Janicke GBR Ingenieurbüro FÜR Umweltphysik

Janicke GBR Ingenieurbüro FÜR Umweltphysik, a German-based for-profit partnership, operates as a sole-source prime contractor delivering aircraft-specific air quality modeling and airport emissions analysis to the Department of Transportation's Immediate Office of the Secretary. The vendor holds exclusive access to the proprietary LASPORT modeling platform, a nonlinear chemistry and aircraft exhaust simulation tool required by the FAA and the Committee for Aviation Environmental Protection for airport-specific air quality dispersion analysis. All four recent federal awards are firm-fixed-price purchase orders, none set-aside, issued under NAICS 541620 (Environmental Consulting Services) and PSC B502 (Special Studies/Analysis-Air Quality).

The vendor's federal footprint remains highly concentrated and narrow. Four prime awards across a four-year span (2023–2026) total $151 thousand, with one hundred percent of awards flowing from the Department of Transportation's Immediate Office of the Secretary. Recent work includes a $40.25 thousand purchase order awarded June 12, 2026, for LASPORT analysis supporting nonlinear chemistry and aircraft exhaust modeling enhancements for an unspecified airport with performance through March 31, 2027; a $38.64 thousand order from May 20, 2025, for Boston Logan International Airport air quality modeling; a $42 thousand order from January 16, 2024, for Los Angeles International Airport Phase IV assessment; and a $30.24 thousand order from March 30, 2023, for LAX Phase III assessment. The vendor has no subcontract footprint in the source data and does not sit on any parent vehicles or IDIQs. Activity is flat at one award per year. One award (the June 2026 purchase order, $40.25 thousand) reaches ultimate completion within the next twenty-four months and faces recompete exposure. The vendor operates from Hermann-Hoch-Weg 1, Überlingen, Germany, with all performance conducted in Germany.
