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.

The renovation project of an apartment building can be classified into four processes: ordering the project stage, planning stage, examination and judgment stage, design stage and construction stage. However, in the domestic renovation business, the project performance process has yet to be madε systematic by stage. Of the stages involved in renovation, the design stage is the one that involves very complex roles and business processes of those involved in the project, including the project manager, architect，resident and engineer. In particular, in the design stage, the insufficiency in the ability to utilize the input information by project participants and improper decision making cause various problems in the subsequent construction and ultimately make it difficult to accomplish a renovation project that fully satisfies the residents. Therefore, the design of renovation is a very important stage to ensure a comprehensive understanding of the project performance process as well as the recognition of the design management technology. For this purpose, we aim to analyze the information utilization process with focus on the input information at each stage of the design process. The information utilization process of this study is analyzed through the processes of input information, technical tools and output to establish a decision-making method for each design stage. The aim was to implement the project performance process for the general design management.
