Sealed Truss Placement Diagrams Revisited

  • Truss placement diagrams (TPD) are intended to assist in positioning trusses and related components supplied by the component manufacturer. 
  • On residential projects, the truss design engineer is responsible for the single truss design depicted on each truss design drawing. 
  • Since the TPD is not typically prepared under the truss designer engineer’s supervision, it is not considered an engineered document. 
  • It is not legal in most states for a truss design engineer to seal a non-registered person’s work for which he has no direct supervision.
