Yeah, already acknowledged that. That’s … not a sprinkler-friendly design, is it? Architects and developers always say, “We don’t need a fire protection consultant, we leave that to the installing contractor.” How are these “closets” built? Are they lockers (i.e. fixtures) or are they framed walls? I’m still not seeing how you can leave them out but looking for an angle here …

Sent from my Huawei Mobile -------- Original Message -------- Subject: RE: ELIMINATION OF SPRINKLERS IN CLOSETS FOR HYDRAULIC CALCULATIONS From: Steve Leyton To: [email protected] CC: The math doesn’t add up – how would eliminating sprinklers for four 10’x10’ closets save 14 sprinklers in the DA? Notwithstanding those metrics, these are not small clothes closets, they are repositories for people’s “stuff”. You have a prevailing ordinary hazard with accessory miscellaneous storage for lack of a better classification. I respectfully disagree that eliminating sprinklers is consistent with the intent of the reference section. 100 sq. ft. packed with camping gear and seasonal toys is a very different condition from an interior closet that might only be 15-25 sq. ft in area.

Sent: Friday, September 21, 2018 11:48 AM To: [email protected] Subject: ELIMINATION OF SPRINKLERS IN CLOSETS FOR HYDRAULIC CALCULATIONS I have a 3 story living condo. There are 4 units which each have an open parking garage under the 2nd floor. Along the back wall are 4 (10sqft ) closets. The engineer is asking for a dry system designed to .15/1950. Just want to know what everyone's thoughts are about not including the sprinklers in these closets. Using the provision 23.4.4.6.2 It would allow me to eliminate 14 sprinklers from my calculation area. Regards Troy
