Dump Trucks Columbus OH Insight:
When new tall-building, mass timber-related regulations become part of the next edition of the International Building Code in 2021, more cities will likely see an uptick in the number of developers seeking approval for mass timber structures, as long as local building departments adopt those provisions.
Among the new IBC code changes is the creation of three new types of construction:
- Type IV-A – maximum 18 stories, with gypsum wallboard on all mass timber elements.
- Type IV-B – maximum 12 stories, limited area of exposed mass timber walls and ceilings allowed.
- Type IV-C – maximum 9 stories, all exposed mass timber designed for two-hour fire resistance.
Ascent's 16-story mass timber system topping a concrete base falls under the first category and was engineered by Thornton Tomasetti.
Oregon was the first state to incorporate tall mass timber construction into its building codes and allows wood buildings taller than six stories without a special review process.
There are still those critical of using mass timber for tall buildings, however. A Portland Cement Association-sponsored survey of Americans found that 75% of 800 respondents were against raising the allowable height of wood buildings for various reasons, including that wood was not as strong as other materials and that it was a fire hazard.
