Análise de evidências patológicas na fase de pós-obra em edificações multifamiliares : um estudo de caso

Abstract

Technical assistance plays a fundamental role in collecting valuable data for the continuous improvement of construction processes. By analyzing this information and maintaining rigorous control over each stage of construction, it is possible to enhance work methods, material quality, project adjustments, and provide training to employees. However, even after adopting all measures to ensure quality, the construction company may still face failures after delivery to the client. Pathological manifestations in buildings are problems, defects, or failures that compromise their functionality, safety, and aesthetics. Common causes include design errors, execution failures, lack of proper maintenance, use of inadequate materials, and climate variations. To mitigate these effects, companies seek to implement a quality management system. Such a system aims at customer satisfaction and continuous improvement of organizational procedures. The concept of quality, though variable depending on the context, converges towards service excellence and customer satisfaction. Therefore, this study aimed to analyze the pathological evidence that emerged after the delivery of the developments. To this end, a case study was conducted on two multifamily developments. The results show that a significant percentage of pathological manifestations were detected in the hydrosanitary systems (20.41%), frames (14.80%), and masonry (12.24%). Furthermore, it is noticeable that a high percentage of these anomalies were caused by execution errors.
