Despite a slight decrease in the number of accidents at work on German construction sites, a large number of accidents on construction sites occurred as a result of the collision of different trades. An important potential is in the optimization of the safety and health by making available predefined information about work safety for all involved trades. The aim of the project is the application of the BIM-method and the use of RFID-technology and Augmented Reality to improve work safety in the real estate and construction industry. It has to identify, define, and standardize information relevant to work safety so that they can be used for prevention-measures with Building Information Modeling (BIM). To do so, a process map was developed to map all relevant occupational health and safety processes during the lifecycle phases of a building. Therefore, all work safety-relevant processes have to be identified and defined. Furthermore, a demonstrator was developed in order to show possibilities like the usage of Augmented Reality (AR) and a commercially available tablet with a web app, in combination with Bluetooth beacons and RFID technology, based on a common data base. This will lead to the possibility of cross-company planning regarding work safety-relevant processes with BIM as well as the optimization of work safety in additional use of AutoID-Technologies.
