The purpose of this study is presume that reasonable construction period of constract and appropriate number of persons for works according to reconstruction. This study is presume reasonable construction period of constract and appropriate number of person of reconsruction with a case study out of apartment R.C construction. The result of this study are as follows: 1. In case of four building of apartment Resonable constrution period: 750days$\sim$800days, the average(1day) number of persons under working: 63.5 persons. 2. In case of four building of apartment Resonable constrution period: 850days$\sim$900days, the average(1day) number of persons under working: 100.6 persons. 3. In case of four building of apartment Resonable constrution period: 1000days$\sim$1050days, the average(1day) number of persons under working: 145.0 persons.

Index adjusted ratio method has been widely utilized in public construction sector for contract sum adjustment by price fluctuation. In this method, the Production Price Index are used for the base ratio, but the PPI can't reflect the character of construction project in respect of the selected items and weight. In this research we prove the problem of using the index adjusted ration method in contact sum adjustment by price fluctuation, and improve it by using the construction cost index, which has the property of construction project. And we figure out the efficiency of the proposed method by case study.

The purposes of study is to propose a new method contract price adjustment in construction projects. The research method of this study includes a case analysis and questionnaire survey. The results of this study are as follows: 1) For improvement method of contract amount adjustment, enactment for legislation pertaining to computation methods such as military's organization through total unit cost, and price flexibility computation at the point of design modification were presented. 2) Arithmetic formulas for cases in which volume is deleted or modified below the price flexibility exemption amount or in which there is no change to quantity, at the occurrence of design modification resulting from price flexibility, were proposed.

공정거래위원회(위원장 정호열)는 지난 11월 6일 표준하도급계약서를 개정하고 이날부터 시행에 들어갔다. 개정된 표준하도급계약서는 발주자의 요청에 따라 설계변경이 이루어진 경우 증가된 물량 또는 신규비목의 단가는 설계변경 당시를 기준으로 산정한 단가와 이 단가에 낙찰률을 곱한 금액을 합한 금액의 100분의 50 이내에서 당사자간 협의해 정하도록 했다. 다만, 발주자의 요청 이외의 사유로 설계변경이 이뤄진 경우에는 종전과 같이 $\Delta$증감된 공사의 단가는 수급사업자가 작성한 산출내역서 상 단가를 적용하고 $\Delta$신규비목의 단가는 설계변경 당시 기준으로 작성한 단가에 낙찰률을 곱한 금액을 적용토록 했다.

Article 64 of the Enforcement Decree of the National Contract Act The requirement of the pre-amendment statute related to the adjustment of the contract price was 5% or more of the price fluctuation rate from the date of the contract. However, the meeting requirement was changed from 5% or more to 3% or more from the date of signing of the Presidential Decree No. 19035 to 2005. 9. 8. The method of adjusting the contract amount was also changed to determine the contractor's desired adjustment method at the time of contract. Alleviating these requirements and revising the empowerment of contract partners is intended to prevent difficulties in achieving smooth objectives by applying to public construction contractors without unfairly benefiting or unfavorable to contract partners. Even if the standards are relaxed and the rights are secured as described above, if the existing provisions for the adjustment of price fluctuation are applied, unlike the original purpose of the government system, the Korea Bank's price economic statistics classification method and the contract construction classification criteria applied in public construction work Due to the inconsistency, it can be seen that the amount of adjustment for price fluctuation by construction type is excessive and underestimated. Therefore, the purpose of this study is to analyze problems through cases and to make appropriate construction cost adjustment through improvement measures.

전통적으로 주요 EPC(설계, 구매, 시공) 공사는 최초의 엔지니어링 작업(FEED : Front End Engineering Design)을 한 후, 경쟁입찰을 하여 총액계약(Lamp Sum)으로 공사를 수행했다. 최근에 EPC시공자의 위험부담을 줄이는 한편, 발주자는 경쟁적인 시공자를 확보할 수 있는 기회를 확대하면서 협상기간을 단축하교 조기착공을 위해, Lump Sum 가격을 늦게 결정하는 방법을 고려한다. CLST(Converted Lump Sum Turnkey)계약방식은 최초의 엔지니어링 작업을 한 후 경쟁입찰을 통해 1차 계약을 맺고(설계 및 특별 자재 공급에 대한) 공사를 수행하다 설계가 충분히 진행되고 핵심자재에 대한 견적이 입수되어 발주 가능한 시점 및 하도급사를 선정할 준비가 된 시점에서 1차 계약을 변경해 2차 계약을 맺는다. 2차 계약 시 1차 시 맺은 계약조건(직접공사비, 일반관리비 및 이윤, 최대한도 금액이 포함됨)을 기준으로 하되, 발주자가 Open Book 형식으로 공사비를 평가하고 재협상하여 Lump Sum 금액으로 전환해 합의한다. 이후 Lump Sum Tumkey 계약과 동일한 형식으로 공사를 수행한다.
