Drawing_Rev_2_DT-SS-U-1028_Pre-cast_Concrete_Pad_for_LBC_Cabinet.pdf

This document is a set of engineering design standards for pre-cast concrete pads for LBC (Line Box Cabinet) from the City of Palo Alto, California's Utilities Electric Engineering department. The three-page technical drawing set (DT-SS-C-1028) provides detailed specifications for three different concrete pad configurations, each with specific dimensional requirements, rebar placement, and installation notes. Each pad is designed for a different utility installation, with variations in size, pad window placement, and accompanying vault or box requirements.

The drawings include specific technical details such as #4 rebar placement, concrete base thickness, sand compaction requirements, and precise measurements for pad dimensions. Notes on each drawing specify installation requirements, such as placing a 6" compacted sand base, centering pad windows over boxes, and installing precast vaults according to specific city standards. The documents are dated 7/19/94 and have revision notes indicating updates in 1/12 and 6/15, with the most recent revision adding box details. The drawings reference additional city standard drawings and specify requirements for different cabinet and vault installations, suggesting these are part of a standardized infrastructure development process for utility infrastructure in Palo Alto.
