Abstract

In recent years, the theme of technological evolution and digitalization has determined the construction of a different methodological research approach, which is based on the experimentation of innovative models to support the activities of survey, as well as structural and chemical analysis. This paper presents the results of an interdisciplinary work on the bell tower of the Melfi Cathedral (PZ), where integrated survey technologies and semantic analysis of architectural elements have been applied to develop advanced Heritage Building Information Modelling (HBIM) solutions. The HBIM model connects geometric and informational data through defined parameters, preventing data redundancy and fostering more conscious heritage management. Three-dimensional survey campaigns generated georeferenced point clouds, forming the basis for the digital twin of the structure. This data-driven approach also supports immersive storytelling. A virtual tour of the bell tower was created, structured around the HBIM model and its Level of Information (LOI). Elements with higher LOI are prioritized in the narrative for their historical and heritage value. This immersive experience enables visitors to explore the architectural spaces, while simultaneously accessing data about structural conditions, material analyses, and sampling results. The result is a comprehensive, informative, and engaging atlas that supports both public education and conservation planning.
