Intelligent BIM-Based Monitoring of Construction Tower Cranes

With China’s economy, the construction industry has become an essential industry supporting the national economy. During the process of such industry’s development, the construction safety issues have always been a heated topic for researchers and media due to tremendous safety accidents caused by various factors, including Human errors, mechanical failures, environmental factors. These accidents cause not only tremendous economic loss but also citizens’ properties and lives. According to the survey, the probability of accidents caused by tower cranes was up to 57%. To improve and guarantee the safety of public interests and lives and the efficiency of construction projects. The tower crane group planning arrangement is unreasonable, resulting in the collision; construction personnel lack of appropriate technical certificates, construction experience, resulting in operational errors; tower crane is not scheduled for maintenance, mechanical parts of the ageing and rust, resulting in mechanical fall and tower collapse; due to extreme weather, such as high temperature, wind, snow, etc., resulting in the construction process of the tower crane overturned, etc. are now tower crane construction safety monitoring the urgent need to address the difficulties. In order to adapt to the development of the times and realize the intelligent transformation of the industry, the use of Building Information Modelling (BIM) technology for the surveillance of construction tower cranes is an extremely important development direction for future construction safety monitoring. Through IOT technology, cloud platform technology, the construction real-time information collected by the tower crane’s sensors is synchronized with the BIM model to realize the visualization of construction safety information. In contrast, through the real-time calculation of the cloud platform, the construction hazards are safely identified, and timely warnings are issued to avoid tower crane safety accidents.
