APPENDIX D
DOD MINIMUM ANTITERRORISM STANDARDS FOR EXPEDITIONARY AND
TEMPORARY STRUCTURES
D-1
SITE PLANNING STANDARDS. All the standards that are unique to
expeditionary and temporary structures pertain to site planning. Integrate operational,
logistic, and security requirements into the overall configuration of structures,
equipment, landscaping, parking, roads, and other features. The most cost-effective
solution for mitigating explosive effects on expeditionary and temporary structures is to
keep explosives as far away as possible. This is especially critical for these types of
structures because hardening may or may not be possible. Dispersed layouts reduce
risks from a variety of threats by taking full advantage of terrain and site conditions;
therefore, nothing in these standards is intended to discourage dispersal. Costs and
requirements for expeditionary and temporary structure hardening are addressed in
UFC 4-020-01.
D-1.1
Standard 1. Standoff Distances. The standoff distances apply to all
new and existing DoD expeditionary and temporary structures covered by these
standards except as otherwise stated below. The standoff distances are presented in
Table D-1and illustrated in Figure D-1. Except as otherwise required in these
standards, where the standoff distances in Table D-1 can be provided, use conventional
expeditionary and temporary structures without a specific analysis of blast effects.
Where those distances are not available, analysis of the structure by an
engineer experienced in blast-resistant design is required and hardening will be applied
as necessary (in those cases which permit structure hardening) to mitigate the effects of
the explosives indicated in Table D-1 at the achievable standoff distance to the
appropriate level of protection.
The appropriate levels of protection for each structure category are shown
in Table D-1, and are described in Table 2-2 and in UFC 4-020-01. Note that container
structures and pre-engineered buildings respond similarly to other buildings, so they are
separated from the other expeditionary and temporary structures below. Of the
remaining expeditionary and temporary structure types, the two structure types in Table
D-1 respond in fundamentally different ways to explosive effects. Standoff distances in
Table D-1 reflect those differences.
D-1.1.1
Controlled Perimeter. Measure the standoff distance from the closest
point on the structure exterior to the controlled perimeter.
D-1.1.1.1
Container Structures and Pre-engineered Buildings. For these
structures, apply the guidance for new and existing buildings in Appendix B.
D-1.1.1.2
Fabric Covered and other Expeditionary or Temporary Structures.
Provide the standoff distance from Table D-1 for the applicable structure category.
