AB  - Falls are among the most frequent and hazardous incidents in the construction industry, posing significant challenges due to their unpredictability and severe consequences. In addition to fall-related accidents, construction sites are subject to various safety hazards, underscoring the need for advanced technological solutions aligned with lean construction principles.  Traditionally, hazard zones are marked using analogue methods such as boundary tapes. However, this study explores the application of geofencing technology to enhance construction site safety by providing real-time warnings to workers approaching fall hazard areas. Specifically, this research integrates two innovative geofencing-based safety technologies: (1) a smartphone-based alert system for fall hazard zones and (2) a location-based final job risk assessment tailored to specific work areas.  The proposed geofencing system utilizes Closed Circuit TV (CCTV) footage to define fall hazard zones and work areas, automatically detecting worker entry and transmitting risk analysis data to their devices. By delivering real-time alerts and up-to-date risk assessments, this system contributes to lean construction objectives by minimizing delays, reducing risks, and empowering workers to make informed decisions - ultimately improving safety and efficiency on construction sites.
