Building Functional Rehabilitation Based on BIM Methodology

The Architecture, Engineering, Construction, and Operations (AECO) sector has innovated in the design and construction methods using new technologies, with emphasis on the Building Information Modeling (BIM) methodology. However, it is still necessary to explore how this methodology can be applied to rehabilitation, in general, and to functional rehabilitation. BIM has as its main advantage, the possibility of an accurate representation of the geometry of the elements, integrating the information in several dimensions. The use of digital models is very important, since it allows optimizing the visualization and detail of these elements and their constructive processes, being a collaborative methodology. The present work intends to frame the BIM theme in the building’s rehabilitation, namely, at a functional level, being presented with the development of a study in which BIM methodology is applied to a commercial building functional rehabilitation. The BIM model is built by surveying the existing use of the laser scanner and the existing plants, and later being exploited to obtain useful documentation, such as drawn pieces representing both demolition operations and new construction, in an application methodology. The main results of the research are discussed, and the corresponding conclusions are stated.
