How to Find & Win Department of Transportation (DOT) Contracts
Quick Answer
To win contracts with the Department of Transportation (DOT), you must register in SAM.gov, meet CMMC cybersecurity standards (where applicable), identify opportunities via SAM.gov or agency forecasts, and submit a compliant proposal. Aligning with an expert bidding partner can significantly increase your win rate.
Understanding DOT Procurement
DOT is responsible for federal regulation and funding of most modes of U.S. transportation, with FY2025 enacted funding of approximately $152 billion. The department is organized into Operating Administrations: FAA, FHWA, FTA, FRA, FMCSA, MARAD, PHMSA, and NHTSA. DOT's procurement priorities center on infrastructure investment under the Bipartisan Infrastructure Law, aviation system modernization, and highway safety technology.
How DOT Buys
DOT procurement uses extensive IDIQ contracts for research, engineering, and IT services. The Volpe Center issues task order contracts for transportation research across all modes. FAA acquisitions follow the Acquisition Management System (AMS) rather than standard FAR procedures. Many DOT contracts require specialized certifications in engineering, safety, or transportation fields.
