Thanks guys. This one was a borderline if I would do it or get a PE involved. The existing supply is 8" with pretty good pressure. The sprinklers are spaced around 110. 120 is allowed for Class IIIB. Branch lines will have to go, along with 1/2" sprinklers. There are 5 mains, not sure why, but it is old screwed schedule system, with a couple 6" Main Mains (not from chapter 3). I will pass on this one. The class and rack configurations were not so much a worry as the smaller containers piled everywhere. Kinda like seeing a Ford engine in a Chevy, just doesn't look right. Besides I think this will qualify for state requirement of professional.

They really need to get an FPE involved who has worked with this type of occupancy to figure out storage arrangements and come up with criteria. Assume that the existing piping will have to be ripped out and replaced with new. Hopefully the underground is at least 6". Also get a new flow test. That could be critical on how you proceed.
