Embracing Innovation: The Rise of Mass Timber

Mass timber, once relegated to the realm of traditional building materials, is experiencing a resurgence in modern architecture. Innovations in structural timber design have paved the way for groundbreaking projects that challenge conventional norms, from bridges to skyscrapers. Crucially, these projects are not just pushing boundaries; they are also navigating building codes with ease, debunking the myth of code exceptions.

Breaking Records, Not Rules

One notable example is the T3 (Timber, Transit, Technology) mass-timber structure in Minneapolis, completed in 2016 by MGA | Michael Green Architecture and DLR Group. This seven-story, 224,000 square-foot commercial development defies expectations by offering expansive open floorplates, all while constructed with prefabricated nail-laminated timber (NLT) panels and glulam structure. Despite its size, T3 Minneapolis was erected in just 9.5 weeks and boasts a significantly reduced carbon footprint compared to traditional materials.

Expanding Horizons

Following the success of T3 Minneapolis, similar projects have emerged, including T3 West Midtown in Atlanta and T3 Goose Island in Chicago. T3 West Midtown, a seven-story, 230,000 square-foot office development, seamlessly blends historic timber elements with modern amenities. Meanwhile, T3 Goose Island is set to become the largest modern mass timber structure in the United States upon completion.

Code Compliance

Remarkably, none of these projects required code exemptions. Instead, they adhered to building regulations for Type IV heavy timber construction. According to DLR Group Principal Steve Cavanaugh, building code officials were receptive to mass timber construction, signaling a promising future for the industry.

Looking Ahead

The International Code Council (ICC) has recognized the benefits of wood construction, incorporating emerging technologies into the building code. The 2021 International Building Code (IBC) will introduce new construction types tailored to mass timber, accommodating structures of up to 18 stories with gypsum-covered mass timber elements.

Leveraging Research

Architects, engineers, and industry professionals can access valuable resources from the Think Wood Research Library, offering insights into seismic performance, fire safety, energy efficiency, and more. By leveraging research and embracing innovation, the mass timber industry is poised for continued growth and evolution in the years to come.
