The project involves replacing an existing 2-span rubble arch culvert with a single-span, prestressed concrete slab bridge measuring 52'-7" long and 51'-0" wide, including comprehensive channel stabilization, armoring, and sidewalk tie-ins. Qualified highway contractors must be familiar with Colorado Department of Transportation's Specifications for Road and Bridge Construction and capable of executing a complex infrastructure project with multiple technical requirements. The pre-bid meeting is scheduled for September 11, 2025, at 2:00 PM (MT), with a virtual attendance option, and questions must be submitted by September 16, 2025, at 10:00 a.m. (MT).

The project scope includes utility coordination, environmental protection, migratory bird and prairie dog management, and specific construction methodologies for bridge removal, temporary water diversion, and infrastructure improvements.

The contract is subject to the Keep Jobs in Colorado Act, which mandates 80% Colorado labor on public works projects. Bidders must comply with equal opportunity employment guidelines and provide appropriate insurance documentation. The county reserves the right to require the apparent low bidder to submit a Statement of Qualifications and may reject bids from unqualified contractors. While specific set-aside designations for disadvantaged enterprises are not explicitly detailed, the procurement emphasizes local workforce participation. The total project budget appears to include a force account item of $242,395 for minor contract revisions, with the complete project estimated to be completed within 120 working days. Utility coordination will involve multiple entities including City of Loveland, Comcast, Xcel Energy, and the Greeley Loveland Irrigation Company (GLIC), with specific responsibilities outlined for both the contractor and utility owners. The geotechnical report recommends a deep foundation system bearing in underlying bedrock, with specific guidelines for driven H-piles or drilled shafts, suggesting a technically complex infrastructure renewal project.
