The Department of Transportation's Federal Highway Administration (FHWA) intends to negotiate a sole source purchase order for a Messring Propulsion System Control Computer and Remote Braking System, essential for the Federal Outdoor Impact Laboratory (FOIL) at the Turner-Fairbank Highway Research Center. This procurement aims to replace critical components of the existing Messring propulsion system, which have become obsolete due to recent network security upgrades that rendered them incompatible with the updated infrastructure. The integration of these new components is crucial for maintaining the functionality of the highly customized FOIL test system, which relies on proprietary Messring hardware and software. Interested parties who believe they can meet the requirements and ensure seamless integration must submit their capability statements by May 29, 2025, at 12:00 AM Eastern Time, to Jerrett Solven at jerrett.solven@dot.gov.
