O Papel da qualidade na redução de retrabalhos: um estudo de caso em uma obra com estrutura de parede de concreto armado

Abstract

This study aims to analyze the role of quality in reducing rework in construction projects involving reinforced concrete wall structures, through the application of consolidated quality management practices in a real construction site. The study is structured in stages that encompass the theoretical contextualization of quality principles, the applicable regulatory systems (ISO 9001, PBQP-H, and SGQ), the operation of the PDCA cycle, and technical aspects of the concrete wall construction system, including formwork, reinforcement, and concreting. The adopted methodology consisted of qualitative and applied research, with a case study of a large-scale residential housing project, using direct observation, document analysis, and a semi-structured interview with the engineer responsible for quality and post-delivery of the project. The collected data demonstrated that the systematic application of the Quality Management System (QMS), through standardized procedures, digital Service Verification Sheets (SVS), and the use of monitoring tools such as Power BI, has a direct impact on mitigating failures, increasing productivity efficiency, and enhancing information traceability. It is concluded that quality, when integrated as an organizational culture and operationalized based on data and planning, is a strategic element for reducing rework and improving the overall performance of projects executed with the cast-in-place concrete wall system.
