5. ELECTRICAL
a. Submit a narrative describing the design, including basic assumptions and
points of interconnection with the existing electrical systems. Provide a statement of
the impact of the new construction to the existing electrical distribution system.
Include current demand loading (high voltage switchgear and primary feeder) and
projected load of new construction. Propose various feasible electrical systems for
the project and provide advantages/disadvantages. Include life cycle cost analyses
for the major electrical distribution system equipment.
b. Indicate room titles and area functions location and sizes of electrical equipment
rooms and electrical, telephone, and signal closets on drawings. Show all electrical
distribution equipment at scale. Include means and clearances for installation,
maintenance and removal/replacement of equipment.
c. Provide a sheet for symbols, lighting fixture schedules, notes and abbreviations.
d. Submit a plot plan showing existing and proposed electrical underground power,
telephone, and signal inter-building systems (F/A, CCTV, MATV, radio, security,
etc.) associated with the new construction.
e. Submit a clear, concise elementary one-line diagram of the proposed electrical
system. Include high voltage and low voltage switchgear, transformers and low
voltage main and/or distribution panels, branch panels and representative methods
of feeding 277/480 volt and 120/208 volt normal and emergency panels. Indicate
ratings and locations of existing electrical devices to be reused.
f. Submit a list of the specialty areas (Include X-Rays, Intensive Care Units and
Operating Room Suites) that will provided for DD1.
g. Describe the proposed method of short-circuit calculations. Describe the
method by which voltage drop and demand will be calculated.
h. Complete necessary life cycle costs analysis for major electrical systems.
Provide narrative report on the various designs with priority on recommended
designs. Weigh alternatives and convey convincingly the recommended alternative.
i. Provide copies of all correspondence and minutes of meetings with the utility
company's representatives.
j. Submit preliminary square foot load calculations for both normal and emergency
use. Separate calculations into lighting, receptacles, and power (kitchen, x-ray,
elevator, and mechanical).
