Rockridge Pump Station Replacement Re-Bid

The City of Durango is seeking qualified contractors to perform the Rockridge Pump Station Replacement project (Project #1159), a comprehensive water infrastructure upgrade located near 2614 Borrego Dr in Durango, Colorado. The procurement involves furnishing and installing a factory-built booster pump station, salvaging the existing pump station for future city use, and implementing critical infrastructure improvements including a backup generator, new pipelines, gate valve installations, security fencing, communication and electrical conduits, and an electrical panel array. The project has stringent performance requirements, specifically mandating that the pump station can only be shut down for a maximum of 5 hours during the transition from the existing to the new station. A non-mandatory pre-bid conference is scheduled for November 4th, 2025, at 1:00 p.m., with electronic bids due on December 9th, 2025, at 3:00 p.m. local time through Rocky Mountain E-Purchasing. Bidders must submit electronic copies, provide a list of subcontractors, include a 5% Bid Bond, and demonstrate experience with similar municipal water infrastructure projects. The project is estimated to commence on April 6th, 2026, with a completion date of August 8th, 2026, spanning 125 calendar days.

The contract opportunity does not explicitly outline specific set-aside designations for disadvantaged businesses, though the City of Durango does indicate a local and regional bidder preference system, where local bidders may receive a 5% preference up to $100,000 and regional bidders a 3% preference up to $40,000. The estimated construction cost is $1,110,600, with the project requiring comprehensive insurance coverage and compliance with City of Durango purchasing policies. Bidders must provide performance and payment bonds, and the City reserves the right to reject any or all bids. The new pump station will integrate with the City's existing SCADA system, utilizing ClearSCADA software and standard communication protocols. The infrastructure will include a Cummins 250 kW diesel generator with a 500-gallon sub-base fuel tank, three Cornell Pump Company close-coupled end suction pumps, and a sophisticated control panel designed by Logical Systems, LLC. The project emphasizes system integration, redundancy, and compatibility with existing municipal water infrastructure standards.
