Abstract This article presents an innovative approach to structured information exchange in ground modeling, integrating geology, geotechnics, and hydrogeology. It proposes a data framework seamlessly merging the DAUB's modeling guidelines with the University of Innsbruck research. Addressing diverse data management challenges and ensuring interoperability, the workflow offers solutions for CAD‐ and interpolation‐based modeling, enabling semi‐automated generation of Geotechnical Synthesis Models with open file format export. Overcoming obstacles, the article introduces a uniform rasterization method, defining a tunnel‐specific repository voxel (Tuxel). Results showcase a streamlined, semi‐automated process using Autodesk Civil 3D® and Seequent Leapfrog Works®, enhancing data uniformity and enabling cross‐project information exchange. This workflow provides practical solutions for collaborative ground modeling within BIM/TIM frameworks, fostering efficient and standardized data handling.
