Various public construction projects have been performed for public welfare and appropriate evaluation of the effectiveness and efficiency has been required. In accordance with legislation of a post construction project evaluation in Construction Technology Promotion Act, all construction projects that exceed 30 billion won in budget are required to perform post evaluation. Korean Government provides post construction evaluation manual that includes both quantitative and qualitative criteria. However, it only provides general concepts and procedures not but detail guidelines for different construction project types and characteristics. Therefore, this paper developed a standard format for qualitative evaluation using survey through analyzing previous cases and research. As a result, the developed standard for survey can be applied for most civil and architectural facilities. However, it will need further research regarding establishment of detailed evaluation criteria for each type of facilities and data storage system for feedback.

Recently, a concept of the downtown area was progressively extended by improvement of rapid transportation system and development of the most advanced telecommunication industries. And underground has become bigger in addition deeper, Excavation methods which construct a structure were changed according to construction environments. Top Down methods which are continuous with architectural plan differ from existing excavation methods innovatively, pre-founded column is an important factor for construction methods, duration, expenses. Therefore, this study considers application by investigative methods according to comparison, analysis on loading test result of on site inspection and estimated results of bearing capacity for structure pre-founded column. As a result, almost designing eclipse appeared prior value which didn't arrive result of load test. Also, evaluate permanent load for the compressive stress acting on head of cast-in-place after basic structure was installed. Then, applying stress generally is reduced by confining effect with foundation.

정부등 공공기관에서 시행하는 건설공사 예정가격 작성시 적용되는 2006년 하반기 실적공사비 적용대상 공종 및 단가 931개(기계설비 216, 건축 335, 토목 350)가 지난 8월 14일 공표되었다. 실적공사비 단가는 재료비, 노무비, 직접공사 경비가 포함된 공종별 단가를 계약단가에서 추출하여 유사공사의 예정가격 산정에 활용하는 방식으로 공공건설공사의 예정가격 작성시 적용되고 있다. 또한 실적공사비 단가는 공공건설공사의 설계조건이 유사한 공종을 대상으로 계약단가가 설계단가 대비 ±25% 범위 내의 단가로 2006년 하반기 실적단가 설계가 대비 평균 낙찰률이 70% 수준이다. 대부분의 공공기관에서 예정가격 작성시 적용하고 있는 실적공사비 단가는 종전의 표준품셈에 의한 예정가격 작성시보다 공사예정가격이 낮게 산정되고 있다. 따라서 설비건설업계도 이를 감안하여 반드시 적정공사비를 확보할 수 있는 금액으로 입찰에 참가해야 한다.
