| Abstract |
Top-down method is divided into Up-down method which is digging underground from earth level and making underground structure and slab at the same time and Double-up method, advanced technology compared to Up-down, which is making underground structure and ground structure coincidently. Double-up method is making underground and ground structure after excavation, constructing from underground bottom to first floor slab and then from first floor to ground structure simultaneously. Up-down method, one of the Top-down methods, has been studied a lot by the academic world recently. It is broadly used by construction site in urban areas but there are few studies about Double-up method. So this thesis came to the conclusion as followings by applying Double-up method in real construction site. First, Double-up method could reduce construction term over 40%. Second, Core preceding method is effective for Double-up method to reduce construction term. Double-up method costs 8 percent more than conventional method, but the entire construction cost has no big difference in case of considering overheads. If the research and development for the technology to apply Double-up method is completed, Double-up method will be used effectively on the construction site. |
