공공공사비 산정의 공정성과 투명성 제고 방안 연구: 추정가격과 예정가격을 중심으로

Abstract

Although the profitability of domestic public construction work has deteriorated every year due to the public construction cost policy in terms of the reduction of SOC budget and efficiency of budget reduction, the government does not try to improve the system for calculating the construction cost. This study compares and evaluates the domestic and the US in the estimation of public construction cost and suggests institutional improvement methods to improve the fairness and transparency of public construction cost estimation by analyzing case studies of underpricing of construction cost and systematic problems of costing estimation process. First, in order to estimate the fair construction cost, it is necessary to enact the regulation of the construction cost, to specify the reasons when cutting, and to introduce the screening system of the construction cost. In terms of the flexibility of the budget operation system, it proposes a contract considering the balance of the winning bid, an adjustment of contract amount after contingency, and a value engineering after approximate contract. Second, in order to estimate the transparent construction cost, it proposes to disclose all calculation data of the construction cost, and proposes the real name system for those who estimate the construction cost. Third, in order to remedy the unfair reduction of the construction cost, it proposes the adjustment of contract amount due to the design change or other changes in the contract contents and the appeal for government dispute mediation. In order to secure its effectiveness, it proposes penalties for those who estimate the construction cost. Finally, it proposes to secure the expertise of those who estimate the construction cost and to estimate the construction cost by a qualified person such as construction cost manager, cost analyzer, and so on.
