SeeBridge (Semantic Enrichment Engine for Bridges) had the aim to discover solutions for rapid and intelligent survey and assessment of bridges. The end deliverable of the project was the SeeBridge system which targets to fullfil the following objectives:
- Data Collection
- 3D Reconstruction
- Semantic Enrichment
- Damage Detection
As demonstrated below, the output of the Seebridge system is a Bridge Information Model (BrIM), representing the state of a bridge for decision-making purposes concerning repair, retrofit or rebuild. For more information about the project please visit the main website.
From Information Delivery Manual to Model View Definition
An Information Delivery Manual (IDM) was created to formally describe the processes and the exchange information requirements in detail. BIMQ. information requirements database, was deployed for developing the Model View Definition (MVD) and its documentation in mvdXML format. The below diagram represents the workflow, which included iterative review processes to finalize the IDM and MVD.
The processes and exchange requirements extracted from Information Delivery Manual were adopted in the BIMQ as an information requirements catalogue. A special emphasis was given to map the required information to IFC4 Add2 Schema. After this basis is established, it is possible to export reports, property templates and checking rules. This allowed the automated generation of an mvdXML file directly from the catalogue in BIMQ. Finally the mvdXML was used to check the bridge models against exchange requirements automatically using XBIM Explorer.
“In the Seebridge (Semantic Enrichment Engine for Bridges) project, we used BIMQ to define the exchange requirements for all of the various processes. Without BIMQ and the flexibility it provides, we would have had to define the exchange requirements and the MVD separately. This would have been more difficult, because this is a dynamic design process, in which the requirements and the MVD must be updated continuously and remain consistent. In addition, the XML output from BIMQ allowed us to run automated checks of IFC exchange instance files for compliance to the MVD (which was bound to the IFC standard).”Rafael Sacks, Technion Israel Institute of Technology (Project Coordinator)
