Estudo de caso: aplicação da modelagem BIM para extração dos quantitativos de obra de pequeno porte – análise do custo estimado e custo real

Abstract

This work presents the application of the BIM (Building Information Modeling) methodology in a case study of a small residential project, analyzing its threedimensional modeling predictions in the design of projects in an integrated way and its incompatibilities, the quantification and costs of building materials construction and creation of work schedules. The reason for carrying out this work was considered to be the difficulty of integrating projects and designers in a 2D form with independent projects (such as projects on a CAD platform – “Computer Aided Design”) and the greater complexity of current projects, causing a high rate of unforeseen events, rework, delay in execution and waste of materials on site. The work addresses a way of developing and organizing a BIM project using specialized software, from its configuration to its application in the case study, which went through a long phase of testing and studies, as it requires specific knowledge in its operability, and find the best way to remove the necessary data in a simple and efficient way. The results of this research demonstrate that the application of the BIM methodology in a case study of a small residential project provided significant benefits. The study explored the different dimensions and maturity levels of BIM. Even for small projects, the BIM methodology speeds up the budgeting process, highlighting its benefits.
