Digital Twins for Contemporary Restoration of the Solimene Factory

The restoration of the Opificio Solimene, a post-World War II reinforced concrete building (Vietri, Italy 54–55), has been under discussion for some time. The study complements previous surveys, focusing on a sample of the masonry of the main façade. Close-range photogrammetry provides a precise and accurate description of the geometric anomalies and realistic photos of the interior of the infill wall. In fact, the degradation of the wall allows inspection at a convenient height for the acquisition of images and the direct measurement of certain details. The contribution discusses the experimental phases of the survey; it proposes some possible measurement operations within specific software for the management and virtual visualisation of the wall. The positive/negative 3D reality-based models obtained allowed static, functional and aesthetic investigations. The generalisation of the results aims to increase the information level of digital constructions. Degrees of possibility are addressed to identify a typological family that finds election in the management of Historic Building Information Model (HBIM) processes.
