Appendix_X_Hanover_Substation.docx

This is an equipment list appendix for the City of Palo Alto Utilities' Electric Substation Equipment Painting project, specifically detailing the inventory of equipment located at the Hanover Substation. The Hanover Substation contains six items requiring surface preparation and protective coating services: a 23 KV transformer manufactured by Hulman (159"W x 161"D x 161"H), a 22/23 switchgear unit by Allis Chalmers (400"W x 180"W x 120"H), a capacitor house structure by Butler (480"W x 144"D x 120"H), a trificator unit by Ohio Brass (48"H x 12" round with previously painted surfaces), and two padmount switches manufactured by Elliott. The Hanover Substation represents one of seven substations included in the broader citywide painting initiative. Work is anticipated to commence July 1, 2026, with a completion deadline of 1,095 working days from the Notice to Proceed. The 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.

The Year 1 engineering estimate for the Hanover Substation painting work is $58,000, representing approximately 6.2 percent of the total Year 1 project cost of $940,500 across all seven substations (which includes $100,000 in mobilization costs). All coating materials must meet utility-grade performance standards including ANSI No. 70 light gray finish paint and Fire Engine Red bushing caps using silicone alkyd. Contractors must hold current California state contractor licensure, comply with prevailing wage requirements under Labor Code Sections 1720 et seq., and maintain registration with the California Department of Industrial Relations. The City reserves the right to award the contract to a single contractor or multiple contractors, with bid security requirements of a 10 percent bid bond for bids exceeding $25,000, and selected contractors must provide performance and payment surety bonds each at 100 percent of the contract sum. Liquidated damages are assessed at $500 per day for failure to achieve final completion within the contract timeframe, and the City will retain 10 percent of undisputed amounts on each progress payment.
