A Flexible CAEX Based Model for Standard Integration in Tunnelling

This work addresses the issues in implementing interoperability and seamless data exchange in the multidisciplinary collaboration between different stakeholders in underground construction projects. We highlight problems that arise from employing tool-to-tool interfaces, and address the semantic heterogeneity and diverging perspectives in the standardized data models describing the sub-domain of subsoil surveying and interpretation. The subsoil is understood as the most important construction material in underground projects. We present a synthetic reconstructive approach to dealing with heterogeneous perspectives on the subsoil based on the neutral data format CAEX

Computer Aided Engineering Exchange https://www.plt.rwth-aachen.de/cms/PLT/Forschung/Projekte2/-ejwy/CAEX-IEC-62424/?lidx=1 and evaluate it in the use case of a subsurface information model. The aim is to enable a BIM -compliant modeling of its geological, geotechnical and hydrogeological properties as well as a universal translation strategy that focuses on data exchange rather than on different proprietary data formats. Our approach aims to facilitate integration without limiting the autonomy of data sources or the diversity of perspectives.
