Building Information Modeling (BIM) and Safety: Automatic Safety Checking of Construction Models and Schedules

Construction safety is a national and worldwide issue. This paper contributes in solving this problem by applying automated safety rule checking to Building Information Models (BIM). Algorithms that automatically analyze a building model to detect safety hazards and suggest preventive measures to users are developed for different cases involving fall related hazards. As BIM is changing the way construction can be approached, the presented work and case studies extend BIM to include automated hazard identification and correction during construction planning and in certain cases, during design. A rule-based engine that utilizes this framework is implemented on top of a commercially available BIM platform to show the feasibility of the approach. As a result, the developed automated safety checking platform informs construction engineers and managers by reporting, why, where, when, and what safety measures are needed for preventing fall-related accidents before construction starts. The safety area reviewed is fall protection. An example case study of such a system is also provided.
