the only concern is that the three rooms together have 55 occupants. in scouring my books, i ran across this in the 2009 IBC Q&A, section 304; "Although Section 304.1 for Group B occupancy lists both "Educational occupancies for students above the 12th grade" and "training and skill development", these classifications may still describe the "use" of the space, but because the occupant load exceeds 50 people, this space must be treated as a Group A assembly occupancy".
whoa! how did they get there? i know there are exceptions for small Group A Occupancies that could be classified as Group B, but nothing in the definition of Group B that forces it the other way.
and in the 2009 IBC Handbook, Section 304, i find this; "Educational occupancies above the 12th grade, including college classrooms and training rooms for adult education, are considered Group B uses. This designation is not necessarily incumbent on the number of students (occupants) in the room." so from this, i would think my initial reaction is correct.
so, which is it? did i miss something? appreciate your insight! thanks!
