Abstract

In the delivery systems for public construction works, design-build methods such as turn-key and alternative have contributed to improving the quality of structures and developing the construction technology. However, it is pointed out that construction based on a design-build method is likely to waste a budget due to its higher contract price than construction based on a design-bid-build method. Other issues such as contract monopoly, bid rigging and deliberation irregularity in design-build. Since there are not much works have been accomplished to comparatively analyze the actual performance and effect based on delivery methods, discussing and judging the performance and effect of each deliver method with limited information could lead to an error. Thus, this study by extensively investigates the actual project cost data, ranging from contract price to the construction cost of the public construction works and comparatively analyzed the characteristics of each delivery method about cost structure and fluctuation trend. This work is expected to assist stake-holders in properly understanding delivery systems for public construction works and promoting their efficient management.

공공건설공사 발주제도 운영에 있어 기술경쟁을 지향하는 턴키 및 대안방식 등 설계 시공일괄방식의 경우, 시설물의 품질향상 및 건설기술 발전에 기여하였음에도 불구, 계약되는 공사비가 설계 시공 분리발주방식을 적용하는 공사보다 높아 예산낭비 우려가 있다는 지적과 함께 수주독점, 입찰담합, 심의비리 등의 문제가 쟁점이 되고 있다. 그러나 실제 발주방식별 사업성과와 효과에 대해 정밀 비교분석한 사례가 없는 실정이며, 단순히 낙찰률 등 사업의 한정된 일반적 정보만으로 사업효과를 논의하고 판단하는 것은 자칫 오류를 범할 우려가 있다. 이에 공공 건설공사를 대상으로 계약에서 준공에 이르기까지 실제 집행한 공사비 자료를 광범위하게 조사하여 비용의 투입구조 및 변동추세 등 발주방식별 특성을 비교분석하고 공공건설공사 발주제도의 올바른 이해와 효율적 운영을 도모하고자 한다.
