As the owner for a building designed to have metal plate wood trusses, what documentation should I receive to be assured that the manufactured wood trusses delivered to the site have indeed been manufactured at a licensed and registered wood truss manufacturer under the required written quality control procedures?
The documentation you should receive to be assured that the trusses are designed, manufactured, and delivered in accordance with the Truss Plate Institute's ANSI/TPI 1 is the truss design drawings.
Truss design drawings are the graphic depiction of an individual truss. The truss manufacturer is responsible for manufacturing the trusses in accordance with the final approved truss design drawings using exact quality criteria established in the Truss Plate Institute's ANSI/TPI 1. Although the primary use of truss design drawings is to aid in the manufacture of trusses, they are a valuable resource for anyone building with or inspecting trusses.
