Summary Cost management includes planning and control, and constructability1 and prefabrication construction are two main design economics factors for early cost planning decision. Despite the fact that constructability and prefabrication have been considered in design and cost planning, there is no guarantee if the intention meets the expectation. This requires on-going control during construction stage. In fact, prefabrication construction has been encouraged for some years, application is not always positive. One of the reasons is its constructability. This paper investigates the appropriate research methodology to determine how design for prefabrication and constructability will contribute to cost planning through control and review during construction stage. Through a study of an Australian residential project using prefabrication in structural concrete, internal partitioning and internal fit-out, this research concludes that case study is a viable choice. Prefabrication construction does provide a positive impact on the major project objectives: time, cost and quality. Cost reduction is due to saving in time related preliminaries as a direct result of time reduction of onsite activities whilst quality is ensured due to better control of prefabricated components inside the factories. However, it can only be achieved after considering constructability: suitable materials choice, design for available skills, use of available plant, and clear communication. The keys are through plan at design phase and control in construction stage.
