DT-SS-U-1028_Pre-cast_Concrete_Pad_for_LBC_Cabinet.pdf

This document is an engineering standard drawing set from the City of Palo Alto, California's Utilities Electric Engineering department, detailing pre-cast concrete pad specifications for LBC (likely Local Boundary Cabinets) installations. The three-page technical drawing set (DT-SS-C-1028) provides precise dimensional and construction details for three different concrete pad configurations, each with specific requirements for placement, reinforcement, and associated vault or box installations.

The drawings specify detailed technical specifications including #4 rebar placement, concrete base requirements, pad dimensions, and installation notes. Each pad variant (A, B, and C) has unique measurements and is designed to accommodate different equipment configurations, such as a 30" access frame and cover (Alhambra A1252) in the third sheet. The notes consistently emphasize centering pad windows over boxes, using 6" compacted sand under installations, and following specific City of Palo Alto standard drawing requirements for vault and pad construction. The drawings were approved in 7/1984 and have undergone minor revisions, with the most recent revision on 1/12 adding box details.
