be when choosing this method.

When applying the 3000 sf design area required for unsprinklered combustible
concealed spaces, can the area be smaller than 30
Does the NFPA 13 definition of 'non-combustible' apply?

When applying the 3000 sf design area required for unsprinklered combustible
concealed spaces, can the area be smaller than 3000 sf based on the
surrounding walls and ceiling assemblies all being one hour fire rated? In
this situation I have rooms that are separated from the other areas
. Floors 3 thru 12 assuming LH could be designed to 1500 sf or less if
the QR criteria were met.
For the office in a warehouse, the office itself and the ceiling/roof
system above the office would require a 3000 sf design area, if the CC
space is in the ceiling of the office. If the CC space

I've got a NFPFA 13 ('02) project that requires a 3,000 sf design area due
to nonsprinklered combustible concealed spaces (TJI construction).
The upper floor consist of dwelling units with residential sprinklers and a
central common area with QR sprinklers.
The total area protected by the QR

attic heads.
