S02 - ATT 15 - 581-22-700 - 100 Drawings Part-13 of 24.pdf

This file contains electrical design drawings and one-line diagrams for the EHRM Infrastructure Upgrades project at the Huntington VA Medical Center. The drawings depict detailed electrical details, telecommunications enclosure elevations, power schematics, and one-line diagrams for Buildings 01, 01S, 01W, 02, and 03, showing existing and revised electrical configurations. Key electrical components specified include rack-mounted UPS units (Eaton 93PX5K or equivalent, 5 kW, 208V), rack PDUs with L21-20 connectors (Chatsworth or APC equivalents), transformers ranging from 9 kVA to 225 kVA with various voltage configurations, automatic transfer switches (ATS) rated from 100A to 600A at 480V/277V, panelboards, bus ducts with spring hangers, and extensive power distribution infrastructure. The drawings also specify telecommunications bonding requirements per ANSI/TIA-607-E standards, including primary and secondary bonding busbars, telecommunications bonding backbones, and detailed grounding and bonding conductor specifications.

The drawings show complex three-phase power distribution systems with detailed schematics for data center power elevation, server cabinet rows with overhead busways (100A and 250A configurations), cable tap boxes with 200% neutral capacity, and integration with building BMS systems via CAT-6A Ethernet connections and SNMP v3.0/BACnet/Modbus protocols. Fire alarm system integration is depicted with clean agent system panels, emergency shutdown capabilities via UPS deactivation and breaker shunt-trip mechanisms, and humidification/dehumidification equipment controls. The documents indicate 100% Construction Documents phase dated 09/03/2025, prepared by SPEES Design Build for the Office of Construction and Facilities Management, Department of Veterans Affairs, with project address at 1540 Spring Valley Drive, Huntington, WV 25704.
