1. Reason for Amendment
In order to enhance the safety of construction machinery, safety standards for pile drivers, pile extractors, and aerial work platforms for tunnels are introduced to prevent safety accidents. Furthermore, safety standards that do not conform to international standards are revised, while addressing and improving certain deficiencies identified in the operation of the current system.
