PSTE 102038
Construct Above Ground Magazine Storage
McEntire JNGB, Eastover SC
DATE: 7 June 2012
Scope: The project includes construction of a 6,220 SF new metal building in the
munitions storage compound. In addition, approximately 2,400 SF of the existing facility
will be renovated. The construction will entail civil, structural, plumbing, electrical, fire
alarm, and mechanical systems. Contractor to verify all quantities, dimensions and
information with the contract plans and specifications
Civil Narrative:
Civil related work on this project will consist of earthwork, minor site demolition,
placement of the proposed magazine storage building, pavement, walks, utilities and
drainage. Access to the site will be from an existing drive which ties to North Carolina
Road. Prior to demolition and construction, sediment and erosion control measures are to
be implemented. Sediment and Erosion Control measures must be in place as indicated
for prevention of construction sediment from entering the storm drain conveyance
network. Silt fencing shall encompass the limit of disturbance.
Demolition
An existing security fence is located on the site that will be removed such that the
proposed storage building can be completed. An existing 8-inch water line will be
relocated around the proposed storage building. In addition, an existing abandoned 6inch water line will be removed.
Roads, Parking, and Sidewalks
Access to the site will be provided from an existing drive near building 314 that ties to
North Carolina Road. A new 24’ wide heavy duty asphalt service drive will be provided
to connect two existing service drives northeast of the new building. Two additional 12’
wide heavy duty asphalt drive aprons will be provided to the new magazine storage
service access doors.

Permitting
An Erosion Control Submission Notification to SCDHEC will be required for site
disturbance less than 1 acre.
Mechanical:
The mechanical design consists of providing new HVAC equipment for the office and
maintenance areas to meet the facility needs based on maximum occupancy of 30 during
training times and a full time occupancy of 15 during regular operating times.
The renovations will consist of a three (3) new mini ductless split system air handlers and
one (1) variable refrigerant heat pump for rooms 109, 110, and 121 while room 115 will
be provided with two (2) electric unit heaters. The Variable Refrigerant Flow system will
allow for simultaneous heating and cooling and moves heat from one room to another for
increased energy efficiency. The outside condensing unit will be located within an ATFP
enclosure.
The HVAC system will be controlled by DDC controls in compliance with base
standards.
Plumbing:
The plumbing design consists of providing new low pressure compressed air drops for
the maintenance bay room 115.
Electrical:
The electrical design for this project involves the renovation of the existing paint booth
and adjacent bay in building 310 and a new munitions storage building. The electrical
service to the new building will be 100 amp, 120/240 volt, single phase. The existing
electrical service at building 310 is 400 amp, 120/208 volt three phase.
In the new building, circuits will be provided for general receptacle and high bay lighting
loads as well as mechanical systems. Power will also be provided for the roll up doors.
In building 310, new general receptacles will be provided in the renovated portion of
building 310 as required. Ground bars will be provided in the maintenance bay. New
400hz receptacles will also be provided.
Lighting in the new building will consist of linear fluorescent high bay fixtures. Exterior
lighting for the new building will be provided using HID wall paks spaced around the
perimeter of the building. Emergency lighting will be provided by battery ballast
equipped high bay lighting fixtures. Exit signs will be provided by fixtures equipped
with red LED lamps.

The office area lighting in building 310 will consist of 2’ by 4’ recessed fluorescent,
direct-indirect, T8 troffers with electronic ballasts. Pendant mounted fluorescent
industrial strip fixtures will be provided in the equipment and storage areas. Energy
efficient fluorescent high bay fixtures will be provided in the bay areas. Emergency
lighting will be provided by battery ballast equipped fluorescent lighting fixtures. Exit
signs will be provided by fixtures equipped with red LED lamps. Exterior lighting will
be provided using compact fluorescent fixtures.
A UL master label lightning protection system will be provided for the new building.
UPS systems will be provided in the new munitions storage building and the adjacent
storage bunker for the security systems.
Telecommunications:
Telecommunications will consist of a system of junction boxes and empty conduits with
pullstrings. Cabling and equipment will be provided and installed by the government.
Fire Alarm and Mass Notification:
An upgrade to the existing Monaco fire alarm and mass notification system meeting all
current NFPA, NEC, and UFC standards will be installed.
Initiating devices include analog addressable heat detectors, smoke detectors, and manual
pull stations. Any manual or automatic activation of this system will result in all
audio/visual appliances sounding a Temporal 3 alarm throughout the building as well as a
signal being sent to the base fire department via the Monaco digital alarm communicator
transmitter, and a Monaco wireless transmitter. Trouble signals shall be sent to the main
panel as well as the base fire department.
Rate compensating spot type heat detectors shall be the munitions storage room, tool crib
room, and missile maintenance room. Office (room 109) shall be protected by a
photoelectric smoke detector.
Speaker/strobes will be spaced accordingly to provide 15 dBA above ambient sound
pressure level and to provide 0.0375 lumens/sq. ft illumination in the occupiable areas.
Strobes for combination speaker/strobes shall have clear lens; an additional strobe shall
be mounted next to combination device (or stand alone fire alarm strobe) with an amber
lens for mass notification. Additional speakers will be provided in the spaces to provide
an intelligibility score of 0.7 STI (0.8 CIS).
Fire Alarm system is to be monitored for integrity using Class B wiring for initiating
device (style C) and notification appliance circuits (style Y). All fire alarm wiring to be
run in ¾” EMT, and shall be clearly identified as such.

Security System:
The existing munitions shop facility is equipped with Intrusion Detection (IDS) and
Access Control Systems (ACS) which will be modified to meet requirements of the
renovation. The intrusion detection system is by Advantor Systems Corporation and the
access control system is by Advanced Control Concepts. Existing panels for both systems
will be removed, replaced. The new panels will be located above the ceiling in room
109. The two new roll-up doors and two new personal doors to room 110 will be tied into
the IDS as will the new personal door to room 109. Both personnel doors to room 110
and the personnel door to room 109 will be tied into the ACS systems and receive proxy
card readers. Two keypads will be installed in room 110, one at each new personnel
door. One new keypad will be installed inside room 109. Room 110 will also receive two
PIR (motion sensors) and room 109 will receive one PIR.
The magazine storage facility will receive a new IDS and ACS system to be provided by
the previously mentioned companies. The two new roll-up doors and two new personal
doors into the magazine storage facility will be tied into the new IDS. The two personnel
doors will also be tied into the ACS system and receive proxy card readers. Two keypads
will be installed in the new magazine storage facility, one at each new personnel door.
The new facility will also receive two PIR (motion sensors) one at each end of the
building.
