BIM AND CASTELLO SFORZESCO IN MILAN. A PARTICULAR APPROACH TO DIGITIZATION OF THE ARCHITECTURAL AND INFORMATION HERITAGE

Abstract

In the architectural and construction field, the BIM methodology is becoming increasingly predominant and it has become widespread in recent years thanks to the advantages provided in the framework of project management and interoperability. These digitization processes have led to efficient standards for new construction interventions. On the contrary, more applications have shown how this process is far from univocal and linear for Architectural Cultural Heritage. These difficulties derive from the complexity of the constructions but also, and above all, from managing the information heritage connected to the digitized object. The work presented in this paper aims to define a general operating model, widely applicable, for the digitization of the information asset related to the architectural heritage, exploiting the digital model of the object. This theme has been declined concerning a particular case study, with monumental characteristics and value: the Castello Sforzesco in Milan. This research work starts from the information connected to this particular building, a countless and often extremely articulated heritage, due to its stratification over time. To better manage this complex aspect, an approach has been developed that starts from a 3D digital model of the Cultural Heritage (CH), associated to different levels concerning as many information packages (history, documentation, facility management, tourist fruition, etc).
