Creating a Tool for Transforming Digital Requirements when Uploading Digital Information Models in IFC Format

Introduction. Modern computer-aided design (CAD) systems make use of digital information models (DIM) depending on the aims of a project. According to the Decree of the Government of the Russian Federation No. 614, Section 7, Subsection D, the use of information modeling technologies (IMT) does not always imply designing a DIM. However, making sure DIM attribute data are in compliance with a customer’s requirements or those of expert evaluation remains time-consuming and prone to technical errors. The relevance of the study is due to the need automated DIM parameter matching based on the technical specification requirements, which would reduce time costs and improve the quality of uploading the model. The study looks into the problem of the lack of tools for automated parameter matching based on machine-readable requirements. The aim of the study is to develop an application providing programmatic comparison of CIM attribute data in compliance with the technical specification requirements.

Materials and Methods. The software solution is being developed for a range of CAD systems, such as Renga Professional, CADLib "Model and Archive", Autodesk Revit. The article examines methods for generating parameter matching files specifically for Renga Professional. Throughout the study the following software was used: Renga Professional, Visual Studio Code, BimVision. In order to develop the application and algorithms, the Python programming language was used with the following libraries: PyQt6, openpyxl, et_xmlfile.

Research Results. A software solution has been developed that enables one to automatically match the DIM attribute data with the specified ones based on machine-readable requirements. The application provides the conversion of machinereadable requirements into a machine-readable DIM attribute data mapping file. Testing has shown a reduction in the time required to create parameter matching files in comparison with manual file generation. The resulting tool has the flexibility of implementation allowing one to upload existing requirements, as well as create one’s own and use them while uploading a model.

Discussion and Conclusion. From a practical standpoint the resulting application is highly significant for an investment and construction project, where, while designing a DIM in compliance with the current regulations, it is necessary to make use of an open standard for the data presentation format - Industry Foundation Classes (IFC). The application allows one to minimize routine operations while designing a DIM from a proprietary format into the IFC format. The research is promising as its future directions include expanding the functionality to be able to work with additional data formats and integration with other BIM platforms. The research results contribute to the development of methods for automated processing of DIM requirements.
