Development and Application of Smart Construction Objects and Management System for an Efficient and Cost-Effective Safety Management

In this study, five Smart Construction Objects (SCOs) are developed and demonstrated. The usefulness and characteristics of the developed SCOs were evaluated using a tri-axial diagram analysis method. In addition, a smart construction management system associated with the developed SCOs is proposed. The efficacy of the management system is demonstrated by applying it to various types of construction site, including tunnel construction, railway construction, and underground water tank construction. The results of the tri-axial diagram analysis showed that the developed SCOs have improved awareness and autonomy compared to previously available ones. Multiple on-site applications of the developed smart construction management system resulted in a significant reduction in the time and cost required for construction by more than 40% and 70%, respectively, compared to conventional methods. This is attributable to the simplification of construction resource management procedures, JSA (Job Security Analysis), TBM (Tool Box Meeting), PTW (Permit to Work), and nonconformity management.
