Abstract

Measuring and evaluating project progress and performance are the key element of the construction project success. Construction progress is typically measured quantitatively by evaluating cost and time allocated to the project deliverable, and thus properly integrating cost and time is essential to the project management. This research was performed to propose an alternative methodology to integrate the cost and time and provide a framework for the progress measurement. The researchers developed a typical work process for the cost and schedule planning and also developed an alternative cost-schedule integration method by using progress integration units (PIU). A discipline of a construction phase served as a common level for WBS and CBS integration, so the PIUs'were defined under discipline. A case study project was selected to validate the developed methodology. The result showed the proposed method improved efficiency of cost and time integration. The result also showed the excluding material for the progress measurement purpose significantly reduced the bias of progress measurement.

건설 프로젝트의 생산과정에서 성과를 지속적으로 측정하고 평가하는 것은 프로젝트관리의 성공적인 수행을 위한 핵심요소이다. 성과는 일반적으로 목적물에 할당 된 공정과 원가 관련 정보를 정량적으로 평가함으로써 측정되며, 객관적인 성과측정을 위해 공정과 원가가 통합적으로 계획 관리되어야 한다. 본 연구는 공정과 원가의 통합 모델을 통해 성과 측정 방법론을 제안하고 진도관리의 기반을 마련하는데 목적이 있다. 이를 위해 공정계획과 원가계획의 표준화된 업무 프로세스를 개발하였고, EVM과 기존의 통합 모델을 분석하여, 성과측정 유닛을 활용한 WBS와 CBS의 통합 방법론을 제시하였다. 플랜트 프로젝트의 시공단계를 중심으로 공통 성과측정의 대상은 공종으로 선정하여 성과측정 유닛을 규정하고 공정과 비용정보를 연계시켜 성과비율을 산정하였다. 또한 리소스의 적용시 원가요소 중 소모성자원의 비용을 배제하여 진도측정의 객관성을 향상하였다. 본 결과는 실제 플랜트 사례 프로젝트에 적용하여 실증되었으며, 개발된 방법론은 향후 프로젝트의 성과를 보다 객관적인 기준으로 평가할 수 있어 보다 효과적인 진도관리 방법이 될 것으로 판단된다.
