Enhancing Design and Construction Technology Education Through the Context of Mass Timber
Mass timber is an emerging construction technology growing in popularity in the United States. One obstacle in the gradual adoption of mass timber construction is the limited availability of qualified engineers and designers. This project aims to identify existing timber engineering courses and educational resources available to university students and instructors in the United States and identify areas for improvement to enhance the future engineering and construction workforce. Specifically through input from a panel of qualified industry professionals, a DACUM chart will be produced using the Delphi Survey Methodology to provide a unified series of tasks and duties that are viewed to be important for entry level structural engineers working in mass timber design. The results of this will provide clarity on curriculum needs to ensure graduating engineers are prepared to work with mass timber elements. Additionally, interviews will be conducted with university-level timber engineering instructors to discuss instructional materials that are currently available and determine what new educational resources are needed to help increase the availability of mass timber-related course taught nationwide. The results of the interviews and DACUM chart will guide the development of mass timber engineering educational materials, including learning modules, virtual tours, and student assignments that can be presented independently or implemented with existing engineering coursework.

Many transportation agencies allocate significant time and resources each year to remove ice and snow from their paved surfaces to achieve a safe, accessible, and operational transportation network. An electrically conductive concrete (ECON) heated pavement system (HPS) has been shown to be a promising alternative to conventional snow removal operations using snowplows and deicing chemicals, which is time-consuming, labor-intensive, and environmentally unfriendly. An ECON HPS utilizes the inherent electrical resistance of concrete to maintain the pavement surface at above-freezing temperatures and thus prevent snow and ice accumulation on the surface. Such a sustainable concrete pavement system improves its infrastructure resiliency by allowing it to be safe, open, and accessible during even harsh winter storms.
