 MIL-HDBK-1013/10
be of great value in designing walls, doors, and the roof of sentry booths and
gatehouses.
Environmental Control. Conduct an analysis of the ambient
4.3.2.5
temperatures to determine HVAC requirements. Consider heating due to
electronic and electrical systems or fixtures, and security support equipment
inside the structure. Determine HVAC requirements based on NAVFAC HVAC
criteria for the local area. Insulate the walls and ceilings as required by
NAVFAC criteria for the local area. As a minimum, provide cold water and soil
lines if toilet facilities are required.
4.3.2.6
Lighting. Exterior lighting for sentry booths and gatehouses
shall be 2.0-footcandle (20-lux) horizontal illumination during normal
visibility conditions, and 6 inches (154.4 mm) above ground level. To
minimize exposure of security personnel, use "glare protection" lighting at
entry points. (The lighting will be directed at the gates with the gatehouse
allowed to be in the shadows.) The interior lighting will be diffused
lighting and designed with dimmer controls to aid with night vision and
provide additional security to the occupants. Consider the use of a night
light unit with a red lens. Connect lighting to a standby power source at the
restricted area.
4.3.2.7
Grounding. Provide grounding protection. Refer to the National
Fire Protection Association (NFPA) 78, Lightning Protection Code.
4.3.2.8
Fortification.
Normally fortification requirements are driven by
two factors: the local area threat level, and the requirements of the
facility commander. Refer to MIL-HDBK 1013/1 for design criteria regarding
attack hardening and ballistic resistance. When gun ports are required for
sentry booths or gatehouses, consider the compatibility of gun ports to type
of weapons, and attachments to be used (i.e., night vision scopes).
4.3.3
Prefabricated Structures. State-of-the-art prefabricated sentry
booths and gatehouses offer an alternative to site-built structures.
Prefabricated structures range from simple weather protection, to high-tech
ballistics resistant. Resistance covers level I - level V and range from 1-
to 60-minute forced entry resistance. Prefabricated structures can be ordered
prewired to meet any electrical requirements desired. They can be procured
with standard heating and air conditioning features. Additional options
include gun ports, card pass trays, intercoms, and toilet facilities. A
typical prefabricated structure is shown in Figure 32.
A thorough site analysis and review of operational requirements
for the area involved must be accomplished prior to initiating design of
sentry booths or gatehouses. Once the requirements are determined, the design
engineer should request cost estimates from several manufacturers for the
prefabricated structure. Each manufacturer offers a number of standard sizes
or will custom build to specifications. A partial list of manufacturers can
be found in Appendix A. Concurrently, an estimate for new construction of the
