Construction industry is extremely hazardous with construction workers almost three times more likely than average to suffer a fatal accident in the workplace. Although great improvement in safety performance has been noted, in recent years the improvement started stagnating. To tackle this issue and to improve safety on the construction sites, numerous Health and Safety (H&S) research is carried out. This research aims to contribute in reducing the number of accidents and consequently injuries by enabling automated hazard identification through the use of Building Information Modelling (BIM) and a specially developed construction hazards database. Goal of this paper is to present the structure and purpose of the database and how construction hazard and activity data was gathered and entered into the database. Sources for the construction hazard and activity identification process included scientific and professional construction H&S literature as well as specialised construction H&S documentation. Results presented in this paper are the first step of a research effort to enable automated identification of construction hazards through the use of BIM.
