Qualified bidders must demonstrate extensive experience in waste management facility liner system projects, with minimum requirements including completion of at least five waste management facility liner projects within the past three years, each at least 500,000 square feet in size, and a minimum of 10 million square feet of polyethylene geomembrane installation. Personnel requirements are stringent, mandating that the installation supervisor have worked on at least two complex projects, the master seamer must have completed 5,000,000 square feet of geomembrane seaming work, and other seamers must have seamed a minimum of 1,000,000 square feet.

The project has a targeted completion time of 60 working days, with a tentative contract award date of May 30, 2023, and liquidated damages set at $5,000 per calendar day of delay.

The procurement allows for potential local and micro-business preferences, with bidders required to have a Department of Industrial Relations (DIR) Certification Number and comply with prevailing wage regulations. The project may be eligible for FEMA reimbursement, requiring bidders to have a SAM.gov Unique Entity Identifier (UEI) number. Comprehensive insurance requirements include $2,000,000 in general liability coverage, automobile liability, workers' compensation, and professional liability insurance. While no specific budget range is explicitly stated, the bid includes pricing tables for mobilization/demobilization, liner seam repair, GCL, HDPE geomembrane liner, and sandbag ballast system. The County has an Environmental Purchasing Policy that emphasizes recycled and environmentally preferable products, potentially providing additional considerations for bidders. The original liner system was installed in May 2021 by ICS, Inc. as the general contractor and Layfield Geosynthetics as the liner installer, with Geo-Logic Associates serving as the Construction Quality Assurance (CQA) firm. The project involves repairing a 32-acre side slope base liner system using specialized geosynthetic materials, including a Wind Defender TG geosynthetic ballast system and a 60 mil HDPE geomembrane with single-sided texturing.
