The Improvement Priority of Inhibitory Factor for Invigorating the Modular Building : Focused on Professional of Work Related to Modular Building

Abstract

Purpose: Recently, there has been a gradual rise in interest for modular building due to its advantages of shortened construction periods, quick removal, and practical use of land. However, widespread interest has yet to present itself in the markets and actual cases of construction based on modular building has been limited to military barracks, dormitory facilities, and single housing units. In light of this, this research aims to uncover factors that will encourage greater utilization of modular building and rank such factors according to their improvement priorities. Method: The method of research of this study first involved the uncovering of factors that discourage modular building through analysis of previous research and consultation with experts. Second, expert surveys were conducted for the purpose of improving the uncovered factors that discourage modular building. Third, based on the findings of the surveys, IPA analysis was carried out to establish the improvement priority rankings of the inhibitory factors. Results: The results of the analysis indicated that the encouraging factors were concentrated in the planning and ordering phase as well as the production and manufacturing phase. Rather than focusing on the dismantling and reuse of modular building, it was found that market entry and development of housing technologies were more immediately needed. Also in order to encourage the utilization of modular building, greater efforts by relevant personnel as well as continued studies by researchers are needed.
