A continuous improvement of safety performance is one of the desired goals of a successful construction organization. In order to improve the safety performance of construction projects, effective and corporative safety management program between head office and job site must be implemented. And its performance must be measured and analyzed for the identification of the problems in the safety management area. This study aims to analyze the safety management performance of domestic large construction firms. It is expected that the survey results can be utilized to establish the construction safety program effectively. The study performed questionnaire survey with 42 large construction firms. The criteria used in the Supermerit Certification System were chosen and examined by 9 industry experts.
