The 2021 International Building Code allows for construction of tall mass timber buildings with larger heights and areas than previously permitted in Types III, IV, and V construction. This course will provide an overview of mass timber which includes any product currently permitted for use in Type IV (heavy timber) construction such as cross-laminated timber (CLT), structural composite lumber (SCL), glued laminated timber (glulam), mechanically laminated decking (aka nail-laminated timber, NLT), and large section sawn timbers. Learn about provisions first introduced in the 2015 and 2018 IBC for mass timber construction as well as an overview of tall mass timber construction per the 2021 IBC and 2021 International Fire Code. Research and development conducted in support of new tall mass timber Construction Types IV-A, IV-B and IV-C in the 2021 IBC will also be discussed. Topics include: heights and areas, fire safety, fire and connection design, construction fire safety, special inspection, energy, acoustics and lateral


  1. Recognize the unique fire resistive characteristics of mass timber as it influences the use of wood in building construction.

  2. Summarize new provisions in the 2021 IBC and IFC including those first established in the 2015 and 2018 IBC related to mass timber products and Type IV construction.

  3. Recognize how new types of construction compare with existing types of construction in the IBC and specify the inherent differences and conservative approaches for the new construction types.

  4. Evaluate the new provisions for heights and areas, fire safety, fire and connection design, construction fire safety, special inspection, energy, acoustics and lateral design provisions.
