(7) Description (including Riser Diagrams) of Cable Television Systems
(CATV), Closed Circuit Television Systems (CCTV), nurse call, intercom, sound, signal,
and fire alarm systems.
(8) Statement relative to supporting facilities (outlets, raceways, and
backboard) to be provided for telecommunication systems. Number and location of
telecommunication outlets (i.e., telephone, computer, word processing, etc.) should be
obtained from the using activity. Identify space required for telecommunication
equipment, point of connection to base telephone system, size of incoming
duct/conduit, and size of equipment mounting backboard; this information should be
obtained from the Activity Providing Telephone Service (APTS) officer. Statement
relative to interface provision for multi-use systems (i.e., intercom, telephone, etc.).
A&E must provide all facility support for proposed telephone equipment installations,
i.e., conduit, duct, and backboard. Design and procurement of telephone system to be
accomplished by the Activity Providing Telephone Service (APTS) officer.
(9) Provide lighting calculations keyed to lighting floor plan and lighting
fixture schedule.

(2) Statement relative to the adequacy of the primary power source at the
point of pick-up. If primary source is inadequate, state measures proposed to correct
the deficiency.
(3) Electrical characteristics of power source, including circuit
interrupting requirements and voltage regulation.
(4) Estimate of total connected load and resulting kilowatt demand load
by applying proper demand and diversity factors, if a group of loads is involved.
(5) Basis for selection of primary and/or secondary distribution voltage.
(6) Type of conductor material, such as copper or aluminum, and where
proposed to use. Type of insulation for cable systems.
