The civil construction sector has great economic impact on Brazilian economy and is responsible for employing a large portion of Brazilian workers. However, it is defined as a cyclical economic activity, which presents moments of high or low development according to the national economic scenario. This industry still applies many obsolete design procedures and processes, an example is the use of CAD technologies for designing. Thus, BIM, an acronym for Building Information Modeling, is a prominence methodology among professionals in this economic sector and its implementation may result in gains in a sector that is resistant to adopt technological innovations. This academic work aims to develop a case study based on a multifamily building 3D model through the use of the software Revit. This study was made possible by the parallel work of a local construction company that used a traditional design methodology to obtain the construction cost estimate. In addition, this academic work was based on the application of the 5D cost estimate methodology, through a plug-in called OrçaBIM, in order to compare the cost estimate process in BIM with the usual cost estimate process, which is practiced by the construction company. The application of this research methodology resulted in a quantitative survey that was compared to the original quantitative. In conclusion, the application of the BIM methodology in the projects of this study presented several benefits in relation to the CAD projects, such as quantitative survey and synchronization between BIM model and cost estimate.
