Should my electrician drill holes for wiring through the truss members?

• Definitely NOT. Trusses are designed using the specific strength values of the various sizes of lumber and any holes reduce the strength of the truss. The only holes that should be drilled are for laminating multiple ply girders and to fasten bolted hangers. The details will be shown on the engineering page for the specific truss.

How important is bracing within the truss roof?

• Bracing is an integral part of the truss assembly and falls into 3 categories. Temporary bracing during assembly of the roof, permanent bracing of the complete roof structure and bracing of the individual truss members (webs, bottom cord and top cords). To see more detailed info on bracing see our Documentation section. All of which are very important! Temporary bracing adds safety at your job site. Permanent bracing is required. Your truss manufacturer should have given you a "job site" package when your order was delivered. This package contains a detail sheet containing the bracing requirement for the structure as a whole. Lastly, certain trusses with in the truss system may require additional support along the chords and or web members. You will need to review the Engineered sealed drawings for this information.
