Geotechnical engineering and process of digitalization – BIM modelling

Abstract

The digitization process has been going very fast lately as well BIM modelling, as both are strongly connected. The paper briefly evaluates this process from different levels, with the main focus on the conceptual level. The 3D geotechnical model of the ground comes to the fore, as this ground plays an important role also in the process of the BIM because practically all building structures are situated on this ground. Since the EN 1997 Geotechnical design also uses geotechnical and computational models, their connection with the BIM process is very useful and brings new possibilities. Especially from the point of view of connecting the design of the superstructure with substructure and ground and thus the presentation of the result in BIM model of the whole building. BIM models are presented not only for foundation structures, but also for earth structures and their advantages are shown, especially from the view of the decision-making process, as in the design and implementation phase so in throughout the service life of the building.

From Geotechnical Data to GeoBIM Models: Testing Strategies for an Ex-Industrial Site in Turin

“…The purpose of this study was to obtain a better understanding of the current state of the art of the different available methods and tools for using BIM as a support tool and a source of information for reinforcing the efficient and effective planning, management of underground construction. Within this framework, this pattern of the results is consistent with the previous literature [7][8][9][10][11]. Whereas previous researchers focused on the development of new integration approaches [12][13][14][15][16][17][18] or on the optimisation of geotechnical investigations through the connection to the BIM environment [24][25][26], the present study shows the possibility of developing a tool that is able to support designers and technicians towards the selection of the most appropriate procedure based on the specific requirements of the project.…”

“…Several unresolved issues were identified in those studies, including differences in their modelling methods, the heterogeneous levels of detail and development of BIM and GIS at different scales, and the different uses of BIM and GIS [4][5][6]. Several authors have analysed the current status and prospects of using BIM, machine learning and computer vision techniques as support tools to reinforce the efficient and effective planning, development and management of underground construction [7][8][9][10][11].…”
