Thus, the consideration of a vir- tual and informative Abacus of Stones has been undertaken to make it an effective tool of knowledge and management for future actions. Abstract The revolution of the BIM methodology lies in the informative component attributable to digital entities, more challenging to define for the historical buildings due to the need to resort to documentary sources and diagnostic investigations instead of datasheets or virtual “pre-packaged” objects. In line with a research about the shell stone facing of the Station of Messina, a stylistic feature recurring in the public buildings of the 1930s-1940s, this study aims to conceive specific “H-BIM objects” so that they can Alessandra Cernaro represent new channels for collection and processing of data, in support DE - Dipartimento di Ingegneria, of adequate Building Dossier and Maintenance Plan for cultural heritage.
