Coordenação de projetos em edificações públicas: uma análise comparativa entre as metodologias BIM e CAD

Abstract

This study investigates the application of Building Information Modeling (BIM) methodology in the modeling and compatibility of projects related to a public administrative block in the municipality of Capitólio-MG. The research comprised: (i) bibliographic review; (ii) the modeling of the projects using Autodesk Revit software, based on PDF files made available through the bidding process for the project; (iii) the organization of the projects into separate files, aligned by a common base point; and, (iv) compatibility in Navisworks, using the Clash Detective tool with a tolerance of 0.010 m and grouping of equivalent occurrences. In the modeling phase (Scenario 1), the failures were classified into three categories: lack of information, inconsistencies, and incompatibilities, the latter being the most representative, especially in building installation projects. In the post-modeling phase (Scenario 2), conflict detection revealed cases with a high potential impact on the construction, while also highlighting less critical occurrences, emphasizing the importance of technical judgment for the prioritization and correction of conflicts. The compatibility check performed in Scenario 2 confirmed the predominance of conflicts in facility projects, reinforcing the findings of Scenario 1. The choice of the Navisworks Cache (NWC) format over the Industry Foundation Classes (IFC) proved to be more strategic in terms of software interoperability. This decision was made because the project was developed within the Autodesk ecosystem, which favors the preservation of shared links, materials, and coordinates, increasing traceability and confidence in compatibility. The research proved that the BIM methodology contributes significantly to accuracy, predictability, and quality in project development, with particularly relevant results throughout the construction process.
