APPENDIX B
DoD MINIMUM ANTITERRORISM STANDARDS FOR NEW AND EXISTING
BUILDINGS
B-1
SITE PLANNING. Operational, logistic, and security requirements must
be integrated into the overall design of buildings, equipment, landscaping, parking,
roads, and other features. The most cost-effective solution for mitigating explosive
effects on buildings is to keep explosives as far as possible from them. Standoff
distance must be coupled with appropriate building hardening to provide the necessary
level of protection to DoD personnel. The following standards detail minimum standoff
distances that when achieved will allow for buildings to be built with minimal additional
construction costs. Where these standoff distances cannot be achieved because land
is unavailable, these standards allow for building hardening to mitigate the blast effects.
Costs and requirements for building hardening are addressed in the DoD Security
Engineering Planning Manual.
B-1.1
Standard 1. Minimum Standoff Distances. The minimum standoff
distances apply to all new and existing (when triggered) DoD buildings covered by these
standards. The minimum standoff distances are presented in Table B-1 and illustrated
in Figures B-1 and B-2. Where the standoff distances in the "Conventional Construction
Standoff Distance" column of Table B-1 can be met, conventional construction may be
used for the buildings without a specific analysis of blast effects, except as otherwise
required in these standards. Where those distances are not available, an engineer
experienced in blast-resistant design should analyze the building and apply building
hardening as necessary to mitigate the effects of the explosives indicated in Table B-1
at the achievable standoff distance to the appropriate level of protection. The
appropriate levels of protection for each building category are shown in Table B-1, and
are described in Tables 2-1 and 2-2 and in the DoD Security Engineering Planning
Manual. For new buildings, standoff distances of less than those shown in the
"Effective Standoff Distance" column in Table B-1 are not allowed. For existing
buildings, the standoff distances in the "Effective Standoff Distance" column of Table B-
1 will be provided except where doing so is not possible. In those cases, lesser standoff
distances may be allowed where 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 as described in these standards and in the DoD
Security Engineering Design Manual.
B-1.1.1
Controlled Perimeter. Measure the standoff distance from the controlled
perimeter to the closest point on the building exterior or inhabited portion of the building.
B-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 B-1 apply. If there is no controlled perimeter, assume
that the larger explosive weights upon which the controlled perimeter standoff distances
are based (explosive weight I from Table B-1) can access parking and roadways near
