Uma análise dos benefícios da tecnologia BIM (3D E 4D) em projetos de obras públicas: estudo de caso de uma instituição de ensino

Abstract

Design and planning services for public construction projects are crucial to ensure their proper execution, avoiding compatibility issues between different project disciplines, and ensuring the efficient use of resources required for construction, in order to achieve the desired objectives. Failures or inconsistencies at this stage can result in delays, incomplete infrastructures, and waste of public resources. The use of Building Information Modeling (BIM) can be a valuable approach for the design and management of public works. This study aims to clarify the benefits of the BIM methodology, exploring its functionalities in the 3D and 4D dimensions in public works projects through a case study in a building of a public educational institution, whose projects are in 2D CAD format. Autodesk Revit software was used for the 3D modeling of the building's architectural, hydrosanitary, and structural projects, and Navisworks was used for its subsequent coordination and virtual simulation of the construction. Various inconsistencies between project disciplines became easily identifiable during the 3D modeling phase of the building. Thus, after computational coordination, a total of 515 active interferences were identified. Regarding the planning, a 7-month delay in the construction was noted.
