I have a project that consists of a concrete deck and a solid decorative wooden ceiling suspended about 1-foot below the deck. I'm trying to determine if this condition would create a combustible concealed space per Section 8.15 of NFPA 13 (2013 edition). The section touches on the construction of structural elements, but not really the construction of the ceiling itself.
Unfortunately, I have not been able to verify the supporting structure of the ceiling as is difficult to access above due to its age and level of ornate detail. I also question the feasibility of being able to protect above this ceiling for those reasons.
If the space is considered a combustible concealed space and the preference is to omit sprinklers from the space, is the course of action at that point to increase the hydraulically remote area to 3,000 sf and omit protection?
