Study on Systematization of Construction Scheduling Method Structure of Construction Scheduling and its Constitute Systems

Based on our experience, an emphasis in construction scheduling is not always same. Then we surveyed various opinions of construction engineers about construction scheduling. As a result it was clarified that methods of construction scheduling were different in each phase of projects and each type of projects. We classified construction phase into pre-execution stage, execution stage and post-execution stage, and construction type into ordinary method construction, construction in which adopted new method such as roof push-up method, large-scale construction and peculiar construction (PCa construction etc.). Further, we arranged examination contents in construction scheduling into the matrix composed of each phase and type. The other hand many types of computer- aided construction scheduling systems have been developed, and some of them are now in wide-spread use. However because of the wide variety of construction projects and it is not necessarily said that those systems can be used effective for every project. This paper examines the needs for construction scheduling in various stages of many types of construction projects, discusses the structure of construction scheduling method, and introduces the outline of three systems developed based on this structure.
