Desde la representación hasta el modelo digital HBIM de un edificio histórico

This contribution is part of a field of research and studies related to the application of BIM (Building Information Modeling) systems for the documentation, restoration and management of Cultural Heritage. The article tackles the problems encountered and the solutions adopted in the process of transforming the data acquired through digital survey into an HBIM model of a small pantheon located in the cemetery of Castellón de la Plana (Spain). The methodology for the representation of a cultural asset by means of a BIM model does not present a unique and shared workflow, as it depends mainly on the characteristics of the case study and the purposes of the model, as well as the level of development required (LOD). In the case at hand, the goal is to create a BIM model that correctly represents the building, but which is above all a tool capable of meeting the needs of the professionals involved in the restoration project. The combination of the needs of documentation and representation with those of restoration has led to the adoption of specific workflows for the transposition of the building into a BIM model, each relating to different categories of elements (such as the iron fence, the floor, the decorations). This contribution explores in depth the process of creating the roofs, a specific case that exemplifies the main problems encountered in the process of creating an HBIM model.
