4. ALL IDG LAND USE ZONES

a. General Guidelines

i. Voltage Systems: Project designs shall incorporate standard voltage systems.

The standard voltage systems shall be one of following: 480 Volt delta 3 phase 3 wire, 480/277 Volt wye 3 phase 4 wire, 208/120 wye 3 phase 4 wire, and 240/120 1 phase 3 wire. A ground conductor shall be extended for every circuit.

ii. Wire: Use only copper conductors except as specifically permitted by the Government. Use THHN or THWN insulated copper conductors for branch circuit and feeder applications. Use twisted shielded wire or other special conductors as recommended by the equipment manufacturer or as specified by the Government.

Type NM cable will not be used except for residential construction or where specifically permitted by the Government. Type NM cabling will also not be allowed in mechanical spaces, office areas or industrial areas. Type MC or AC cable shall only be used for lengths of 6 feet or less as permitted by Code for final connections to equipment subject to movement or vibration. For 120 volt 20 amp lighting and receptacle circuits with receptacles located over 100 circuit feet from the receptacle panel, utilize minimum 10 gauge wire, except that 12 gauge pigtails, properly spliced, may be used for the last 6 feet for connection to the receptacle. Do not allow shared neutrals for branch circuit wiring. Run (a ) separate hot(s) neutral, and ground to the panel board for every branch circuit. For lighting fixtures recessed in suspended ceilings, utilize short lengths (6 feet or less) of flexible metallic conduit, or 6 feet or less of type AC or MC cable for final connections. All feeders shall also be run with separate hot(s), neutral, and ground.

5 | P a g e

iii. Conduit: Unless noted otherwise, utilize EMT conduit in dry areas indoors where allowed by Code. Utilize compression type connectors. Short lengths (6 feet maximum) of flexible metal conduit may be used for connection to light fixtures or equipment subject to vibration or movement where allowed by Code. Longer sections of flexible metal conduit or liquid tight flexible metal conduit may be used for fishing down hollow walls or other inaccessible spaces where allowed by Code. Utilize rigid galvanized steel conduit outdoors above grade. Provide an insulated bushing for box or equipment connections for all types of conduit.

iv. Conduit installation: Arrange conduit to maintain maximum headroom. Unless specifically permitted by the Government, do not create any new low spots, especially in hallways. When running above suspended ceilings, run conduit as high above suspended ceiling as possible. Conceal in new walls and partitions and above suspended ceilings. Conceal conduit to the maximum extent possible.

Conduit may be exposed in unfinished areas such as open basement areas.

However, do not create new low spots, especially in areas such as corridors.

Maintain 12 inch clearance between conduits and heat sources such as steam pipes. Conduits shall not block access to repairing valves or other mechanical or architectural features. Conduits shall not be supported from other conduit or piping or ductwork. In suspended ceiling construction, raceways shall not be fastened to the ceiling supports or to the suspended ceiling. When penetrating walls or floors, core drill holes of a size no larger than required. Locate floor penetrations close to walls to cause the least interference with usage of the space.

Floor penetrations shall be located in mechanical or electrical rooms wherever feasible. Provide firestopping for floors and fire rated walls, and seal holes in non-fire rated walls. Unless noted otherwise, conduit installed outdoors and conduit exposed to view in finished spaces indoors such as offices shall be painted to match the adjacent surfaces.

v. The minimum box size shall be 4 inches by 4 inches, except that 2 inches by 4 inches shall be permitted for boxes that contain the final device and do not feed through to other devices. Boxes shall be a minimum of 1-1/2 inches deep. Plastic boxes are not allowed except where specifically allowed by the Government.

vi. All nuts, bolts, washers, and other hardware installed outdoors shall be galvanized or stainless steel.

vii. Provide engraved plastic nameplates with 3/16 inch high letters to identify all disconnect switches, starters, panelboards, circuit breakers(other than in lighting panelboards and load centers), and other major pieces of equipment by name and function, operating voltage, and maximum fuse size (if applicable). Submit nameplate wording to Government for approval. Labeling switches, for example, as S-A, S-B, which are convenient labels used by a project designer for a specific project but which obviously do not follow any installation-wide naming convention, does not satisfy this requirement, since every job could potentially have switches with this name. The wording should use the naming conventions established or agreed to by the Government. Use screws to attach nameplates.

