Appendix_VIII_Quarry_Substation.docx

This is an equipment specification appendix for the City of Palo Alto Utilities (CPAU) Electric Substation Equipment Painting project, detailing the equipment inventory at the Quarry Substation that will require surface preparation and painting services. The appendix identifies ten major pieces of equipment requiring coating work, including two transformer units (XF QR 20 and XF QR 21) manufactured by National Industri with dimensions of 207"w x 146"d x 164"h, two additional transformers (XF QR 22 and XF QR 23) manufactured by KHULMAN measuring 159"w x 161"d x 161"h, two switchgear units (20/21 and 22/23) manufactured by Peterson at 356"w x 195"w x 119"h each, two ground circuit breakers (GCB 52QR 20 and 21) from Siemens SP 72, one oil circuit breaker (OCB 52QR) manufactured by Westinghouse model 690-G-3500, and one capacitor house manufactured by Butler with dimensions of 15'd x 45'w x 12'h. The appendix serves as a reference document for contractors bidding on the painting services contract across CPAU's seven electric substations.

The specification document provides detailed equipment dimensions and manufacturer information necessary for contractors to assess surface preparation requirements, coating material quantities, and project scheduling across the substation sites. This inventory documentation enables bidders to accurately estimate labor and material costs for the high-performance protective coating application required on transformers, breakers, steel structures, and associated components within the energized utility environment. The document includes photographic references of the equipment to facilitate contractor site familiarization and technical assessment prior to bid submission.
