HBIM METHODOLOGIES FOR THE ARCHITECTURAL RESTORATION. THE CASE OF THE EX-CHURCH OF SAN QUIRICO ALL’OLIVO IN LUCCA, TUSCANY

Abstract

Abstract. In the last decade, in the field of conservation of historic buildings, several research projects have shown the potential of applying BIM technology to architectural heritage. However, the use of BIM for historic buildings (HBIM) is still evolving. This paper presents an application of Building Information Modelling targeted to the development of a restauration proposal for the ex-church of San Quirico all’Olivo in Lucca, Tuscany. Following a brief review of the state-of-the-art of BIM applied to architectural heritage, the paper shows the results of a study that included 3D architectural survey with Structure-from-Motion methodology, critical analysis of historical archival and bibliographic sources, analysis of the conservation status of the building, proposal for its conservation and enhancement.HBIM methodology has been critically applied to all the phases of the project. This study also explores the possibility of organizing the BIM model into temporal phases, integrating documentation in a structured and easily accessible way. In our study, we also chose to link the 3D point cloud to the model, in order to increase the level of information; the 3D survey, therefore, is both the starting point for modelling, and represents a source of information within the model, to be recalled when required.
