Construction cost index is generally used to estimate the new project cost based on past construction data and to adjust the contract cost when the price change of various articles and items of expenditure composing the contract occurs. In Korea, it is mostly used for modulation of construction contract cost due to fluctuation of prices. However the method for making cost index had some problems in calculating cost index of each expenditure item that could not properly reflect the change of construction cost. To supplement these problems, the research of developing construction cost index has been executed. Through the precedent research, these problems were partially resolved but still remain. Therefore this research proposes the method for making cost index that utilizes representative items of labor, material, equipment by analyzing bill of quantity of road construction, through analysis and comparison of precedent studies. By using this method, it is expected to solve the problems which were not reflected in preceeding studies.

In 1997, after Construction Management was introduced, it has been ten years; moreover, there has been many thesis until recently. However, in the past thesis, studies of Construction Management were limited to the public and standards for an activation were not certain. So, in this study, using Public Announcement of CM Ability Valuation, we analyzed the market of the domestic CM in the aspect of the number of contracts and the sum of money. The number of domestic construction contracts has decreased since 2002. In contrast with the number, the sum of money has increased. And the market of CM has been extended. However, the occupancy rate of the contract money was low in contrast with the number of contracts. But comparing with the growth rate of economy and Construction market, that of the CM market has been extending. Through this study, we decided that the market of CM was being activated.

There are several causes to recalculate the contract amount in public construction projects. Among them, the escalation clause was introduced in 1969 and now the condition to recalculate the cost is effective after 90 days from the date of contract and the rate of fluctuation should be more than 3% from the date of bidding. The two calculation methods for the rate of fluctuation are item-adjustment and index-adjustment. According to the results of investigation into 4 public institutions and 163 projects, all of them have used the method of index-adjustment and the rate of projects that spend over 6 months obtaining the approval of contract amount adjustment is more than 90%. The reason for spending lots of time is caused by problems of the calculation method on the price fluctuation rate. Therefore, it is necessary that the calculation method should be diversified to cope with the problems and a option of the builder should be expanded as well. Furthermore, if the way to apply correction factors to construction price index and average index based on the producer and consumer price index made by the bank of Korea is added, then the duration will be reduced without additional expenses. This study proposed the diversification of the calculation method using price fluctuation rate and builders' expanded options as improvement on the managerial method of Price Fluctuation System for the prompt and efficient contract amount adjustment.

민간건설공사 대금 지급보증제 도입과 불공정 특약 규정 무효 등을 주요 내용으로 하는 개정된 건설산업기본법이 지난 8월 6일 개정되어 내년 2월 7일부터 시행된다. 개정된 법률에서 계약금액 및 기간 변경 불인정, 계약체결 전 예측이 어렵거나 구체적으로 정하지 않는 내용의 책임 전가 등 건설공사 도급계약 내용 중 계약당사자 간 현저하게 불공정하고 불평등한 특약은 효력을 잃는다. 또한 민간건설공사에서 수급인은 계약이행보증에 대응하여 발주자에게 공사대금지급보증 또는 담보제공 요구를 할 수 있게 되며, 계약당사자가 대등한 입장에서 공정하게 계약을 체결하도록 표준계약서 사용이 권장된다.

대한설비건설협회는 해외건설 현장의 불공정 하도급거래 관행을 개선코자 제18대 대통령직 인수위원회 및 국토교통부, 공정거래위원회 등 관련 부처에 해외건설업 표준하도급계약서 제정을 건의해 왔다. 특히 Back to Back 원칙(발주자와 원도급자간 계약내용을 하도급계약에 적용)에 따른 하도급 대가 유보행위와 계약금액조정 불인정 등 각종 불공정한 하도급계약 조건으로 인한 회원사의 피해를 방지할 수 있는 해외건설업 표준하도급계약서 제정을 추진했다. 그 결과 국토교통부와 공정거래위원회가 공동으로 우리협회 의견이 반영된 '해외건설업 표준하도급계약서'를 제정하고 지난 7월 3일부터 시행에 들어갔다.

The construction of a facility is an act whereby infrastructure such as roads and railways and other facilities such as housing and office spaces are constructed, and due to the characteristics of the relevant industry where such construction is carried out in a custom order method, it requires a long period of time mostly. While the construction is carried out over a long period of time, fluctuations in the price of raw materials required for the construction occur. Therefore, the cost of the construction also fluctuates inevitably. The fluctuation of the construction cost meshes closely with the profit of a constructor and the efficiency of government spending. Therefore, it is necessary to maintain the construction cost at a reasonable level by adjusting the construction cost rationally in order to secure the required construction quality and spend the budget efficiently. The buffer system for solving such problem is the contract amount adjustment system by fluctuations in prices (Escalation/De-Escalation). In this study, the method combining the escalation method based on the item adjustment method was suggested for an efficient contract amount adjustment method. In addition, it is proposed that there be an investigation and codification of matters not applied to government acts and regulations on contracts related to the adjustment of fluctuations in prices legally.
