J. & L. Mavilia Incorporated

J. & L. Mavilia Incorporated, doing business as JL Mavila, is a self-certified small disadvantaged business based in Upper Marlboro, Maryland, that provides mechanical construction, HVAC systems, plumbing, and facility maintenance and repair services to federal agencies exclusively as a prime contractor. The company operates as a Subchapter S Corporation under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors), competing predominantly under total small business set-asides across its federal portfolio.

JL Mavila exhibits extreme customer concentration centered on the National Institute of Standards and Technology. NIST accounts for 167 of the vendor's 344 prime awards—58% of the total count—representing $58.4 million of the $87 million combined potential value across all federal work. The next tier of customers is substantially smaller: the General Services Administration Public Buildings Service National Capital Region holds 21 awards valued at $4.7 million, followed by the Department of Agriculture Agricultural Research Service with three awards totaling $3.9 million. The two rankings track closely, confirming NIST's overwhelming dominance both by volume and dollars. Recent representative work at NIST includes a $1.53 million delivery order for combined capital utility projects at the Gaithersburg facility (October 2026), a $656,390 exhaust scrubber replacement (May 2026), a $520,782 site effluent project (September 2026), and a $439,391 conversion of Building 101 induction units to Belimo valves with controls (October 2026).

JL Mavila holds a position on five named parent vehicles, all indefinite-delivery contracts or blanket purchase agreements. The largest by task-order count is IDC 50SBNB0C1010, from which the vendor has drawn 74 task orders valued at $1.1 million combined; NIST contract DOCSB134114CQ0047 generated 51 task orders worth $5.4 million; and NIST BPA DOCSB134106V0001 produced 46 task orders valued at $3.1 million. In May 2026, NIST awarded JL Mavila a new $8 million multiple-award indefinite-delivery contract running through May 5, 2029, set aside for total small business, authorizing task orders from $2,500 to $2 million for mechanical construction including hydronic and plumbing piping systems, air conditioning and distribution, utility metering, fire sprinkler systems, and laboratory safety equipment at the Gaithersburg campus.

The vendor's award activity shows minimal trajectory volatility: three awards in 2021, two in 2022, eight in 2023, four in 2024, and seven through October 2026. Six awards carrying combined potential value of $3.6 million reach ultimate completion within the next twenty-four months, presenting modest recompete exposure. JL Mavila operates with zero subcontractor footprint across its federal portfolio, delivering all work with internal resources. The vendor's capability portfolio centers on on-campus mechanical systems work—steam trap replacement, air handling unit repairs, water heater service, exhaust scrubber replacement, condensate line repair, nitrogen line installation, building exhaust fan replacement, and emergency facility remediation—concentrated entirely at NIST's Gaithersburg research facility with secondary exposure through GSA National Capital Region and scattered Department of Interior, Department of Navy, and Department of Army facility work.
