ABSTRACT
Both the development of national and European directives and the widespread use of BIM (Building Information Modeling) generated the demand to study specific modelling practices for the analysis and conservation of masonry buildings. In this sense, masonry buildings differ from the practices of contemporary production, starting from the typical equivalence between architectural and structural objects. It becomes so important to establish on one hand the geometric rules for the passage of information between the BIM model and the FEM analytical models, on the other, a valid methodology to describe building pathologies for masonry surfaces. Starting from an analysis of analogic and digital methods to classify these conditions, the study shows two different alternatives for integrating information, usually embedded within two-dimensional drawings, in a BIM environment. Both processes allowed to create three-dimensional semantic objects related to specific information of type of building conditions, that could help the conservation and restoration of construction elements in masonry.
