Incompatibilities observed in the CAD-to-BIM information transfer process

Abstract

Due to its innovative nature, Building Information Modeling (BIM) still faces challenges in its effective implementation in Brazil, such as the lack of trained professionals in the field, especially in the public sector. Therefore, in order to contribute to a change in this scenario, students from the Civil Engineering and Architecture and Urbanism courses at the Federal University of Santa Maria were challenged to transcribe an architectural project for a building under construction at the institution itself, with a total area of 1,228.70 m², originally in CAD format, into a parametric model using Autodesk Revit software. Several incompatibilities were observed in the process, for example, inconsistencies between the graphics and the respective descriptions in the memoranda, a factor which can delay important decisions in the executive phase, giving rise to failures. Finally, the main contribution of this work was to confirm the design superiority of BIM by enabling greater integration between professionals, a more assertive visualization of the technical part, a reduction in errors between the different views, and the generation of more intelligent models.
