STRATIGRAPHIC UNITS INSIDE HERITAGE BUILDING INFORMATION MODEL: A NOVEL APPROACH FOR THE REPRESENTATION OF BUILDING ARCHAEOLOGY

Abstract. The paper discusses the representation of Stratigraphic Units (SUs) and the communication of Building Archaeology analysis in three dimensions within the context of Historic Building Information Modeling (HBIM). The author propose a methodological approach to incorporate 2D Building Archaeology analysis into the HBIM environment, aiming to support experts involved in research and restoration phases. Moving from 2D to 3D graphics in Building Archaeology introduces challenges in describing the third dimension of SUs, particularly regarding thickness and the relationship between different wall layers. In conclusion, the paper suggests the creation of a new category of HBIM called Building Archaeology Informative Modelling (BAIM), which aims to address the specific requirements of representing Building Archaeology in three dimensions.
