The building code does have some allowances for omitting sprinklers in
high ceilings for SPECIFIC uses. The ONE that comes to mind is atriums
but the area is restricted to low hazard contents (with an exception
when sprinklers are at the ceiling). I thought stadiums had a similar
allowance but could not quickly put my finger on it. Such things have
to blessed before hand so it comes down to what were you asked to bid
on? As Matt pointed out, if it says sprinkler per NFPA 13, there is
no such allowance for ceiling heights.

Subject: RE: Omitting sprinklers in a high building
Just saw this again today.
NFPA 13-2010 A.8.1.1 This standard contemplates full sprinkler
protection for all areas including walk-in coolers, freezers, bank
vaults, and similar areas. Other NFPA standards that mandate
sprinkler installation might not require sprinklers in certain
areas. Based upon experience and testing, sprinklers have been found
to be effective and necessary at heights in excess of 50 ft (15.2
m). For a building to meet the intended level of protection afforded
by NFPA 13, sprinklers must not be omitted from such high ceiling
spaces.
The requirements of this standard should be used insofar as they are
applicable. The authority having jurisdiction should be consulted in
each case. A building is considered sprinklered throughout when
protected in accordance with the requirements of this standard.

Subject: Omitting sprinklers in a high building
Is there anywhere in NFPA 13 stating that you can omit sprinklers if
the roof structure is above a certain height above the ground?
We have a manufacturing building that will have a 119ft deck and my
competition is stating that sprinklers would not be required.
Thanks,
Dewayne
