3-4 BUILDING DESIGN (cont'd)
(7) Electrical Design. Electrical design must conform to DoD 4270.1-M and TMs 5-811-1 through 4.
The system selected will provide efficient and economical electrical service throughout the ACES
Center. Voltages selected will be of the highest order consistent with the load served. Three phase
208Y/120 volts should generally be used to serve incandescent and small fluorescent or mercury
vapor lighting loads, small power loads, and receptacles. Consideration should be given to the use of
three-phase 480Y/277 volt systems where such is feasible. Distribution of power within the building
should be located to afford maximum flexibility in room power supply and ready accessibility for
circuit revisions. Primary electric service will be underground to a pad mounted transformer(s) located
outside below grade where possible, and as close to the load centers as practicable. Building
telephone service will also be underground with main terminal cabinets located in mechanical or
electrical equipment rooms. Communication systems must be coordinated with the local
Communications/Electronics Officer. Evidence of such coordination will be provided in the project
design analysis document.
(8) Toilet Fixtures. Both female and male toilets shall be provided to allow for convenient use by
staff and students, including those who may be handicapped. Male-female ratio and fixture allocation
are specified in Chapter 4 under individual space criteria for toilets, paragraph 4-5.e. At least one water
closet and lavatory for each sex will be provided for the physically handicapped in accordance with the
distance of travel and other criteria contained in EM 1110-1-103. Provide at least one drinking fountain
per 100 persons. All computations should be based on the peak daily occupant load determined by
adding up the occupant loads of all of the instructional and staff space in the ACES Center.
(9) Plumbing Design. Plumbing must be in accordance with TM 5-810-5 (and TM 5-810-6 if gas
fittings are required). Water supply facilities must be as prescribed in TM 5-813-3 and 6. Sanitary
sewers must be as prescribed in TM 5-814-1. Plumbing and fixtures shall comply with the "American
National Plumbing Code A 40.8" or the "National Standard Plumbing Code," within the limits
established by DoD 4270.1-M.
(10) Life Safety. Design provisions shall be made to assure health and safety as set forth in
Occupational Safety and Health Act (OSHA) standards and National Fire Protection Association
(NFPA) Codes augmented by DOD and Army criteria. Fire protection is a significant part of building
design and involves the provision of resistive construction, detection and alarm systems, and
extinguishment systems.
(a) Resistive Construction. Requirements for fire-rated walls, doors, floors, etc., depend upon the
type of occupancy or hazards within a space. The objective is to contain and retard fires to allow
evacuation, rescue and extinguishment. Resistive construction is especially important around pas-
sageways used for emergency exit.
(b) Detection and Alarm. Alarm systems are used as a general alert of danger whenever a fire
occurs and is detected. Alarms can be supplemented by either heat or smoke detectors that sound an
