Re: [EXTERNAL] Noncontinuous obstructions More than 18" down

It sounds like the architect is working hard to inspire kids with his beautiful ceiling design... From the little information you gave, it may be more like a cloud ceiling than a traditional obstruction. See section 3.3.5.1 for the definition, and then 8.15.1.2.1.3 for criteria. You may also wan

Seems like there's been a resurgence in activity in the list recently. Makes me happy and I know it would have made George Church happy. So in the spirit of George, or perhaps channeling George's spirit, if you are an active participant or a lurker that finds value in this exchange and you're a mem

RE: [EXTERNAL] Noncontinuous obstructions More than 18" down

Does "at least 1 inch of space between each panel" mean several feet of space between each panel, or does it mean just a couple of inches. To me, it sounds more like you would have to treat them as grouped obstructions and protect underneath. -Kyle M -Original Message- From: Sprinkler

RE: Bathroom Chase

At first I thought this was Skyler and I couldn't figure out why he was disagreeing with me when I was agreeing with him. So then, Cecil, are you of the opinion that the entire area above the ceiling would need sprinklers? That doesn't make sense at all. We're essentially talking about a mecha

Noncontinuous obstructions More than 18" down

Seeking others opinions I'm doing an Elementary school where in the commons area they have 4ft. by 8ft. tectum ceiling panels space throughout with at least 1" of space between each panel. These panels are slopes with the roof in one direct and then away from the roof in another. A8.6.5.3.3

Re: Bathroom Chase

While I think the logic path you follow for covering half a remote area one direction and then another makes some sense, the Committee was not willing to consider a two-sided scenario. The rule was written such that the area above the ceiling is only exposed on one side. This way, going two o

Re: 13R Balcony Protection - Any Depth Requirements?

FWIW this was born out of the fire code as a hedge against exposure fires from grilling, primarily, probably patio heaters and what not as well now. It then migrated into 13R due to the near universal pairing of IBC/IFC with 13R. IFC/IFC commentary unfortunately doesn't give a ton of wiggle e

13R Balcony Protection - Any Depth Requirements?

I notice that 13R 6.6.5.1 (2013 ed) requirement for sprinkler coverage for exterior balconies does not have a depth requirement unlike the 4ft rule found in 13. I have some apartments I'm bidding with a balcony at the upper level and the overhang is 3 ft.over the balcony. I'm going to put sprinkler

RE: Bathroom Chase

Brian, I agree with Skyler here. The picture may not look like what you're doing, but the book would be hard to carry if there were a figure representing every scenario. The intent seems to apply though: You've got a space that is sprinklered only because it is open to an adjacent sprinklered s

IMHO, access for maintenance is not access for storage. Check out the door schedule. Maybe it is 2'-0" wide and locked for maintenance personnel only? On Fri, Feb 12, 2021 at 10:17 AM JD Gamble via Sprinklerforum < sprinklerforum@lists.firesprinkler.org> wrote: > But it has a door, most likely

Bathroom Chase

There's a chase between (2) bathrooms that has an access door which I assume is for maintenance. The drywall stops 6" above ceiling, basically making the entire structure above the ceiling "open". I can't imagine we would need to provide protection at the deck throughout the whole area. Seems li
