The sprinkler main riser penetrates a continuous concrete footing per the foundation plan, featuring a cold joint and a sonotube sleeve creating a two-inch minimum clearance all around unnoted. A concrete fill of the same width as the footing surrounds the riser, with a minimum dimension of nine inches from the face and vertical depth ranges specified between one-foot-six-inches minimum and three-feet maximum to be verified in the field or with fire sprinkler drawings. Precast panels intersect above with pour strips and reinforcing bars including two number five bars by four-feet-long.
