Activities that repeat from unit to unit create a very important need for a construction schedule that facilitates the uninterrupted flow of resources (i.e., work crews) from one unit to the next, because it is often this requirement that establishes activity starting times and determines the overall project duration. Hence, uninterrupted resource utilization becomes an extremely important issue. The scheduling problem posed by multiunit projects with repeating activities is akin to the minimization of the project duration subject to resource continuity constraints as well as technical precedence constraints. The uninterrupted deployment of resources is not a problem addressed by the critical path method (CPM), nor by its resource-oriented extensions, such as time-cost trade-off, limited resource allocation, and resource leveling (Robert and Photios, 1998).
