Os desafios do sistema BIM na pratica: O caso de uma obra residencial multipavimentos em Goiânia-GO

Abstract

The analyzed case study focuses on the multi-story project, in Goiânia-GO, which transitioned from a conventional system to BIM, facing challenges of adaptation and resistance. Interviews were conducted with project managers to identify difficulties, such as the lack of standardization and communication, and propose improvements. The research considered responses from three out of the four involved professionals, minimizing sampling error and increasing the representativeness of the conclusions. The methodology included qualitative interviews with the assistant, resident engineer, and project coordinator to detail the obstacles and propose solutions for more efficient project planning. The use of BIM in the project revealed both its benefits and limitations. While it offers 3D visualization and project integration, challenges arose with the coordination among disciplines, especially in installations (plumbing, electrical, fire protection), which caused rework, material waste, and delays, leading to increased costs and affecting the schedule. Engineers suggested centralizing the coordination in a specialized department and using clash detection tools to avoid inconsistencies. Despite the challenges, BIM allowed for the early identification and resolution of problems, showing that its implementation requires changes in workflows and intense collaboration among designers, with the use of updated project versions. Recommendations to enhance the use of BIM include the complete coordination of all projects before construction, the implementation of a Common Data Environment (CDE) to ensure efficient communication, and realistic schedules that allow time for analysis and adjustments. These practices minimize rework, delays, and costs, maximizing the effectiveness of BIM.
