We are looking to turn our Dance Studio into a performance space for our Spring Arts Festival. The Facilities Manager does not currently have a seating capacity for the room and while he works on obtaining that from the Fire Marshal, I figured Id ask if anyone knows what goes into determining that number. The room is 30' x 50' with double doors (both with exit sign above them) at opposite sides of the room. One door goes back into the Hallway, one goes outside. There is also a single door that goes into the Drama Room that also has two points of egress. This is a fairly new space (5 years) so there is a sprinkler system, HVAC all that good stuff. For this specific event we will have a performance space that is roughly 19'deep x 24'wide and keep 24" between rows with at least a 4' aisle between seating sections. We are going to set up the same folding chairs that are set up for Graduations and Assemblies in the Gym (they do not lock together...) Is there anything else to take into consideration?
