Acquisition and processing of input data for an object: oriented safety risk simulation in building construction

The construction industry records the highest rate of accidents amongst all industrial sectors. Accidents occur due to shortcomings in the identification of unsafe conditions before an activity is executed. Building Information Modeling (BIM) is a promising development in the construction industry, which can be applied to considerations relating to occupational health and safety issues. Only a few research activities have earlier focused on the use of BIM to identify safety hazards. The present work deals with the integration of the processes of risk assessment in a model-based environment. Based on algorithms that have been developed, a systematic identification and categorization of hazards - based on a building model - has been devised. The hazards are specifically identified with regard to object, process, and environment, and documented in the context of an object-oriented database. This paper will show the process of input data acquisition for generating the knowledge base.
