Utilização da modelagem BIM 4D e 5D no planejamento e orçamento de uma edificação unifamiliar

Abstract

The increase in competitiveness in the civil construction market and the search for cost reduction have led companies in the field to seek new technologies and methodologies capable of reducing waste and optimizing processes during the elaboration of their products. In this context, the Building Information Modeling (BIM) methodology offers features that optimize the project creation process, since its three-dimensional visualization allows the creation of an electronic model of the project, enabling the compatibility between the disciplines from modeling to the automatic creation of views and sections from these objects, in addition to allowing the storage of information pertinent to each object and its construction stage. Adding cost and duration information to the modeling process, we have a model capable of providing valuable data from the design phase of a project, called 4D and 5D BIM models. This work aims to demonstrate the creation of a BIM model, inserting information that facilitates the budgeting and planning process of the project. For this, the disciplines of a single-family house were modeled already compatible through links, with the help of the Revit software, soon after, the Navisworks software was used to detect any conflict between objects that was not detected during the modeling, inserting all the disciplines, creating the federated model. To prepare the schedule, the Agilean Planner software was used, to generate greater ease in the manipulation of activities. In addition to the Revit software, the OrçaBIM plugin of the Orçafascio platform was used to extract quantities, budget, and compatibility of the contingent necessary to meet the deadlines of the schedule. Finally, the schedule was exported from the Agilean Planner software to the Navisworks software, for the creation of the constructive simulation from the federated model. The performance of the methodology and its tools used for the development of the process and creation of the projects was satisfactory, providing a 3D, 4D, and 5D view, even in the initial phases of the project's conception, generating important data in this phase, making the construction process more predictable and controllable.
