Complete Compiled Specification.pdf - Peck Ormsby Construction

I. All materials and equipment installed under this work shall be properly and adequately
supported from the building structure except where ceiling construction or other provisions
are specifically designed to support them. Support systems shall provide a safety factor of
four. This shall apply to chains, hangers, anchors, clamps, screws, structural iron, and all
other hardware and appurtenances associated with the support system.
J. Rough-in for communications outlets for phone and data systems shall consist of a 4" square
deep (4SD) box with a single gang mud ring. A minimum of 1 1/4 inch conduit will be used
for all TELCOM location pathways, and ALL conduits will be routed in the ceiling space and
not in the concrete slab. All conduits will be run from the location in one complete and
continuous path to the cable tray and bonded to the cable tray as per ANSI/TIA/EIA
Standards and the National Electric Code. Refer to data specification for additional details.
K. Maintain the following minimum separations from voice and data cables. Power conduit -
12", transformers and motors - 40", fluorescent lighting - 12". Coordinate with the voice and
data installer to assure these separations are met.
L. All new floor mounted electrical equipment including, but not limited to: Transformers,
Switchboards, MCC’s, Switchgear, Switches, UPS, PDU’s and Generators; shall have
concrete housekeeping pads installed. All Concrete pads shall be as indicated on the
drawings or 4 inches high above finished floor, extending to 4 inches beyond the width and
depth of the Equipment base; pad dimensions indicated on the drawings shall take
precedence in all cases.
3.3 LOW VOLTAGE WIRING METHODS:
A. Provide conduit homeruns complete for all low voltage systems in the new addition and office
remodel area. Plenum cabling will not be acceptable.
B. Provide plenum rated cabling for fire alarm, access control, security, and PA system wiring in
existing school areas with hard ceiling (classrooms, hallways, restrooms, storages, etc.).
Refer to the drawings for details. Wiring to be concealed above ceiling and supported on the

data outlets, and sized as needed for other systems. Drawings notes shall take precedence.
Raceways for phone and data cable shall be sized based on the number of cables in
accordance with the division 17000 specification.
D. Furnish and install all necessary sleeves and raceways to permit the installation of signal
cables (specific attention is called to non-contiguous ceiling spaces) to the appropriate
equipment termination point. Provide sleeves through all fire-rated walls and partitions. No
outlets of any type shall be left without a raceway system or accessible ceiling path to their
termination point. Verify that raceway sizes and quantities are appropriate and will have at
least 50% spare capacity after all cables are initially installed. Provide at least one empty
spare conduit to each area, sized to handle future needs.
