Avaliação quali-quantitativa de não conformidades na etapa de acabamento de uma obra na cidade de Goiânia/GO

Abstract

Quality Management plays a fundamental role in preventing failures, reducing waste, and promoting continuous improvement in construction processes. In this context, tools such as Service Execution Procedures (SEP) and Service Inspection Forms (SIF) support quality control and the identification of nonconformities that may lead to rework, additional costs, and project delays. Therefore, this study aimed to identify and analyze the main nonconformities observed during the finishing phase of a multifamily residential building project located in Goiânia, Goiás, Brazil, as well as to propose improvement opportunities for the company's Quality Management System (QMS). To achieve this objective, inspections were conducted in 80 housing units, resulting in a total of 667 recorded occurrences. The data were organized and prioritized using the Pareto Diagram and subsequently analyzed through Ishikawa Diagrams developed from field observations, Service Inspection Forms (SIF), and Service Execution Procedures (SEP). The results showed that more than 80% of the occurrences were concentrated in finishing and gypsum board services. Among the prioritized nonconformities were hollow-sounding floor tiles, inadequate floor slope toward drains, missing electrical wiring routing, and clogged drains. The analyses indicated that a significant portion of these occurrences was associated with deficiencies in execution procedures, limitations in quality control mechanisms, and incompatibilities between design solutions and execution requirements. It was concluded that the integrated application of quality management tools enabled the identification of the main causes of rework observed in the project, providing support for improvements in execution procedures, inspection controls, workforce training, and service coordination, thereby contributing to the continuous improvement of the construction process.
