As_Built_Oak_Knoll.pdf

These are architectural and engineering design drawings for the Oak Knoll Substation, prepared by the Municipal Light and Power Department of the City of Pasadena, California. The comprehensive set of technical drawings includes detailed plot plans, conduit layouts, electrical and ground system schematics, and structural design specifications across multiple sheets (pages C-1 through E-2). The drawings provide intricate technical details for the substation's infrastructure, including transformer locations, electrical routing, foundation plans, cross-sections, and elevation views. The documents are dated 8-2-1988 and appear to be part of the as-built documentation for the Oak Knoll Substation project.

The drawings specifically relate to the oil containment system project described in the contract opportunity, which aims to bring the substation into compliance with EPA regulations under Title 40 CFR Part 112 for preventing environmental contamination from potential oil spills. The technical drawings demonstrate the detailed engineering approach to implementing oil containment measures, including specialized concrete structures, trenches, and routing systems designed to capture and control potential transformer oil leaks. The level of detail suggests a comprehensive approach to meeting federal environmental protection standards, with precise measurements, material specifications, and structural considerations carefully documented across multiple technical diagrams.
