The contractors which execute the design-build project have difficulties in design management and contract administration in the pre-construction phase because they have managed construction projects focused on only construction phase so far. Moreover, they have to manage the design development stage without any contingency following-up various design revisions from the design reviews of outside experts. Therefore, the design management in the design development stage is a critical success facto. of the design-build project. The objective of this study is to structure the problems in the management skill for design development phase in the domestic design-build projects and to suggest a design development management method to settle the problems. To achieve these objectives, this study 1) analyzes the prior studies about the design-build procurement methods, 2) designs and performs a case study to embody the problems of the domestic design-build projects, and 3) proposes a method of design development management by analyzing the results of case study and interviewing experts.

we classified major changes into changes based on design deficiency, changes based on the different conditions between job site and contract documents, and changes based on the Owner's need. Then we compare and analyzed applicable regulations for supervision and work performance status at the site, and elicit problems of supervision performance based on mutual contradiction in regulations, bringing up a similar example. Based on the above, we brought up a way of improvement for the elicited problem, comparing and analyzing the laws/contract provisions/instructions related with the changes and the work performance at the jobsite, and verified through interviews with professionals of various fields for the improvement. Finally this study could elicit a way of improvement in the supervision work in conjunction with changes in civil works.

건설공사 분리발주가 공공의 이익이 매우 큰 것으로 분석됐다. 또 분리발주로 인한 공사지연, 하자분쟁 등 효율성 저하는 철저한 공사관리와 발주자 보호장치 활용으로 해결, 일부의 우려는 기우에 불과하다는 분석자료가 나왔다. 대한건설정책연구원(원장 노재화)은 박근혜 정부의 주요 국정과제 중의 하나인 공공공사 분리발주 법제화의 효과를 분석하고 향후 도입방향을 제안한 '공공공사 분리발주 법제화의 효과와 도입방향' 보고서를 발간했다. 홍성호 연구위원이 발표한 이 보고서에 따르면 공공공사의 20% 수준으로 분리발주 적용범위 결정 시 4,693억원의 공공예산 절감과 4,198억원의 부가가치, 2만6,048명의 고용이 증진되는 등 공공의 이익이 매우 큰 것으로 밝혀졌다. 또한 발주자 선택권과 자유계약 원칙을 중요시하는 미국, 일본, 독일 등 선진국도 분리발주의 법제화 또는 적극적인 활용을 통해 공공예산 절감, 부가가치 및 고용창출효과를 거두고 있을 뿐만 아니라 통합발주의 문제점도 해결하고 있다고 밝혔다. 선진국은 또 전기 소방 통신 설비공종 뿐만 아니라 건축 및 토목공종에 해당되는 여러 개의 공종을 분리발주하는 다공종 분리발주 방식을 많이 활용하고 있는 것으로 나타났다. 연구원은 또 일부에서 우려하는 다수의 공종 패키지로 인한 효율성 저하는 통합발주에서도 동일하게 발생하는 현상이며 철저한 공사관리와 발주자 보호장치 활용으로 해결 가능하므로 이같은 우려는 현실성 없는 기우에 불과하다고 밝혔다. 이와 함께 분리발주로 인해 발주자 관리업무는 일부 증가하지만 건축 및 토목공종의 일부만 분리된다면 그 증가폭은 크지 않아 크게 문제되지 않고 있으며 향후 CM용역을 통해 충분히 해소 가능할 뿐만 아니라 오히려 건설산업 발전에 필요한 'Smat 발주자 육성'이 가능하다고 전망했다. 본지는 지면관계 상 연구논문 중 공공공사 분리발주 도입에 따른 효과와 공공공사 분리발주의 도입 방향 부문만 게재한다.

