Countywide Culvert Repair and Replacement

The County of San Diego, Department of Public Works, is soliciting bids for a countywide culvert repair and replacement project under solicitation number 20260722043, with a response deadline of August 20, 2026. The work encompasses the installation, repair, or replacement of various drainage structures including reinforced concrete pipes (RCP), corrugated steel pipes (CSP), catch basins, headwalls, and inlets across multiple locations in Supervisorial Districts 1 through 5. Scope includes associated earthwork, minor hot mix asphalt and concrete work, traffic control, and full site restoration to original conditions. All work must adhere to the 2015 California Department of Transportation Standard Specifications, County Design Standards, and applicable state regulations including those from the California Air Resources Board. Performance is to be completed on-site at designated locations such as West Fig Street, Gunn Stage Road, and Via Loma Vista, with final as-built documentation due within 30 days of project completion. Contractors must submit detailed schedules, comply with federal-aid requirements, and ensure all materials meet specific durability standards including UV stability, moisture resistance, and structural integrity per ASTM, AASHTO, and ANSI/SCTE 77 standards. The contract requires strict compliance with workforce and safety regulations including the designation of an Equal Employment Opportunity Officer, mandatory EEO training for supervisors, and a 30% minimum self-performance threshold, prohibiting contractors from subcontracting more than 70% of the work. All subcontracts must include Form FHWA-1273 to ensure flow-down of federal-aid provisions, and contractors must certify they are not debarred or suspended from federal programs. Safety plans, lobbying certifications, and public disclosure of campaign contributions related to change orders are mandatory. Inspection and acceptance occur on-site by the County Engineer or designated representative, with acceptance criteria enforced through field testing and laboratory analysis for concrete, asphalt, aggregate, and other materials. The project is funded under a $6.25 million budget ceiling, though no unit prices or contract value are specified in the solicitation, indicating a competitive bid process without pre-established pricing. Proposals must be submitted electronically via the County’s BuyNet portal or in person by the deadline, using only official County forms and accompanied by required certifications, bid security, and subcontractor designations. Eric Ayres of the Department of Purchasing and Contracting serves as the Project Contracting Officer, while Leanne Crow
