EXERCÍCIOS DE AUTOMAÇÃO PARA ORÇAMENTAÇÃO DE OBRAS ATRAVÉS DA FERRAMENTA BIM

Abstract

Civil construction is highly based on obsolete and inefficient processes, from planning to execution, making constructions more protracted and expensive. To minimize some of these problems, BIM (Building Information Modeling) technology has become a great ally, since it is possible to simulate and improve the construction process from the initial phase of the project, through planning, budgeting and execution of the project. This work presents BIM tool use in a Retrofit, with the aim of evaluating the automation of the construction budget and analyzing the quality and efficiency of the method of extracting information from the parametric model. Based on that idea, three exercises were developed at different levels of complexity, and then, three exercises were developed at different levels of complexity, and the programs used for the exercises preparation were Revit – for modeling and extracting quantitative spreadsheets, the Dynamo – to export the spreadsheet to Excel where the data was formatted and related to the SINAPI table. It was detected during the modeling and budgeting processes that the BIM platform is able of automating this important step of construction planning with great efficiency and precision; but two points must be improved in this process: the control of the numerous tools used, which are quite complex, and the interoperability of the programs involved in the extensions, versions and interactivity issues between them.