On July $18^{th}$, 2003, Incheon International Airport Corporation(lIAC) signed the Construction Management Service Contract with KIDS consortium (composed of Kun-Won Eng., ITM Corp, Do-Hwa Eng, Space Croup) for the $2^{nd}$ phase construction protect consists of landfill, $\#3$ runway, remote Concourse, IAT, BHS, cargo terminal, etc scheduled to be finished by the end of 2008. KIDS dispatched qualified engineers to the Construction Management Division of IIAC for providing technical assistance to IIAC members to pursue project goals in tulle. within budget with appropriate quality level to build one of leading hul] airports for the Northeast Asia legion in the $21^{st}$ century. The work scope covers upgrading various project procedures and related computer programs, cost and schedule control, design supervision for building design including support systerns such as HVAC, fire protection, elevators and escalators, boarding bridges, electrical and communication systems, and technical support for IAT/BHS, QA/QC, field test and inspection, start-up and commissioning, etc. The purpose of this paper is to introduce the major activities of the Construction Management Services performing at the IIA project for your reference.

In public project market, design-build projects have been increased because of market trend change which enables technical competition. In this condition, its importance is also getting important. Generally, life cycle of design-build project consists of planning, preliminary design, procurement, contract, detail design, start of construction, construction, end of construction, and evaluation. From contractor's viewpoint, it has problems such as difficulties in project management and information sharing because of frequent change of charged division. To solve these problems, it is desirable to change from function-based management system to process-based management system. The purpose of this study is to develop management process model for design-build project by progress phases. This study analyzed main conflicts and decision making factors of each stage in design-build projects, then systemized management subjects' responsibilities and management points' change. And also this study defined the key information that is the key point by project characteristics and progress phases. Based on this analysis, this study did business process modeling from planning stage to construction design check stage. At last, we proposed the way to manage business process by design-build project progress.

The domestic CM business market has continued to grow, but its size is relatively small yet in comparison with the total size of the domestic construction industry. Evaluation of CM projects was conducted through questionnaire surveys. Both clients and CM firms showed positive satisfaction levels. Nevertheless, the clients' satisfaction levels were relatively low in safety management, cost management, and document and information management. Superior areas of CM tasks were time management and recovery scheduling, quality control and technical instruction, and design value engineering. On the other hand, inferior areas of CM tasks were claim analysis and dispute resolution, cost estimation, and life cycle costing. Both entities have agreed with the positive effects of CM involvement in terms of cost saving, time reduction, quality improvement, and safety incidents prevention to at least 0~5% extent.

Many defects are occurring in apartments, the main residential area in Korea. This is due to a lack of construction skills and a lack of management. As many apartments are provided to buyers, the dispute over defects after completion is increasing rapidly. The Housing Act was amended so that local governments could order contractors to repair defects. However, even if defects are resolved after a defect is generated, it is not a fundamental solution that can be satisfied because buyers have to endure the pain caused by the defect. So, it is necessary to protect the interests of buyers by fundamentally reducing defects in apartments. Therefore, in this study, it was suggested that the asymmetry of the information about the apartment buyers should be resolved at the time of sale of the apartment, the final drawings should be a contract document, the review period of the apartment house supervision should be secured, the appropriate supervisory fee should be secured at the time of contract change and the payment procedure should be improved.

After several collapse accidents of large structures in the early 1990s in Korea, the government enacted a law that architectural, engineering and construction firms are obliged to have insurance for projects over a certain size. Particularly, with regard to insurance in design and construction supervision works (i.e. engineering insurance), although several operation-based problems were pointed out from practitioners, still little research has been done on analyzing current regnlartory and operational state and suggesting policy alternatives. Hence, this study applies Delphi technique to solicit current operational problems and propose a series of improvements on engineering insurance based on interview surveys targeting major market participants: municipalities, engineering firms, and insurance companies. Key findings culminate in adopting guarantee limits based on credit evaluation, abrogating joint surety, covering a loss of life, increasing insurance entrance fee, extending time covered, and etc. Reaching a consensus on the proposed alternatives between the market participants will form the foundation for sound developments of construction design and engineering industry.
