Modelagem BIM para estimativa da geração de resíduos da construção civil: estudo de caso

Abstract

Construction waste represents a significant portion of the solid waste generated in the country, and this amount continues to grow without effective management, with irregular disposal being one of the main problems faced in most of Brazil. Studies indicate that the use of Building Information Modeling (BIM) in the design and planning of projects can be an effective tool for reducing the amount of waste generated, as these wastes are predominantly produced by errors and unexpected changes during the design and construction phases. Therefore, the primary objective of this research is to evaluate the application of BIM modeling in the generation of construction waste during the project design phase. The research quantifies, through BIM modeling, the elements used in the project design and estimates the rate of waste generation during construction based on the obtained data. Additionally, it develops a waste management plan for the analyzed project, using the obtained quantities to estimate the amount of waste to be generated, characterizing it in a way that facilitates proper final disposal. This research contributes to the use of BIM modeling in the waste management market by enabling, through an existing estimation model, the prediction of the amount of waste generated during the construction phase. This allows for greater project control and aids in the development of the management plan, enabling construction companies to identify waste categories, determine the most significant types of waste flows, trace their origins, and estimate the necessary amount of stationary dumpsters. For future research, it is recommended to develop a tool capable of automatically estimating the waste generation rate based on the quantity takeoff tables generated by Revit software, making the process of waste characterization in the waste management plan more agile, efficient, and reliable.
