Abstract

Recently, the number of project delay-related claims and disputes in Korean construction projects has been increasing rapidly. This suggests that the domestic construction contract practice, which has traditionally been superior to the client, is changing into a mutually balanced relationship among the contracting parties. The project delay analysis selects the application method according to the type of schedule approved at the start of the construction and how the schedule management was performed during the construction. The most important prerequisite for project delay analysis is that a complete CPM schedule agreed at the beginning of the construction is prepared and the actual progress of such schedule is well documented. This study is about applying the project delay analysis methodology of a case where a contractor claims damages to a client while constructing a large new private building construction project. In this study, it is determined whether the application of the as-planned analysis method is appropriate to the incomplete CPM schedule and then proposes the as-planned vs. as-built analysis method based on the new standard as an alternative. Next, apply the as-planned vs. as-built analysis method to the schedule in the case project, and then compare it with the result of the as-planned analysis method. The purpose of this study is to suggest a project delay analysis method suitable for the domestic schedule management practices, so that it can be used as a meaningful reference in project delay disputes and litigations of domestic construction projects.

최근 국내 건설공사에서 공기관련 클레임과 분쟁의 발생건수가 급격한 증가세를 보이고 있다. 이러한 현상은 전통적으로 발주자 우위의 국내 건설 계약관행이 계약당사자간 상호적이며 균형적인 관계로 변화되고 있음을 시사하는 것이다. 공기지연 분석은 건설공사 착공시 승인된 공정표의 종류, 공사진행 과정에서 공정표 실적관리를 어떻게 했는지에 따라 적용 방법을 선정하게 된다. 그리고 공기지연 분석에서 가장 중요한 전제조건은 공사초기에 합의된 완전한 CPM공정표가 준비되어 있고, 그러한 공정표의 실적관리가 제대로 기록되어 있는 것이다. 본 연구는 국내 민간 발주자의 대형신축건물을 공사하는 과정에서 시공자가 손해를 보았다며 발주자를 상대로 손해배상을 청구한 사건의 공기지연 분석 방법론을 적용에 관한 것이다. 본 연구에서는 불완전한 CPM공정표에 계획공정 분석법 적용이 적절한 지 판단하고, 이에 대한 대안으로 새로운 기준의 계획공정 대비 완료공정법을 제안한다. 그리고 사례 프로젝트에 계획공정 대비 완료공정법을 적용한 다음, 계획공정 분석법 결과와 비교분석한다. 본 연구의 목적은 국내 건설공사의 공정관리 현실에 적합한 공기지연 분석방법을 제시함으로써, 향후 국내 건설공사의 공기지연관련 분쟁과 소송에서 의미 있는 참고자료로 활용될 수 있도록 하는 것이다.
