Small and medium-sized construction projects account for the absolute majority of construction projects in Korea and contribute greatly to the national economic development. However, there is a lack of awareness of productivity in small and medium-sized projects, resulting in a number of economic losses or safety problems. Therefore, it is necessary to identify major factors and causes that hinder productivity during construction and to suggest measures to improve productivity. This study established a classification system for factors impeding productivity through systematic literature review and Focus group interview as preliminary investigation. Through a two rounds of Modified Delphi method, the lack of worker responsibility, irresponsible drawing plan that ignore site conditions and construction ability, excessive design changes, incorrect work plan, interference between tasks due to urgent works, lack of safety issues were chosen as major factors impeding productivity. As a result of conducting interviews with experts to derive the cause of the factors and improvement measures, it was found that insincere manpower and incorrect design and construction plan in the initial stage impeded productivity severe. Consequently, vocational education for workers, introduction of modified cost calculation methods for small and medium-sized construction, and the active introduction of smart technology need to be conducted to improve productivity in small and medium-sized construction projects. This provides a theoretical basis for future research on the productivity of small and medium-sized construction projects and suggests solutions to the future crisis facing small and medium-sized construction companies. |
