Recently, a delivery system has been rapidly changed in the global construction market. Also, construction projects are becoming bigger and more technology-intensive. A lot of projects have been delivered by Design-Build(DB) System; from the standpoint of cost, approximately 40% of delivered constructions by a Public Procurement Service were DB in 2009. Nevertheless, the achievement has not surpassed our expectations on management of the project cost. On the characteristic of DB, the reasons why that happens are that projects contract have been signed after the Design Development Stage; the insufficient review about new technology and up-to-date construction methods; a lack of discussion in process of design. Those reasons cause a risk of increasing Cost of the projects. In order to solve these problems, it is desirable to find Cost-increasing factors in promoting the projects and select on the order of priority for Risk-Factor with careful management. Therefore, this study analyzed the weight of each phase of the project on the authority of properties of DB project, and identified Risk-factors which is increasing the cost on the aspect of project management. Based on this analysis, the impact assessment of Risk-factor is evaluated through the Failure Mode and Effect Analysis(FMEA).

In order to build up competitive power in construction market and to cope with international policy, Design-Build bidding is one of the viable bidding system, encouraging collaboration between design office and building construction firm. Design-Build is a promising delivery system to help expediting schedules, saving costs, and improving Quality. However, the problems of Design-Build project in the domestic construction industry are not to be able to take advantages of fast-tracking and value engineering process, because of the problems of inappropriate system and participants' inexperience. The purpose of this study is to suggest alternatives for Design-Build bidding of public sector in the domestic construction industry in the costs, quality and time aspect.

Ministry of Construction & Transportation prescribes that all of the construction works including Design-Build whose cost more than then billion won must be applied VE at the design phase. It is difficult to apply VE at the design development phase to design-build projects under current design-build contract because design should be proceeded with fixed price by bidding. Therefore the present study suggests an application of incentive which can maximize the effectiveness of design VE in design-build projects after analysing current design-build's characteristics and difficulties of design VE application.

사업에 미치는 환경적 요인들이 점점 다양해짐에 따라 사업평가에 있어서 사업 자체의 성과뿐만 아니라 기업의 환경과 특색까지도 고려할 수 있는 에이전트의 필요성이 부각되고 있다. 본 연구에서는 사업의 타당성 검토와 진행패턴 분석 시 기업의 특수성이 반영된 평가요인과 사업형태의 분류에 따라 에이전트가 각기 다른 방식으로 동작하도록 설계하였다. 본 에이전트는 사업유사성 분석방법으로 판별 분석과 획득가치 접근법을 사용함으로써 유사한 기존사업의 진행패턴과 성과패턴 및 정보를 경영자나 사업담당자에게 보다 직관적으로 제공할 수 있다. 이러한 방법은 경영자로 하여금 기존 시스템 하의 일관된 방식에 의한 평가의 오류를 줄이는 데 도움이 될 것으로 기대된다.

Current design-build contract is the type of joint venture, but performs by separate party which causes change orders due to the lack of communication between design and construction, so it cannot lead the main object which is the integration of design and construction. Furthermore, the current design-build contract is impossible to reduce the project costs by VE at the design development phase because the design proceeds with the fixed price through bidding. Like these limitless, the analysis results of the case of VE in the design-build projects, several problems that are prevented from active design VE are elicited by the project participants. Meanwhile, Ministry of Construction & Transportation decided to enlarge the VE review system lately. Therefore, in this study, it presented model of design VE partnering of design-build and partnering agreements form to apply design VE and to try to be able to lead the design VE to be more successful in public design-build projects.

In the current domestic design-build contract, design and construction are separated due to prohibition of outside work. but instead the design-build contract adopts a method of fulfilling each assignment as a joint venture, which makes it difficult for participants to communicate each other and often require changes of design. also, It is difficult to performance efficiency project that they don't want to share useful information related to design and construction. In this study suggests how to maxmize the effiency of the project by proposing a process model connected with an efficient partnering and constructability in a deign development phase of design-build constract.

Recently, the design-build delivery system is being generalized in domestic construction project. The design-build system is becoming an increasingly preferable alterative to design-bid-build delivering method. In design-build project, however, a large construction company and design firm make up consortium as a design-build contractor rather than single company performs design and construction work. In this case, usually the construction companies take a leading role but due to their lack of managerial know-how in the design-build system, they could miss the merits of this approach. Therefore, it is necessary to investigated throughly the function and information flows all over the design-build project. In this research suggests a process model and database in the whole phase of design-build project. This process model and database system will also support to Improve the consistency of functional process and minimize incoherent activities in each phase of design-build project.

The selection of the reasonable project delivery system (PDS) is crucial for a successful performance of a project, which means to achieve project objectives. Furthermore, the project performance has been tightly related to the selection of PDS appropriate to pertinent project characteristics. In this context, the ministry of finance and economy of Korea launched two new project delivery systems called "Best Value Contract (Design-Bid-Build)" and "Bridging Contract (Design-Build)" in October of 2007 by revising enforcement ordinances of "Act on Contracts to Which the State is a Party". For efficient operation of the new project delivery systems, this paper suggested a PDS selection model which supports decision making of the reasonable PDS for a pertinent project by assessing characteristics of the public construction projects, both quantitatively and qualitatively. In addition, a PDS performance evaluation model was proposed in order to get feedback on the result of the PDS selection and the operation for the succeeding project. The standard models suggested in this paper might be used as a tool to support the decision making of the public organizations.
