Análise comparativa entre orçamento BIM 5D e orçamento tradicional: um estudo de caso do Empreendimento Junção

Abstract

The survey of the work quantities is a very important step for the success of the civil construction projects, contributing to the planning of the construction stages, to the need for funds in each phase of the work and to the correct measurement of the inputs used. It is common for the quantity to go through a lot of inaccuracy when raised manually. BIM - Building Information Modeling - is seen as a concept that revolutionizes not only the way of designing and defining the quantities of materials used in a work, as well as the presentation of the project to the client, facilitating the understanding of the construction as a whole. The technology has been adopted worldwide by the AEC sector - Architecture, Engineering and Construction - due to its numerous advantages for the design, documentation, execution, operation, renovation and demolition, dealing with the entire life cycle of a building. The objective of the work is to analyze the use of this new technology for the extraction of quantitative, comparing the results with the traditional way of surveying materials. The method used to carry out this work consists of a comparative analysis of a real work carried out in the city of Rio Grande, with a parametric model constructed virtually based on the projects of the same work. The software used to develop this work was Autodesk Revit and Orçafascio, both in educational version. The results elucidate the advantages and disadvantages in the use of BIM for project and construction monitoring, the difficulties faced to model the building and conclusions about the need to adopt a clear Project process in an enterprise, where the project and the budget talk to each other.
