Operational Use Cases Using Resqml Standard to Communicate Geotechnics and Subsurface Information to Bim

Summary The aim of this presentation in four parts is to present how the RESQML format previously designed to exchange between Geosciences applications can be used in the Geotechnical domain by a BIM (Building Information Modeling) software to receive a global consistent image of the subsoil combining Geology, Geotechnics and DTM (Digital Terrain Modeling). We present the main RESQML principles, explain how the RESQML format (www.energistics.org) handle semantically the subsurface information, and demonstrate how EGIS GROUP, an Environmental and Infrastructure Company, was setting up a software environment with the help of a Geoscience expert to communicate subsoil information to a BIM oriented software (CIVIL 3D from Autodesk). Then, we show on several Use cases how the information is finally integrated in a BIM environment to be used by operational teams. These use cases were realized by RESQML CAD, A plug-in for Autodesk Civil 3D, developed in C#.NET under Visual Studio in collaboration between EGIS and GEOSIRIS. This tool is providing Geotechnical information as horizons and faults of the 3D models, drawing boreholes in 3D, drawing fence-diagrams and 3D logs data to this BIM software. Each drawn element is also associated to a list of attributes in a BIM database
