Implementing the Quality Management System (QMS) has the following principles: improve the construction processes, reduce production costs, minimize rework, increase productivity, and, consequently, increase profitability and satisfy customers by delivering a quality product. Based on this assumption, the study looks at how the implementation of the QMS affects the post-work, which is justified by the standardization and mastery of procedures by monitoring potential errors that can lead to pathological manifestations. In this context, this study analyzed the findings of the internal and external audits performed during the execution of two developments of collective housing units, executed in the cities of Goiânia and Aparecida de Goiânia, to identify correlations between them and the pathological manifestations identified in the post-construction inspections. The case study and data survey were the methods used. It should be noted that the two surveyed buildings were built with the same construction method. Regarding the audit results, Enterprise A registered 22 more non-conformities (NC) than Enterprise B. During the post-construction phase, Enterprise A was the most compromised with the incidence of pathological manifestations, with 67 more occurrences than Enterprise B.
