Metodologia BIM aplicada no orçamento de obras – Revisão de literatura

Abstract

The budget is one of the most important stages for the construction of an enterprise, because it is through it that it becomes possible to assess the economic viability of the work. The use of different methodologies and incompatibilities throughout the life cycle of a project can cause inaccuracies and negative impacts on the budget analysis. Thus, budgeting implementation in BIM (5D BIM) can offer opportunities to improve the quality, speed and accuracy of project costs. In this study, we sought to present, through a bibliographic review, fundamental concepts for understanding the BIM methodology interface and construction budget. For the bibliographical review, articles, dissertations, theses, congress proceedings, books and documents that address the characteristics of BIM, the maturity of this technology in Brazil and in the world, its use in the budgeting process, as well as the advantages and disadvantages were selected. of its use in this process, in addition to the tools compatible with BIM 5D. It can be seen that the implementation of BIM optimizes the budgeting process, especially in the quantification phase, extracted directly from the model, generating more precision and, consequently, reducing error margins. In addition, the use of BIM provides agile budgeting, allowing the estimator to act strategically by exploring different construction scenarios, gaining more time to analyze and predict expenses that could be reduced, in addition to reducing delivery time, which will impact the project. However, it is important that the models are well developed and that there is integration, communication and collaboration between the professionals involved in the project, avoiding incompatibilities and difficulties in the budgeting process.
