Project Overview

Designed and coordinated the electrical systems for a new 911 call center in Grants Pass, OR, transforming an existing building into a mission-critical emergency response facility. The project required standby power, UPS systems, heavy-duty power distribution, and data infrastructure to ensure 24/7 operational reliability. Given the facility’s role in emergency response, every system was designed with redundancy, resiliency, and fail-safe operation in mind.

Role & Responsibilities

Legally Required Standby Power – Designed a generator-backed power system to maintain uninterrupted operations during outages, ensuring compliance with NFPA 110 and NEC emergency power requirements.

Uninterruptible Power Supply (UPS) – Engineered a double-conversion UPS system with sufficient battery backup to support critical operations during power transitions.

Redundant Power Distribution – Developed a dual-feed panelboard system with independent A/B power circuits for critical IT, communication, and dispatch equipment, reducing single points of failure.

IT & Communications Infrastructure – Integrated dedicated IT electrical panels, roof-mounted antenna power, and shielded power distribution to prevent electromagnetic interference (EMI) affecting dispatch operations.

Lighting & Controls – Designed low-glare, indirect lighting with dimmable controls to reduce operator fatigue in a 24/7 work environment.

Fire Alarm & Life Safety – Ensured fire alarm and security systems were powered by the standby generator, providing continuous monitoring and access control during emergencies.

Key Challenges & Solutions

🔹 Ensuring 24/7 Uptime with Redundant Power Systems – The facility could not afford power interruptions, requiring a layered backup strategy.
✔ Solution: Designed a standby generator and UPS system with a load prioritization strategy, ensuring uninterrupted operations.

🔹 Limited Space for Electrical Equipment – The renovation required fitting extensive power, UPS, and IT infrastructure into an existing building footprint.
✔ Solution: Used strategically placed distribution panels, transformers, and IT racks, optimizing space while maintaining accessibility for maintenance.

🔹 Data & Communications System Protection – Preventing power surges and EMI was critical for sensitive dispatch equipment.
✔ Solution: Installed isolation transformers, transient voltage surge suppressors (TVSS), and shielded grounding to protect communication systems from electrical disturbances.

Outcome & Impact

✅ Mission-Critical Resilience – The facility was designed with redundant power and data systems, ensuring uninterrupted emergency operations.

✅ Optimized Operator Work Environment – Implemented ergonomic lighting and workspace power solutions to enhance dispatcher comfort and efficiency.

✅ Reliable Power Infrastructure – The electrical system met stringent reliability requirements, providing seamless power transitions and future-ready IT integration.
