Mariana MC Loughlin

Mariana MC Loughlin, a woman-owned sole proprietorship based in Arlington, Virginia, provides translation, interpretation, and language support services to the Department of State as a prime contractor on a full-and-open, non-set-aside basis. The vendor operates exclusively under blanket purchase agreements issued by the Department of State's Bureau of Administration and does not hold parent contract vehicles, sit on government-wide acquisition contracts, or subcontract to other primes.

Customer concentration is absolute: the Department of State Bureau of Administration accounts for 172 of 173 awards (99.4% of potential value), with work performed in Washington, D.C. in support of diplomatic engagement, foreign assistance initiatives, international conferences, and multilateral dialogues. A single additional award of $824 went to the Department of State proper. The vendor's entire footprint consists of firm fixed-price BPA calls ranging from $200 to $8,400 per task order, with typical durations of one to twelve months. Recent representative work includes task orders for translation and interpretation services supporting meetings with foreign governments, human rights documentation efforts, international policy forums such as the US-Mexico Cyber Policy Working Group, trafficking in persons coordination, and diplomatic event logistics. One notable task order valued at $5,835 supported logistical services for the Secretary of State's trip to Bogota, Colombia.

The vendor holds five active BPAs under the Department of State Bureau of Administration's language services acquisition framework. The current BPA (190PRL25A0099, running through September 30, 2026) carries a $250,000 ceiling and has generated 33 task orders totaling $93 thousand in potential value. Prior BPAs carried $100,000 to $150,000 ceilings: the 2024 cycle (190PRL24A0099) yielded 39 calls worth $61 thousand; the 2023 cycle (190PRL23A0099) produced 36 calls worth $54 thousand; the 2022 cycle (190PRL22A0099) generated 31 calls worth $35 thousand; and the 2021 cycle (190PRL21A0099) delivered 21 calls worth $38 thousand. Activity has been consistent across the five-year window (41 awards in 2021, 37 in 2022, 39 in 2023, 34 in 2024), though only one award has been recorded in 2025 to date. The vendor has been registered in SAM.gov since 2007 and maintains no sub-award footprint—100 percent of awards are prime.

The vendor's posture is strictly full-and-open competition with no set-aside utilization; work is categorized under NAICS 541930 (Translation and Interpretation Services) and PSC 6210 (Administrative Support—Translation and Interpreting). Combined potential value across all awards sits at $1.1 million, with $435 thousand (40%) obligated to date. The business model relies entirely on recurring BPA calls from a single customer agency, creating high customer concentration and recompete exposure tied to annual BPA renewals with the Bureau of Administration.
