L Street Backflow Preventer Project

The L Street Backflow Preventer Project is a public works procurement issued by the Sweetwater Union High School District in Chula Vista, California, under Bid #26-2969-DP. The project involves replacing backflow preventers at three specific locations: 650 L Street, 640 L Street, and 642 Arizona Street. Contractors are required to furnish all labor, materials, equipment, and supervision to install new N-Style Fire Service Backflow preventers, which includes obtaining necessary permits, performing inspections, and modifying infrastructure to complete a turnkey project at each site. Qualified bidders must hold a Class A or C-16 California State Contractor's License and be registered with the Department of Industrial Relations (DIR). The project has a mandatory site walk scheduled for September 30, 2025, at 8:30 a.m., with bid submissions due on October 16, 2025, by 11:00 a.m. The contract period runs from November 22, 2025, through April 30, 2026, with the district reserving the right to award the contract to the lowest responsible, responsive bidder.

The procurement has specific requirements for contractor participation, including a 10% bid security and mandatory DIR registration for all contractors and subcontractors. Subcontractors performing more than 0.5% of the work must be explicitly listed in the bid documentation. The project includes an allowance of $30,000 to cover potential unanticipated concealed existing conditions. Environmental health and safety compliance is mandatory, with contractors required to adhere to OSHA standards and maintain a safe, clean work area. While no specific set-aside designations for disadvantaged enterprises are mentioned, the bid emphasizes prevailing wage requirements and comprehensive safety protocols. The project focuses on infrastructure improvement and water system safety, utilizing existing site infrastructure and requiring careful integration of new backflow prevention systems. Though a precise budget is not specified, the $30,000 allowance suggests a project value likely in the range of $150,000 to $250,000, depending on the complexity of the installation and any unforeseen site conditions.
