Modelagem BIM 4D de uma residência unifamiliar de padrão alto: estudo de caso

Abstract

Building Information Modeling technology is an intelligent way to create models that contain multidisciplinary information. This technology enables all information created or collected about a building to be accessed by all agents involved in any stage of construction. There are several BIM tools that can be employed in different disciplines, and their data can be stored and integrated. This data integration allows incompatibilities in project modeling to be detected. There are several BIM modeling dimensions, which provide information on different aspects of planning and construction control. In the 3D dimension the authoring modeling of the project is carried out, that is, the creation and initial visualization of each discipline. The 4D dimension is obtained by including in the model the data referring to the construction schedule, which allows the simulation of the construction stages. The present work aimed to perform the 4D BIM modeling of a single-family residence with 337.24 m2 of built area, with the help of computational tools that use BIM technology. To do so, initially, the 3D computer modeling of the infrastructure elements and superstructures, electrical and plumbing installations was done. Next, design incompatibilities were detected and the execution schedule was linked to the 3D model (4D dimension). Through the 4D modeling it was possible to forecast the project's execution time and visualize the construction sequence of the virtual model.
