I believe this is the reason you can lookup in wally world and see branchlines every so often that have short armovers w/ uprights. I was curious until your question and now I'm going to look to verify. I wonder if you aren't working on the same company's stores that we are All of our hanger details are general for all trades but specific at the same time. Our S-T is in TN and I believe most GC don't enforce the whole branhline hanger due to factoring in common sense vs. type.

The problem is that the Mechanical Engineer used a generic spec and details for all trades. His response was that the contract drawings show this because the joist manufacture will void the warranty if we hang further than 6" from the panel points. We have approved plans from the Architect and Engineers showing the branch lines hung from the top cord and not the panel points of the top cord so we will ask for a change order. We also have a phone conversation report showing that the Structural Engineer had no issue with our branch line hanger detail. The lesson for us is to exclude this in our bids. Matt -----Original Message----- Actually, right now I'm designing a very similar store and in the specs and details it says the same thing in reference to all piping. We have installed many and they have never enforced the branch line piping. However I have noticed in some stores Like Wally world the branchlines are run at those locations and where the head spacing did not work out they had short armovers for those particular uprights. Bad thing is I'm having a time just getting bottom chord sizing for bar joist and girders, I can only imagine trying to get webbing layouts. I'm interested to know how it turns out. Good luck.
