ABSTRACTThis is the fifth revision of the Minimum Check List since
its origin in 1960 by North Carolina's School Planning. The checklist wasdeveloped to serve as a means of communication between school agencies anddesign professionals and has been widely used in the development and reviewof mechanical and electrical plans and specifications by engineers,architects, and superintendents in planning public school facilities. Thechecklist has three primary sections: plumbing systems, mechanical systems,and electrical and lighting systems. Specific guidelines on drainage andwaste, fittings, fixtures, water supply, gas systems, stack and breeching,boilers, oil burners, piping, heaters, controls, heating systems, airconditioning, service entrance feeders, branch circuits, and alarm systemsare provided. Diagrams showing grounding methods, a typical electricalsummary, and recommended lighting systems with illumination levels appear atthe end. (RJM)

SUBJECT: "Minimum Check List for Mechanical and ElectricalPlans and Specifications"
BOB ETHERIDGEState Superintendent
June 29, 1992
Numerous changes have been made in the mechanical and electrical fields sincethe previous publication of the "Minimum Check List". The revision attached is
an effort to address those changes. The following focus on several which
require special attention.
PLUMBING PLANS AND SPECIFICATIONS
1. The major domestic hot water deman0 in public schools is the kitchenequipment. Generally, this is a 140"F requirement. Such heaters shouldsupply kitchen equipment only and should be fossil-fuel fired.
2. With the exception of kitchen and athletic facilities, all other hotwater may be electrically heated as the demand is not that great.Separate generation equipment should be provided for low temperaturerequirements (lavatories and showers) to eliminate all chances of
scalding.
3. Always recirculate from the most distant fixture or fixture group.However, the smallest recirculation pump available will usually sufficefor any application.
4. Plumbing fixture trim should be completely specified as well as
fixtures. Generally, drafting schedules are incomplete. What is notspecified usually gets installed at lower quality.
5. Place isolation valves as if you had to pay for them and service thefixtures in the future.
6. Do not use aquastats or mixing valves. Instruct draftsmen to deletethem from "standard" details.

HVA/C PLANS AND SPECIFICATIONS
1. Provide access to all HVA/C equipment as if you were to be servicing it.
2. Hydronic systems installed now will give system fuel and equipmentflexibility in tile future.
ELECTRICAL PLANS AND SPECIFICATIONS
1. Short Circuit (Fault) Currents and Withstand Ratings
As a result of the increase in capacity of the National Electrical PowerSystem grid, and larger and air conditioned schools requiring moreelectric power capacity, the snort circuit currents available at theservice entrance conductors and panels are gradually getting larger.The available short circuit current (or KVA) should be placedon theriser diagrath so an awareness is made to electrical engineers, that willremind them to provide proper coordination of the electrical systemwithin the school buildings for both new and reT0deled projects, withemphasis on older buildings.
2. Non-linear Loads
Numerous computers, ballasts (electromagnetic and electronic) forlighting fixtures, adjustable frequency motor drives and otherelectronic equipment will be installed in new and existing schools.The non-linear loads and harmonics are of considerable concern in theseinstallations. Transformers designed for non-linear loads and oversizedneutrals for feeders and branch circuits should be considered in theseapplications.
3. Transient and Surge Voltages
Electronic equipment is very sensitive, and protection is generallynecessary for lightning, power company switching and generation surgesand disturbances created within the school building electrical system.Transient and surge protection can be provided at:
a. The service entrance.
b. In the panelboards serving the electronic equipment.
c. In the receptacles serving the electronic equipment (if the equipmentdoes not have built-in protection).
One, a combination of the three or all three may be needed. Use yourprofessional knowledge and judgement. Protection is required for tele-phone and data conductors which go from building to building or acrosstown.
Page 3June 29, 1992
4. Lighting Systems
Recommended lighting levels are now indicated with a minimum and maximumfoot candle range. The type of lighting fixtures which are acceptableare included for each particular area. Incandescents and mercury vaporare "out" except where noted. The use of electronic switches areencouraged to disconnect lighting circuits in unoccupied rooms.
5. Americans with Disabilities Act (ADA)
Particular attention is directed to sound systems, fire alarm systems,exit and emergency lighting and telephone accessibility. Correctivemeasures to assist the sight and hearing impaired are addressed in theADA. Hearing aids connected to telephones and auditorium/gymnasium/multi-purpose room sound systems, additional flashing strobe lights forrestrooms, strategic placement of all the audible/visual devices in firealarm systems and sufficient lighting for emergency situations andproper directions for exits shall be provided.
