  • Abstract:
    Construction management engineers are often faced with projects containing multiple units wherein activities repeat from unit to another. The repetitive activities, which can be seen clearly in multi-storey buildings, require schedules that ensure the uninterrupted usage of resources for an activity in one unit to a similar activity in the next unit. The repetitive and non-repetitive scheduling model described in this paper recognizes the constraints between the activities and includes also an additional resource continuity constraint to ensure continuous resource usage. It's applied to both vertical and horizontal projects containing either discrete or continuous activities. The scenarios stocked in the model will generate automatically the majority of these constraints and therefore the validation point between two successive activities is located and checked. For each activity the model validates the constraints with the precedent activities. The decision of the early time date of the sequence activity is taken when all the constraints are satisfied. The planning of the whole project can finally be obtained.
