Thank you, Bob. I didn't consider that. I'll look into and throw it in the mix. It may be something the stakeholders would buy into. Their concern is not being able to access the concealed sprinklers for maintenance. If we kept the sprinkler localized to only the area with exposed framing, that area has a acoustic tile ceiling.

The first and last sprinklers in such a row shall not be over 5 ft from the ends of the partitions. In this scenario you would only provide sprinklers along the exposed walls. Based on what you have described, my opinion is that sprinklers are required in at least a localized manner. Thank you, Bob Knight, CET III 208-318-3057 From: Sprinklerforum [mailto:[email protected]] On Behalf Of Micah Davis, SET Sent: Friday, June 15, 2018 7:35 AM To: SprinklerForum Subject: Concealed Space I have a project that has a concealed space with exposed wood wall framing. I added concealed space sprinklers per 8.15.1.2.1. The engineer is telling me to remove them stating that, since the walls are not load bearing, they are not structural walls. He then references Appendix A for 8.15.1.2.1 that states the requirements to protect the space does not apply for "nonstructural" wood. Has anyone seen this before? What is the opinion of the Forum? I will, of course, defer to the engineer, but I am recommending that the contractor I'm working with get a letter from the engineer clearly stating that they are requesting the sprinkler not be installed.
