Electrical Distribution Replacement and Upgrade – Audie L. Murphy VA Hospital

San Antonio TX

LAN analyzed and implemented the full replacement of the main electrical system serving the VA hospital. LAN’s team developed a detailed electrical analysis of all existing systems and designed a new medium voltage system (35kV) to meet current and future needs. The hospital, comprising multiple essential facilities, required operations and security to be maintained 24/7 during the entire project. The hospital’s facilities include an acute care unit, nursing home, spinal cord injury center, biomedical research facility, hospital, and surgical center.

The project included the following elements:

• Replacement of an aging electrical switchgear(15 kV and 480 V) and transformers (4@ 2500 KVA each)
• New masonry vault structure to house new switchgear
• Development of an electrical model of the facilty’s electrical distribution system
• Ventilation upgrade for the existing transformer room
• Transition of loads from existing switchgear to new switchgear
• Development of bid documents to keep hospital operational during construction
