The present invention relates to a building underground construction method, and more particularly, to a system and method for providing a trench method information for building underground construction.

In addition to the increasing use of underground spaces in urban areas, construction methods are increasingly diversified and specialized to perform construction of underground structures of buildings within a safer and shorter construction period. Underground construction is a big part of building construction in terms of cost and period. In particular, during construction, it can affect not only this structure but also various underground works such as surrounding buildings and water supply and sewage pipes, so it is required to select the appropriate construction method for the construction of underground structures of the building through a careful examination of the soil conditions and the status of adjacent facilities. Information on the overall construction and maintenance of underground trenches, including the cost and duration of construction, should be available to the participants from the early stages of the construction project to the construction stage.
