Análise da aplicação da metodologia BIM 5D para o planejamento e controle de custos de um projeto residencial: estudo de caso

Abstract

The increasing use of the BIM methodology has promoted significant advances in the processes of planning, coordination, and management of construction projects in the civil engineering sector. In this context, BIM 5D stands out for integrating the virtual model with budget items, enabling greater accuracy in quantity takeoff, as well as greater reliability and traceability in cost estimation. Therefore, this study is justified by the need to explore practical applications of this methodology, highlighting its potential to optimize processes traditionally performed manually and susceptible to inconsistencies. Thus, the present case study aimed to evaluate the application of BIM 5D for cost estimation in a residential project. To this end, a preliminary analysis and the necessary adjustments to the models from the different disciplines were carried out, followed by project coordination in a federated environment and the correction of the identified incompatibilities. Subsequently, the Work Breakdown Structure (WBS) was developed, and the project budget was prepared, with the quantities extracted from the model linked to their respective cost compositions. The results demonstrated that the prior review of the models and the project coordination process were essential to ensure the consistency of the information and the reliability of the extracted quantities, contributing to greater accuracy in budget preparation. It is concluded, however, that although BIM 5D has great potential to make the budgeting process more automated and traceable, its implementation should be evaluated according to the complexity and particularities of each project, considering the maturity of the modeling process and the technical training of the teams involved.
