Rework occurs across the life cycle of projects and has significant impacts on construction project performance. A rational approach to managing rework is by identifying the main sources of rework; then mitigation measures can be implemented to enhance performance on projects. Rework has been widely studied within the construction industry, but the link between rework and contract conditions remain unexplored. This study identifies and classifies the root causes of rework at the construction stage of projects. It then examines the relationship between the conditions of contracts with the identified root causes. A comprehensive list of rework root causes was determined through the review of literature, which was categorized into five classified factors. The classified factors include process, human resource, material/equipment, technical, and other related environmental and financial factors. The next step comprises a questionnaire survey designed to determine relationships between rework and contracts. The result of the study is presented descriptively for ease of understanding. The results show that rework could be managed more efficiently through contracting processes, which ultimately benefits construction projects’ performance.
