Administration Building Basement Weatherproofing

The Cosumnes Community Services District is soliciting sealed bids for contract PC-27-010 to perform weatherproofing and subsurface drainage improvements at the Administration Building basement and associated crawlspace areas in Elk Grove, California. The project aims to reduce hydrostatic pressure and minimize groundwater intrusion through the installation of exterior subsurface drainage systems, including excavation, shoring, and backfilling. Key deliverables include the installation of sump pump systems with controls and discharge piping, the extension of roof gutter and downspout systems to direct stormwater away from the foundation, and the installation of an interior basement floor drain and secondary sump pump. The contractor is also responsible for the restoration of all disturbed surfaces and must coordinate activities with building occupants and an adjacent Montessori school. The estimated construction cost is 210,000 dollars, which includes a 10,000 dollar allowance for unforeseen site conditions. The contract will be awarded to the lowest responsive and responsible bidder. Bidders must provide bid security of at least 10 percent of the base bid and, upon award, furnish performance and payment bonds for 100 percent of the construction price from a California admitted surety insurer. Compliance requirements include adherence to Sacramento County prevailing wage rates, registration with the Department of Industrial Relations, and certification as an equal opportunity employer. Payment is structured monthly for projects exceeding 30 calendar days, or upon completion for shorter durations. Final acceptance is contingent upon required testing, inspections, and District approval.
