With the increase in activities in the construction industry, one of the sectors that consumes the most natural resources and generates the greatest environmental impacts, there has been a growing need to seek more sustainable construction methods. In this pursuit, one way to promote better resource use is to ensure that processes do not need to be redone, i.e., to avoid rework. The present study proposed a case study aimed at measuring rework, analyzing its impacts, and defining corrective actions in a construction project. A total of 34 rework incidents and their 486 occurrences were analyzed for the stages of sealing, installation and finishing. Rework activities were mainly generated by failures in planning, scheduling, engineering, and supervision. These situations resulted in an additional cost of approximately 301,000 reais for the project. Based on the findings, a checklist was created that included preventive and corrective measures to reduce rework activities, with actions to be implemented such as allowing more planning time before the execution of activities, ensuring more assertive communication between engineering and suppliers, and training employees whenever there is a change in sector.
