In recent years, while efforts for work style reform are being called for, remote work is becoming common in addition to improvements in work efficiency and workload reductions. For scheduled inspections at nuclear power plants, we have developed a "3D as-built management system" that can also contribute to work style reform, because it reduces the number of preliminary visits to the worksite before actual inspection/maintenance work takes place by visualizing the layout and arrangement of plant facilities using a 3D laser scanner. This report presents the system and the resulting effects and describes its applications to improve the efficiency of maintenance work.
