UAS-BIM based Real-time Hazard Identification and Safety Monitoring of Construction Projects

Abstract

The construction site is a dangerous workplace. The risk of fatality, injury, and property damage is significantly higher in construction jobsites compared with workplaces in other industries. Hazardous accidents happen due to traditional safety planning or failure to monitor the construction safety rules during a construction process. Recently, variety of approaches and technologies have been developed to achieve benefits in design-for-safety or safety performance. Unmanned Aerial System (UAS) technologies can easily monitor all over the site by flying around the construction site under a safety manager's control and transmit real-time information for inspecting safety purposes among the project. This paper presents a safety monitoring framework in the construction projects. The framework consists four following processes; BIM based Model, Safety Regulations, UAS-based collection of Safety Inspection Dynamic Data and Analysis of Project Safety. This system has a potential to assist designers, workers, and safety managers to mitigate construction accidents and fatalities. Throughout the design stage, this system with the help of 3D software and BIM is capable of identifying potential hazards. It also will make use of the gathered information to prevent the potential hazards. In control phase, the UAS gives possibility of these rules' monitoring and control. This novel method integrates BIM and UASs, and allows the potential users such as safety managers to obtain and analyse data in construction sites, which in turn can enable safety specialists (supervisors, agents, and inspectors) to identify hazards at different project phases and develop suitable mitigation strategies. The integration of 4D BIM-based models and UAS technology have the potential to improve identification, implementation and monitoring of construction site safety and hence increase the construction projects stakeholders' safety.
