About Addon Services LLC

Written by GovTribe AI ·

Addon Services LLC, a Warren, Michigan-based women-owned small business (WOSB) and economically disadvantaged women-owned small business (EDWOSB), operates as a prime contractor delivering construction, facilities maintenance, IT support, and professional services across 57 federal agencies. The vendor competes predominantly under 8(a) and small-business set-asides; roughly 45 percent of recent awards by count carry small-business designations (8(a) sole source, competitive 8(a), total small business, partial small business, or economically disadvantaged women-owned). Addon is a minority-owned, Subcontinent Asian (Asian-Indian) American-owned limited liability company with two named subsidiaries: Addon UBT JV, LLC and Anah LLC, both joint-venture entities carrying identical SBA certifications.

Addon's federal award footprint spans construction, facilities support services, and administrative consulting. The top customer by potential value is the Department of the Army Corps of Engineers Engineering Support Center Huntsville (18 awards, $512.8 million combined ceiling), anchored by a $450 million Facilities Repair and Renewal (FRR) MATOC running through April 2027 that has issued recent delivery orders for a $29.6 million Naval Air Station North Island renovation project in California (awarded September 2025, completion April 2028), a $29.2 million minor construction project at Camp Foster, Okinawa (awarded September 2024, completion July 2026), and a $7.85 million maintenance facility at Lock 27, Illinois (awarded September 2024, completion October 2027). The Naval Facilities Engineering Command ranks second by potential value (7 awards, $346 million), driven by a $249 million PWD Maine MACC 2022–2027 contract for design-build and design-bid-build construction services and a $95 million Naval Support Activity Crane ID/IQ (awarded April 2024, total small business set-aside). The Army Installation Management Command Southwest Region accounts for 15 awards worth $103.6 million combined potential value, predominantly facilities maintenance and non-recurring work orders. The Department of the Army Michigan National Guard supplies 58 awards ($20 million combined), chiefly nurse case management and laboratory testing services under 8(a) sole-source designations. GSA Region 5 holds three awards ($53.4 million combined potential value) including a $50 million repair-and-alterations indefinite delivery contract awarded September 2024 under total small business set-aside, spanning Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. By count, the top five agencies account for 45 percent of awards.

Addon sits on multiple large indefinite-delivery vehicles. The $450 million Army Corps of Engineers FRR MATOC dominates recent activity, with delivery orders spanning roofing repairs, renovations, HVAC systems, and parking-lot construction at domestic and overseas installations. The $249 million Naval Facilities Engineering Command PWD Maine MACC supports construction and renovation services in Maine through June 2027, with recent orders totaling roughly $3.75 million. The $250 million Department of Interior Fish and Wildlife Service design-build MATOC (awarded March 2023, completion April 2028, total small business set-aside) has issued a $10.14 million delivery order for visitor center construction at Seney National Wildlife Refuge in Michigan (awarded September 2022, completion July 2026). The $95 million Naval Facilities Engineering Command Naval Support Activity Crane ID/IQ (awarded April 2024, total small business set-aside, completion September 2028) supports design-build and design-bid-build construction across Indiana. The $50 billion 8(a) STARS III Government-Wide Acquisition Contract (awarded February 2022 under competitive 8(a), expiration July 2026) positions Addon for IT and professional services orders across civilian agencies. A $50 million GSA Region 5 repair-and-alterations indefinite delivery contract (awarded September 2024, total small business set-aside, completion November 2026) covers facility renovations and systems work across the Midwest. Addon also holds a $24.9 million Army Corps of Engineers facilities maintenance MATOC (awarded September 2025, competitive 8(a), completion September 2025), though the completion date suggests this vehicle is nearing expiration. The vendor operates a basic ordering agreement with Army Sustainment Command for Eagle Logistics Support Services (awarded February 2026, completion July 2027, zero ceiling value pending orders).

Recent award activity has declined sharply: 32 awards in 2022, 18 in 2023, 12 in 2024, and only 5 in 2025 and 2 in 2026 (through April). Fourteen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $91.1 million, representing significant recompete exposure. Addon's combined potential value across all 303 awards totals $51.83 billion, though only $305.4 million (1 percent) has been obligated, reflecting the prevalence of indefinite-delivery ceilings that remain unexercised. Addon operates exclusively as a prime; no subcontract activity appears in the source.

SCI-reported federal service-contract invoicing (contracts above the $150,000 threshold) totaled $24.8 million across FY2022–FY2024: $4.7 million in FY2022 (35.3 FTEs), $10.9 million in FY2023 (39.4 FTEs), and $9.2 million in FY2024 (46.1 FTEs). The FTE trajectory shows modest growth and workforce scale in the federal services arena, with 46 FTEs performing SCI-reportable work in the most recent year. Across SCI-reportable prime contracts, Addon self-performs 100 percent of hours with zero subcontractor engagement reported. On GSA Schedule labor categories, Addon offers 34 roles ranging from Information Specialist Level 1 at $62.55 per hour (high school, three years' experience) through Subject Matter Expert Level 3 at $298.09 per hour (master's degree, ten years' experience), with no security-cleared positions listed. Government-paid hourly rates on SCI contracts span a wide spectrum: 10th percentile $12.46 per hour, median $340.53 per hour, and 90th percentile $1,726.95 per hour, suggesting a mix of lower-touch administrative support, mid-level technical services, and specialized high-value consulting. The category concentration is heavily weighted toward Commercial and Institutional Building Construction (48 awards), Facilities Support Services (43 awards), and Administrative Management and General Management Consulting Services (33 awards).

Addon's set-aside posture reflects a predominantly small-business profile: the vendor qualifies across WOSB, EDWOSB, 8(a), self-certified small disadvantaged business, and minority-owned designations, and recurs in competitive 8(a), 8(a) sole source, total small business, and partial small business set-asides. The award footprint skews toward construction and facilities work under set-asides, with notable exceptions in professional services (programming and program objective memorandum support, case management, IT support) also flowing through 8(a) designations.
