O método BIM e o controle orçamentário: uma análise crítica da relação planejamento, gestão e orçamentação

Abstract

In the midst of high demands and the search for greater productivity, the BIM method, as an efficient production system, arrives to open doors in the civil construction sector, mainly in the scope of budget planning. However, it is not the final solution for all existing problems, some problems that need to be studied and improved and are often camouflaged by the advances achieved. In this sense, the present work is an exploratory study, carried out through a bibliographical research with the objective of analyzing the participation of the 5D BIM method in the budget planning and to identify possible causes for still existing problems in the connection between planning, management and budgeting. For this, research was carried out for the theoretical basis on the subject, understanding the budget planning, the new methodology and its needs. A survey of case studies by several authors was also carried out, which present the extraction of quantitative and costs of BIM platforms and make comparisons with traditional methods and even with real cost of work, and chosen four main ones to be analyzed, finding critical points in common and solutions for a more efficient system. It was observed that the main causes of existing problems, even with the use of the methodology, were in the export and identification of information for element modeling and quantitative extraction, proposing improvements such as improvement in communication between collaborators for a better integration of information, creation of component libraries, standardized budget bases (unit costs), as well as the use of the IFC language only for reading, without permission to modify files.
