# Colorado HB 24-1143 (2024A) — Construction Bidding Cost Thresholds for Department of Transportation Projects

The act increases the monetary cost cap at or below which the department of transportation (department) may undertake public projects outside of a competitive bidding process (project cost cap) from $250,000 to $300,000. The department may thereafter annually adjust the project cost cap for inflation, defined as the annual percentage change in the United States department of transportation and federal highway administration's national highway construction cost index or a successor index, and may round the adjusted amount upward to the nearest $5,000. The department must publish this adjusted project cost cap on its website. The act also requires the department to report annually on highway maintenance projects that it completes that cost no more than the project cost cap, including reporting on efficiencies achieved by increasing the project cost cap.
