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 delivers mechanical construction, HVAC systems work, plumbing, and facility maintenance and repair services to federal agencies as a prime contractor exclusively. JL Mavila operates as a for-profit Subchapter S corporation and competes across both total small business set-asides and full-and-open federal procurement.

JL Mavila's customer concentration is extreme and deliberate. The National Institute of Standards and Technology accounts for 162 of the vendor's 339 prime awards (58% of award count) and $55.5 million of the combined potential value across all work, representing the overwhelming majority of JL Mavila's federal footprint. General Services Administration's Public Buildings Service National Capital Region is the distant second customer with 21 awards and $4.7 million in combined potential value. The remaining 16 customer agencies, including the Department of the Interior, the Department of the Navy, and the Department of the Army, account for residual work. This concentration is reinforced by JL Mavila's seat on multiple NIST mechanical construction vehicles: the vendor places 74 task orders under Indefinite Delivery Contract 50SBNB0C1010 ($1.1 million combined potential value), 51 task orders under IDC DOCSB134114CQ0047 ($5.4 million), and 46 task orders under BPA DOCSB134106V0001 ($3.1 million). The May 2026 award of an $8 million total small business set-aside mechanical construction IDIQ (award date May 6, 2026, ultimate completion May 5, 2029) with individual task orders ranging from $2,500 to $2 million anchors the current vehicle pipeline.

JL Mavila's service portfolio centers on on-campus mechanical systems work at NIST's Gaithersburg, Maryland research facility. Recent named deliverables include a $656,389.60 delivery order for exhaust scrubber replacement at the Gaithersburg facility (May 7, 2026, completion March 28, 2027), a $498,647.57 delivery order for water heater repair or replacement (April 4, 2024), a $464,349.06 delivery order for building 215 air handling unit repairs (February 7, 2023), a $234,634.92 delivery order for campus drinking fountain replacement (August 2, 2022), and a $162,333.42 delivery order for steam trap replacement (April 17, 2024). Work also includes emergency repairs such as building flooding remediation and pipe repair, ventilation system upgrades, nitrogen line installation for laboratory use, and plumbing and utility modifications across occupied research buildings.

Activity has been cyclical over the five-year window, ranging from two awards in 2022 to eight in 2023, with only two awards recorded in 2026 to date. The vendor holds 339 prime awards with combined potential value of $84.1 million and combined obligated dollars of $52.8 million (63% of potential value), drawn across 18 federal agencies. Work is categorized primarily under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors; 191 awards) and NAICS 236220 (Commercial and Institutional Building Construction; 26 awards). Recompete exposure in the next twenty-four months is minimal — one award ($656 thousand) faces ultimate completion within that window. JL Mavila has held no subcontractor role in the source award data; the vendor operates as a prime-only contractor.
