IT Procedures For Simulation Of Historical Building Restoration Site

Dealing with renovation and restoration of historical building heritage, often means facing several difficulties concerning the way of representing not only the ancient building and the design ideas, but also phases of interventions on site. The designers have always to take into account a range of possible compatible solutions that avoid endangering the cultural significance of the historical building. Traditional methods are often time consuming and barely efficient, because they are related to exchange two-dimensional and paper-based support information. The Building Information Modeling may represent an answer to these problems, allowing the users to model the three-dimensional compounds of the building and to link a variety of information to it. This work intends to propose an innovative approach to the construction management of historical building interventions, based on BIM technologies, facing different kinds of problems, such as: parametric modeling of historical buildings, starting with laser scanner survey: LoD (level of detail) definition and measurement accuracy related to modeling procedures; parametric modeling of the site and the several phases of the restoration works in a fixed schedule (4D dimension); 3D graphic representation of safety procedures and related tools. The case study was offered by the SS. Nome di Maria church (Italy), built in 1748, which was seriously damaged during the earthquake that occurred in Italy in 2012.
