In this study, propose a building Online system based on information sharing that minimizes the unnecessary expenses used to for the management of slope face-map newly created through new road, extension and linear improvement. Also, as a result of the economic feasibility analysis by quantitatively estimating the initial invest costs and the benefits resulting from the cost reduction, the B/C ratio is evaluated to be 1.0 or more after 2 years, be used to effective management plan.
