Dillon Water Treatment Plant Disinfection Contact Time Improvements Project

The Town of Dillon, Colorado, located in Sedgwick County, is soliciting bids for the Water Treatment Plant Disinfection Contact Time Improvements Project through a Design-Bid-Build procurement method. The project involves comprehensive improvements to the existing ground level steel water storage tank, including selective demolition, tank repair, and alterations. Key deliverables include constructing a new process analytical building with associated piping, instrumentation, controls, and electrical work, along with a large diameter core drill for an existing below-grade vertical concrete wall, structural concrete work, and below-grade ductile iron process pipe installation. The bid documents were issued in June 2024, with electronic bids to be received via BidNet until August 8, 2024, at 2:00 PM local time. A non-mandatory pre-bid conference was held on July 16, 2024, at 10:00 AM at the Town of Dillon Water Treatment Plant. The project timeline originally specified a 180-day contract for substantial completion and 210 days for total completion, though Addendum 2 extended these to 450 and 480 days respectively. Bid questions were required to be submitted by July 29, 2024, with the bid opening scheduled for August 8, 2024, at 2:00 PM via Microsoft Teams.

No specific set-aside designations or restrictions for disadvantaged enterprises were mentioned in the contract documents. The project does not involve prevailing wages, American Iron and Steel procurement provisions, or minority usage requirements. The estimated contract will include performance, payment, and warranty bonds, with liquidated damages provisions based on the original contract amount. While no incumbent vendors were explicitly identified, the project requires integration with existing water treatment infrastructure, particularly the 0.4 MG welded steel water storage tank (Clearwell No. 2). The contract requires maintaining the water storage tank's operational status during the irrigation season from June 1 through September 15, 2025, with a goal of achieving substantial completion and an operable system by June 1, 2025. Specific budget details were not explicitly outlined in the documents, but the comprehensive nature of the project—involving civil, structural, electrical, and process modifications—suggests a significant municipal infrastructure investment. Potential bidders will need to demonstrate technical expertise in water treatment facility improvements, process piping, instrumentation, and electrical systems.
