Administrative Facilities Demolition

Orange County Sanitation District (OC SAN) is requesting bids for the complete demolition of Administration and Human Resources Buildings at Plant No. 1 in Fountain Valley, California, with bids due September 29, 2026, and a non-mandatory pre-bid conference and job walk on August 26, 2026. The project carries a California prevailing wage requirement and mandatory Class A California Contractor's License.

Scope includes demolition of existing structures, rerouting fiber-optic communications and network systems to the Plant No. 1 Control Center, decommissioning a Southern California Edison transformer, removing hazardous waste materials, cutting and capping utilities, site grading, installing lighting, and paving. The location is 10844 Ellis Avenue, Fountain Valley, CA 92708.

Bidders must demonstrate a minimum safety profile: submission of Cal OSHA 300/300A logs and safety declarations, with accident frequency factors and workers' compensation experience modification rates not exceeding 1.25 (higher rates render bids non-responsive). Bidders must also demonstrate completion of at least three non-residential demolition projects within the last five years, each involving a minimum 10,000 square feet of demolition and similar scope and complexity. All work must comply with California Air Resources Board mobile source emissions standards and certifications.

The engineer's estimate is $11.38 million. Contract completion is required within 550 calendar days from the effective date of the Notice to Proceed, with extensions permitted under specifications. Bid security of not less than 10 percent of the total bid amount (cash, certified check, or surety bond) is required at submission. Upon award, successful bidders must provide performance and payment bonds each at 100 percent of contract value within 15 calendar days of the Notice of Award. Contract award is anticipated within 120 days of bid receipt.

Written questions are due by 5:00 p.m. Pacific Time on September 15, 2026. Bids must be submitted electronically through OC SAN's Vendor Portal in OpenGov by 11:00 a.m. Pacific Time on September 29, 2026.
