I am curious what the standard is for bracing design of pre-engineered trusses (wood or metal). Do you require that the truss supplier design and provide a stamped bracing plan?

The first is bracing required for the design of the individual components of the truss. These should absolutely be designed by the TRUSS DESIGNER.
The second type is for the bracing of the truss/roof system as a whole so they dont topple like a deck of cards. (Imagine wind load on the gable side of a truss) These probably are best designed by the building EOR, in my humble opinion. These should consist of vertical diagonal bracing within the webs of the trusses, and sometimes diagonal horizontal bracing along the bottom chord, depending on the particular situation. The TPI has good information on this.
