Análise das não-conformidades na gestão da qualidade de canteiros de obras verticais: impactos e estratégias para prevenção de manifestações na fase de pós-obra

Abstract

From the tripod of cost, time, and quality, which is emphatically addressed in studies involving construction sites, the third element is what determines the best way to optimize the others. Considering this perspective, the present work aimed to study quality management on construction sites of vertical residential buildings in the city of João Pessoa - PB, focusing on analyzing the actions taken regarding the handling of non-conformities during the construction and post-construction phases of the projects. By examining records of non-conformities and collecting opinions through questionnaires from managers, workers, and users of two projects belonging to the same construction company, information was gathered that contributed to understanding the effectiveness of the Quality Management System, the company's operational methods for treating non-conformities, and how the data generated during the construction phase is utilized in the use and maintenance of the buildings. The main results demonstrated a substantial implementation of the quality system within the company’s processes; however, the significant occurrence of non-conformities, low frequency of audits, and lack of planning and communication with owners regarding post-construction prevention strategies indicate a need for improvements to be made to this system. Based on these findings, recommendations, to be validated in future projects, were made, aiming to reduce the occurrences of non-conformities and optimize the maintenance processes of the buildings, through increased training for workers and quality audits during the execution phase, as well as the use and provision of non conformity records to owners in the post-construction stage, enhancing the relationship between the construction company and the client, thereby increasing client satisfaction and strengthening the company’s image.
