Rework has become an endemic feature of construction projects and yet factors that influence its occurrence remain an enigma. Using a structured questionnaire survey, the causes and costs of rework in 161 Australian construction projects were identified. Respondents were invited to indicate direct and indirect rework costs that would be subsequently combined to produce a total rework cost figure. Stepwise linear multiple regression analysis was then used to determine those significant variables that contributed or lead to a reduction in total rework costs for the projects sampled. Client initiated changes and ineffective use of information technology by the design professionals were identified as being significant variables contributing to rework occurrence. Contrary to a priori presupposition, design scope freezing was also identified as being a significant factor that can contribute to rework.
