At construction sites, work performed at heights under climbing conditions, often relying on climbing tools or facilities, is referred to as climbing work or working at heights. This type of work primarily involves ascending via ladders and performing high-altitude tasks during structural installation.

       This type of operation carries a relatively high risk of accidents. Therefore, when preparing construction organization designs, various climbing and elevation facilities required for construction should be considered and determined. Generally speaking, various climbing activities should make maximum use of existing conditions, such as utilizing building structures and access ladders on scaffolding, or vertical transportation equipment for personnel, such as construction elevators.
