This study analyzed the major change of revised Construction Technology Promotion Act in the field of safety management. In order to increase the execution of the system of construction safety management, Construction Technology Promotion Act was revised at the end of 2018. The key issues were founded in the system of safety management plan, regular safety inspection by external professional organization, and irregular safety inspection by clients. By revised law, the role and responsibility of construction clients was enforced and the clients were recognized as leading participants in construction safety management.

According to the announcement of revised Occupational Safety Health Act(February 9, 2018), the construction client should make or manage the three S&H files in the plan, design, and work stages respectively.
