Exactly. The paragraph I mentioned (9.2.1.3) pertaining to the Building Structure in 13 has been used to make the sprinkler contractor hire a structural engineering firm to provide proof that we were in compliance with Chap 9 of Our standard. In Todd's situation.. the hanger has to meet 5 times plus 250. Since it is not listed under the section for Building Structure in 13, the 5 times does not need to be added, only the weight plus 250.
