Constructing a Concrete Pad
A concrete pad provides a permanent foundation to anchor the cabinet to the ground while protecting the cabinet from water
damage and other outdoor surface conditions.
Construct a concrete foundation pad for the cabinet at the installation site. Pad construction requires excavating the site,
trenching cable conduit, constructing a form, and casting concrete. Use the Clearfield -supplied cast-in-place template to
provide exact locations for the mounting studs that anchor the cabinet to the pad and to provide the cable conduit locations.
Pad Construction Guidelines
When constructing a concrete pad, observe the following guidelines and refer to the pad drawings for guidance.
Guidelines
Follow these guidelines to ensure proper pad construction. Adjust for local conditions or practices as required.
•
Construct a pad for a stand-alone FAC 900 cabinet configuration with minimum perimeter dimensions of 48 x 72 inch
-
es.
Note:
Be sure to construct an adequate size pad if you may consider adding an EXM later as an expansion.
•
Construct a pad for an FAC 900 in-line configuration with minimum dimensions of 48 x 101 inches.
•
Construct a pad for an FAC 900 L-configuration with minimum dimensions of 77.5 x 99 inches.
Note:
Refer to Space Requirements for more information on cabinet configurations.
•
For a pad that includes an EXM, the location of the EXM conduit box is relative to the FAC 900 cast-in-place template.
• Construct the pad with a minimum height of 6 inches.
• Construct the pad with a maximum of 2 inches above-grade exposure.
•
Use the Clearfield cast-in-place template to provide exact mounting stud and conduit locations.
• Use rebar or wire mesh inside the form to improve pad strength.
• Cast the pad from a single concrete pour. Do not make multiple pours.
• Ensure that the pad is smooth and level across its entire surface.
•
Use 4-inch conduit (maximum) for outside plant cables. See drawings below for entry locations.
•
Use 2-inch conduit (maximum) for AC cable (local power applications only). See drawings below for entry location.
• Include pull cords in all cable conduits.
