Appendix_V_Colorado_Substation.docx

This is an equipment list appendix for an Invitation for Bids (IFB) issued by the City of Palo Alto Utilities (CPAU) for surface preparation and protective coating services across seven electric substations. The Colorado Substation Equipment List details 29 items requiring painting services, including transformers (XF CO 20, XF CO 21, XF CO 1, and XF CO 3), circuit breakers (OCB and GCB models from manufacturers including ITE, Siemens, and ABB), switchgear, control cabinets, capacitor houses, oil pumphouses, and steel support structures such as dead-end structures and poles. The project scope encompasses cleaning, surface preparation, corrosion treatment, priming, and application of high-performance utility-grade protective coatings suitable for energized utility environments. A non-mandatory pre-bid meeting and site walk is scheduled for April 15, 2026, at 9:00 a.m. at the Colorado Substation; written questions must be submitted by April 17, 2026, at 1:00 p.m.; and electronic bids are due April 24, 2026, at 3:00 p.m. through the City's OpenGov procurement portal. Work is anticipated to commence July 1, 2026, with a completion deadline of 1,095 working days from the Notice to Proceed.

The Year 1 engineering estimate for the Colorado Substation painting costs is $209,500, with a combined Year 1 total across all seven substations of approximately $940,500 (including $100,000 in mobilization costs). Subsequent annual expenditures are projected to range from $274,000 to $327,000 over a four-year project timeline. All materials and coating systems must meet or exceed utility-grade performance standards, including ANSI No. 70 light gray finish paint and Fire Engine Red bushing caps using silicone alkyd, with compliance required to Steel Structure Painting Council (SSPC) and Occupational Safety and Health Administration (OSHA) standards and a minimum one-year warranty. Contractors must hold California state contractor licensure, demonstrate evidence of full site inspection and project knowledge, and maintain registration with the California Department of Industrial Relations (DIR). All selected contractors must comply with California prevailing wage requirements under Labor Code Sections 1720 et seq. No specific set-asides for disadvantaged enterprises are detailed, and no incumbent vendors or current contractors are identified. Bid security requirements include a bid bond of no less than 10 percent of the aggregate bid amount for bids exceeding $25,000, with performance and payment surety bonds each required in the amount of 100 percent of the contract sum within 10 business days of the Notice of Award. Liquidated damages are assessed at $500 per day for failure to achieve final completion within the contract time, and the City will retain 10 percent of undisputed amounts on each progress payment, with payment due within thirty days of receipt of properly submitted applications.
