The following article provides SBCA's proposed best practice Truss Design Drawing (TDD) warning note language for CMs to use as a standardize approach with respect to defining their scope of work. 

Proposed Sample TDD Warning Note Language

WARNING.  The design assumptions, loading conditions, suitability and use of the Trusses depicted shall be verified by both the Contractor and Building Designer. The approval of the Truss Submittal Package, including the Truss Design Drawings (“TDDs”) and Truss Placement Diagrams (“TPDs”) is the responsibility of the Building Designer and Contractor. All notes and instructions set out in the TDDs, TPDs, any TDD Cover Sheet and documents referencing the TDD shall be reviewed by the Building Designer. Upon transmittal of the Truss Submittal Package and upon delivery of the Trusses to the Contractor, the Contractor shall read all notes and instructions in the TDDs and TPDs and review the practices and guidelines of Building Component Safety Information (“BCSI”) and/or its summary sheets as published by the Truss Plate Institute and the Structural Building Component Association. Only metal connector plates manufactured by __________ [Plate Supplier] shall be used for this TDD to be valid. The TDD represents acceptance of responsibility for the design of only the single Truss depicted pursuant to ANSI/TPI 1, the National Design Standard for Metal Plate Connected Wood Truss Construction (“TPI-1”). Any field of use of the Truss, including handling, storage, installation and bracing, is the responsibility of the Building Designer and Contractor.
