Digital reconstruction for the documentation of the heritage: the case of Vilanova Artigas Building

ABSTRACT The aim of this paper is to present and discuss the approach adopted for the elaboration of digital models of the Vilanova Artigas building, focusing on the meaning, uses and limitations of several models and survey methods as well. The digital reconstruction of the building, and its parts, was carried out based on conventional topographic survey with total station, 3D laser scan associated with photogrammetry, metric survey using manual instruments and visual analysis associated with photographic record. The modeling process, through the integration of several methods, allowed the gathering of historical data, laboratory analyses and on-site tests, enabling classification and registration of useful information for the future conservation management plan of the building. The conception of a single model proved to be infeasible; specialty requires specific data which may even use different geometric delimitations (modeling) of the constituent parts of the building. It is proposed a simplified model with the objective of generally delimiting the geometry of the building and then each specialty would use this preliminary information to design the model that best meets its objectives.
