Análise da compatibilidade de projetos utilizando a tecnologia BIM como medida de análise de custos na execução de projetos elétricos e hidrossanitários: estudo de caso

Abstract

Civil construction in Brazil has been undergoing a rapid transformation process, as a result of the demand for new housing and the improvement of the country's infrastructure. As a result, new technologies, such as Building Information Modeling (BIM), has been developed, which uses technology to develop precise virtual models of a building that provide benefits such as automatic identification of interferences, 3D modeling and automatic extraction of quantities. This work aimed to analyze the financial impact generated in electrical and hydrosanitary projects from the compatibility of projects in BIM. Such analysis was based on the case study of a single-family residence developed in CAD and its projects: architectural, structural, electrical and hydraulic were modeled in BIM technology, in addition, in this compatible aspect. After the compatibility, conflicts of the electrical and hydrosanitary projects were changed and, from this, the automatic quantitative generation of the projects with and without compatibility was carried out and soon after, the cost analysis was carried out to analyze the impact of the compatibility in BIM in installation projects. It was noted that there was a reduction of 0.22% in the general cost of electrical installations and an increase of 3.08% in the general budget of hydrosanitary installations. It has been understood that the financial impact generated by project compatibility for small installation projects does not provide a wide difference in financial terms. However, the compatibility of projects in BIM proves to be the most effective within this segment and in other BIM practices such as parametric modeling and automatic extraction of quantities, facilitating processes for future steps such as budgeting and construction planning.
