Truss Calc Package
Truss Calc Package
(OP)
I locations I have worked in the past the contractors would take our drawings, get a truss package, and send it to us. The only exception is if it was a complex layout and we wanted to get input from a truss manufacturer early on. We are working in a new area and we have worked with a few people that seem to think that it is our responsibility to handle all of that. What do you folks consider the norm?





RE: Truss Calc Package
Before, did you do any layout work and figure the girders or just put: "Truss design by Mfg." on the drawings and provide no real direction?
Residential or commercial?

We always lay them out to the best of our ability and calc girder reactions etc. When we have a complex roof we like to send over our layout early and get comments from the manufacture.
Residential. We did a previous job with this contractor in particular and he had no problem obtaining the truss package in a commercial building that used open web metal joists.
RE: Truss Calc Package
The SD should reflect your layouts or they are deviated from the CD's and are taking responsibility for building designs or at least messing them up. I usually give a lot of information regarding truss locations, loading, orientation and profile if it is not obvious. It really shouldn't matter if res. or comm. but usually a residential project is treated with a very poor procedure. Most houses are never designed by a DP and there are no layouts until the truss company makes one. I consider myself lucky if I even get the shops to review on a residential project (probably 10% come back for review). I do see a lot of drawings by DP's who don't even put the basics on the drawings for a truss designer. The manufacturers are just so used to running with it no matter how little info they get.
