H-BIM Modelling for Enhancing Modernism Architectural Archives. Reliability of Reconstructive Modelling for “on Paper” Architecture

In recent years a culture of conservation has been developed also regarding Modernism archives, that come to us with their often considerable amount of materials. Valorization, interpretation, fruition and sharing of knowledge address the works of many international scholars. In particular, using the continuous innovations of digital modelling tools, a field of this research is developing reconstruction and new interpretations of masters’ unbuilt or demolished projects. Contemporarily to the rising of H-BIM for modelling architectural heritage, some experiments aimed to represent on paper architectures are exploiting BIM potentialities. Moreover, some recent researches links H-BIM modelling with displaying of uncertainties of digital reconstructions. The present research constitutes a step of experience aimed at the generalisation of a methodology for the visualization of the level of reliability of digital reconstruction of architectures starting from archival documentary heritage. The peculiarity of the case study, an architecture now documented on paper but which has completed its cycle of existence through construction and subsequent demolishment, and that of the archival fond, which has come down to us in fragmentary form, make it an interesting example because of the complexity of the issues it poses.
