ABSTRACT Construction scheduling is usually limited to the documentation of one final construction schedule, and construction alternatives that might have been considered during the planning process are usually not included in the final schedule. Moreover, a formal control of construction schedules in terms of completeness and correctness is very limited, because existing methods, such as 4D visualization, are insufficiently integrated into the construction planning process. This paper addresses the development of a software framework that has been designed to support the process of construction scheduling. As will be shown in this paper, the process of construction scheduling, which is usually carried out manually, is conducted automatically to a large extent using building information models (BIM) and 4D visualization. Due to the logical interconnections of BIM objects and construction tasks, flexible schedules and visual representations of construction processes are automatically generated without permanent human interaction
