Metro Construction Personnel Safety Management System Based on BIM Technology and Smart Construction site Concept

Abstract

[Objective] Unsafe behaviors among personnel are significant factors contributing to safety accidents in rail transit engineering. To address the existing issues of video image monitoring systems, such as reliance on manual identification, delayed detection of safety problems, and inadequate real-time alarms, research on metro construction personnel safety management system is required. [Method] The construction scheme of the metro construction personnel safety management system is elaborated from the aspects of overall architecture, equipment installation for data collection modules, establishment of BIM (building information modeling), and software platform. The application of the above management system in specific engineering pilot projects is analyzed to verify the intelligent identification accuracy of the system. [Result & Conclusion] The application of the system on construction sites demonstrates that the system can intelligently identify unsafe behaviors of construction personnel, such as not wearing safety helmets, unauthorized entry into restricted areas, and sleeping or leaving posts, for which scenarios the accurately triggered alarms take up to 98%, significantly enhancing the precision and efficiency of identifying safety hazards. Relevant personnel can access surveillance videos in real-time through interactive terminals, receive alarm information promptly, swiftly locate the occurrence of hazards, and take necessary actions.
