Boulder County Public Works is soliciting bids for the manufacturing and delivery of an 8-foot wide by 4-foot-high precast concrete box culvert to be installed at N. 119th Street where the road crosses the Leggett Ditch. This procurement, identified as Bid Number BID-207-25, requires qualified contractors to provide a comprehensive solution including the precast concrete box culvert, watertight joints, engineering shop drawings, load rating, independent design check, and delivery. The bid specifications mandate that contractors be authorized to do business in Colorado and provide a current Certificate of Good Standing. Contractors must submit detailed documentation including a project schedule, vendor information form, completed bid tab, insurance certificate, and 2025 W-9. The bid opening is scheduled for October 10, 2025, at 3:00 p.m. and will be conducted virtually through Microsoft Teams, with a specific delivery window for the culvert between February 27 and March 3, 2026. The project requires careful coordination with Boulder County's Road Maintenance Division, with potential road access restrictions at the delivery site.

The solicitation does not explicitly indicate specific set-aside designations or restrictions for disadvantaged enterprises. Insurance requirements are detailed in Exhibit A, mandating contractors obtain Commercial General Liability insurance with minimum coverage of $1,000,000 and a $2,000,000 General Aggregate, along with Workers' Compensation, Professional Liability, and Riggers Liability insurance. The project is based on engineering plans for the North 119th Street over Leggett Ditch Minor Structure Replacement, with funding apparent through Boulder County Public Works. While specific budget ranges are not directly stated, the project involves infrastructure replacement with precise engineering specifications. Contractors must be prepared to navigate complex site conditions, including potential utility relocations and coordination with the Leggett Ditch Company. Payment for the project will be made in one lump sum upon successful delivery, inspection, and acceptance of the precast concrete box culvert by the county, with the total project scope involving structure excavation, backfill, and associated roadway improvements.
