Abstract

The purpose of this study is to derive risk events that occurred during aircraft runway construction and analyze loss costs for project participants. For this purpose, design change data, contracted statement and completed statement were investigated. The results of this study are as follows: There were 12 risk events in the process of construction, 5 design errors and 7 construction errors. The increased construction costs due to such risk events were calculated as KRW 726 million. Of the KRW 726 million that was increased due to risk events, about 52.57% was spent by the ordering agency, and about 47.43% contractors. The increased construction costs due to such risk events are about 4.86% of the direct construction costs of KRW 14.9 billion. Based on the results derived from these case studies, a method for estimating reserve costs and construction costs considering risk events is presented.

본 연구의 목적은 활주로 건설공사에서 수집된 공사비 내역서, 설계변경 자료 등을 근거로 발생된 위험사건(위험항목)으로 인하여 변동된 공사금액을 산정하고 위험사건이 발생하게 된 원인에 따라 사업참여기관별로 손실비용을 분석하는 것이다. 본 연구를 수행한 결과, 위험사건은 12건이며, 증액된 총 공사금액은 726백만원으로 발주기관이 부담하여야 하는 금액은 약 52.57%, 건설사는 약 47.43%로 산정되었다. 또한, 계약금액의 직접공사비 149억원 대비 증액된 공사금액은 약 4.86%이며, 토공사로 분류된 위험사건에 따라 증액된 공사금액은 토공사의 직접공사비 대비 약 5.29% 그리고 건축공사로 분류된 위험사건에 따라 증액된 공사금액은 건축공사의 직접공사비 대비 약 4.04%에 해당하는 것으로 도출되었다.
