Information Modelling for Planned Preservation. The HBIM model of Villa Forni Cerato

Abstract. The planned conservation of cultural heritage has found a useful tool in the HBIM approach, as the digitization of the process allows for effective access to documents, operations, and projects by various actors in the sector. The adoption of the HBIM approach has seen several key issues emerge, linked to the difficulties of geometric modeling (using a parametric paradigm) of built heritage and the management of big data such as point clouds. With these issues now established, it is time to consider the necessary insights related to information modeling, including for planned conservation. This need has an impact on the practical approach to the work, but also on contractual aspects. In terms of operational practice, information modeling allows HBIM models to be constructed that are easily accessible in all their information, updatable, and easy to use. From a more formal point of view, the definition of the information content in the EIR and BEP is a prerequisite for the proper management of the work and for defining, through an agreement, the characteristics of the work, the results to be achieved, and the methods to be used.
Information modeling is therefore at the heart of this research, which finds its application in Villa Forni Cerato, attributed to Andrea Palladio. The theme developed is that of wooden floors because, on the one hand, they have specific information content and, on the other, because the villa was designed by Andrea Palladio for his timber supplier.
