A utilização do processo BIM na elaboração de orçamentos de obras de construção civil

Abstract

Building Information Modeling (BIM) or modeling of the construction information is a process that proposes the integration of the different disciplines involved in the project in a single model, thus seeking to create a new data sharing level. Among the data to be incorporated into the model are the costs of construction. The use of the integrated model, in preparing the budget, want to minimize some common mistakes, especially regarding the quantitative survey. Several BIM tools allow the inclusion of information related to the construction costs, in order to facilitate and improve the budgeting work. This study was initially conducted an analysis of the traditional budget process through literature. In the face of difficulties and failures of the current process were analyzed tools available that allow integration between budget and the BIM model, and then select those that best supriam the raised requirements. This choice was based on information in the theoretical framework and previous use of the tools in a trial stage. They were then applied three methods of integration between the budget and the BIM model, in order to make a comparative analysis of the processes, checking also that the differences in the form of traditional budgeting. As a result, it can be noted that the use of this model enables better management of the cost information, especially with regard to quantitative. also allowing easier absorption of design changes and technical alternatives study.
