While several studies have identified key factors that contribute to rework costs, the aim of this graduation project is to pinpoint the major contributors to rework costs through a survey-based questionnaire method. Additionally, the construction sector's impact on the environment and natural resource consumption is substantial, with significant energy use during construction and operation. Rework exacerbates these issues by generating additional waste and increasing resource use.
