Abstract/Summary
Mass timber is a relatively new construction building material consisting of large-scale engineered wood products such as cross-laminated timber (CLT) and glue-laminated timber (glulam). It is gaining attention as a sustainable alternative to traditional steel and concrete, offering benefits such as reduced carbon emissions and enhanced aesthetic appeal. Despite being used on notable projects recently, it is not yet widely accepted by the industry as a whole. This study investigates the evolving awareness, benefits, and challenges associated with mass timber construction among U.S. construction professionals. Through a survey of over 100 construction practitioners, primarily from Cal Poly’s Construction Management Advisory Council (CMAC) in California, this study provides updated insights on industry perceptions, particularly in comparison to Ahmed’s 2022 research on mass timber awareness. It was revealed that while both cost and experience remained as large challenges; 30% more respondents stated that material protection was a concern when working with mass timber. Additionally, 22% more respondents have had 1-5 years of experience working with mass timber. This indicates that as constructors gained more experience, the challenges have changed. This study allows the industry to identify current challenges and perceptions regarding mass timber, thus effectively able to adapt and change accordingly.
