Abstract

The New Excellent Technology (NET) designation system, introduced in 1989 for the purpose of promoting the development of domestic construction technology and enhancing national competitiveness, reviews the statement of construction cost of new technologies. And the cost reduction effect such as design, construction, and maintenance cost and the effect of reducing the construction duration are evaluated as an evaluation criteria of economic feasibility. However, in this evaluation process, differences of opinion between the institution of construction cost estimating standard management and the new technology developer about unique technologies frequently occur. In addition it is difficult to objectively compare the construction duration with existing similar technologies because there is no information on productivity as the current cost estimating standards for new technologies only present the required amount per unit quantity. In this study, the current state of cost estimating criteria review procedure, evaluation criteria, and cost estimating standards establishment method were analyzed when screening for the designation of a new construction technologies, and compared with overseas cost estimating standards, measures to improve the cost estimating standards of current construction new technologies were suggested. Through the improved cost estimating standards of this study, it is expected that cost information on new technologies will be provided to clients in more detail than the current ones, and the availability and applicability of new construction technologies would be improved by simplifying the construction cost calculation process more.

국내 건설기술의 발전을 도모하고 국가경쟁력을 제고하기 위한 목적으로 1989년 도입된 건설 신기술 지정제도는 심사과정에서 신기술의 원가계산서를 검토하고, 설계·시공 공사비, 유지관리비 등 비용절감효과와 공사기간 단축 효과를 경제성 항목으로 평가하고 있다. 그러나 이 과정에서 고유기술에 대하여 공사비산정기준관리기관과 신기술 개발자간의 의견차이가 빈번히 발생하고 있으며, 또한 현행 신기술에 대한 원가산정기준이 단위수량당 소요량만을 제시하는 방식으로 생산성에 대한 정보가 부재하여 기존 유사 기술과의 공사기간에 대한 객관적인 비교가 어려운 실정이다. 본 연구에서는 건설 신기술 심사 시 원가산정기준 검토절차와 심사기준, 신기술 품셈 작성방법 등 현황을 분석하고 해외 원가산정기준과 비교하여 현행 건설 신기술의 원가산정기준 개선방안을 제시하였다. 제시한 개선방안은 작업조 기반의 생산성 정보를 제공하고, 적용단가를 제시하여 원가기준의 투명성을 확보할 수 있도록 구성하였으며, 신기술의 특성을 고려하여 재료비와 기계경비에 대한 원가정보 역시 제공할 수 있도록 하였다. 본 연구의 개선된 원가산정 기준을 통해 발주자에게 신기술에 대한 원가정보를 현행보다 세부적으로 제공하고, 공사비 산정 과정을 보다 간소화함으로써 건설 신기술의 활용과 현장적용성을 향상시킬 수 있으리라 기대된다.
