A project we had a few years ago entailed sprinkling below a deck at a local Sports Bar. The construction was pressure treated wood, ranging from 2ft to about 4.5ft above asphalt pavement. The local Fire Marshal required the sprinklers below because he said that there could be trash accumulation below the deck and people smoking on the deck who could drop a cigarette through the deck igniting the trash.
But for a school, what is the purpose of the deck and what are the physical arrangement of it, i.e.: how high off the ground, if elevated is there any traffic passing under it or could it be used for storage of things like lawn equipment or such?

No storage. No overhangs. The building is one story, with a crawlspace. The area below the crawlspace (which is the rest of the underneath) is open to the outdoors, and open to the area under the deck. For now disregard this area. Say this building is on grade and only the deck is on piles. Similar to a deck in a typical house. No storage below the deck. Would that space have to be sprinklered? Any code to justify the answer? In your reply, you say "we sprinklered that". Is "that" the overhangs or the space below the deck, or both.

Any storage or other use? If the school is on pilings, what about the rest of the "underneath"? I had a similar situation, but with a building overhang and we sprinklered that; I would assume this would need to be also.
