About Diversified Site Services LLC
Diversified Site Services LLC, headquartered in Merrimack, New Hampshire, is a Service-Disabled Veteran-Owned Small Business (SDVOSB) that specializes in construction, renovation, maintenance, and grounds services for federal agencies. The company is registered in SAM.gov through October 10, 2026, and holds certifications as a self-certified small disadvantaged business, for-profit organization, and veteran-owned business operating as a limited liability company. Diversified Site Services has established itself as a trusted federal contractor with a robust track record of delivering facilities management, infrastructure repair, and construction services across multiple federal agencies, with particular emphasis on supporting the Department of Veterans Affairs healthcare system throughout New England and beyond.
The company's federal contract portfolio demonstrates extensive expertise across diverse facility management and construction disciplines. Diversified Site Services has received numerous prime contract awards from the Department of Veterans Affairs' Veterans Integrated Service Networks (particularly VISN 1, VISN 2, VISN 6, VISN 8, and VISN 9), the National Cemetery Administration, the Department of Defense (including the Air Force and Air National Guard), the National Park Service, and the Federal Aviation Administration. The scope of work encompasses plumbing and pipefitting services, HVAC installation and repair, electrical upgrades, steam system replacements, fire suppression system installation, building demolition and abatement, structural repairs, parking lot resurfacing, grounds maintenance, and specialized facility upgrades including pharmacy cleanroom installation and lightning protection systems. Contract values have ranged from modest task orders under $1,000 to major definitive contracts exceeding $1.7 million, with the majority structured as firm fixed-price awards. Many of these contracts were set aside for Service-Disabled Veteran-Owned Small Businesses, reflecting the federal government's commitment to supporting veteran-owned enterprises, while others were competitively awarded without set-aside designations. The company has demonstrated capability managing complex, multi-building renovation projects, emergency response work, hazardous materials abatement, and specialized infrastructure replacements across VA medical centers in Connecticut, Massachusetts, New Hampshire, Maine, New York, North Carolina, Florida, Louisiana, and Mississippi, as well as military installations and national parks.
Diversified Site Services currently holds four active Indefinite Delivery Contract vehicles totaling approximately $1.646 billion in ceiling value. The most recent and substantial is the VISN 1 Construction Multiple Award Task Order Contract (MATOC) for 2025-2030, a $1.0 billion multiple-award IDV awarded December 16, 2025, providing comprehensive construction, repair, and alteration services across VA medical facilities in six New England states—Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont—with project scopes ranging from $1,000 to $50 million. A companion $5 million Blanket Purchase Agreement for plumbing and pipefitting services at VA Medical Centers in West Haven and Newington, Connecticut, was awarded January 31, 2025. The company also maintains a $100 million multiple-award Indefinite Delivery Contract awarded October 9, 2024, providing construction, maintenance, and repair services for all healthcare facilities within VISN 1's New England Healthcare System through November 2029, under which numerous task orders have been issued for mechanical repairs, condensate line replacement, vestibule renovations, and oxygen tank compliance upgrades. Additionally, Diversified Site Services holds a $1.56 million single-award IDV from the VA National Cemetery Administration for complete grounds maintenance services at national cemeteries in Massachusetts, with a period of performance through January 31, 2026. A $40 million multiple-award construction IDIQ contract with the VA Veterans Health Administration for non-recurring maintenance and facility improvements across the Northeast region, awarded August 20, 2021, concluded August 19, 2025. These IDV vehicles enable the VA and other federal agencies to efficiently issue task orders for facility requirements across multiple locations, providing Diversified Site Services with flexible, long-term contracting relationships that support ongoing healthcare and cemetery infrastructure needs throughout New England and select other regions.
