This Addendum No. 1 modifies the South Fontana ADA Ramps Project Phase II bid documents for San Bernardino County Public Works, Work Order H15027. The project involves the design and construction of 59 Americans with Disabilities Act-compliant ramps across multiple intersections throughout the South Fontana area, including locations on Granada Avenue, Hibiscus Avenue, Orchid Avenue, Hawthorne Avenue, Holly Drive, Manzanita Drive, and other local streets. Sealed proposals must be submitted by 10:00 AM on Thursday, September 3, 2026, via the ePro system with public bid opening viewable through goto.com. The addendum updates the project plan set, replaces specific special provisions sections (SP-1, SP-21, SP-56, SP-57, and P-4), and modifies construction specifications for various work items including asphalt concrete placement, cold planing operations, and pavement markings.

Key modifications in Addendum No. 1 include revised builders risk insurance requirements mandating comprehensive course of construction coverage without coinsurance penalties, including flood and debris flow coverage where applicable. Environmental mitigation measures must remain within disturbed areas with implementation of dust control, erosion control, and stormwater pollution prevention best management practices, with coordination through the Environmental Management Department at (909) 387-7897. Payment specifications are modified for Type A HMA (measured by ton), cold planing asphalt concrete pavement (measured by square yard), and saw cut and remove surfacing (measured by square yard with maximum depth of 0.82 feet). The addendum includes detailed technical specifications for asphalt placement with varying thicknesses (0.11 to 0.16 feet for surface courses over 0.41 to 0.71 feet base courses), thermoplastic pavement markings per Caltrans 2025 standards, and specific handling requirements for flooded excavations requiring removal of bottom eight inches of soil with replacement at 95 percent relative compaction.
