I have a building that will have two standpipes, one is an existing combination standpipe (in the stairwell) and the other will have hose valves only (this will be located in the corridor in hose cabinets). There is only one full height stairwell for the entire bldg.
There is one other...
I am looking at a 6 story apt bldg that will need a fire pump to get the 100 psi residual @ top of standpipe. My customer has suggested using a 6" pressure reducing valve in the basement on the 6" main supply to the standpipes vs installing individual pressure reducing valves on each floor.

I have a high rise apt building being retrofitted to an apartment building and am wanting to confirm that Nfpa 13 2010 D.1.1.6 thru D.1.1.6.3 would apply.
My main concern is making sure this applies to high rise buildings.
Thanks!
I spaced @ 130, and I am close to getting it to work with 2.8 k sprinklers.. I have lousy pressure and it's 55'0" in elevation to boot!
Thanks for all your help.
I just got onsite for the first time today and the horizontal "beams" that I said were 8'-0" on center are actually wood collar ties spaced anywhere from 24" to 34" on center. Most are around the 24" mark, tied into the roof joist. (The cad files and pdf plans leave a lot to be desired on this...
It's very old construction. The roof joist are 2'-0" o.c, but they will all be covered up by the new wood plank ceiling, so I am thinking the roof joist are no longer a factor in considering the spacing of the sprinklers, am I correct in that thinking? It's really just a steep pitch ceiling at...
Travis,
Are you sure about the 130 sq. ft spacing? If it falls under Combustible unobstructed with exposed members more than 3'-0" O.C (The exposed beams/ trusses) 8.6.2.2.1 says I can go to 225 sq.ft spacing with a calculated system.
It's 18'-4" to the peak.. Would I still be allowed a...
I have an attic space that is currently protected by BB attic sprinklers and AP sprinklers, it was an unoccupied attic area. Roof pitch is around 12/12.. They are going to occupy this space with offices and install a wood plank ceiling directly onto the roof structure so no roof joist will be...
