Abstract

Thanks to the development of technologies for digitalization, new possibilities of management and valorization of Cultural Heritage have been opened. These issues are addressed by the project IDEHA (Innovation for Data Elaboration in Heritage Areas), funded by MIUR Italian Ministry, for Italian assets of historical interest. Among the different case studies, the library tower of the XX Century complex of the Faculty of Engineering in Bologna has a great significance as an example of rationalist architecture. The present work aims at the 3D digitization of the tower, the analysis of its state of maintenance by using active thermography and the implementation of a BIM model that contains all these information. Aerial (by UAV) and terrestrial photogrammetry was used for the development of the three-dimensional model. From the acquired images, a point cloud and a textured mesh of the Tower were processed. The point cloud was also used as a reference for the elaboration of an HBIM model representing both the interior and exterior of the tower structure. Moreover, a study of the conditions of the external facades recently treated with water repellent was conducted through active thermography. The study of the state of the external brick wall face was carried out through the multi-temporal analysis of thermal images. This allowed to identify the areas where the water repellent treatment is damaged and therefore more exposed to deterioration phenomena. The main challenge of this research work is to incorporate the information acquired through active thermography into the information model in order to better manage the building.
