I would check the CD's to see what the construction type is first. If the facility is more than 2 stories, the floor/ceiling assembly is required to be rated and the open grated concept is probably not feasible. Protected construction may also be required due to the allowable area.

One of the things that I am considering bringing to his attention is the possibility of turning their upper cell walkway into an open grate flooring of 4' or less. I was pretty sure that this would eliminate the need for sprinklers under these walkways but I wanted to substantiate it before I presented it. NFPA 13 02 edition 8.5.5.3.1 states " Sprinklers shall be installed under fixed obstructions over 4ft wide such as ducts, decks, open grate flooring, cutting tables, and overhead doors". Am I correct in assuming that if these "floors" are 4' or less that sprinks will not be required? I thought that I remembered that there were other requirements such as percentage or size of openings similiar to the meshing in nursing home curtains but I can't find it anywhere. Any help is appreciated.
