PROJETO DE INSTALAÇÕES ELÉTRICAS RESIDENCIAIS COM APLICAÇÃO DA METODOLOGIA BUILDING INFORMATION MODELING (BIM)

Abstract

The objective of this study is to develop a residential electrical installation design using the Building Information Modeling (BIM) methodology, while comparing it with traditional design methods. The study covers the stages of conception, sizing, and representation of the electrical design, taking into account the recommendations set forth in NBR 5410 and other standards. The project modeling enabled the configuration of electrical points, the entry of loads, the division of circuits, and the sizing of conductors, protective devices, electrical conduits, and the distribution panel. Compared to the conventional workflow, the use of BIM provided greater integration with the architectural design, in addition to the automatic generation of load tables, electrical diagrams, and material lists—processes that, in traditional methods, are usually manual and prone to errors—thereby helping to reduce errors, shorten the time required for execution, and ensure greater reliability of the technical documentation. The results show that the application of BIM in residential electrical projects provides significant gains in organization, accuracy, and coordination when compared to standard design practices, standing out as an efficient tool for the development of electrical installation projects.
