Appendix_VII_Maybell.docx

Appendix VII is a supporting document for the City of Palo Alto Utilities' Electric Substation Equipment Painting project, detailing equipment specifications for the Maybell Substation. The appendix identifies three major pieces of equipment requiring surface preparation and painting services: two 28 MVA transformers manufactured by McGraw Edison (each measuring 172"w x 172"d x 204"h) designated as XF MB 20, and one switchgear unit (20/21) manufactured by BBC (measuring 363"w x 200"d x 120"h). The document includes photographic images of each equipment item to provide visual reference for bidders. These specifications serve to inform contractors of the specific transformers, breakers, and associated components they will be responsible for cleaning, surface preparation, corrosion treatment, priming, and applying high-performance protective coatings on as part of the broader seven-substation painting initiative.

The document provides essential technical details necessary for contractors to assess project scope, material requirements, and work planning for the Maybell Substation portion of the contract. By identifying equipment manufacturer, model designation, and physical dimensions, the appendix enables bidders to accurately estimate labor, material quantities, and coating coverage requirements specific to this location. This level of specification ensures that selected contractors understand the scope of equipment involved and can develop appropriate methodologies for working safely on utility-grade infrastructure while maintaining service reliability.
