Product Data Management for Existing Buildings (Retro-Digitization)

For efficient facility management or well-founded renovation planning, seamless digital documentation of existing buildings is essential. The retro-digitization service closes this information gap by systematically transferring a building’s physical components into the digital world. The process begins with data capture, where specialists record defined and identifiable products or building elements directly on-site or using existing plans and documentation. Next comes data compilation, where all relevant information for each recorded product is gathered from available sources—ranging from old delivery notes and revision plans to current manufacturer data. In the final preparation step, this heterogeneous data is transformed into a clean, unified structure and delivered in the required format (e.g., CSV, XLSX, IFC). The result is a high-quality, structured dataset that serves as a solid foundation for all subsequent processes, such as building a CAFM system or creating an as-built BIM model.
