The artistic, architectural, and historical peculiarities that the Cultural Heritage incorporates make it necessary to have an exhaustive replica in 3D digital format, essential to monitor the historic building and all its contents, thus covering the phases of auscultation, intervention and conservation. But it is indisputable that managing the historical typologies of the archaeological, architectural and artistic heritage is a great challenge, since we find particular geometries, affected by diversifications of styles, peculiarities derived from the construction technique used in the place or by the human execution of the construction system, in addition to the transposition of styles and the deterioration suffered by the passage of time. Therefore, the modeling processes of these peculiar elements usually require more attention and care, which translates into considerable investments in both resources and time. The problem is complicated by bringing modeling to a parametric and precise environment, using the collaborative Building Information Modeling (BIM) system. The modeling process in a parametric environment is essential to effectively manage the dimensions of the part or system, automating the adaptations of its shape in specific cases. But having a library of historical parametric objects that covers the 3D representation of the features of historic buildings is still a major challenge. It is here that precise surveying, aided by scanning and photogrammetry techniques, has taken on a major role in the faithful representation of heritage. The research, therefore, deals with the study and implementation of effective techniques for the faithful representation of the Architectural Heritage, initiated in the metric survey of architecture by means of scanning and photogrammetric technique and culminating in the programmed parameterization of the 3D object. The document presents several methodological processes involved in the SCAN-to-BIM workflow, complementary to each other, and which aim to automate the modeling processes of heritage elements. For a proper implementation, the crypt of San Nicola Pellegrino (twelfth century), located at the head of the Cathedral of Trani (Bari, Italy), has been taken as a case study, and which is a characteristic example of the Puglian Romanesque. It is intended that the processes applied in the morphologies of the site provide parametric typologies for the 3D modeling of a large series of buildings with the same style.
