This is a set of construction drawings for the Fontana Unified School District's water piping replacement project at North Tamarind Elementary School, located at 7961 Tamarind Avenue, Fontana, California 92336. The project involves comprehensive plumbing system upgrades for the Kindergarten Building C, including demolition of existing water piping infrastructure and installation of new cold water (CW) lines throughout the facility. The scope encompasses replacement of a 2-inch water valve in the yard box, capping and abandonment of existing underground water pipes, installation of new 2-inch underground water piping, and connection of new cold water lines to existing fixtures including lavatories, water closets, sinks, water fountains, and hose bibbs. The drawings also detail installation of shut-off valves, water hammer arrestors, and pressure-reducing valve stations to meet current California plumbing codes. The design was completed with a 50 percent construction document phase dated December 5, 2025, and 100 percent completion dated January 12, 2026. Bids are due no later than 2:00 p.m. on Monday, June 8, 2026, through the district's e-procurement portal, with questions accepted until 12:00 p.m. on Tuesday, May 26, 2026.

The project must comply with the 2022 California Building Code, California Electrical Code, California Mechanical Code, California Plumbing Code, California Energy Code, California Fire Code, and California Green Building Standards Code, along with applicable NFPA standards for automatic sprinkler and fire alarm systems. The contractor is responsible for identifying and properly remediating any asbestos-containing materials encountered during demolition activities in accordance with federal, state, and local regulations. The design specifications include lead-free soldered fittings, PVC piping, copper materials, Tyler no-hub couplings, and water-efficient fixtures meeting EPA WaterSense standards with maximum flow rates of 0.5 GPM for public lavatory faucets and 1.28 gallons per flush for high-efficiency toilets. All piping offsets and fixture location changes necessary to conform to structural and architectural requirements must be made by the contractor without additional cost to the owner.
