Procedure per la modellazione HBIM del patrimonio architettonico

The book is dedicated to the study and the deepening of issues related to the knowledge, documentation and representation of architectural heritage through the development, experimentation and validation of HBIM procedures for the creation of customizable parametric models able to respond to the peculiarities of historical buildings, which can therefore be configured as useful tools to testify the historical - architectural values of the assets. The present work highlights the differences between BIM and HBIM, critically underlying the problems and potential of this procedure, which should not be understood as an extension of the BIM approach to historical buildings but differs from the latter in that founded on a different theoretical and methodological approach. HBIM procedure, in fact, refers primarily to a process of knowledge that starts from the survey, critically analysed and subsequently semantized, and leads to its critical restitution through the HBIM modelling. The model is no longer only an instrument of interpretation and representation, but a critical instrument of analysis and knowledge. Therefore, in order to obtain a scientifically valid modelling, the importance to declare and evaluate the sources on which the interpretative process is based appears evident and renewed. This consideration is amplified by the transition from two-dimensional representation to three-dimensional virtualization, which requires a geometric-dimensional and informative synthesis extended to the entire continuum of the artefact, and by the often incomplete knowledge that characterizes historical building. The main objective of the research concerns the development of procedures for the creation of HBIM models starting from the cognitive and documentary phase, by defining standards for their construction and validation. The achievement of these aims was reached also through the experimentation with visual programming tools, which aided to overcome some of the HBIM limits relating to the parameterization of complex elements typical of historical architecture, the expansion of the BIM database, to allow the documentation of the heritage, and the evaluation and declaration of the geometric and informative reliabilities of the models. Lastly, the proposed procedures and standards are tested and valitated through the HBIM modelling of a chosen case study.
