Report on the BIM-based building permit

Contact: Markus König, Marcel Stepien

The research project „BIM-basierter Bauantrag - Konzept für die nahtlose Integration von Building Information Modeling (BIM) in das behördliche Bauantragsverfahren“ funded within the framework of the innovation programme Zukunft Bau by the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) was successfully completed. It dealt with the use of BIM models for building planning and building regulation administrative procedures.

XML schema definition for DIN EN ISO 23386-compliant provision of properties and groups of properties

Cantact: Sven Zentgraf

The XML Schema Definition (XSD) can be used to create properties and groups of properties that conform to the data schema introduced in DIN EN ISO 23386 version 2020. The information elements created in this way can be created, maintained, and linked using the methods described in DIN EN ISO 23386 to create interconnected data dictionaries.

Excel tool for data collection ISO 23386

Contact: Sven Zentgraf

At the Chair of Computing in Engineering, an Excel tool was developed in the course of early research projects on the topic of property recording, which enables the recording of large quantities of properties and groups of properties at once. All mandatory and some optional attributes from the data schema of the standard can be captured via the tables of the workbook. A rudimentary recording of the relationships between properties and groups of properties is also possible via the Excel tool. More detailed documentation for capturing relationships and a list of optional attributes that cannot be captured via the Excel tool can be found in the documentation of the GitHub repository.

To be able to convert the collected and recorded attributes of the properties and groups of properties into a machine-readable format, the developed Excel tool has an XML converter implemented in Visual Basic. The XML files generated satisfy an XML schema (XSD) that reflects the syntax of the data model presented in DIN EN ISO 23386. The development of this schema also took place in earlier research projects at the Chair of Computing in Engineering.

This dataset consists of 370 RGB images of cracks on concrete structures and the corresponding segmentation masks. The dataset can be used for classification, recognition and semantic segmentation tasks.
