Code officials vote to advance mass timber proposals

The International Code Council (ICC), the body that develops the model building codes widely adopted by governments, has undertaken a full review of the International Building Code (IBC) to ensure that building codes are up to date as more Tall Mass Timber Buildings (TMTB) are approved around the world.

In 2015, the ICC Board of Directors empaneled an “Ad Hoc Committee on Tall Wood Buildings” (AHC-TWB) to review the entire IBC for provisions that could be relevant to TMTB. Their mission was to investigate the science related to mass timber and to propose necessary code changes to ensure that mass timber buildings of greater height and area would have the strength and fire resistance required of all buildings to protect the public and fire responders. All buildings, regardless of material used, are required to comply with the fire resistance elements of the IBC.
