Description

Caltrans is seeking a qualified small‑business contractor to fully replace the roof and HVAC systems at its Chico Maintenance Station in Butte County, while also handling hazardous‑material abatement (asbestos and lead) and related waste disposal. The work includes removal of existing roofing, installation of a new membrane roofing system, replacement of two HVAC units, management of solar‑panel removal/re‑installation, and compliance with extensive licensing, permitting, and environmental regulations. Bidders must hold multiple CSLB classifications (Class B, HAZ, C‑20, C‑22, C‑39) and possess certifications for asbestos and lead remediation, hazardous‑waste transport, and prevailing‑wage compliance. • Replace roofing membrane and timber decking, dispose of old materials per hazardous‑waste rules. • Remove, dispose of, and install two new HVAC systems meeting Title 24 energy standards. • Conduct asbestos and lead‑based paint abatement, submit approved abatement plans, and manage all related waste. • Provide all required permits, licenses, insurance, bonds, and a one‑year warranty on workmanship. • Submit monthly invoices with certified payroll; adhere to prevailing‑wage and safety regulations throughout the 19‑month contract.

Budget estimate

$400,000 – $461,000

The solicitation caps the contract at $461,000. Considering the extensive scope (roof replacement, two HVAC units, asbestos/lead abatement, waste disposal, permitting, and a one‑year warranty), the expected award will likely fall near the upper end of the range, roughly $400‑$460 k. Factors influencing the final amount include the selected HVAC equipment, unforeseen hazardous‑material quantities, and the bidder’s labor rates.
