Title:	Evaluation von Software zur Generierung von Baugrundschichtenmodellen
Abstract:	Im “Stufenplan Digitales Planen und Bauen” des Bundesministeriums für Verkehr und digitale Infrastruktur wird für öffentliche Infrastrukturprojekte gefordert, die Methode Building Information Modeling anzuwenden. Daraus folgt die Forderung der Bundesfachabteilung Spezialtiefbau im Hauptverband der Deutschen Bauindustrie e. V. nach einem Fachmodell Baugrund vom Auftraggeber. Das Fachmodell soll aus der Erdoberfläche in Form eines digitalen Geländemodells, dem Bodenschichtenmodell und auch den zugrunde liegenden Daten von Bohrungen, Vermessung etc. bestehen sowie Schichtinformationen und Bodenkennwerte des Baugrunds auf der Basis des geotechnischen Berichts enthalten. Der Verlauf der Schichtgrenzen zwischen den Aufschlüssen ist dabei durch Anwendung von Interpolationsmethoden abzuleiten und durch manuelle Nachbearbeitung anzupassen. Um diese Herausforderungen zu meistern, werden hierfür verschiedene Softwares evaluiert. Evaluation of software for the creation of soil models In the “Road Map for Digital Design and Construction” of the Federal Ministry of Transport and Digital Infrastructure (BMVI), public infrastructure projects are required to use the Building Information Modeling (BIM) method. As a result, the Federal Department of Foundation Engineering of the Federation of the German Construction Industry (Hauptverband der Deutschen Bauindustrie e. V.) demands a discipline-specific model for foundation soil from the client in its technical position paper. The discipline-specific model should consist of the earth's surface in the form of a digital terrain model (DTM), the soil layer model and also the subsoil data on which it is based (drillings, survey data, etc.), as well as layer information and soil characteristics of the subsoil on the basis of the geotechnical report. The location of the layer boundaries between the outcrops is to be derived by using interpolation methods and adjusted by manual post-processing. In order to manage these challenges, different software is evaluated.
