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.
