Not sure how everyone else evaluates egress capacity for openings, mainly doors, below is our IBC language. It would seem that GS with AC should have this property with an expression that takes. We need something similar for windows that are used for egress from bedrooms. It would seem that GS should contact a cross-section of users to help with out-of-the-box properties embedded in the program.
( ( {Property:General Parameters/Width} - 2 in ) / .3 )
We use this but get the value in feet and inches, even if the dimension type for length is set to decimal inches. This should be a rounded-up integer value. We are no coder, so we have not been able to find how to convert this date type of length to that which is just an integer value rounded up.
It would seem that this property should be built in, at least in the US market, since we have to show we meet capacity with our doors for that particular use. We need to take some GDL boot camps or other coder camps to understand what needs to be done in the expression; trial and error have been unsuccessful. Trying to incorporate this all into a smart label.
1005.3.1 Stairways. The capacity, in inches, of means of
egress stairways shall be calculated by multiplying the
occupant load served by such stairways by a means of
egress capacity factor of 0.3 inch (7 .6 mm) per occupant.
1005.3.2 Other egress components. The capacity, in
inches, of means of egress components other than stair-
ways shall be calculated by multiplying the occupant load
served by such component by a means of egress capacity
factor of 0.2 inch (5.1 mm) per occupant.
