Estrategias de modelado patrimonial en HBIM, aplicación a la lectura estratigráfica del muro de fachada del cuadrante renacentista de la catedral de Sevilla

This paper discusses different heritage modelling strategies included in the HBIM model, analyzing the Levels of Knowledge –LOK– allowed by each of them. Starting with the photogrammetric digital capture of the Renaissance Quadrant facade of the Cathedral of Seville, an initial conceptual model has been generated, oriented towards the generic definition of the asset and its location in the context of cathedral ensemble. The archaeological and architectonical analysis of the constructive process have enhanced the knowledge of the study case and, therefore, the possibility to increase the level of development of the HBIM model, which have reached the three-dimensional characterization of every single basic constructive unit of the facade. Therefore, the stratigraphic analysis is not limited to the surface of the wall, but characterized as a three-dimensional reality, approaching thus the cathedral. The high level of knowledge reached by this model has made it possible to take it as basis for registering and managing heritage information, allowing themed graphic and alphanumeric views.
