The main objective of this research was to develop a BIM-based workflow how changing information can be handled in the O&M phase. The core of this lies mostly in the use of the Semantic Web standard to connect the BIM to external data sets, and subsequently the ability to alter the properties of elements. This ensures that the information is always up-to-date. The addition of a single triple indicates the timeliness of this information. The usage of Semantic Web technologies enables this improvement, as data elements are made available as unique identifiers which can be addressed and accessed by the application. This way knowledge about elements in a building can be captured in an easy and retraceable way.
The improvement that has been demonstrated in this thesis lies in the use of BIM in combination with the Semantic Web standard in the visualisation and connection of data with 3D models and the security that data is up-to-date. In addition, this way the history of objects in a building can be inspected at all times. Here lies a big opportunity for the construction sector to improve information management in the exploitation phase.
