TRA “HISTORICAL BIM” ED “HERITAGE BIM: BUILDING INFORMATION MODELING PER LA DOCUMENTAZIONE DEI BENI ARCHITETTONICI

Historical buildings are the outcome of processes of modification and stratification occurred over centuries. The study of archival documents, building phases and constructive elements are very important for the historical-critical analysis, because these elements are witnesses of cultures, events and actors occurred during time. BIM roots on architectural design, but recent applications dedicated to architectural heritage show interesting potentialities. In particular the advanced possibilities of deriving 3D models from point clouds and the opportunity to enrich the object attributes with dedicated databases. In this way BIM can favor visual computing, and knowledge and design processes thanks to the possibility to “include” historical transformations and constructive systems, and be a core aggregator for documentation. Aim of the paper is to present a study on BIM as tool both for 3D and archival data and information management and analysis, correlating the 3D model with a dedicated digital archive. Therefore 3D modeling and database modeling are developed symmetrically, according to a common semantization organization and levels of detail.
