This presentation will introduce learners to new Mass Timber buildings (Construction Types IV-A, IV-B, and IV-C). The criteria and products commonly associated with Mass Timber buildings will be discussed. The course will provide an overview of the work of the International Code Council’s (ICC) Tall Wood Building Ad Hoc Committee (TWBAH). The presentation will provide an overview of fire tests performed in support of these changes. Allowable heights and maximum number of stories permitted for the new Mass Timber Construction Types will be discussed, along with the basis for determining required fire resistance, and the importance of non-combustible protection.

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

• Examine the differences between Type IV-HT and the newer Construction Types, IV-A, IV-B, and IV-C.
  
• Describe the work of the ICC’s Tall Wood Building Ad Hoc Committee (TWBAH) leading to introduction of new Mass Timber Construction Types in the IBC.
  
• Summarize allowable building heights and areas permitted with the newer Mass Timber Construction Types, IV-A, IV-B, and IV-C.
  
• Review non-combustible protection and fire resistance ratings for each Mass Timber Construction Type and where exposed wood is permitted.
