Study for the replacement of the existing 15kV, dual line 10MVA primary service switchgear which served the main campus. The study included various options for sighting the service entrance switchgear and the reconfiguration, modification, and extension of the facility's existing underground duct bank system to minimize the duration for shutdowns and single line exposure to the hospital throughout the construction process. The study also included phased planning for the retirement of the facility's original underground 5KV distribution system, transformers and associated distribution equipment, as well as a complete upgrade of the facility's 15kV primary feeders.
