Item 2 allows 22" when the obstruction clearances of 10.2.7.2 can be satisfied which should be easy enough at a 2" difference in elevation.

All the sections I note are from the '16 edition of NFPA 13 Obstructed construction per §3. 7. 1, §A. 3. 7. 1(1), as you have concrete beams, spaced between 3' and 7½" apart.

ZjQcmQRYFpfptBannerEnd Jackie, I echo the thoughts of Anthony, Matt, and my good friend Cliff. All the sections I note are from the '16 edition of NFPA 13 * Obstructed construction per §3.7.1, §A.3.7.1(1), as you have concrete beams, spaced between 3' and 7½" apart. * Sprinklers required in each bay, per §8.6.4.1.2(3), as it's not possible to reach the 22" maximum in (1) or (2) as the beam depth is 24" Hope that lines up with what others have to say. And, except for the section numbers this is fairly unchanged in the '22 edition. sincerely, Ken Wagoner, SET Parsley Consulting 500 West Mechanic Street Harrisonville, Missouri 64701-2235 Phone: (760) 745-6181 Visit the website<https://urldefense.com/v3/__https://linkprotect.cudasvc.com/url?a=http*3a*2f*2fwww.parsleyconsulting.com*2f&c=E,1,Y5zKJKPEh1mBEBqSR-VE9cUKl5y-eyP8BpvmE_5j9ZqW2eJbNphYzrCMBZ-2YuX6d-RRkHI4gQ1FV-cvOeCfRC58uZS9NiToZv2mx7909oCqLvCW_n5hDHeK&typo=1__;JSUlJQ!!FaxH778!YFCUu-j6odPrO_X-MFMR8WKY_8xg-wufPwm_LbKuEFfCR6JMnCumBY8kS_LdFkJ8r0qgPptUttn45O4JDvdP$> This message is for the named person's use only.
