Summary

This is a comprehensive drawing index and set of design drawings for the Navajo-Gallup Water Supply Project's San Juan Lateral turnout buildings and associated infrastructure. The document serves as the master drawing index (1695-D-62526) for the Bureau of Reclamation project, cataloging 131 detailed construction drawings organized by discipline (civil, mechanical, electrical, piping, and structural).

The project encompasses six turnout buildings (Sanostee, Newcomb, Naschitti, BBN9, Coyote Canyon, Rock Springs, and Window Rock) along with access roads, yard piping systems, and line pipe installations across multiple reaches (Reaches 4C through 12.2). Key deliverables include site plans, grading plans, piping and instrumentation diagrams (P&IDs), electrical site plans, structural details, pressure pipe trench installation specifications, sectionalizing valve installations, and cathodic protection system details. The drawings specify materials including steel and ductile iron pipe in various sizes and pressure classes (48B600, 42C350, etc.), CLSM (Controlled Low Strength Material) bedding requirements, and standard trench details for different soil material types. Construction documents reference New Mexico State Plane Coordinates (NAD83 datum), establish 80-foot right-of-way requirements, and include detailed profiles showing hydraulic grade line elevations, miter bends, wash crossings, and buried infrastructure. The project also incorporates fiber optic communication systems, control systems, and network infrastructure per the electrical specifications provided across multiple turnout building P&ID sheets.
