    8'-0" max spacing perpendicular to deck slope

    Following off Travis, it would appear to be 8.6.2.2.1 (a) "Combustible Unobstructed with exposed members greater than 3' O.C." and also with a sloped ceiling so don't forget your 30% design are increase.

    Mixing ordinary and intermediate temperature fire sprinkler heads in light hazrd occupancy

    Fully agree with SprinklerDesigner2, check their approvals from AHJ and their submitted shop drawings and if they do not show the varied sprinkler temps that were installed, request they follow the documents. I'm only a layout technician, but this is something we would never do within our company.

    Surveying Existing High Deck Systems?

    Thank you all for the suggestions. Chevy you hit the nail on the head. I have a telescopic pole for doing surveys and now I just need to make a little adapter for thread on the bottom half of a split ring. I'll post pics of the final product when I finish. Thank you for the help again everyone.

    Surveying Existing High Deck Systems?

    I've been working in the industry for 8 years now, and still I have not found a good way to confirm pipe sizes on existing buildings in instances where say the deck is 30' up. Eyeballing it is not good enough and throwing a 100' tape over it and measuring is only a semi accurate method. Where I...

    ESFR system adjacent to existing .25/3000 System

    Sdpaddler50, Thank you, I had assumed the same, but the owner asked as he does not wish to erect the draft curtain. As for the building height the building is only 30'-7" at it's peak, the 49'10" gap is the piece of wall missing, I've attached an image to give better detail on the situation...

    ESFR system adjacent to existing .25/3000 System

    A question has been posed at an existing manufacturing building, half the building is being converted into storage under an ESFR system. Both systems are divided by a full height wall except at a 49'-10" section. As per NFPA 13 2010 8.4.6.4.1 "Where ESFR sprinkler systems are installed adjacent...

    Room w/out ceiling, partial height walls, how to cover properly?

    Thank you all, this is exactly what we were looking for. We've replied to the engineer with this information and also sent a request to NFPA to confirm this for us. Appreciate the quick responses and all your help. Jon

    Room w/out ceiling, partial height walls, how to cover properly?

    Sorry the second code 8.15.23 is a 2013 code.

    Room w/out ceiling, partial height walls, how to cover properly?

    Travis, That is exactly what the engineer is claiming, that the ceiling constitutes the one side. NFPA 13 2010 8.15.1.5 NFPA 13 2010 8.15.23 Is there a code in IBC, IFC, or NFPA we can give back to him to disprove his point? The work is done in Des Moines, IA USA Thank you, Jon

    shadowed floor area NFPA 13R

    Dale, From your description the way to figure the area is a simple matter in most cases. I've attached a drawing to give an example, each shaded area is a shadow created from spray pattern in the bathroom. To calculate their area is a simple matter of figuring the area of a triangle...

    Room w/out ceiling, partial height walls, how to cover properly?

    Removal of existing upright sprinklers located in non-combustible concealed space above ceiling

    We have an AHJ here in Iowa that requires the uprights left in place within the mall of his jurisdiction. He has required this for protection of the space during construction and there were issues with seasonal stores taking down ceiling tiles to accommodate their own needs. When we designed the...

    NFPA 25 - Main Drain Test

    Perhaps try an Air Gap? When we had a similar situation we had an engineer rule that a 2'-0" long piece of 8" was to be placed before the 6" building drain. We then placed our 2" main drain 1'-0" down into this 8" perhaps check with your plumber or engineer about this. Might work for this...
