This paper investigates ways to improve the integration between the geotechnical and infrastructural designing, modeling and analyzing processes. Up till now these three planning stages have been executed separate and without data exchange between each other. This separation leads to a time-consuming and expensive manual re-input of geometric and semantic data. Currently, roads are designed using a traditional approach which is based on various 2D drawings and is focused on the roadway itself. Additional geotechnical conditions such as the slope angle of the dam or the position of a retaining wall are not considered. To solve these problems, a new parametric and 3D-model based approach has been developed in the research project 'ForBAU - The virtual construction site'. This new approach is based on the traditional 2D infrastructure planning process which is extended by a new parameterized 3D modeling concept. Different open data formats such as LandXML and GroundXML allow data integration with both, a parametric Computer Aided Design (CAD) system and geomechanical engineering software. An automatic update function ensures data flow without loss of information. Use of this new approach will accelerate the infrastructure design and provide a parametric 3D-model approach which will close the gap between the geotechnical and infrastructure planning process. This paper strives to provide detailed information about this new integration concept and gives an overview on the various implementation steps.
