Rework in construction is inevitable. It has a direct impact on the cost and the time of the project. Therefore, finding the factors that lead to rework can help control the extra cost and time as well as preventing from design problems among architects, construction engineers, contractors and users. In this study, twenty factors that lead to rework have been extracted from previous research. After examining the output data from factor analysis, the factors affecting rework have been divided into four variable groups: Project management, Education, Changes and Interaction with the environment (Immersion). Lack of understanding of the project model by the designer, contractor and user is one of the direct consequences of “Changes,” “Education” and Interaction with the environment that affect rework. A virtual environment, using virtual reality, has been proposed on a one-to-one scale where the users can be immersed in the environment; this virtual model helps better understand the project at the design stage.