6 | P a g e

viii. Disconnect Switches: Use heavy duty fused/non fused disconnect switches complete with visible switch blades.

ix. All motors shall be equipped with a disconnecting device (or plug if 120 volt plug and cord connected) capable of being locked out, located within 10 feet of the motor. Exception: if the motor is part of a piece of equipment that was manufactured with one lockable in the off position disconnecting device located at the equipment that controls all the motors on that piece of equipment, separate disconnecting devices are not required for each of the motors, unless specifically required by the Government or by Code.

x. Receptacles: Use specification grade, 20 ampere 120 volt, 3 wire grounding type, duplex, NEMA configuration 5-20R for all convenience outlets.

b. Fire Alarm System

i. Regulations: The designer shall ensure that the Fire Alarm System design complies in all respects to the most current editions of the UFC Criteria and the Fire Codes, especially NFPA 72, 90A, and 101, except as modified by UFC 1- 200-01, “Design: General Building Requirements”. Also pay special attention to UFC 3-600-01, “Fire Protection Engineering for Facilities”. The system must also comply with the latest edition of the Americans with Disabilities Act and Architectural Barriers Act Accessibility Guidelines.

ii. Wire and Cable: Use wire types and gauges as recommended by the equipment manufacturer. Copper conductors shall be used.

iii. Initiation Devices: Utilize addressable devices for all new initiation devices, unless specifically approved otherwise by the Government.

iv. Notification Devices: Except as permitted by the Government, install speaker-strobes (or separate speakers and strobes) for all new notification devices. The strobe shall have an amber lens with “ALERT” and a clear lens with “FIRE” lettering. In this manner, these devices can be used for augmenting the mass notification system for the island and will not be dedicated to fire alarm alone.

Also provide a means of activating the “ALERT” strobe.

v. The circuitry configuration for initiation and notification devices may be class B unless specified otherwise for a particular project or unless specified otherwise by the Government.

vi. Wiring must also comply with NFPA 72 (National Fire Alarm Code) and NFPA 70 (National Electrical Code). Materials and methods must comply with the latest edition of Unified Facilities Criteria UFC 3-600-01. (Design: Fire Protection Engineering for Facilities) and ADA Accessibility Guidelines for Buildings and Facilities (ADAAG).

vii. All fire alarm wiring is to be in conduit. Utilize EMT conduit in dry areas where permitted by Code.

viii. The Contractor must supply a NICET level 2 certified fire alarm technician to make all final connections at the fire panel and to supervise all final connections at all field devices.

ix. All junction boxes which contain fire alarm wiring must be painted red.

The Contractor shall notify the Government of the proposed times and dates of the testing, at least 7 working days prior to any tests of the fire alarm system, to allow the Arsenal Fire Inspector and COR the opportunity to witness the test of the system. The Government shall have final approval of the times and dates of the tests.

xii. All testing of fire alarm systems which involves activation of the speakers, horns or strobes in a building must be conducted after normal working hours.

c. Construction Power: The Government will allow reasonable usage of electric utilities during construction, in proportion to the size of project and subsequent possible necessity for powering contractor portable trailers and such items for larger projects. If temporary connections to the Island utility system is necessary for construction (other than utilizing existing 120 volt convenience outlets), the contractor shall propose in writing the temporary wiring changes. The Government will have final approval over the method of connection and may require the contractor to establish circuit breaker or fuse protection designed to limit the use of utilities depending upon electric system capacity at the point of connection. The contractor shall practice energy conservation in the use of Government utilities, and will turn off equipment when not needed. The contractor temporary connections shall not pose a safety hazard to personnel or facilities on the Island.

d. Coordination: The designer will ensure that all proposed construction work affecting on-going private utility contracts will be coordinated with the Directorate of Contracting. In addition, the designer will ensure that any construction work affecting Government owned communications systems will be coordinated with the Directorate of Information Management at Rock Island Arsenal.
