Aplicação da metodologia BIM para projeto e orçamentação de obra de reforma em escola pública de ensino

Abstract

In the Brazilian context, the inefficient management of public renovation works compromises educational infrastructure. These projects, marked by successive change orders and work stoppages, hinder the provision of adequate school facilities. Building Information Modeling (BIM) represents an innovative approach in the construction sector. This methodology provides greater project accuracy and reduces the occurrence of contractual amendments and budget overruns. In this context, this study aims to develop BIM modeling and cost estimation for the renovation projects of a public school within the public education system. Based on the existing architectural CAD drawings and an on-site survey, BIM models were developed for the architectural, electrical, hydraulic, sanitary, and structural disciplines. From the BIM models, quantity takeoffs were extracted and used for cost estimation using the Seobra® software. The results reaffirm the potential of the BIM methodology for quantity extraction and cost estimation, supporting the delivery of efficient and functional projects. This application highlights the effectiveness of BIM tools, resulting in coordinated and efficient project delivery, as well as accuracy in generating the total construction cost estimate.
