Abstract

Various studies has tried to unveil causes of cost overrun and schedule delay in the road construction project. However, these causes need standardization due to difference by guidelines, relevant research, and facilities. Therefore, this study identifies and elaborate standard road construction cost and schedule variation factors that can be used in the planning and execution of the project. variation factors have been derived and grouped through literature review and modified and supplemented through expert interview. In addition, the connection with the relevant guidance factors is confirmed and the usability is reviewed by applying actual road construction cases. The factors suggested in this study comprehensively include factors of related guidelines and previous research, more clearly distinguish, support decision making.

건설공사의 공사비 초과 및 공기 지연에 대한 원인 파악을 위해 공사비·공사기간 변동 요인을 조사하고, 이를 분석·관리하기 위한 노력이 이루어지고 있다. 하지만 이러한 변동 요인들은 관련 지침, 관련 연구, 시설물별로 매우 다양하여 표준화된 정보 수집 분석·관리체계의 필요성이 대두된다. 따라서 본 연구는 사업의 계획 및 진행단계에서 활용 가능한 표준 도로건설공사 공사비·공사기간 증감요인 분류체계를 제시하고자 한다. 본 연구는 국내·외 문헌 고찰을 통해 공사비·공사기간 증감요인을 도출 및 그룹핑한 후 전문가 자문을 통해 수정, 보완하였다. 또한 관련 지침 요인들과 연계성을 확인하고 실제 도로건설공사 사례를 적용하여 활용성을 검토하였다. 본 연구에서 제시한 표준 도로건설공사 공사비·공사기간 증감요인 분류체계는 관련 지침 및 연구들을 포괄적으로 포함하고, 증감요인을 더 명확히 구분하는 것을 확인하였으며, 실무적인 의사결정을 지원할 것으로 기대된다.
