It doesn't say either - that's the problem with NAVFAC, frankly. It all depends on which FPE you're working with on that particular project and his or her "interpretation" of the issue at hand. I could tell COUNTLESS stories about the inconsistency of enforcement with that agency.

Poured concrete construction, full height concrete walls, floors and roof, every 24'-0" with only 30'-0" front to back.(5200 Sf per floor total) UFC say's you can use 13R, NAVFAC say's NO. UFC say's reduced area for QR heads, NAVFAC say's NO. So we have a two story concrete dorm with a 3000SF design area, 250 GPM hose at the base of riser, and 6" riser and 4" mains, for a job where if we flowed every head between the concrete walls (6) and were overflowing 4 of them, we'd still only need a 3" underground, with 2" mains. Your Tax $$$ at work. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vince Sabolik Sent: Tuesday, May 20, 2008 7:47 AM To: [email protected] Subject: RE: unified facilities criteria question Ed -- I wasn't able to use small room at a USMC facility recently, in fact they required a base of 3.000 sf for a wet system. You are however allowed to discount for use of QR heads applied to that 3,000 sf.
