HBIM and digital documentation for development reliable parametric models on complex systems

The model construction, which is not a simple skeleton of geometric shapes, as a structured system of information, is a particularly useful tool for the management of the complex systems of Cultural Heritage. These tools improve the accessibility to the complex systems, according to different interconnection channels. Cultural heritage has become an open-data access database of information ordered within a structured network of metadata.These kinds of files create a complex database. Through the digital survey, heritage became a 3D model that describes cultural systems as a union of languages, signs, and symbols. The contribution presents some methodological research experiences on monumental digital documentation carried out by DAda-LAB laboratory, of the Department of Civil Engineering and Architecture of the University of Pavia, on two different museum systems: the bath of the mosque, a portion of the monumental complex of the Alhambra in Granada (Spain), and the Historical Central building of University of Pavia (Italy). From this research, two H-BIM models were obtained built on the basis of the metric data of the digital survey with the aim of investigating the different possibilities of using this type of models from the management of the assets to the use of digitized spaces.
