Concept for the integration of BIM and GIS data for monitoring land deformation around an ongoing infrastructure project

Abstract

[EN] The BIM (Building Information Modeling) technology, currently being introduced in many countries, and its integration with GIS (Geographic Information System) data within a single CDE (Common Data Environment) platform may allow a more in-depth monitoring of the investment and faster detection of irregularities related to its implementation. Considered separately, each of the above technologies allows different types of analysis, but the synergy effect created by their integration makes it possible to view the problem in a broader perspective and to make the optimal decision. This issue also concerns the analysis of deformations around the erected object, which can be described by GIS data. On the other hand, the object is currently most often represented by a 3D model in IFC format that has the relevant information. The main aspect of this work is to combine these two types of data and analyse such a solution in terms of investment management support. The final result of the work is a description of a BIM and GIS use case for deformation monitoring and the creation of a algorithm for this task including the exchanged information with reference to OpenBIM standards (data exchange format Industry Foundation Classes - IFC, Information Delivery Manual - IDM). The whole work was also considered with reference to risk management during the project.
