HBIM as support of preventive conservation actions in heritage Architecture: experience of the Renaissance Quadrant Façade of the Cathedral of Seville

This paper discusses the generation of Historic Building Information Models (HBIM) for the management of heritage information aimed at the preventive conservation of assets of cultural interest, through its experimentation in a specific case study: the façade of the Renaissance quadrant of the Cathedral of Seville. Two methodological aspects are presented: On the one hand,the process of modeling the solid entities that compose the digital model of the object of study, basedon the semi-automatic estimation of the generating surfaces of the main faces; on the other hand,a methodological proposal for the modeling of information on the surface of the model. A series ofimages and data tables are shown as a result of the application of these methods. These representthe process of introducing information related to the current conservation status documentation and recording the treatments included in the preventive conservation works recently developedby a specialized company. The implementation of the digital model in the exposed work validatesit as a solvency option, provided from the infographic medium, when facing the need to contain,manage and visualize all the information generated in preventive conservation actions on heritage architecture, facilitating, in turn, cross-cutting relationships between the different analysis that resultin a deeper knowledge of this type of building
