Digester 4 Roof Repair Project

The Sacramento Area Sewer District (EchoWater) is soliciting bids for the Digester 4 Roof Repair Project at the EchoWater Facility in Elk Grove, California. The scope of work involves cleaning and preparing the existing substrate of the Digester 4 floating cover, repairing deteriorated areas such as exposed foam and compromised coatings, and applying a spray polyurethane foam and cold fluid applied roof system. The contractor is responsible for all labor, abatement, disposal, equipment, and materials. The project is structured as a lump-sum arrangement and includes a 20,000 dollar allowance for unanticipated site conditions and spare parts. The procurement process emphasizes technical compliance with ASTM and FM standards, with a preference for California-made materials when quality and price are equal. Award may be granted to the lowest responsible bidder, though the District reserves the right to select the bid in its best interest. Key requirements include a valid California State License Board license, a noncollusion declaration, and comprehensive insurance coverage. All project administration, including invoicing and submittals of shop drawings and product data, must be managed electronically through the District's web-based Project Controls System. Performance is tracked via contract milestones and weekly working days starting from the Notice to Proceed.
