About this file
This document is a comprehensive set of electrical one-line diagrams for a major healthcare facility construction project in Aurora, Colorado, dated April 29, 2024. The diagrams depict the normal power system, essential electrical system, and medium voltage distribution infrastructure across thirteen buildings plus an energy center.
The project encompasses extensive electrical system designs including unit substations ranging from 1,000 to 4,000 KVA capacity at 13.2 KV primary voltage stepping down to 480/277V and 208/120V secondary voltages. Key facilities include research buildings, diagnostic and treatment centers, inpatient bed buildings, clinic facilities, parking structures, and a centralized energy center with multiple generator backup systems (2.0 MW units at 13.2 KV). The designs incorporate automatic transfer switches (ATS) with bypass-isolation capabilities for critical loads, surge protective devices (SPD) rated at 240,000A protection per mode, and K-rated transformers with dedicated neutral conductors. Feeder schedules specify aluminum and copper conductors (ranging from #10 AWG to 500 KCMIL) sized for voltage drop compliance, with detailed transformer schedules providing dimensions, weights, and BTUH output ratings. The infrastructure supports life safety systems, critical equipment loads, and normal operations with segregated distribution panels serving lighting, HVAC, medical equipment, and general purpose loads across multiple building levels. Special provisions include photovoltaic system integration with circuit breaker sizing per NEC 705.12(D) standards and grounding electrode systems utilizing ground rods with concealed grounding electrode conductors.
