| description abstract | Mass timber is a promising building material that has been used in Europe for a long time. Structural rigidity, renewable characteristics, and low-carbon footprint have made this material a major structural component in the European construction market. While the concept of mass timber building has been successful in Europe, the US construction practitioners are still dubious to adopt this material on a greater scale. In the US construction industry, mass timber has received very little consideration from the stakeholders. Lack of case study projects, awareness, and work experience in mass timber materials have created an industrywide knowledge gap that is hindering the progress of this innovative building material in the US construction market. This study evaluates the feasibility of mass timber products in the US construction industry by analyzing its level of awareness, existing challenges and difficulties, and recommendations to improve the existing perceptions to help solve the knowledge gap and increase the current acceptability of mass timber products among the US construction practitioners. The research method includes three different sets of semistructured questionnaire surveys, distributed among 1,200 construction companies, 300 architectural firms, and 55 mass timber manufacturers in the US. Data analysis of the surveys suggested that the US construction practitioners have significantly low involvement level and work experience in timber building design and construction. The main perceived benefits of using mass timber material are the requirement of a small workforce during construction, aesthetic appeal, and prefabricated characteristics of timber panels. Major perceived downsides are lack of work experience, insufficient timber manufacturing plants, high cost of engineered wood products, and code limitations. Several recommendations were provided on the survey including from the study such as increasing awareness among the stakeholders by undertaking more timber building projects, establishing more manufacturing facilities, developing codes and standards, and developing a skilled workforce experienced in timber construction. The outcomes of the study will be a helpful reference source for US construction practitioners to evaluate the actual feasibility of mass timber as a building material. It will further help increase the acceptability of mass timber products in the US. | |
