Toxcel LLC

Toxcel LLC, a small disadvantaged business sole proprietorship based in Gainesville, Virginia, provides transportation safety research, human factors engineering, and behavioral safety training to the Department of Transportation's modal administrations as a prime contractor on 95% of its federal awards. The vendor operates across research and development, professional training delivery, and technical consulting services, competing predominantly in full-and-open procurements under small-business designation where applicable.

Toxcel's customer footprint is highly concentrated within DOT. The National Highway Traffic Safety Administration (NHTSA) anchors the portfolio with 64 awards valued at $176.3 million combined potential value; the Federal Highway Administration (FHWA) holds 56 awards at $83.2 million; and the Federal Motor Carrier Safety Administration (FMCSA) accounts for 9 awards at $118.9 million. These three agencies represent 100% of Toxcel's federal award count and combined potential value. NHTSA dominates both volume and dollar concentration, placing frequent smaller orders ($300K–$700K ceilings per typical delivery order), while FMCSA anchors the largest single vehicle on the portfolio—a $60 million multiple-award R&T IDIQ awarded July 16, 2026.

Toxcel's capability portfolio centers on rigorous human factors research, driver behavior analysis, and safety countermeasure evaluation. Representative prime work includes a $4.5 million FHWA delivery order (November 1, 2025) for production of Manual on Uniform Traffic Control Devices rulemaking materials; a $120 million NHTSA Human Factors IDIQ (awarded September 16, 2024, completion March 15, 2030) supporting motor vehicle safety research across automated vehicle integration, occupant protection, and pedestrian safety; a $1.7 million NHTSA Small Business set-aside delivery order (September 30, 2024) for Click It or Ticket evaluation; and a $16.972 million FHWA single-award Human Factors On-Site Support Services IDIQ (awarded July 2, 2024, completion July 1, 2029) sustaining research on automated driving systems, traffic control device development, and pavement marking analysis. Work also encompasses training program development—including FHWA-NHI course delivery on work zone management, Title VI compliance, and road safety—and behavioral safety research on distracted driving, impaired driving countermeasures, seat belt use, and pedestrian safety for vulnerable populations.

Toxcel holds five significant parent vehicles. The FHWA's $16.972 million Human Factors On-Site Support Services IDIQ (single-award, July 2, 2024–July 1, 2029) has issued 15 task orders totaling $14.1 million to date; the NHTSA Human Factors IDIQ (multiple-award, $120 million, September 16, 2024–March 15, 2030) supports ongoing research tasking; a GSA Multiple Award Schedule contract ($600K ceiling, December 17, 2021–December 16, 2031) carries 16 task orders at $5.7 million combined value and offers 12 labor categories spanning technician roles at $68.07/hr through PhD-level subject matter expertise at $311.77/hr with no security clearance requirements; the NHTSA Small Business Behavioral Safety Research Support IDIQ ($7.3 million) issues task orders under 13 recorded awards; and the FMCSA R&T IDIQ ($60 million, July 16, 2026–July 15, 2031) is a newly awarded multiple-award vehicle. These vehicles support a mix of firm fixed-price, time-and-materials, and cost-plus-fixed-fee delivery orders.

Activity has grown year over year—eight awards in 2022 to 16 in 2024, with 17 awards issued in 2026 year-to-date. Recent SCI-reportable invoicing across Toxcel's prime service contracts shows $4.3 million in FY2025 across 6.4 FTEs, up from $4.4 million in FY2024 across 4.1 FTEs; the SCI dataset captures only federal service contracts above $150,000 and excludes goods, products, and classified work, making it a partial view of Toxcel's federal services footprint. Government-paid hourly rates on SCI prime contracts cluster at a median of $299.81/hr, with senior and expert roles pricing through $1,691.71/hr at the 90th percentile. Twenty awards (combined potential value $13.4 million) reach ultimate completion within the next twenty-four months and face recompete risk.

Toxcel builds delivery capability internally—across SCI-reportable prime contracts, subcontractors represent only 2% of total contractor hours on average—with the exception of a stable relationship with Battelle Memorial Institute, to which the vendor subcontracts labor on work zone management technical assistance, multimodal policy research, and MUTCD rulemaking support. The vendor also appears as a sub-recipient on one National Academy of Sciences grant sub-award (July 15, 2024) for LED applications on traffic control devices. The vendor's prime-focused posture, concentrated customer base within three DOT agencies, and specialization in transportation safety research and human factors engineering position Toxcel as a technical resource for federal safety program advancement rather than a generalist federal contractor or feeder for larger primes.
