Avaliação do sistema de gestão da qualidade em uma construtora: análise por meio de auditorias internas

Abstract

Quality management in the construction industry faces significant challenges related to process standardization, variations in construction site performance, and the effective application of procedures established by the Quality Management System (QMS). Although standards such as ISO 9001 provide structured guidelines, their practical implementation is not always homogeneous across different projects of the same company. This study aims to evaluate the applicability of the QMS in a medium-sized construction company through a comparative analysis of the results of internal audits conducted on the three most recently completed projects. The research adopts a qualitative approach, combining the documentary evaluation of audit reports with semi-structured interviews conducted with the technical managers responsible for this management in each project and those called for post-construction technical assistance. The results showed significant differences in the level of adherence to the QMS among the analyzed projects, even though they were subject to the same corporate procedures. It was observed that the main variations in performance were associated with operational factors such as workforce turnover, the level of experience of the technical team, site organization, and the regularity of records and controls. Among the recurring difficulties, failures in document updates, communication between sectors, and handling of non-conformities stood out, indicating gaps between formalized procedures and their practical application. These findings allow us to understand the factors that influence the effectiveness of the QMS in the field and offer support for improving quality management practices on construction sites.
