“Digital Specialist Foundations”—Using the Digital Twin During Project Execution

This paper explains how BAUER Spezialtiefbau GmbH uses digital methods on projects—starting from work preparation to completion of works. More precisely, the advantages of BIM-based planning during work preparation and the automated and structured data management—both machine production data and the manually recorded quality-relevant reports—during execution phase are displayed. In this context, the benefit of the digital twin to optimize processes, to reduce defect costs, for a more effective reporting system, and the further usage of as-built information in the BIM or GIS process are described.
