Expansion of IFC Data Model to Kinematic Sensor at IJUP2012 by Bruno Ferreira
The document discusses the expansion of the Industry Foundation Classes (IFC) data model to include kinematic sensors for structural health monitoring in buildings. It highlights the importance of integrating sensor data into Building Information Modeling (BIM) and emphasizes that while the IFC model supports interoperability, it requires further enhancements for specific use cases. The conclusions drawn suggest that robust models alone do not ensure successful information exchange within the construction industry.

- 15. Conclusions It ispossible and relevant the introduction of data information obtained from SHM into a BIM model, through the current IFC configuration; The definition of a robust model does not guarantee the success for the exchange of information on construction industry; The standard models should be complemented by partial models or extensions to the model itself, for more specific contexts;
- 16. Conclusions The IFCmodel is an adequate support for interoperability, but still needs to be complemented; The tested applications were not able to handle the entire shaping conveniently.
