A framework for 3D-model based job hazard analysis

The accident rate in the construction industry is the highest rate among all industries. In most cases, safety-planning is based on checklists and manual description which are not closely related to the actual and specific construction object. Safety planning in construction is a challenging task because of the large number of parties involved, the constantly changing conditions and the complexity of buildings. The objective evaluation of safety-planning methods regarding qualitative and quantitative factors could be considerably improved by applying innovative and integrated safety-planning tools. Modern technologies, such as Building Information Modeling (BIM), are offering an object-orientated planning approach towards the project's lifecycle. This paper solves this problem by applying an object-orientated and process- orientated job hazard analysis based on Building Information Models (BIM). The proposed rule-based system can detect a safety hazard early on in the design and planning process.
