Influência da metodologia BIM na orçamentação de projetos de instalações prediais: um estudo de caso de uma obra pública no município de Boa Ventura-PB.

Abstract

With technological advances and the expansion of civil construction, new concepts and tools emerge as alternatives to improve the quality of works, seeking more favorable results. A prominent technology is Building Information Modeling (BIM) which provides for the identification of project incompatibilities and faster budgeting. In this way, the present study aims to verify the applicability of the BIM methodology in the elaboration of projects of electrical and hydrosanitary installations of a Basic Health Unit - UBS, in the city of Boa Ventura - PB. To achieve the proposed objective, the original 2D projects were analyzed and modeled in 3D using Revit software. With the 3D models, the interference between the projects was verified and the automatic extraction of the quantitative was carried out for the preparation of the budget. The use of BIM resulted in the prior identification of interferences, enabling the correction of 141 conflicts between constructive elements. The automatic survey of quantities accelerated the process of preparing the budget of the building facilities, with a slight increase of 0.11% with the use of Revit in the total cost of the work. It is concluded with the study that the BIM methodology is capable of adding benefits in the elaboration of projects of building installations, providing graphic visualization of a virtual model of the work, identification of project interferences before execution and automatic extraction of quantitative, streamlining the process of budget preparation.
