HDPE water main, install backflow device, and upgrade exterior hose system. • Reroute and replace interior water lines, connect to all fixtures, and maintain continuous restroom access (max 4‑hour outage). • Conduct asbestos and lead‑based paint surveys, develop abatement plans, and perform removal/encapsulation in compliance with CSLB, DIR, CDPH, and EPA regulations. • Provide all required permits, licenses (Class B, HAZ, C‑22, C‑36), hazardous‑waste transport registrations, and prevailing‑wage certifications. • Must be a certified Small Business, Micro Business, SB‑PW, or DVBE and meet all DIR and labor‑law requirements.

Budget estimate

$300,000 – $461,000

The solicitation caps the contract at $461,000. Considering the extensive plumbing replacement, backflow device installation, and required asbestos/lead abatement, a realistic award will likely fall between $300,000 and the $461,000 ceiling. The lower bound reflects a minimal scope (only plumbing) while the upper bound includes full hazardous‑material remediation, travel, disposal fees, and all required certifications.
