Abstract

Falls from heights make up the most dangerous risk factor in work accidents in the construction industry - the field with the highest fatality rate caused by work accidents in Israel, in the US and in many other countries. A large proportion of such accidents taking place on construction sites, especially those involving tall buildings, could have been prevented, with suitable protection. Due to the unique nature of such building projects, it is difficult to control these protective measures at all times, because of the physical structure of the building being erected. The present research has developed an automated model for management and monitoring of the risk of falls from heights in construction sites. The model identifies activities and areas of risk of falls from heights, in order to create a safety management system. The research methodology consists of: model development, as well as verification and testing via computerized implementation on an active building project. To demonstrate and verify the model, data from an active construction project was used to generate monitoring output. Experts analyzed this output and concluded that the model succeeded to identify the fall hazards and risk areas of falls from heights in the project, as well as dangerous activity needing guardrails or personal fall-arrest systems. The experts also emphasized that the model is an important and valuable tool in management of hazards and that they would use it on a regular basis to monitor the guardrail systems on sites under their management.
