Leveraging Extended Reality technologies with RFID to enhance on field maintenance of buildings

The combined use of BIM and the advanced visualization provided by Extended Reality technologies can improve productivity in the project management processes in construction. This paper concerns an application of MR for seamless data retrieval from a BIM platform towards field workers in charge of maintenance. For instance, in case a failure of any systems has been claimed, workers must retrieve the information about the localization of components prior to repairing. This step can be facilitated by on field data visualization through MR. As the number of on field repair actions is huge in complex buildings, minimizing the time required for the alignment of virtual models is beneficial. Hence, an approach for model alignment that is based on the use of RFID tags has been developed. The first advantage is that these embedded devices are suitable for reuse at any survey with no need for re-deployment. Secondly, this approach does not require that the virtual model is displayed during the alignment, which makes it suitable for large models.
