| In recent years, various disasters have frequently occurred in Japan. Recovery construction work post-disaster often takes place in areas at risk of secondary disasters. Hence, "unmanned construction," a method uniquely developed in Japan, employs remotely operated construction machinery, allowing operators to work from a safe distance. However, it is said that unmanned construction is less efficient compared to conventional methods. To promote the adoption of unmanned construction and complete disaster recovery work safely and swiftly, it is essential to improve construction productivity. For the advancement of research and development aimed at improving construction productivity, it is crucial to clearly identify the causes of efficiency reduction in unmanned construction and focus resources on research and development to address these causes. However, no study has quantitatively verified these causes to date. Therefore, this study aims to identify the causes of reduced efficiency during unmanned construction by conducting experiments using actual remotely operated construction machinery. |
