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 the
DoD Security Engineering Planning Manual.
D-1.1
Standard 1. Minimum Standoff Distances. The minimum standoff
distances apply to all new and existing DoD expeditionary and temporary structures
covered by these standards except as otherwise stated below. The minimum 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 the DoD
Security Engineering Planning Manual. 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 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.
D-1.1.2
Parking and Roadways. Standoff distances for parking and roadways
are based on the assumption that there is a controlled perimeter at which larger vehicle
bombs will be detected and kept from entering the controlled perimeter. Where there is
a controlled perimeter, the standoff distances and explosive weight associated with
parking and roadways in Table D-1 apply unless otherwise stated below. If there is no
