Colorado Substation Equipment List Summary

This is an equipment inventory appendix for the City of Palo Alto Utilities' electric substation painting project, detailing the Colorado Substation asset roster. The Colorado Substation contains 29 items requiring surface preparation and protective coating services, including two 15MVA transformers manufactured by RTE, one 160MVA transformer by Federal Pacific, two 160MVA transformers also by Federal Pacific, Peterson switchgear, McGraw capacitor house, FPE auxiliary distribution switchgear, MAC oil pumphouse, nine circuit breakers from manufacturers including ITE, Siemens, and ABB, two ABB control cabinets, and nine dead-end steel structures with varying column and beam configurations. Equipment dimensions range from control cabinets measuring 116" wide by 41" deep by 92" high to large transformers exceeding 238" in width and 235" in depth. The project involves comprehensive cleaning, corrosion treatment, priming, and application of utility-grade protective coatings meeting ANSI No. 70 light gray finish standards with Fire Engine Red bushing caps using silicone alkyd paint.

The Colorado Substation represents the most extensive equipment inventory among the seven substations in the Palo Alto distribution system, with Year 1 painting costs estimated at $209,500 plus a proportional allocation of the $100,000 mobilization budget. The contract timeline extends for approximately 1,095 working days from the Notice to Proceed, with work anticipated to commence July 1, 2026. Bid submissions were required by April 24, 2026, at 3:00 p.m., with a non-mandatory pre-bid meeting and site walk conducted at the Colorado Substation on April 15, 2026, at 9:00 a.m. Liquidated damages are assessed at $500 per day for failure to achieve final completion within the contract time, and selected contractors must comply with California prevailing wage requirements and provide performance and payment surety bonds each equal to 100 percent of the contract sum.
