Digital Twin and Building Logbook for the Management of Heritage and Strategic Buildings: The BUILDCHAIN Demo-Pilot, Palazzo Poniatowski-Guadagni in Florence

Public authorities and the European construction industry face significant challenges in managing the huge existing building stock. Tools for information management such as Digital Building Logbooks (DBLs) and Digital Twin (DT) technologies have the potential to support monitoring and management of the built environment, enabling better decision-making throughout the building's lifespan. The BUILDCHAIN Horizon Europe project aims to demonstrate the possibility of using DBLs to achieve a smarter and more sustainable European built environment, building a knowledge base platform that can be used to keep track of all activities related to the building life-cycle, connect different actors, and provide new services based on innovative technologies. In the paper, an overview of the Demo-Pilot, Palazzo Poniatowski-Guadagni in Florence, is presented, starting from the acquisition of information by advanced survey techniques, the development of the Heritage Building Information Model (H-BIM) from point cloud, and the elaboration of a structural model to be connected and updated with the sensor data of the Structural Health Monitoring (SHM) system.
