Primary Electrical Distribution System Repair, NASA Armstrong Flight Research Center, Edwards Air Force Base, CA
The purpose of this project was to repair the Armstrong Flight Research Center electrical distribution system by replacing high-voltage cables and equipment.
- Installing approximately 13,800 lineal feet of new concrete encased duct banks and 39 new electrical manholes.
- Three (3) existing electrical equipment concrete pads were expanded.
- Four (4) new electrical equipment pads were installed.
- Soil borings were taken at the new electrical manhole locations in order to accurately predict the amount of granite bedrock that was encountered during construction.
- Asphalt pavement repair was required to install new underground ductbanks.
The electrical scope included high-voltage cable replacement, new electrical equipment at substations, new high-voltage underground feed, and arc flash hazard analysis.
