Abstract

It is important to have enough design and construction duration for infrastructure projects. However, recent water resource project in Korea shows several problems caused by their fast-tract schedule. National Audit Committee report several water resource projects have quality problems caused by insufficient project duration. Especially, water resource projects such as dam and water pipeline construction should have proper time to secure their structure quality. Normal project duration for these projects should be estimated based on previous similar projects' historical data analysis. However there is no standard model which can estimate normal project duration for water resource projects in Korea. There are several normal project duration estimation models for building project developed by public(LH) and private construction companies. However, there is no proper model for water resource projects. So, this study developed normal project duration model for dam and water pipeline projects using historical data and show application of models.

국내 사회기반시설 건설공사의 성공적인 완수와 고품질의 목적물 확보를 위해서는 적정한 설계기간과 공사기간의 반영이 반드시 필요하다. 그러나 최근 4대강사업과 관련된 감사원 지적사례와 같이 적정공기의 미확보로 인한 기반시설물 의 품질문제가 다수 발생되는 것으로 추정되고 있다. 특히, 댐 시설물의 공사기간은 합리적인 산정기준에 따라 계산되어야 하며 이는 오랜 기간 사용될 시설의 시공품질과 추후 유지관리와 관련된 품질에 직접적인 영향을 미침에도 불구하고 이에 대한 명확한 산정기준이나 연구가 부족한 실정이다. 사회기반시설물의 적정공기 산정을 위해 국가차원에서 표준화하여 운용중인 기준은 없으며, 일부 공공기관(LH공사 등)에서 건축, 단지분야 위주로 공사기간 산정기준을 수립하여 자체 활용중이나, 댐과 같은 수자원시설물에 대한 공기 산정기준은 없어 그동안의 경험에 기초해서 공기를 산정하고 있으며, 이에 대한 적정성 검토를 위한 기준이 없는 상태이다. 유일한 정부기준은 1974년 건설부에서 건설공사공기 표준화방안을 마련하면서 도로, 댐, 교량, 철도, 건축 분야에 대한 기준제시 사례가 있으나, 현재는 사용할 수 없는 유명무실한 상태이다. 이에 본 연구에서는 대표적인 수자원시설의 건설공사의 실적자료를 바탕으로 건설공사 규모와 실 공사기간 간의 상관관계를 통계적 기법으로 분석하여 회귀분석모델을 제시함으로서 수자원건설공사의 적정공기 산정을 위한 기초체계를 제시한다.
