July 28, 1998 Existing Capacity: Installed capacity is approximately 2250 Amps. Required capacity will be approximately 3900Amps. Service Entrance Feeders: Three service entrance locations are utilized and appear to be in good condition. Electrical Distribution: The main switchboards and distribution system appear adequate with no local shortage of power require- ments currently recognized. The original switchboards and asso- ciated electrical equipment are estimated to be approximately 20 years old. The history of proper maintenance for this equipment is unknown, and could create future problems. There appear to be code violations on working clearances and conduit routing. Communication system distribution: The existing system is installed to serve several users and requires full replacement to meet the new user need. Main distribution panelboard: The system consists of panels located in as many areas as tenant spaces exist. The system requires extensive re -work to accommodate the new office space usage. The existing service entrances could be used with one meter at each transformer allowing power distribution to different areas. Each electrical room multi -service layout will have to be replaced with 400 amp panel boards to feed the assigned area. Primary load analysis has revealed that the 400amp local services are not adequate and the existing aluminum feeders (4-750 KCM) require replacement to copper to increase the service capacity by 23% to 480amp. If the existing underground service entrances are used, significant savings are achieved. However, the required emergency genera- tor must be located inside the building and the emergency power distribution placed overhead to avoid costly underground work. Some of the local tenant panels and related step down transform- ers could be used where they are; however, several of them will require removal or relocation to new assigned electrical rooms. Fire alarm system: Upgrading and re -certification of the system is required. Exlt/Egress lighting: Upgrade to meet new layout is required. Security System: Upgrade to meet new layout is required. Raceway system: New raceway system to provide flexibility is recommended. Energy code compliance: The building does not utilize any known energy saving control systems. Emergency generator: The building does not utilize an emer- gency generator. UPS back-ups: Recommended. Lightning protection system: The building does have a system that covers 20% of the area. The remaining 80% of the building should have a system installed. 39 BOOK 106 Ftu 412
