Utilização de um modelo BIM 5D para orçamentação: um estudo de caso

Abstract

The downturn in the construction market in Brazil encouraged companies in the industry to change their executive processes, raising interest in technologies that may result in better management and lower costs of the projects. Building Information Modeling (BIM) technology stands out for its great potential for optimizing various construction-related activities, as it allows buildings to be built virtually before their execution occurs. By using the BIM 5D model the extraction of quantitative data can be automated, reducing the chances of errors and omissions and resulting in a more accurate and reliable estimate. This work aims to create a BIM 5D model through a case study. For this, all the projects of a residence were modeled through BIM technology and later a schedule and a estimate cost for the same were elaborated. To estimates the costs was used the plug-in for Revit OrçaBIM, created by the company Orçafascio. The performance of all the software used was satisfactory for the creation of the 5D model and OrçaBIM was able to automate the quantitative survey process, bringing credence to the estimator and agility to the estimating process, resulting in a precise estimate, provided there is a previous modeling appropriate to the process. However, this program does not have an automated link with the elaborated schedule, and therefore part of the process of elaboration of the BIM 5D model still had to be performed manually.
