This is a bid sheet for the River View Sewer Improvements project issued by the Town of Gypsum, Colorado, involving the installation of approximately 3,000 linear feet of 24" sewer express line and an 8" raw water pumpback line through the Eagle River Estates neighborhood. The project is scheduled with a mandatory pre-bid meeting on May 8, 2025, at 2:00 PM, and bid opening on May 20, 2025, at 9:00 AM. The Town Council will select the winning bidder on May 27, 2025, with a notice to proceed upon contract document completion. The project requires work to be completed by September 19, 2025, with full acceptance and two-year warranty start by September 26, 2025.
