Re: Apartment Crawl Space

This is indeed the opinion of the 13R technical committee. The problem is that it isn’t their decision to make. That belongs to the building code and it says it is possible with the right combination of variables. Same things applies to NFPA 13 equipment that the ENTIRE building must be prote

Re: Apartment Crawl Space

I disagree completely with this simplified approach. It is possible to mix the two system types but there are multiple variables that come into play, the most significant being it must qualify as a separated mixed occupancy and it must contain the right combination of occupancies. The building

Duane, I respectfully question that. Section 1.1 of the 2016 NFPA 13R states: "This standard shall cover the design and installation of automatic sprinkler systems for protection against fire hazards in residential occupancies up to and including four stories in height in bu

Re: Apartment Crawl Space

You have to follow the IBC/IFC first in most areas. That is going to point you to one or the other, unless they get creative with horizontal and vertical separations. A 3 story type V-A construction building with R2 occupancy (IBC code) of 36k sq ft per floor is going to be NFPA 13 unless they

RE: Apartment Crawl Space

Duane: Having taught NFPA sprinkler seminars for 8 or 9 years and having served on the AUTRSS for 5 cycles, I am reasonably certain that this isn't accurate. NFPA 13R has had various explanations in A.1.1 over the years, but the current one states, "NFPA 13R is appropriate for use as an alte

RE: Apartment Crawl Space

Brian, NFPA and NFA seminars. The definition of 13R is for up to and including four floors. It doesn't prohibit the building from having more floors just like if the first floor was mercantile or business (like a hotel). You would design the first floor, fifth floor, and attic as NFPA 13,

RE: Apartment Crawl Space

According to NFPA you can do a 13-R for the first four floors and a 13 system on the 5th floor and attic. I think you need to look at the IBC/IRC to see if there are building code requirements in the crawl space (assuming a normal crawl space). Duane T. Fox, Jr., CFPS, CFI, CFPE Asst Chief, Te

RE: Apartment Crawl Space

Brian, Per 13, crawl spaces are generally not required. See NFPA-13, 2016 Ed, page 92, 8.15.6.2. As for interstitial spaces in combustible const., as often found in residential work, sprinklers will be required. You would have been in luck with 4 floors or less, but not 5. Good luck. John O'C

Apartment Crawl Space

Looking at a (5) story apartment building so I assume it would need to be per NFPA-13 correct? With that being said is there anything in the Standard that addresses the crawl space underneath? Concealed Space? Brian Harris, CET BVS Systems Inc. Design Manager bvssystemsinc.com

I've tried to refind that fire modeling you did Roland a couple three centuries ago re how the deeper the pocket the better. It makes sense how if you have a huge mass of cool air above the area of the opening the ceiling jet just keeps on trucking like the opening wasn't there. It was Teach
