About this file
This is a Bid Tab document for Boulder County Parks & Open Space Department's Niwot Loop Concrete Bridge Approaches project located at 7901 Mineral Road, Niwot, Colorado. The project addresses unsustainable crusher-fines approaches to two bridges that require concrete improvements to ensure proper drainage, long-term trail sustainability, and improved accessibility. The work is organized into four main bid sections: Mobilization (including emergency management planning, FODS track-out control, asset transportation, temporary fencing, sediment control, restroom facilities, concrete washout bins, and demobilization); Concrete Bridge Approaches (including subgrade preparation, aggregate base course, concrete placement for two bridges totaling 24 cubic yards, trail edge grading, riprap, and bedding materials); Proctor Testing Reports for 95% standard compaction verification on three locations; and Compressive Strength Concrete Testing Reports for CDOT Class B concrete at both bridge locations. The document also includes three alternative bid items addressing scenarios where existing subgrade fails to meet 95% Proctor requirements, including options for six-inch compacted class road base, excavation and off-site haul, and additional Proctor testing.
Bidders must provide unit prices and total costs for all line items, with the contractor responsible for verifying material estimates. All pricing must be exclusive of federal or state taxes, as Boulder County is tax exempt. The bid tab requires completion of company name, submitting person's name and title, signature, and date from the bidder. No specific pricing guidance, set-asides, incumbent information, or funding source details are provided in this document. Bidders are directed to Boulder County's procurement website for submittal instructions and additional project information.
