On a seismic job, I have always designed such that there is either a flexible drop or a hole 1" larger than required for the sprinkler head in gypsum board ceilings. I was thinking that practice was based on NFPA 13, but as I look for it now, I do not see it. Instead, it appears this requirement is found in ASCE 7.
While NFPA 13 says nothing of ASCE 7 regarding seismic protection, the IBC states that all non-structural components be protected in accordance with ASCE 7. As I understand it, the protection requirements of NFPA 13 were developed to comply with the ASCE 7 requirements. Soooo, my question is, am I required to provide this 1" clearance at sprinkler drops in rigid ceilings or does NFPA 13's silence mean I am not held to this?
