O impacto do controle de qualidade no custo total da obra: estudo de caso da manutenção pós-obra em Curitiba

Abstract

In a context in which market competition is increasingly intense, the best way for a company to guarantee its survival is by satisfying its customers’ needs, a fundamental principle of quality management systems. The civil construction sector, as well as other productive sectors, began to adapt to the principles of quality and productivity management in the search for cost reduction and, therefore, it was necessary that processes and materials were improved, reducing waste and failures. This work aims to analyze the financial impact of rework in a building work due to the lack of a quality control system to prevent failures. To carry out the research, the costs were calculated and the main problems analyzed. To obtain this comparison, a case study was carried out in a building located in the city of Curitiba-PR. Data on complaints from residents of the services were collected and the costs of these visits and the necessary materials were calculated. It was found that the costs used in maintenance without quality control can have significant values in the total cost of the work. To improve the quality management of the case study construction company, the tools of the quality management system must be implemented and adopted in their work processes.
