Construction projects are complex in nature because they entail complex activities characterized with uncertainties and changes that are capable of increasing time and cost of construction projects. Rework is a waste that involves doing certain task more than once, it may not be totally eliminated but it is avoidable. It occurs as a result of so many factors ranging from omission or error in design, construction failure, and change order to inadequate coordination and communication among stakeholders on the project. Hence, to enhance project performance it becomes imperative to identify the influence of project type on the occurrence of rework. This paper presents analyses and discusses the rework costs experienced by the studied projects and the findings revealed that the cost of rework for new buildings understudied was averagely 5.06% as against 3.23% recorded by refurbished buildings of the completion cost. Therefore, to improve project performance and to reduce the menace of rework costs, it is asserted there is need for consensus to be reached on a workable mechanism to bring together the client and the contractor to minimize change orders and introduction of additional works during construction phase.
Key words: Rework, project type, expanding economy, building projects.
