threat exclusion, the flow chart branches to Element <35>, otherwise to
Element <36>.
<35> Estimate building interior ingress time.  The on-foot ingress
time between the exterior of the building and each interior shell layer can
be estimated using Figure 8. The preliminary building layout plan established
under Element <2> can be used to estimate the distances between interior
layers.  In general, the shortest distance should be used.  It is possible
that there may be some difference in the time to reach one building component
relative to another.  For example, attacking and entering through the ceiling
of a secured area may mean added time to climb the extra floor relative to a
wall or door attack.  Generally, the time differences involved are small and
one can use the minimum time over all components.  On the other hand, a
separate ingress time is required between each interior layer and the last.
If there is only one interior layer (as shown in Figure 6), then only one
time is required between this layer and the exterior of the building.  If
there are more interior layers, a separate time is required for each.  These
ingress times should be inserted in the appropriate slots under Column E of
the "Interior Layers" portion of the new design worksheet (Table A-1) and
Column H of the retrofit worksheet (Table A-2).  Note in the worksheet, that
Interior Layer No. 1 is the innermost layer, Interior Layer No. 2 is the
next, etc.
<36> Estimate building interior ingress plus egress time.  If
threat containment rather than exclusion is permitted, both the ingress into
and egress out of the building can be accounted for.  The on-foot ingress
time can be estimated using Figure 8 with an estimate of the distance
involved.  The egress time may be shorter or longer than shown in Figure 8
depending on the weight or volume of the assets being stolen.  The egress
distance may also be different depending on the availability of doors,
windows, etc., that may be opened from the inside.  A separate ingress and
egress time is required between each interior layer and the last.  If there
is only one interior layer (as shown in Figure 6), then only one time is
required between this layer and the exterior of the building.  If there are
more interior layers, separate ingress and egress times are required for
each.  These times should be inserted in the appropriate slots under Column E
of the "Interior Layers" portion of the new design worksheet or Column H of
the retrofit worksheet appropriately.  Note in the worksheet that Interior
Layer No. 1 is the innermost layer, Interior Layer No. 2 is the next, etc.
<37> Does facility type have minimum construction requirements?
Minimum prescribed DoD security-related construction requirements exist for
vaults and strongrooms; sensitive compartmental information facilities; arms,
ammunition, and explosive facilities; and nuclear weapons facilities.  If the
facility being designed is one of these, the flow chart branches to
Element <38>, otherwise to Element <41>.
<38> Select construction of first layer to meet minimum.  Paragraph
5.4 presents the minimum prescribed construction for each building component
(walls, roof, floor, doors, utility opening).  These should be entered into
