The Unit 2 Phase 5-2 Liner Construction Project at the San Timoteo Sanitary Landfill in San Bernardino County, California, is a public works solicitation managed by the Department of Public Works Solid Waste Management Division. The scope of work involves the construction of base and slope liners, subgrade preparation, LCRS pipes, concrete channels, and perimeter roads, as well as clearing, grubbing, and asbestos cement pipe abatement. The project requires a contractor with a State Contractor A License and mandates adherence to the 2024 Standard Specifications and Plans for Public Works Construction and Caltrans standards. Key deliverables include approved record drawings, and the project is subject to rigorous inspection by the County and a third-party Construction Quality Assurance firm, with specific acceptance criteria for geomembrane materials. The contract performance period requires work to commence within ten working days of the Notice to Proceed, with final completion expected within 350 working days. Bidders must provide performance and labor/material bonds equal to 100 percent of the contract sum and comply with California prevailing wage requirements. The solicitation process includes mandatory pre-bid meetings and job walks requiring specific personal protective equipment. Bids are submitted via the ePro electronic procurement system or in person, and evaluation is based on licensing, project history, and the completeness of the bid package. Recent addenda have modified the bid opening dates, updated technical specifications for earthwork and pavement, and introduced a Paleontological Resources Impact Mitigation Plan.
