다국어 초록 (Multilingual Abstract)

The procedure of risk management includes risk identification, risk analysis, and risk response. Among them, risk identification in said to be the most important step.
The purpose of this paper is to identify and classify the various risk factors associated with the work of the early construction phase. This paper established the Risk Breakdown Structure(RBS) by classifying the risks into the three main groups, Common risks, risks for Earth works, and risks for Foundation works. The common risks are identified and classified by considering various aspects of the early construction phase such as financial, political, constructional aspects, etc. The risks for Earth works and Foundation Works are identified in detail by surveying technical specifications, relevant claim cases and interviewing with experts. There risks are classified based on the Works Breakdown Structure(WBS) of the construction phase. The WBS presented in this paper classifies the works of the early construction phase into four categories; excavation, sheeting works, foundation works, footing works.
