and abatement, electrical work, steam system repairs, mechanical infrastructure upgrades, grounds maintenance, and specialty projects including cleanroom construction and lightning protection systems. Representative work includes a $3.6 million delivery order (May 2026) under the VISN 1 New England Healthcare System Construction MATOC for comprehensive construction modifications across VA medical facilities in six New England states; a $1.8 million definitive contract (March 2025) for renovation of a skilled-care vestibule and patio at VA Medical Center Brockton with unforeseen electrical and structural corrections; a $1.5 million purchase order (September 2022) for steam trap replacements across West Haven and Newington VA Medical Centers in Connecticut; and a $1.2 million contract (October 2022) to construct a three-sided emergency management infrastructure structure at Gulf Coast Veterans Health Care System in Biloxi, Mississippi.
Customer concentration is heavily concentrated in the VA ecosystem. The top five customer agencies (measuring by award count) account for 86% of recent awards, with Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 1 dominating at 61 awards worth $124.9 million combined potential value, followed by the Department of Veterans Affairs National Cemetery Administration at 31 awards worth $3.7 million, and smaller VISN footprints (VISN 6, VISN 2, VISN 8). By dollar magnitude, concentration diverges significantly: VA Technology Acquisition Center anchors $1 billion in potential value through a single $1 billion multiple-award MATOC awarded December 2025 for VISN 1 construction services, and the Army Materiel Command Research Development and Engineering Command contributes $99 million through a single multiple-award IDIQ awarded April 2026 for real property maintenance and construction at Natick Soldier Systems Center. Outside the VA, Diversified Site Services holds contracts with the Federal Aviation Administration (HVAC and roof repair at Norwood Memorial Airport, $336,965), the Air Force (waterline and fixture replacement at New Boston Space Force Station, $853,300), and the Army Reserve Command (grounds maintenance at Devens Correctional Facility, $75,167).
Vehicle position is anchored by VA indefinite delivery contracts. Diversified Site Services holds four major IDIQs: the $1 billion VISN 1 Construction MATOC (December 2025, 2025-2030, multiple-award SDVOSB set-aside) with 13 task orders totaling $8.4 million in potential value; a $100 million VISN 1 multiple-award IDIQ (October 2024, 2024-2029, SDVOSB set-aside) covering healthcare facility construction, maintenance, and repair with substantial task order activity since award; a $99 million Army RDECOM multiple-award contract (April 2026, 2026-2034, small business set-aside) for facility maintenance and alterations at Natick; and a $836,422 single-award National Cemetery Administration IDIQ (May 2026, 2026-2031) for grounds maintenance at Fort Devens Cemetery Base. Below these, Diversified Site Services operates a $5 million plumbing BPA (January 2025, VISN 1, single-award SDVOSB set-aside) with 12 task orders through 2030, and a $350,000 door repair BPA (December 2025, VISN 1, single-award, no set-aside) with multiple calls issued. Task order volume across identified vehicles totals 26 orders under one IDIQ, 13 under the VISN 1 Construction MATOC 2024-2029, and 13 under one blanket purchase agreement.
Activity trajectory shows volatile but rising volume. Awards per year climbed from 18 in 2022 to 35 in 2025 (the highest year in the data), before moderating to 24 in 2026 year-to-date. Combined potential value across all 123 awards stands at $1.29 billion, though obligated dollars total only $37.8 million (3% of potential). Recompete exposure in the next twenty-four months includes nine awards with combined potential value of $6.7 million, representing moderate near-term renewal risk.
SCI-reported service-contract activity (federal contracts above the $150,000 threshold) shows $30.1 million invoiced across FY2022–FY2025, with FY2023 at peak invoicing ($11.4 million across 21.6 FTEs). The FTE trajectory is volatile—rising to 21.6 FTEs in FY2023, then declining to 5.0 FTEs in FY2024 before recovering to 9.9 FTEs in FY2025—reflecting uneven utilization across large projects. Government-paid rates on SCI-reportable prime contracts span a wide spectrum: median around $436/hr, with senior labor pricing through $1,638/hr on high-value projects and lower-skill work at $53/hr. Across SCI-reportable prime contracts, subcontractor hours account for only 2% of total contractor hours, indicating Diversified Site Services builds its own delivery teams and self-performs the vast majority of work. One named subcontractor appears in the SCI dataset, confirming the vendor operates primarily as a self-performing prime rather than a teaming vehicle.
Diversified Site Services' federal posture is predominantly set-aside: SDVOSB set-asides dominate the prime footprint, with recent awards across Total Small Business and full-and-open competitions representing a smaller share. The vendor competes almost exclusively under SDVOSB and small-business set-asides, with only a handful of full-and-open awards (Federal Aviation Administration, Air Force). Top NAICS categories center on landscaping services (33 awards), commercial and institutional building construction (31 awards), and plumbing, heating, and air-conditioning contracting (31 awards), mirroring the concrete scope of work. The vendor maintains no recorded subcontract footprint—all 123 awards are primes, and no sub-award relationships are documented in the source.
