Case study of analysis of interferences between the discipline of a building with conventional designs (re) modeling in BIM

ABSTRACT

Building Information Modeling (BIM) provides for the creation of a digital parametric model. The database created enables the extraction of concise information at all stages of the development of the enterprise. This concept goes beyond three-dimensional modeling and aggregates concepts of team integration, interference analysis, compatibilization and multi-dimensionality to the designing act. The objective of this article is to demonstrate, using a case study, the use of the BIM platform for the modeling and analysis of the interferences of the projects architectural, structural and hydrosanitary. For this, a three-dimensional modeling was done from projects, in 2D and digital boards, that were made available by the engineers responsible for the project, after its construction. The architectural design was first modeled in Revit®, followed by the hydrosanitary and finally the structural one. The three-dimensional models were then confronted in Navisworks®. As a result, it was possible, through the creation of the digital model, to quantify the existing interpositions at the structural/hydrosanitary interface. In this way, after the execution of the analysis, it was possible to verify which interferences could have been solved already in the design phase, thus avoiding eventual problems in the execution. The interoperability of software provided by the BIM platform and the extraction of information from the database generated by the modeling were verified in practice. This concludes the possible benefit of applying it both at the project stage and at the time of implementation.
