CPM scheduling has been with us since the late 1950s and has demonstrated renlarkable resilience since that time, and the basic algorithms remain substantially unchanged to this day. "While there has been a great deal of focus on the mallagelllent of resources using CPM) there has remained a sense of dissatisfaction with the method for managing construction work. Many authors have suggested that an alternative nlethod should be sought which addresses the flow of resources on a construction project This paper argues that CPM is an activity-based methodology and COlupares it with an alternative locationbased methodology) which includes location-based luethods of greater lineage such as line-of-balance and the proposed flowline. The case for improved management of resources is argued using a sinlple fitout project. It is concluded that the CPM engine should remain, but that additional layers of complexity should be introduced to achieve a location-based CPM model.
