Thanks ken, I've read the chapter. But this is the architect/engineer from hell. He has disapproved every submittal from every trade several times over, causing extreme delays, and everyone is banging their head against the wall. He wants proof, and I'm not sure how to go about figuring out an equation.

Dry Va., then proceed back up to 28' AFF to feed a dry system. On the 4x 1'-0" arm-over we installed a pipe stand. (the arm-over is 5-0 above the floor) We also use clamps to support the drops to the walls. The engineer is asking for proof that the pipe stand can support the load. This is install and hasn't fallen is not enough proof. Anyone have a way this can be done? Dennis Wilson Blackhawk Auto.
