This paper presents an innovative approach to real-time monitoring in construction management by integrating Building Information Modeling (BIM) with edge computing to develop a hybrid system. The study explores how this proposed system addresses the critical demand for immediate data access and rapid response, overcoming the limitations of traditional standalone and client–server systems in dynamic construction environments. The research follows the development and performance assessment of a prototype through a case study focused on site safety monitoring. The prototype utilizes ultra-wideband (UWB) sensor technology for precise worker tracking and alerting within hazard zones, offering significant improvements in time latency compared to conventional systems. Results indicate that the hybrid system substantially reduces the response time to potential hazards, enhancing safety measures. The hybrid system’s architecture also allows for standardized and flexible data management with BIM, facilitating the expansion of applications without complex modifications to server architecture. Through rigorous experimentation, the study demonstrates the hybrid system’s superior performance with the ability to issue alerts more rapidly and reliably than client–server models. The research underscores the potential of this hybrid approach to advance real-time monitoring in construction, promising benefits for safety, efficiency, and management, while also acknowledging the limitations of hardware capabilities and real-world construction conditions.
