Ceiling requirements #1:
uThis program a
umes a constant ceiling height throughout the entire
Warea to be analyzed.
If ceiling heights vary, you must analyze each
\area that varies from the co
on height of the other areas found in the
Ystructure.
(Example:
A structure has a co
on ceiling height of 8 ft. through
X9 of it's 12 r
Two of the 'o

Utwo areas can be combined in one analysis.
