Avaliação da execução dos sistemas prediais hidrossanitários em edificações residenciais de médio porte

Abstract

The building systems of a building must be executed in such a way as to follow the performance criteria indicated in the technical standards, guaranteeing the user comfort and safety and avoiding the emergence of pathological manifestations, which are so common in this type of system. Therefore, the present work aims to evaluate the execution of building hydrosanitary systems in medium-sized residences, identifying the main errors that favor the appearance of pathological manifestations in these systems. To collect and analyze the data, case studies were carried out with three medium-sized residential buildings. Through field observations, document collection and interviews, we sought to understand the executive procedures adopted for drinking water supply and sanitary sewage installations, making it possible to identify the main errors associated with such systems in relation to the execution stage. As main results, it was identified that the three works had construction errors associated with the storage processes of materials and components. Next, in relation to the analysis of the execution of the water supply subsystem, it was observed that the buildings had problems related to protection measures, identification and verification of the pipes. Finally, during the installation of sanitary sewage, errors were identified associated with laying the trenches and the protection, fixing and verification processes of the components. Finally, some pathological manifestations have been associated with these errors. By identifying these failures, most of which are recurring, this study contributes scientifically and technically to the study of the implementation of building hydrosanitary systems in medium-sized residential buildings, providing information that expands understanding of the topic and offers a basis for future work that may suggest and implement improvements and interventions in the executive processes of these systems in buildings of this type.
