Neil: I appreciate your comments regarding prefabricated trusses. For these very reasons I am reluctant to specify gang-nail pre-fabricated wood trusses. In the event of litigation it is fairly easy for attorneys to find fault in anyone remotely involved with the project team whether or not there is actual negligence. Before I was self employed I was once involved in such a case where I was asked to inventory the grade stamps on all chord and web members in an attic and it was not surprising to find lower grade members than specified on the shop drawings, trivial yet ammunition for the case. Several years ago I designed roof framing for a low income family project and I specifically avoided pre fab trusses but was forced to make revisions ( at gun point) at the last moment to save money. Sure enough I ran into the same issues you described. The contractors were stunned when I required lateral bracing and deflection spaces at partition walls. Have you ever tried to read the truss manufacturers fine print on the back of a shop drawing....sheesh! Regards, Jeff Smith.
