Basin D Sanitary Sewer Rehabilitation Project

The Basin D Sanitary Sewer Rehabilitation Project involves comprehensive repair and rehabilitation of sanitary sewer mains and laterals within San Mateo, California, utilizing advanced techniques such as CCTV inspection, cured-in-place pipe lining, pipe bursting, and open trench replacement. Work extends to manhole rehabilitation including patching, coating, and frame/cover replacement, alongside essential supporting activities like bypass pumping, dewatering, shoring, traffic control, and full site restoration of pavement, landscaping, and private improvements. All work must comply with industry standards including ASTM D543, D578, D638, D790, OSHA 29 CFR Part 1926, and NASSCO PACP for pipeline assessment, with materials such as HDPE pipe requiring permanent markings for size, SDR, trade name, material classification, certification basis, and production date. The project requires strict adherence to quality control systems, with inspections conducted on-site by the Engineer and Owner, though the Contractor bears full responsibility for arranging, funding, and ensuring compliance with all tests and regulatory requirements. Bids must be submitted by August 13, 2026, via BidAmerica’s portal, and the contract is administered by the City of San Mateo Department of Public Works through a representative designated as the RPR. Pricing is structured with fixed allowances for repairs of uninspected segments and site restorations totaling $1,175,000, but unit prices for major components like CIPP rehabilitation, CCTV inspection, and traffic control remain undetermined, resulting in an undefined total contract value. Evaluation of proposals considers multiple non-price factors including bidder experience, past work quality, material integrity, timeliness, safety record, insurance coverage, and pre-qualification status, indicating a trade-off selection process rather than a strictly lowest-price approach. Contractors must submit certifications for drug-free workplace compliance, California labor law adherence, non-collusion, and equal opportunity, and all financial documentation must be submitted electronically through ProCore. No explicit contract type is stated, but the structure implies a fixed-price arrangement with allowance items subject to actual field conditions. Materials must be stored and handled per manufacturer guidelines, and all submittals—ranging from test reports to payrolls and inspections—must conform to project standards and regulatory mandates without the use of federal invoicing systems or military standards.
