Controversies over that the scheduling practices for the construction projects in Korea are unsystematic, illogical, and less advanced still continue. One of the main controversial issues is that the existing scheduling techniques does not satisfy the scheduling requirements of construction site. Because most construction personnel prefer a good-looking and easy understanding schedule, LOB and TACT techniques although those are not formal CPM technique have been applying overwhelmingly in the construction projects. Moreover, LOB and TACT techniques can be quickly and conveniently established by Excel or word-processor familiar with most people. Since Excel is not a formal scheduling software, however, it can not provide formal CPM scheduling practices. The purpose of this study is to propose the method that can satisfy visual schedule format as well as perform formal CPM scheduling practices by integration of LOB and TACT techniques by BDM technique.
