Addendum No. 1 for the Blue River Wastewater Treatment Plant (BRWWTP) Centrifuge Replacement Project, issued by the Silverthorne-Dillon Joint Sewer Authority, modifies the original bidding and contract documents. The addendum changes the bid submission method from physical sealed bids to electronic PDF submissions to BRWTP@silverthorne.org, with the bid deadline remaining July 18, 2023, at 2:00 PM. The project involves replacing centrifuges at the wastewater treatment plant, with revised milestone dates for demolition and installation of two centrifuges, including specific start and completion dates between August and October 2023.

The addendum updates the contract's liquidated damages schedule for missed milestones, with penalties ranging from $1,000 to $10,000 per day depending on the specific milestone not met. The changes include adjusting the demolition and installation timelines for the first and second centrifuges, with new milestone dates for beginning demolition, completing installation, and starting demonstration of each centrifuge. The modifications aim to provide more precise scheduling and clearer expectations for the contractor's progress throughout the project.
