“Digital specialist foundations ”- Using the Digital Twin During Project Execution-Paper

Paper

Pdf Summary

BAUER Spezialtiefbau GmbH applies digital methods across project planning, execution, and documentation to improve specialist foundation work. Its approach connects BIM planning with production and quality data, creating a digital twin that supports real-time monitoring and reuse of as-built information.<br /><br />During work preparation, linking the 3D model to the construction schedule automatically generates phase plans and rig-position drawings. These help teams identify geometric conflicts in advance. Updated plans also support weekly coordination and communicate schedule-related changes to clients and other contractors.<br /><br />For execution, BAUER developed the b-project data-management system to address the lack of suitable software for specialist foundation production. It combines standardized planning data, machine-generated production records, and manually entered quality reports in a structured database. Mobile apps, automated data consolidation, web-based evaluations, and report generation reduce manual documentation and make project information easier to analyze.<br /><br />The digital twin links construction records—such as concreting data—with material-test results. Standardized visualizations and filters reveal quality issues, performance trends, and opportunities to reduce waste. Web-based dashboards provide project stakeholders with timely access to key indicators, progress evaluations, and forecasts, including material-stock predictions that can help prevent work stoppages. Reusable visualizations speed up decision-making and enable earlier intervention, reducing defect and error costs.<br /><br />Production data can also be transferred into BIM and GIS systems for georeferenced as-built documentation and use in later project stages. Overall, structured, centralized data management improves reporting efficiency, quality assurance, process optimization, and timely decision-making. It also supports longer-term assessment of construction methods and project risk, establishing production information as an important part of the construction value chain.
