O uso do BIM na análise de interferências entre os projetos de uma edificação pública elaborados em CAD 2D

Abstract

The use of CAD (Computer Aided Design) tools for the compatibility of projects is ineffective in several aspects, so that many incompatibilities go unnoticed in the design phase, resulting in adaptations in the execution, thus causing an increase in the final cost of the product. The use of the BIM methodology (Building Information Model) is essential and mandatory in the elaboration of public projects, highlighting the professionals who have this knowledge. Therefore, this research seeks to demonstrate the superiorities of the BIM methodology for the analysis of interference between the architectural and complementary projects of a public building, whose technical parts have been developed using the 2D CAD methodology. The modeling of the projects took place with the use of software with BIM support, from two different manufacturers through the IFC specification, using the Revit software (Autodesk) for the modeling of the architectural project, QiBuilder (AltoQi) for the modeling of the eletric and hydrosanitary installation projects and Eberick software (AltoQi) for structural design modeling. Finally, the Navisworks software (Autodesk) was used in the analysis of interferences in which, analyzing the projects pair by pair, numerous incompatibilities were obtained that could be avoided even in the design phase, ensuring greater security if the structural reinforcement check was implemented in the holes and openings in the structural elements and optimization of electrical and water-sanitary installations in case they were relocated.
