The paper investigates the advance in the most intimate understanding of the construction methods of the Fabrica Solimene (1952–1955) in Vietri sul Mare, (Campania-Italy). The aim is to increase the level of geometric and informative detail of the model, digitally (re)built by means of an indirect method using a total station survey and subsequently by means of a direct method, i.e., by importing the elaborations derived from laser scanner acquisitions and photographic data sets into a BIM authoring vector software. For this purpose, using photogrammetry, new details are acquired, specifically addressed to the study of the static-mechanical behaviour of the perimeter wall studied in its mathematical configuration of the projecting bodies from bottom to top. This study is organised on the elaboration of new clean and decimated point cloud acquisitions to be converted into volumetric models for direct use in finite element calculation (FEM) codes aimed at structural analysis. Thanks to the proposed procedure, it possible to maintain the level of geometric detail appropriate to the resolution required for the analysis. At the same time, it makes it possible to find the best pipeline to reduce the size of the model and obtain the most accurate static-structural results.
