About 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, operations support, and construction services to federal agencies, with a portfolio concentrated in refuse collection, recycling, and building infrastructure work. The vendor competes predominantly under set-aside vehicles — 8(a) sole source, EDWOSB sole source, and total small business designations recur across most of its prime footprint, though it also wins full-and-open awards. Manguiri holds SBA certifications as EDWOSB, Women-Owned Small Business (WOSB), and 8(a) program participant through April 2030.
The vendor's capability portfolio centers on solid waste collection and recycling operations (24 of 35 awards), supplemented by building renovation, mechanical systems work, and infrastructure inspection. Representative prime work includes a $5.3 million fixed-price definitive contract awarded in January 2026 by the National Office for removal and replacement of marble paving and concrete base at Simon Bolivar Park in Washington, DC, with ultimate completion in December 2026; a $1.1 million definitive contract also from the National Office in March 2026 for renovation and rehabilitation of water features at the John Paul Jones Memorial and Taras Shevchenko Memorial on the National Mall, completing July 2026; and a $485,347 definitive contract awarded March 2026 by the National Office for the MLK Jr Memorial Paver Project, completing September 2026. Beyond high-visibility capital projects, Manguiri holds a $597,948 8(a) sole-source contract with the Secret Service providing on-site labor (three personnel) at Secret Service headquarters in Washington, DC, through February 2027, and a $855,216 definitive contract with the Army for camera sanitary sewer line inspection at Fort Detrick, Maryland. The vendor's GSA Federal Supply Schedule contract (47QSMS24D007G), awarded May 2024 through May 2029, covers Facilities Maintenance and Management services with eight labor categories spanning Janitor ($22.98/hour), Refuse Collector ($38.59/hour), General Maintenance Worker ($82.89/hour), and Program Manager ($151.20/hour) — all high-school-education roles without security-clearance requirements.
Customer concentration is bimodal. The Department of the Interior National Park Service National Office drives 68% of combined potential value ($7.1 million across five awards) despite accounting for only 14% of award count, anchored by the three high-value National Mall and memorial projects. The Department of the Army Reserve Command supplies 57% of award count (20 awards) but only 11% of potential value ($1.2 million), reflecting a high-volume, low-per-order model — multiple refuse collection and recycling purchase orders ranging from $29,865 to $99,777 at Army Reserve facilities across Pennsylvania, New York, New Hampshire, Maine, West Virginia, Delaware, and Maryland. The Department of the Army Installation Management Command Northeast Region contributes $894,000 across two awards (Fort Detrick work). The Department of Homeland Security Secret Service and GSA Federal Acquisition Service each hold one award of strategic relevance.
Activity shows growth through 2024 (seven awards) with a decline in 2025 (five awards) and 2026 (four awards through March). Six awards totaling $6.5 million in combined potential value complete within the next twenty-four months, representing significant recompete exposure — most notably the three National Mall/memorial projects and the Secret Service contract. Manguiri operates 100% as a prime contractor with no subcontract footprint across the awards in the source. The vendor's work is performed across CONUS federal installations and monuments, with administrative headquarters in Frederick, Maryland.
