With the trends of massiveness and complexity of construction, the main agents of construction have considered the various types of risk management strategies to minimize the loss caused by the risk factors from the nature of construction project, regional characteristics, and scale of construction. The risk management has been conducted, because the risk factors have exacerbated the condition of construction in terms of the level of productivity, quality of construction, atmosphere, and budget. Based on thε interests regarding risk factor management, the current study suggests the work breakdown structure-based process. Additionally, based on the work breakdown structure, the risk factors on constructions are identified and stratified depending on the level of salience of each risk factor. The purpose of result is to lead Korean Land Corporation understand and control the risk factors properly for the advanced construction process of Korean Land Corporation. Ultimately the current study contribute to advance of efficient risk management strategies by using ANP method, which identify and control the primary risk factos depending on the impact of the interaction and subordinate relationship between risk factors.
