Abstract

Recently, as the scale of a construction project has become larger and more complicated, there are many cases where construction projects with complex structures are carried out in a fast track method to save construction duration. In the fast track method, the proper division of construction phases is an important issue in determining the overall project period. This study presents a rational phase division method that can be applied when a construction project with complex structures is carried out as a fast track. For this study, a subdivided work breakdown structure (WBS) is developed using the construction of 4 soccer stadiums as application examples, and the schedule is analyzed by dividing the construction process of major phases. To this end, five proposals are applied to analyze the adequacy of the fast track phase division. For the draft with the minimum construction period, the fast track phase division and the schedule model of by each phase were presented. This methodology can have an application in the appropriate phase division and schedule model by construction phase when fast track is applied in large construction project of a similar size.

최근 공사규모의 대형화, 복잡화 등으로 토목, 건축, 기계 등의 복합공종으로 구성된 공사들은 공기절감을 위해 패스트트랙(Fast Track) 방식으로 진행되는 사례가 많으며, 패스트트랙 방식에서는 적정 단계구분이 전체 프로젝트의 공기 책정에 중요한 사안이다. 본 연구에서는 복합공종으로 구성된 건설공사가 패스트트랙으로 진행될 때 적용할 수 있는 단계구분 방식을 제시하고 있다. 이를 위해 연구에서는 토목, 건축공사로 구성된 4개의 축구전용경기장 공사를 적용 사례로 분석하여 세분화된 공정분류체계(Work Breakdown Structure, WBS)를 통해 주요 단계별 공정 구분에 의한 일정표를 분석하고, 5가지 시안을 적용하여 패스트트랙 단계구분의 적정성을 분석한다. 분석된 시안중에서 최소 공기를 갖는 시안에 대하여 패스트트랙 단계구분 및 단계별 주요 공정의 구성 모형을 제시하였다. 이러한 방법론은 패스트트랙이 적용되는 유사한 규모의 대형 복합공사에서 패스트트랙 적용 시에 적정 단계 구분과 단계별 공정 구성 체계에 활용성을 가질 수 있다.
