The Truss Plate Institute (TPI) announced the opening of a Public Review & Comment period for the draft BSR/TPI 1-2022 (revision to ANSI/TPI 1-2014) National Design Standard for Metal Plate Connected Wood Truss Construction. The Public Review & Comment period is open until June 20, 2022.

TPI began the process of revising the current ANSI/TPI 1-2014 standard in December 2019 with the formation of a Project Committee representing a cross-section of the industry. This draft, now open for Public Review, is the culmination of their efforts. The proposed revisions presented in the BSR/TPI 1-2022 draft provide enhancements to ANSI/TPI 1-2014.   

Comments are being solicited to ensure that the views of all interested parties have been given full consideration. The draft BSR/TPI 1-2022 establishes minimum requirements for the design and construction of Metal Plate Connected wood trusses. The standard describes the materials used in a truss, both lumber and steel, and design procedures for truss members and joints. Responsibilities, methods for evaluating the metal connector plates and manufacturing quality assurance are also contained in the standard.  

Those wishing to participate in the Public Review of the draft BSR/TPI 1-2022 standard should visit TPI’s website ( ) or contact the Truss Plate Institute at (240) 587-5582.
