Leonid S Chekin

Leonid S Chekin, a sole proprietorship based in West Springfield, Virginia, provides language services—interpretation, translation, training, and consulting—to the Department of State as a prime contractor operating exclusively in full-and-open competition with no set-aside designations across its federal footprint. All 71 awards in the source data are prime contracts; the vendor does not subcontract.

Chekin's customer concentration is extreme and single-agency: the Department of State accounts for 65% of awards by count and 89% of combined potential value across the entire portfolio. The Department of State Bureau of Administration dominates with 40 awards valued at $986 thousand combined potential value, followed by a small number of awards from the main Department of State entity ($48 thousand), the Department of Commerce ($3 thousand), and the Department of State Office of Language Services. The vendor has served four distinct customer agencies in recent years.

Work is performed in Washington, DC and delivered through blanket purchase agreement call orders under five active BPA IDVs. The largest current vehicle is BPA 190PRL25A0060, a $250 thousand ceiling BPA awarded October 1, 2024 running through September 30, 2025, with eight task orders placed to date totaling $77 thousand in combined potential value. Prior BPA IDVs include a $150 thousand ceiling BPA (190PRL24A0060, October 2023–September 2024; 7 task orders, $42 thousand), another $150 thousand BPA (190PRL23A0060, October 2022–September 2023; 8 task orders, $52 thousand), a $100 thousand BPA (190PRL22A0060, October 2021–September 2022; 6 task orders, $40 thousand), and a Basic Ordering Agreement SOPRLS05G5413 with 7 task orders valued at $38 thousand. Representative task orders include a $16.3 thousand language-services call from the Bureau of Administration awarded October 1, 2025 completing September 19, 2026; a $15.5 thousand language-services call from the Bureau completing April 3, 2026; and a $14.3 thousand call from the Bureau completing October 25, 2025.

Activity has declined over the past five years—from seven awards in 2021 to four in 2025—with one award (combined potential value $16 thousand) reaching ultimate completion within the next twenty-four months and therefore facing recompete. Combined dollars obligated across all awards total $521 thousand, representing 44% of combined potential value. All work falls under NAICS Translation and Interpretation Services (71 awards) and PSC Support–Administrative: Translation and Interpreting (71 awards). The vendor's federal portfolio spans from October 2004 to October 2025, indicating sustained engagement with State Department language procurement over two decades, though recent award volume and dollar velocity have declined.
