UFC 4-010-01

based on the standoff distances and explosive weight associated with controlled
perimeters in Table B-1. Where those standoff distances are not available, and since
moving existing railroads may be difficult and prohibitively expensive, ensure that there
are procedures in place to prohibit trains from stopping in the vicinity of inhabited
structures.
C-1.7
Recommendation 7. Access Control for Family Housing. For new
family housing areas, provide space for controlling access at the perimeter of the
housing area so that a controlled perimeter can be established there if the need arises
in the future.
C-1.8
Recommendation 8. Standoff for Family Housing. For new family
housing construction, maintain a minimum standoff distance of 25 meters (82 feet) from
installation perimeters and roads, streets, or highways external to housing areas.
C-1.9
Recommendation 9. Minimize Secondary Debris. To reduce the
hazard of flying debris in the event of an explosion, eliminate unrevetted barriers and
site furnishings in the vicinity of inhabited structures that are accessible to vehicle traffic.
Revet exposed barriers and site furnishings near inhabited buildings with a minimum of
1 meter (3 feet) of soil or equivalent alternative techniques to prevent fragmentation
hazards in the event of an explosion.
C-1.10
Recommendation 10. Building Separation. This recommendation
applies to new buildings and is established to minimize the possibility that an attack on
one building causes injuries or fatalities in adjacent buildings. The separation distance
is predicated on the potential use of indirect fire weapons as identified in UFC 4-010-02.
C-1.10.1
Billeting and Primary Gathering Buildings. For all new billeting and
primary gathering buildings, ensure that all adjacent inhabited buildings are separated
from the billeting and primary gathering buildings by at least 10 meters. Where it is
necessary to encroach on those building separations, analyze the billeting and primary
gathering buildings and provide hardened building components as necessary to mitigate
the effects of the indirect fire weapon identified in UFC 4-010-02 to the low level of
protection. Levels of protection are described in Table 2-1 and in the DoD Security
Engineering Planning Manual. The indirect fire weapon should be assumed to detonate
at a distance from the target building of one-half of the separation distance.
C-1.10.2
Other Inhabited Buildings. There are no minimum separation distances
required for antiterrorism purposes for inhabited buildings other than billeting and
primary gathering buildings.
C-2
STRUCTURAL AND ARCHITECTURAL DESIGN. The following
additional measures, if implemented, will significantly enhance building occupants'
safety and security with little increase in cost. Consider these measures for all new and
existing inhabited buildings.
C-2.1
Recommendation 11. Structural Redundancy. Unexpected terrorist
acts can result in local collapse of building structural components. To limit the extent of
collapse of adjacent components, utilize highly redundant structural systems such as
