Uso da metodologia BIM na orçamentação de projetos hidrossanitário e elétrico

Abstract

Brazil's construction industry is going through a period of crisis, causing companies to find ways to cut costs and increase productivity. In this context, BIM (Building Information Modeling) methodology emerges as an alternative in order to contribute to increased reliability and productivity in budgeting. Traditionally, the process of material quantification has in most cases been non-integrated. In general, the adopted is the extraction of quantitative models, which are added in spreadsheets that are disassociated from this model. This process is subject to human error and tends to propagate inaccuracies. Similarly, quantification is also time consuming and may require 50% to 80% of the time to estimate a project's cost. With BIM, quantitative extraction can be automated, minimizing the chance of errors, resulting in a more accurate and reliable budget. This work aims to use the BIM technology for modeling and obtaining quantitative of complementary projects of a single-family residential and subsequently budgeting these projects. For budgeting, the Revit OrçaBIM plugin, developed by OrçaFascio, was used. The method of extraction of quantitative evaluated was satisfactory, since it was obtained a fast and precise quantification of the materials used, and the integration with OrçaBIM provided agility in the process of budgeting.
