Modelagem de objetos BIM: estudo de caso com elementos estruturais pré-fabricados de concreto armado

Abstract

Building Information Modeling represents a disruptive methodology in the context of project development in architecture, engineering and construction. The various advantages of using this novelty imply gains in terms of productivity and reduction of errors and rework. In this context, several manufacturers in the civil construction sector seek to develop libraries of BIM objects to facilitate the specification of their products by designers. This trend should be especially interesting for the prefabrication industry, since the design specificities of this construction method can be met through the various functionalities offered by BIM. Thus, the present work has the general objective of exploring the possibilities of combining this methodology with prefabrication, through the parameterization of BIM objects that represent prefabricated structural elements. For that, Autodesk Revit was used to create parametric families that represent products from previously researched local suppliers. Applying the resulting files in a BIM model, it was possible to attest the practicality of parametric editing of model objects, as well as to point out the possibilities of extracting information for analysis and generation of tables in an automated and intelligent way. Thus, it is noticeable that the three-dimensional model based on parametric objects consists of just one of the many potentialities that BIM can offer, making it possible to explore applications in other areas of engineering such as budgeting, planning and various analyses.
