Region 3 Project Specific US24 Redcliff Arch Bridge F-11-T Rehab Design Services

The Colorado Department of Transportation (CDOT) is seeking a consultant to provide Region 3 Project Specific US 24 Redcliff Arch Bridge F-11-T Rehabilitation Design Engineering Services. The procurement is a Request for Proposals (RFP) targeting comprehensive bridge rehabilitation design for a historic 1940 steel arch bridge located near Red Cliff, Colorado. Consultants must self-perform at least 30% of the work and be prequalified with a valid Master Pricing Agreement with CDOT. The project's design phases are planned for 2026-2027, with construction targeted for 2028, and aims to improve bridge safety, remove load posting restrictions, and extend the structure's service life by 30 years while maintaining its historical significance. Proposal evaluation will be based on four key criteria: Project Team Composition & Capability (30 points), Past Experience (30 points), Approach (30 points), and Small Business Participation (10 points). Proposals are due by 12:00 PM Mountain Time on October 9, 2025, submitted electronically through BidNet Direct, with a panel meeting scheduled for October 28, 2025, potential interviews on November 12, 2025, and anticipated contract award/execution on January 16, 2026.

The contract will be awarded using a Cost Plus Fixed Fee (CPFF) method with a 0% Disadvantaged Business Enterprise (DBE) goal. The estimated construction budget ranges between $38.5 million and $57 million, with the current contract not to exceed $7,000,000. Consultants will be required to use CDOT-approved software packages and perform comprehensive tasks including structural analysis, finite element modeling, 3D photogrammetry, field surveys, and design alternatives evaluation. The project mandates extensive coordination with multiple agencies such as the United States Forest Service, Eagle County, local fire and emergency services, and utility providers. Significant environmental, archaeological, and historical preservation considerations are critical, with a focus on addressing structural corrosion in spandrel columns and pier components. The consultant must also collaborate closely with a Construction Manager/General Contractor (CM/GC) team throughout the design and preconstruction phases, ensuring full compliance with Title VI of the Civil Rights Act of 1964 and non-discrimination requirements.
