Webinar – Mass Timber Hybrid Systems: Combining Structural Materials to Maximize Efficiency

March 10, 2021 – 12:00 pm - 1:00 pm




Join at 10 am Pacific, 11 am Mountain, 12 pm Central, 1 pm Eastern

Modern timber buildings typically include a combination of wood and other materials, with light wood framing, steel and concrete utilized where structurally efficient. However, successfully realizing a hybrid of mass timber and other materials requires an acute understanding of their differences, from fabrication tolerances to installation techniques, and connection details. In this presentation, two hybrid projects will be presented to illustrate these key design and construction considerations. The Condos at Lost Rabbit in Mississippi utilized what is seemingly the best of both worlds—mass timber floor systems that provide inherent beauty, fire resistance and thin floor structures, paired with light wood-frame bearing walls that can be used to run MEP services while meeting code requirements for acoustics and fire resistance when clad with materials such as gypsum. 901 E 6th in Austin is a unique 5-story project—and the first in Austin to include cross-laminated timber (CLT). By leveraging the respective capabilities of structural steel framing and CLT floor panels, this 129,444-sf office building was able to achieve highly-efficient floor plates, 14-ft floor-to-ceiling heights, and large windows. Hear firsthand from the design and development teams of these projects, as they discuss their reasons for using mass timber and lessons learned from the hybrid approach.
