Abstract

The government and local governments are utilizing regulations, policies, and various project management techniques at each project stage to effectively and systematically manage public construction projects. However, the increase in construction costs continues to occur. In order to solve these problems, this study attempted to collect cases of existing public construction projects and analyze historical data. And it would like to derive the impact factor of increased construction costs. Based on the results, a plan was proposed to prevent the causes of increase and minimize in construction costs. The main reasons for the increase in costs were the occurrence of civil petition, differences between design documents and site conditions, and changes due to requests from the owner and changes in the business plan. And to solve these problems, this study proposed improvement for each cause from an institutional perspective, along with interview with experts and project owners. The results of this study are significant in improving the process of existing public construction process and presenting key inspection and review items for each major inspection stage in order to solve problem resulting from the analysis of the performance of public construction projects.

공공건설사업을 효과적이고 체계적으로 관리하기 위해서 정부와 지방자치단체는 건설사업 관련 제도와 정책, 그리고 사업단계별로 다양한 사업 관리 기법들을 활용하고 있으나 공사비의 증가는 계속 발생하고 있다. 이러한 문제를 해결하기 위하여 본 연구에서는 기존에 수행되었던 공공건설사업의 사례를 수집하여 실적 데이터를 분석하고 공사비의 증가 원인을 사례에 기반하여 도출하고자 하였다. 그리고 분석 결과를 토대로 공사비의 증가 원인을 예방하고 공사비 증가를 최소화하는 방안을 제안하고자 하였다. 분석 결과, 공사비 증가 원인은 민원 발생, 설계도서와 현장상태의 상이, 그리고 사업계획 변경 및 발주자의 요청이 주요 원인으로 도출되었고, 본 연구는 전문가와 발주자의 자문과 각각의 원인별 개선 방안을 제도적인 측면에서 제안하였다. 이 연구의 결과는 공공건설사업의 공사비 증가 문제점을 해결하기 위하여 기존 공공건설 프로세스를 개선하고, 주요 점검 단계별로 중점 점검 및 검토 사항을 제시하였다는 것에 의의가 있다.
