HBIM FOR RESTORATION WORK AND MONITORING OF COMPLEX ARCHITECTURES: THE FAMILY CHAPEL OF RAMÓN PERES Y ROVIRA IN CASTELLÓN DE LA PLANA (SPAIN)

The paper analyses the procedure to create a 3D model of a neogothic family chapel situated in Castellón de la Plana (Spain). The characteristics of the case study make it an emblematic case of Building Information Modeling (BIM) applied to Cultural Heritage (Historic BIM). The paper explores the workflow used to create the model and how the difficulties encountered have been addressed. The key motivations for this research project are: (i) local authority needs and objectives (restoration works for the conservation of architecture; necessity to monitor the asset after restoration); (ii) the intrinsic peculiarities of the small building (vast diversity of materials, richness and diversity of decorative elements); (iii) the creation of a pilot project for future applications in similar architectures. The chosen workflow tries to tackle the principal issues shared by the academic world with respect to 3D and HBIM models, e.g. the difficulty in reconstructing complex architectures without time-consuming processes, the reliability and high detail in the rendering of colours and textures, the insertion of detailed information for each element. The experiments carried out have made this case study interesting because of its complexity despite its reduced dimensions.
