Condition Information Models in the context of Structural Health Monitoring

Abstract

The realistic modelling of condition of structures with building information modelling (BIM) is beneficial for the assessment of structures. Condition survey in form of Structural Health Monitoring (SHM) and testing is one important source of data to support this task. However, the interpretation of data is even more reliable if the condition – or in the worst case – the damage of the particular structure is known. Therefore, the condition information should be easily available and preferably machine interpretable. Currently, standards for the integration and processing of condition/ damage information in BIM are missing. The integration of condition/ damage information in the BIM method is necessary for a more realistic representation of the structure. Going beyond the as‐build information towards the as‐is condition of the structure it requires information from Non‐Destructive‐Testing (NDT) and inspections in the BIM model. For that purpose, besides the information itself, it is crucial to define the interfaces between NDT and BIM for an automated transfer of data. The accuracy and reliability of the NDT methods is of importance to enable condition assessment. Consequently, this contribution provides a comprehensive approach for the integration of SHM and NDT data in BIM.
