3 Course&DescripPon& Mass timber represents a rapidly advancing technology that can be utilized as an alternative to steel and concrete to frame a variety of mid- and high-rise building types. This presentation provides an overview of available mass timber systems, with an emphasis on their advantages and unique design considerations. Topics will include connections and fasteners, which differ from those used in light-frame wood construction, including available options and code requirements. Practical design considerations with regard to project location, climate, material sourcing, weather and fire protection, as well as detailing for dimensional variability, will also be reviewed. Cost estimating will be discussed, as successful mass timber projects require a complete understanding of both the system itself and impact on trades.&
