Conventional construction. Building construction that is not specifically designed to
resist weapons or explosives effects. Conventional construction is designed only to
resist common loadings and environmental effects such as wind, seismic, and snow
loads.
Conventional Construction Standoff Distance. The standoff distance at which
conventional construction may be used for buildings without a specific analysis of blast
effects, except as otherwise required in these standards.
Design Basis Threat. The threat (aggressors, tactics, and associated weapons, tools,
or explosives) against which assets within a building must be protected and upon which
the security engineering design of the building is based.
DoD building. Any building or portion of a building (permanent, temporary, or
expeditionary) owned, leased, privatized, or otherwise occupied, managed, or controlled
by or for DoD. DoD buildings are categorized within these standards as uninhabited,
inhabited, primary gathering and billeting.
DoD Components. The Office of the Secretary of Defense (OSD); the Military
Departments (including their National Guard and Reserve Components); the Chairman,
Joint Chiefs of Staff and Joint Staff; the Combatant Commands; the Office of the
Inspector General of the Department of Defense; the Defense Agencies; the DoD Field
Activities; and all other organizational entities within DoD.
DoD personnel. Any U.S. military, DoD civilian, or family member thereof, host-nation
employees working for DoD, or contractors occupying DoD buildings.
Effective Standoff Distance. A standoff distance less than the Conventional
Construction Standoff Distance at which the required level of protection can be shown
to be achieved through analysis or can be achieved through building hardening or other
mitigating construction or retrofit.
Emergency Vehicles. Vehicles such as fire trucks and ambulances that are critical to
emergency response, and for which close proximity to inhabited buildings or
containment therein is essential.
Expeditionary structures. Those structures intended to be inhabited for no more than
1 year after they are erected. This group of structures typically include tents, Small and
Medium Shelter Systems, Expandable Shelter Containers (ESC), ISO and CONEX
containers, and General Purpose (GP) Medium tents and GP Large tents, etc.
Fabric covered structures. A construction type that can be identified by wood or
metal (usually aluminum) posts or load-bearing frames with some type of fabric (such as
canvas) stretched or pulled over the posts or frames. Examples of the types of
structures that should be considered under this classification of structures include
Frame-Supported Tensioned Fabric Structures (FSTFS); Tent, Extendable, Modular,
Personnel (TEMPER Tents); and Small and Medium Shelter Systems (SSS and MSS);
General Purpose (GP) Medium tents and GP Large tents; and air supported fabric
