Manguiri Contracting LLC

Manguiri Contracting LLC, an economically disadvantaged woman-owned small business (EDWOSB) and SBA 8(a) program participant based in Frederick, Maryland, operates as a prime contractor delivering facility maintenance, waste management, and building renovation services to federal agencies under small-business set-asides. The firm competes predominantly under EDWOSB, 8(a), Woman-Owned Small Business (WOSB), and Total Small Business designations across its prime portfolio; all 36 awards in the source are prime contracts with no subcontract footprint.

Manguiri's capability portfolio centers on three primary service lines grounded in recent award activity. Solid waste collection and recycling dominate the base: 24 of 36 awards (67%) across NAICS 562111 (Solid Waste Collection) and PSC S205 (Housekeeping–Trash/Garbage Collection), covering refuse services at Army Reserve Command installations across the Mid-Atlantic and Northeast, valued cumulatively at roughly $1.2 million. Building and infrastructure renovation forms the second pillar: six awards (17%) in NAICS 236220 (Commercial and Institutional Building Construction) include high-value projects such as a $5.26 million removal and replacement of marble paving at Simon Bolivar Park (Department of the Interior, January 2026), a $2.69 million renovation of the USSS Doggett Building in Washington, DC (General Services Administration on behalf of Secret Service, September 2026, 8(a) sole source), a $1.12 million renovation of water features at the John Paul Jones and Taras Shevchenko memorials (Department of the Interior, March 2026, 8(a) sole source), and a $485 thousand MLK Jr Memorial Paver Project (Department of the Interior, March 2026, 8(a) sole source). Mechanical and HVAC services form the third line: two awards for equipment repair and replacement, including a $98 thousand HVAC equipment replacement at the Historic Preservation Training Center in Frederick (Department of the Interior National Park Service, August 2023) and a $855 thousand camera sanitary sewer line inspection at Fort Detrick (Department of the Army Northeast Region, November 2023, full and open).

Customer concentration tilts heavily toward National Park Service renovation work and Army Reserve refuse operations. The Department of the Interior National Park Service National Office accounts for 5 awards and $7 million in combined potential value (53% of all dollars), anchoring the vendor's highest-value work. The U.S. Army Reserve Command generates 20 awards but only $1.2 million in combined potential value (9% of dollars), reflecting the small-order-volume character of individual refuse contracts. The General Services Administration Public Buildings Service contributes 1 award worth $2.7 million (20% of dollars) for the Doggett Building project. The Department of Homeland Security Secret Service and the Department of the Army Installation Management Command Northeast Region together account for $894 thousand and $598 thousand respectively. Eleven distinct federal agencies have placed awards; the top five customers account for 83% of awards and 95% of combined potential value.

Manguiri holds a GSA Federal Supply Schedule contract (47QSMS24D007G) issued May 20, 2024, with a $475 thousand ceiling through May 19, 2029, covering Facilities Maintenance and Management services. The schedule carries eight labor categories spanning high-school education levels and hourly rates from $22.98 (Janitor) to $151.20 (Program Manager), with no security-cleared positions. This vehicle provides pre-negotiated rates for facility operations support across federal agencies government-wide and enables task-order activity beyond the defined awards in the source.

Activity has remained modest but steady. Two awards in 2022, six in 2023, seven in 2024, five in 2025, and five in 2026 show consistent pipeline without explosive growth. Eight awards with ultimate completion dates in the next twenty-four months carry combined potential value of $8.8 million, representing significant recompete exposure — notably the $2.69 million Doggett Building repair contract (due September 2027) and the $5.26 million Simon Bolivar Park marble work (due December 2026, already substantially complete by October 2026). The $13.1 million combined potential value across all 36 prime awards reflects a small vendor with specialized focus on waste services and National Park Service infrastructure work, operating entirely through small-business set-asides and maintaining zero sub-award exposure. SBA 8(a) certification runs through April 29, 2030.
