APPENDIX A
DEFINITIONS
Access control. For the purposes of these standards, any combination of barriers,
gates, electronic security equipment, and/or guards that can deny entry to unauthorized
personnel or vehicles.
Access road. Any roadway such as a maintenance, delivery, service, emergency, or
other special limited use road that is necessary for the operation of a building or
structure.
Billeting. Any building or portion of a building, regardless of population density, in
which 11 or more unaccompanied DoD personnel are routinely housed, including
Temporary Lodging Facilities and military family housing permanently converted to
unaccompanied housing. Billeting also applies to expeditionary and temporary
structures with similar population densities and functions.
Building hardening. Enhanced conventional construction that mitigates threat hazards
where standoff distance is limited. Building hardening may also be considered to
include the prohibition of certain building materials and construction techniques.
Building separation. The distance between closest points on the exterior walls of
adjacent buildings or structures.
Collateral damage. Injury to personnel or damage to buildings that are not the primary
target of an attack.
Collaterally protected construction. Construction that provides protection against
near-miss detonations of large general purpose military bombs.
Command vehicles. Vehicles operated by installation commanders and/or their
designated staff.
Container structures. Structures built using shipping containers that are designed to
withstand structural loadings associated with shipping, including Container Express
(CONEX) and International Organization for Standardization (ISO) containers. Testing
has shown that these structures behave similarly to buildings for the purposes of these
standards.
Controlled perimeter. For the purposes of these standards, a physical boundary at
which vehicle access is controlled at the perimeter of an installation, an area within an
installation, or another area with restricted access. A physical boundary will be
considered as a sufficient means to channel vehicles to the access control points. At a
minimum, access control at a controlled perimeter requires the demonstrated capability
to search for and detect explosives. Where the controlled perimeter includes a
shoreline and there is no defined perimeter beyond the shoreline, the boundary will be
at the mean high water mark.
