STANDARDS AND GUIDELINES FOR COMMUNICATION SITES BUILDING/SHELTER DESIGN AND LOCATION CONSIDERATIONS

3.3 BUILDING/SHELTER DESIGN AND LOCATION
CONSIDERATIONS
Pre-fab buildings shelters, cabinets, and vaults may have equipment fully or partially installed prior to
building shipment, requiring additional building specifications to allow lifting with equipment installed.
Weight and size become a consideration if the site has limited access. For shipping, these structures
must meet strict dimensional requirements, including protrusions such as HVAC, RF entry assemblies,
or AC entrances. In the United States, state certification may be required if pre-fab buildings are
manufactured in a different state than deployed. (Similar requirements regarding out-of-state or
province manufacture may also apply in non-domestic situations.)
The following are general considerations regarding sites utilizing a new building or shelter capable of
human occupancy.
• Consideration shall be given to the amount and type of equipment to be housed, along with
adequate space for movement and expansion within the structure. The extent of equipment housed
will typically determine the suitability of prefabricated structures (if desired). See Chapter 6,
“Power Sources,” for electrical power sources and Chapter 9, “Equipment Installation,” for
equipment installation.
• Equipment configuration typically dictates the structure design. The desired size and composition
of a prefabricated shelter shall be considered along with weight in transporting the shelter to the
site.
• All sites utilizing a constructed structure or a prefabricated structure with manned access shall
utilize exterior lighting to some extent. See “Lighting” on page 3-22 for specific details on
requirements for various categories of structures.
