Appendix_XI_Hansen_Way.docx

This is an equipment list appendix for the City of Palo Alto Utilities' Electric Substation Equipment Painting project, detailing the Hansen Way Substation inventory requiring coating services. The appendix identifies nine items of electrical equipment across the Hansen Way location, including four transformers (XF HW 20, 21, 22, and 23) manufactured by GE, Delta Star, and Khulman with 14 MVA ratings; two switchgear units (SWITCHGEAR 20/21 and 22/23) manufactured by Allis Chalmers and Peterson with specifications ranging from 255 to 328 inches in width; one circuit breaker (52 HW) manufactured by Westinghouse; and two trificators (HW-PBS and HW-HV) manufactured by Ohio Brass, each measuring 48 inches in height by 12 inches in diameter with notation that previously painted surfaces only require coating. The Hansen Way Substation represents one of seven substations across Palo Alto's distribution system included in the broader painting project, with an estimated Year 1 cost of $150,000 for surface preparation and protective coating services. A non-mandatory pre-bid meeting and site walk is scheduled for April 15, 2026, 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. Work is anticipated to commence July 1, 2026, with a completion deadline of 1,095 working days from the Notice to Proceed.

The Hansen Way equipment must receive utility-grade protective coatings meeting ANSI No. 70 light gray finish standards with Fire Engine Red bushing caps using silicone alkyd, compliant with Steel Structure Painting Council and OSHA standards, and backed by a minimum one-year warranty. The broader project budget allocates $940,500 for Year 1 across all seven substations plus mobilization costs, with subsequent annual expenditures ranging from $274,000 to $327,000 over a four-year project timeline. Selected contractors must hold California state contractor licensure, demonstrate full site inspection knowledge, and comply with California prevailing wage requirements under Labor Code Sections 1720 et seq. Bid security requirements include a bid bond of at least 10 percent of the aggregate bid amount for bids exceeding $25,000, with performance and payment surety bonds each required at 100 percent of the contract sum within 10 business days of Notice of Award. Liquidated damages are assessed at $500 per day for failure to achieve final completion within 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. The City reserves the right to award the contract to a single or multiple contractors.
