With encouragement from the U.S. wood products industry, in 2016, the International Code Council (ICC) formally began to explore the feasibility of adding provisions for tall mass timber buildings in the U.S. model building codes.  Since that time, the ICC Tall Wood Building (TWB) Ad Hoc Committee has reviewed voluminous materials regarding tall mass timber buildings, including domestic and international research.  The TWB developed a comprehensive set of technically substantiated code changes, supported by a number of unique fire testing scenarios and designer input.  These code changes, including provisions for permissible building heights and areas, number of stories, and fire requirements, were approved by the ICC membership and are now part of the 2021 International Building Code (IBC).  A subsequent proposal to modify the code-specified limits of exposed mass timber on the ceiling was approved in 2021, and will be part of the 2024 IBC. This presentation will provide a brief oversight of the new U.S. model code provisions for Tall Wood Buildings and the adoption of these provisions throughout the U.S. 

By the end of this course, you should be able to do the following:

  • Identify applicable standards used in qualification and performance evaluation of mass timber products. 
  • Recognize US model building code provisions for mass timber construction. 
  • Differentiate which design standards and material standards are referenced within US model building codes for the purpose of mass timber design. 
  • Examine the various processes by which code provisions are adopted and the current status of adoption of mass timber code provisions throughout the US.
