This paper analyzes problems related to total cost changes in private investment projects, and then proposes an improvement measure for the control of cost changes within the framework of the project management, contract, human resource, project communication, cost, and time management. From the viewpoint of contract management, the basis of cost change ought to be cleared up with standardization of related provisions in the concession agreement, and potentiality of change ought to be excluded with prescription of the private investor's leading role from the design phase. Regarding human resource management, this paper proposes a standard work flow granting much sovereign rights to private parts by putting restriction on work scopes of the entrusted authority of government, and transferring the rights of assignment, contract, and control about the responsible supervisor to the concessionaire. With regard to project communication management the notification of changes on drawings and technical documents ought to be automated and the realtime database ought to be established with DMIS (Drawings & Documents Management Information System). From the cost management point of view, this thesis integrates the control of cost-change-approved items and disapproved items to one cost breakdown system, and then harmonizes the actual progress with EVMS in time management.

국토해양부는 지방국토관리청의 도로공사와 관련하여 발생하는 공사비 정보의 교환 및 공유를 목적으로 작업분류체계 기반의 공사비 관리 항목을 추가하여 전자설계도서 작성 납품 지침을 개정하였다. 이를 반영하고 문제점 개선 및 활성화를 위하여 5개 지방국토관리청에서 관리중인 10개 도로건설공사를 시범적용 사업으로 지정하여 발생하는 공사비 정보를 디지털 수량산출정보로 관리하고 있다. 시범사업을 진행하면서 건설공사에 발생하는 설계변경 업무를 전자화하여 관리하는 기능을 개발하고 추가 적용하였다. 이를 통해 건설사에서 생성한 설계변경 정보를 건설사와 발주처가 동일한 형태로 공사비 정보를 공유 및 관리 가능하도록 하였다.

Domestic dominant method in subcontract cost estimate for comprehensive program management is estimation by referencing similar cases or relying on the experience and expertise of the engaged. However, this method is not reliable due to lack of accuracy, making it harder for clients to plan and budget the program. Since budget itself is roughly estimated, it becomes a source of cost rise in the course of management due to design modifications. Therefore, the client and service providers shall calculate more accurate service cost by applying objective and scientific method in order to minimize cost rise and cost related dispute. Traditional cases, in estimating program management cost, took Top-Down approach based on precedents and experience. On the contrary, this study will categorize management structure into phases and activities, issue WBS for each phase to estimated schedule and cost for each code, and take Bottom-UP approach. By taking this approach named ICEP (Integrated Cost Estimate based on Project), Set project typical model will be developed for service cost estimating, calculate cost by applying project-specific factors. Also, by analyzing progress data and allocated management cost to complement them, more efficient construction management will take shape based on program management cost standards which reflect project-specific features.

Frequent design changes or unnecessary project executions due to illogical practice, lack of feasibility study and, hasty drive have raised problems of budget waste in Korean construction projects. Since the MOCT (Ministry of Construction & Transportation) published Master Plan for budget efficiency for government projects, there have been a lot of policy efforts for budget saving. However, it has been pointed out that cost management at the pre-construction phase, which greatly influences the cost still remains imperfect. The target cost for government clients is not being estimated reasonably, and cost controlling at the pre-construction phase is not yet being carried out properly for keeping the budget. Therefore, improved construction cost management at the pre-construction phase was proposed in this paper. The cost management systems of advanced countries were investigated for it, and the issues were drawn from the cost management systems of these countries. On the basis of the issues, the present conditions and problems of domestic construction cost management at the pre-construction phase were analyzed for suggestion.

혜성L&M(대표 장기원)의 L과 M은 Lighting과 Media의 약자이다. 89년 서광조명으로 출발해서 94년 혜성라이팅으로 상호를 변경하기까지 혜성은 국내 형광등용 전자식 안정기 기술개발에 매진해온 전문 조명업체였다. 이후 KS, Q마크, GD마크, 국산 신기술(NT), EM마크, 고효율 에너지기자재 등등 국내에서 주는 각종 마크와 인증을 모두 섭렵한 혜성은 2000년 미디어사업부를 신설, CD제작에 나섰고 2002년도에는 고효율조명기기, 인버터, 냉난방 공조설비개체 등을 아이템으로 ESCO사업에 뛰어들었다. 원가경쟁력에서 타사에 비해 강점을 갖고 있다는 혜성L&M의 ESCO사업부를 찾아가 보았다.

A government agency has been announced to increase 23,663 hundred million wons by cost of design change which occurred in the pre-construction and construction phase. As design change is a phenomenon to occur by means of a characteristic of the building design that standardization is difficult, even if it is said that a perfect design is done in design phase, design change is prevented, and it is going to decrease, and there is a limit. Because there are some causes in all of the construction project, it is change order of client, relative system, unfit design and field condition, etc. In this study, we are suggested logic and basic model of the decision making support process model that it should selecting the optimal alternative through complex and quantitative analyzed: that is cost, performance and constructability as respect Owner or CMr is executing project under the CM delivery system construction project which it occurred design change.

Public institutions recognize the importance of cost management from the planning stage but they do not have an organized construction cost estimation and management system. Thus, at the stage of planning a new public construction project and estimating the cost, those in charge of budgeting estimate construction cost based on existing data and experiences, compare construction cost estimated after the basic design stage and the execution design stage with budgets, and then decide whether to continue the project or change the design according to the budgets. Therefore, we would develop the cost prediction model through regression analysis that can predict construction cost in Schematic Design Phase of the Public Multi-Family housing. Accordingly, if public institutions have a construction cost prediction model and management system that can estimate the optimum construction cost, they can make and execute budgets in a more efficient way than they do at present.
