Digital geotechnical information management in a life cycle perspective
Digital geotechnical information management in a life cycle perspective
Heading towards sustainability a lifetime perspective is required for geotechnical information management. The GeoBIM concept has been developed, always enabling 1) Easy access to all geotechnical data for all stakeholders, 2) Design managed by geotechnical uncertainty control, 3) Flexible workflow and quick adaption to the user needs. This allows a smooth, quality assured and efficient workflow for any geotechnical design applications, and a significantly updated ge- otechnical process. Gathering different data sets in the same digital environment enables joint interpretation of any data sets, allowing use of the whole available data set in the most optimal way. Common issues in geotechnical engineering are un- certainties concerning the geological model and the design values. Tools have been developed for handling uncertainties of the layering, i.e., the bedrock model, and the design values. By adding as built geotechnical information to the database (surveyed bedrock model, geotechnical structures) a digital geotechnical asset management model (digital twin) could be handed over to the client for maintenance. A new geotechnical workflow is suggested, governed by a constant update of the uncertainties. Following this process activities like investigation program could be optimized and risk sharing between client and contractor could be clearer.
