Assessing the Construction Safety Management System (CSMS) Implementation in the SAMSAT Samarinda City Office Building Project

The construction industry is widely recognized as one of the most hazardous sectors due to the complexity of activities, dynamic site conditions, and the use of heavy equipment and high-risk operations. To address these risks, the Indonesian government introduced the Construction Safety Management System (CSMS) to ensure systematic safety planning, risk control, and continuous safety improvement in construction projects. This study aims to evaluate the implementation of CSMS in the Office Building Construction Project of SAMSAT Samarinda City. The research adopts a qualitative descriptive case study approach using triangulated data collection methods, including field observations, document analysis, and semi-structured interviews with project management personnel and safety officers. The analysis focuses on five key dimensions of CSMS implementation: leadership and safety commitment, safety planning, safety resource support, construction safety operations, and safety performance evaluation. The results indicate that CSMS has been implemented in a structured and systematic manner, reflected in the establishment of a safety organizational structure, routine safety meetings, regular occupational health and safety inspections, and hazard identification and risk assessment for major construction activities. The project also recorded zero occupational accidents during the monitoring period from August to December 2025, indicating effective safety management practices. Overall, the implementation of CSMS in this project complies with applicable regulations and demonstrates good safety performance, although strengthening safety culture, consistency in supervision, and documentation practices remains necessary to further enhance the effectiveness of construction safety management.
