East Campus Existing Building Conditions Electrical and Communications
Electrical Distribution System
The campus electrical distribution system is 7,200/12,470 volt, 3-phase underground service. Service entrance to campus terminates at switchgear in close proximity to the central plant building. The switchgear contains six switches. Four of six switches serve two loop feeders. The remaining two switches each serve radial feeders. Total quantity of transformers served by all feeders is sixteen.
The total system load at main feeder and several branch feeders is currently at or above normal capacity when compared with calculated connected loads. Some evidence indicates that calculated connected loads may not be archived in actual loading of the system. Sufficient records do not exist to determine historical loading of each branch of the existing distribution system. Future construction will be dependent upon the existence of spare capacity within the existing distribution system, or potential of such capacity if not existing.
Communication Distribution Systems
The active campus communication distribution system is comprised of underground 2" and 4" PVC conduit which currently contains both copper and fiber optic cabling for distribution of voice, data, energy management, and CCTV systems. The Administration Building currently serves as the main distribution point for voice (telephone) and data transmission. The Venters Business Building currently serves as the secondary distribution point for data transmission. The Science Building and Harvin Center currently serve as secondary distribution points for voice (telephone) transmission. The recently installed telephone switching equipment at the Harvin Center is connected to serving equipment at the Administration Building via multi-mode fiber optic cable.
Recently installed multi-cell conduit, which is routed parallel with chilled water piping in loop fashion around the campus, is planned to be utilized for expansion of communication systems. Multi-cell conduit is currently terminated at in-grade pull boxes which are typically located in close proximity to the various buildings. Multi-cell conduit extensions must be installed from such pull boxes to distribution point within each building prior to communication system expansions. Subsequent to installation of such extensions, systems cabling will be installed in multi-cell conduit as required to accomplish the desired system expansions. The 2" and 4" conduit systems will remain in use for distribution of voice (telephone) cabling.
