Practice field fire sprinkler design
Type IV-Membrane-covered structures in which the frame is made from heavy timber and the membrane is noncombustible or flame resistant. Type IIB-Membrane structures in which the membrane is noncombustible as defined by Section 703.4 or membrane-covered structures in which the frame or cable is noncombustible and the membrane is either noncombustible or flame resistant. Fire safety of such structures and the premises is regulated by the International Fire Code® (IFC®).īecause of the limited fire-resistance capabilities of the membrane, membrane structures are usually classified as Type IIB, IV or V. So that a membrane structure will continue to provide its intended function, it must undergo continuous maintenance.
PRACTICE FIELD FIRE SPRINKLER DESIGN CODE
Otherwise, the other applicable sections of the code apply. This section includes provisions for construction types, height and area limitations and structural support. Looks like you are headed in correct direction, seems they have to stick to the limits of the code!? Not an engineer, but saw the circus last night under the big tent, I really just want to get over the area hump right now, and don't want to deal with questions of possible future occupancies like concerts and graduations. If there's a better answer in the IBC than the place I've arrived at, please let me know. The question is then where do I require sprinklers in this building? In any storage rooms? Over the single bleacher? This would allow them to not sprinkler the field(s). If they add seating, it looks like I can call it an A-4 and apply 507.3, exception 2 for unlimited area. If this is a practice facility with no bleachers, can it be an A-4? Section 303 states an A-4 is indoor sports with spectator seating. That's not even close to soccer field size. If it's an A-3 and can't be unlimited area, Table 503 and 506.2 give me 16,625 sf with a fully open perimeter. I assume you can't support sprinkler piping from an air-supported structure.
PRACTICE FIELD FIRE SPRINKLER DESIGN HOW TO
If this is an A-3, I don't see how to get it into the unlimited area section (507.6) without sprinklers. How do large air-supported structures fit into the 2009 IBC? 3102.3 is telling me to call it IIB construction.
