Análise da contribuição da modelagem BIM na construção civil: estudo de caso em uma obra de grande porte

Abstract

Civil Construction is an area of Engineering that constantly goes through changing processes, which seeks to improve in both design and building methods. In this context, the use of a new methodology for modelling, storing and analyzing the model, named BIM or Building Information Modeling, has been gaining strength. Hence, the objective of this research is to contribute to a better understanding of the benefits provided by the BIM methodology in the design project and execution of significant works in Civil Construction. The method used was the Case Study of a large building located in Fortaleza - CE, named BS Design. The research was gathered through interviews, questionnaires, on-site observation and collection of materials. In the data analysis and interpretation stage of the study, the previous step was clarified along with the development of the research in four isolated sections. The first one investigated the benefits of the 3D visualization process. The second verified the facilities and contributions generated by the use of BIM at the construction site. The third section was the calculation of the saved value with the use of BIM for clash detection. Lastly, the fourth check the operation and advantages of using the BIM 4D in the construction of the metal structure. Therefore, the explicit analysis identifies how this technology contributes on the solution of problems that often happens in the construction industry, such as rework, materials waste, difficulty to find information and to communicate among designers. The importance of this technology for the constructor as well as for the designers was enhanced since 3D modelling completes the design phase and allows the perfect understanding of each constructive step in an efficient way. It is also worth regarding that this technology is even more relevant when it is taken to the construction site through mobile devices, inasmuch as the complete digital model allows a great use of the information of the BIM model. Also, it was verified that the saved value by the clash detection between the installations and the metal structure on BS Design was significant. Finally, BIM 4D study revealed the relation between the construction evolution over time and the possibility of interaction with the construction site in all stages of construction, positively impacting the construction planning.
