Abstract:  With the rapid advancement of technology in the construction industry , smart construetion siteshave become a key trend. This paper uses the Decision Making Trial and Evaluation Laboratory ( DEMA-TEL) method to analyze the eritical elements of safety management on smart construction sites, aiming toimprove the elliciency and elfectiveness of safety management. Through a combination of case studies.expert interviews, and literature review, this study develops a comprehensive system of factors covering e-quipment, process management, personnel, and the site environment. The DEMATEL. method is thenapplied to highlight the importanee and interrelationships of these elements. The findings indicate thattechnological innovation , personnel training, supervisory mechanisms, and environmental adaptability areessential strategies for improving the ellectiveness of salety management on smart consruction sites. Theimplementation of these strategies significantly enhanees the quality of technology application and person-nel training, optimizes supervisory mechanisms, and strengthens environmental adaptability. The resultsof this study provide valuable theoretical support and praetical guidance for the construction industry inimplementing safety management strategies for smart construction sites, helping to drive safety manage-ment toward greater effcieney and systematization.
