Projeto de instalações sanitárias prediais com o uso da tecnologia Building Information Modeling (BIM)

Abstract

The use of the Building Information Modeling (BIM) methodology has promoted significant advances in the development of construction projects by providing greater integration among disciplines, reducing design inconsistencies, and automating engineering processes. This study developed the sanitary drainage system design for a multifamily residential building in a BIM environment using Autodesk Revit® 2025 and the design criteria established by ABNT NBR 8160:1999. The adopted methodology included building characterization, analysis of the architectural design, three-dimensional modeling of the sanitary drainage system, sizing of branch drains, horizontal drainage branches, soil stacks, building drains, building sewer collector, and venting system, coordination with the architectural and structural projects, preparation of technical documentation, and automated material quantity takeoff. As a result, an integrated digital model was produced, containing all the information required for project detailing, including plans, sections, isometric views, and quantity schedules. The BIM methodology enabled greater accuracy in project development, automatic updating of technical documentation, early identification of clashes between disciplines, and improved reliability of material quantity extraction. It was concluded that the application of BIM contributed to improving project quality, reducing rework, optimizing the coordination process, and enhancing the management of technical information, demonstrating its relevance to the development of sanitary plumbing system projects.
