GUD COMPOSIZIONI COMPOSITIONS. A Magazine about Architecture, Design and Cities

This paper investigates the relationship among the knowledge-generated processes
by traditional survey and restitution and those produced by digital surveying through
BIM modeling, in order to critically read the composition of buildings. The recent
scientific literature describes the efficiency of the digital model for the construction
of knowledge, challenging the analog representation according to information
availability criteria.
However, it remains unclear the identification of the methods, in BIM modeling, for
the definition of an architectural and structural model of monumental buildings.
Furthermore, it is necessary to clarify the role of two-dimensional representation for
wall textures, of statuary, as elements that characterize, in aesthetic and informative
terms, traditional restitutions.
The relationship between methods and results between analog and digital paths is
developed in the text through the case study of the cathedral of Albenga. Such a complex
building, whose main transformations are described, leads the discussion towards a
critical description of the contents of the representations. This thus demonstrates
some key steps of digitization, in particular with reference to construction elements,
proposing a mixed use between point cloud relief and BIM model.
