I can read this from the manual myself. I was looking for something a little more specific. When is it External Circulation? When it is the only current (vs possible) way (public vs private) to get to a space? Does it have to be the minimum allowed by code/ ANSI? Where do you stop the extent of it (at the door, 1' past it, etc.)?
What is the maximum allowed for a door setback in sf?
"certain Building Service Areas and certain areas within an Unprotected Exterior Opening" Which ones?
When can exterior space be counted as Building Common area? We have a building with extensive terraces and ground floor arcades and need to know when or how much of these spaces can be counted in the calculations? There is an area under the overhang of the building at the entrance to the main lobby that is at least 60' x 60'. Can all or some portion of this be counted? There is also an overhang that runs the perimeter of the building that has retail entrances off of it. Can all this be counted regardless of there widths? Balconies or terraces above grade?
