Attachment J-1601000-04 (a)- NRL Utility Drawings - Elec and Comm.pdf

This document is a set of utility drawings for the Naval Research Laboratory (NRL) in Washington, D.C., depicting electric and communication systems infrastructure across the facility's campus.

The drawings provide comprehensive site plans showing the distribution of electrical lines, communication systems, utility conduits, and related infrastructure organized by geographic grid sections (designated A through J and rows 1 through 13). Key utility elements depicted include compressed air lines, concrete conduits, chilled water return and supply lines, electric power distribution, gas lines, nitrogen systems, sanitary and storm drain systems, steam lines, telephone risers, water valves, and various support structures such as lamp posts and sign poles. The drawings identify specific buildings, utility access points, electrical equipment locations, transformers, cable routes, and connection points. Horizontal and vertical control references (NRL GPS 1 and NRL GPS 2) are provided with specific coordinate and elevation data to establish surveying baselines. The document includes a comprehensive legend defining all utility line types and symbols used throughout the drawings. Dated October 30, 2015, and marked "Information Only—Not for Construction," these drawings were prepared by Summer Consultants Incorporated for the Naval Facilities Engineering Command and serve as reference documentation for the existing utility infrastructure at the Naval Research Laboratory facility.
