In recent years, as construction work has become increasingly larger and more complex, the portion of the construction cost, amount and duration earthworks account for in the total construction work is on the increase. Therefore the selection of the construction method in earth works is getting more and more important. In this study, the experimental research was conducted on the two construction sites to practicalize the construction method on the construction site of sinking the underground structures in the underground direction after manufacturing them on the ground. As a result, it was analyzed that the proposed construction method of conducting the work by installing the guide wall instead of retaining wall. could reduce the time and cost required to install and dismantle the temporary facilities and the total construction duration was shortened and 10 percent of the construction cost was reduced. In addition, it was analyzed that the utility value of the land can be increased and the underground space can be used to the maximum, since it is possible to construct the underground structure up to the site boundary line without installing the earthen barrier.
