Meeting Title: 

Design and Construction Using Cross Laminated Timber


Aceh Community Room

Ethan Martin, WoodWorks


Cross laminated timber (CLT) is an engineered wood building system designed to complement light- and heavy-timber framing options. Now available to North American building designers, it offers the structural simplicity needed for cost-effective projects, as well as benefits such as fast installation, reduced waste, improved thermal performance and design versatility. This presentation will introduce CLT through a series of project examples while considering some of the more challenging aspects of CLT building design—such as fire and life safety, lateral and seismic design, acoustic performance and building envelope. Topics will also include the manufacturing and specification of CLT, building code considerations and available resources such as the US CLT Handbook.

As the Northwest Regional Director for the U.S. WoodWorks program, Ethan’s directive is providing project assistance, education, and resources for developers, architects, engineers, and contractors for code-compliant design, engineering, and construction of non-residential and multi-family wood buildings. Ethan is a licensed engineer and joined WoodWorks when the pilot program went nationwide in 2011. Prior to that Ethan had his own engineering firm for eight years and is a Civil and Environmental Engineering graduate of Cornell University specializing in structures.

WoodWorks is a non-profit organization established and led by the Wood Products Council and funded by the Softwood Lumber Board, USDA Forest Service, Forestry Innovation Investment and Natural Resources Canada and is closely affiliated with the American Wood Council and other partner organizations, whose resources it utilizes in the resolution of technical issues and the identification of appropriate wood solutions.
