Abstract

HBIM methodology is increasingly used for the management of all aspects of architectural heritage, from survey and analysis to conservation, management and restoration issues. Application of HBIM are the so-called Scan-to-BIM processes in which the artifact is surveyed with digital techniques of laser scanning and photogrammetry. These techniques result in point clouds, the basis of the subsequent process of informative and geometric modelling of the artifact. The resulting "smart models" are composed of parametric objects rich in information that can be easily updated at any time. The proposed methodology aims at integrating a study of architectural orders, whose results become preparatory to the subsequent phases of survey and modeling, to the classic Scan-to-BIM workflows. In particular, in the modeling these results have allowed a more targeted choice of techniques used. The method has been applied to the atrium of the former Jesuit College of Santa Croce in Cagliari, which today hosts one of the seats of the Faculty of Engineering and Architecture of the University of Cagliari; in particular, the atrium of the east body of the former Jesuit College, designed by the Piedmontese architect Antonio Felice De Vincenti, has been modelled.
