Provided Electrical Engineering services for replacing six existing automatic transfer switches serving various areas and wings of an existing hospital. Engineering Design services and construction administration services were provided for this project. A summary of our scope of work is described below:
- Studied the existing emergency distribution system in order and determined appropriate size, fault current settings and ampere interrupting capacity of new automatic transfer switches and related circuit breakers.
- Provided a new location for the six new automatic transfer switches and used the existing automatic transfer switch enclosures to splice new feeders to existing feeders.
- Investigated the space available in the existing electrical room for routing new feeders and provided drawings for relocating small portions of existing ductwork in order to provide a pathway for the proposed feeders.
- Specified bypass automatic transfer switches with draw out type switches for ease of routine maintenance and servicing of automatic transfer switches.
- Recommended testing of existing feeders between the existing generator and existing transformer serving the 2000 ampere emergency bus. Upon receiving the results, provided a new routing of feeders which were found to have water damage due to the existing routing.
- Sized and provided the routing for new conduit and feeders from the existing location to the new location of automatic transfer switches.
- During the construction phase, reviewed shop drawings for the automatic transfer switches and related electrical equipment and coordination study for the emergency distribution system.
