Design-Build, one contractor is responsible for both the design and construction, has become more popular since the government framed the policy on how to activate the design-build projects in 1996. The reality is, however, there are many problems encounted on Contractor Selection Method for Public Design-Build Projects. The purpose of this paper is to improve the problems, no way to meet the goal(value) the owners expect from the design-build projects, for instance, not fully reflecting the characteristics of projects and owners intention, not systematical enough to judge if bidders could carry out the contract. This study will insist we introduce Best Value Procurement, which is being commonly used in some advanced countries recently, so that we would properly select the contractor suitable for Best Value concept which totally depends on the owners, types of work and specified conditions. Furthermore, by passing through the Two-Step Procedures following Pre-qualification in Best Value Procurement, we expect it lighten the bidders' burden for proposal and the owners' complicate bid administration.

Design-build is expanding gradually in large construction projects over 10billion won, and continue to work in health care facilities is increasing in this way. This constructional method in health care facilities, despite the many advantages, many problems caused by design changes are being raised. Raises the question of design changes on the side of construction contract, such as approval systems have been studied in the field of construction. The purpose of this study design in aspects of architectural planning on changing the grasp of the issues outlined in the ITB and bid evaluation criteria through consideration of the basic plan for improvement guidelines and evaluation criteria is presented. In conclusion, Design build, according to the presence of existing users are more likely to lead to design changes. Thus, hospital architecture, depending on how it is considered that constructional methods. And evaluation items of ITB(Invitation To Bidder) for a large part of the change in the variables evaluated in the hospital building is not suitable for the design build. Instead, the overall shape of the building and department, unit type and size, vertical and horizontal parts of the circulation system in the shape of the building that does not change in structure and etc should be considered for evaluation.

The purpose of this study is to suggest the development direction and performance analysis of design review system in design-build project. As a result of surveys, the fairness and transparency of design review system was abruptly increased. But local government has not fairness and transparency. Therefore this research has proposed the integration management and joint application of design review organization in design-build project. So, we expect that the transparency is raised in management of design review committee.

Numerous reports show that alternative project delivery systems (PDSs) such as design-build (DB), construction management at risk (CMR), and design-build-maintain (DBM) are increasingly used in many countries. This study compared characteristics of each PDS (design-bid-build (DBB), DB, CMR, or DBM) by analyzing quantitative data from 9 research articles. In order to compare characteristics between DBB and alternative PDSs, the study is based on principal 3 factors - Time, Cost, and Quality. DB shows the best performance in the time part and also the cost performance depending on facility type and project size. The performance of quality has minor difference among different PDSs. These results support the fact that using an appropriate PDS by the characteristic of a project makes high value of efficiency and productivity.

Various project delivery methods have been utilized by owners over the years to maximize project performance. The design-build delivery method is being increasingly used due to the advantages it can offer to an engineering construction industry. Numerous studies have advocated the use of design/build over the traditional design/bid/build delivery approach. This study represents comprehensive analysis of 40 projects from the construction industry and shows that design/build method may not provide all the benefits to project performance. This study found timesaving was a definitive advantage of design/build project delivery, but the positive effects of cost changes was not convincing. Based on the results of the study, the project management expertise and experience of the contractor may have a greater impact on project performance outcomes than focusing on project delivery strategy only.

현행 국내의 일괄입찰방식은 설계와 시공의 겸업금지로 공동도급 형태의 분담이행방식으로 운영되고 있어, 참여업체간의 의사소통 부족으로 인해 설계변경 클레임이 빈번하게 발생하고 있다. 또한 수행절차 과정에서도 사업참여자간 의견대립으로 인해 상호교류가 부족하여 프로젝트를 효율적으로 수행하는데 어려움이 있다. 이 연구에서는 일괄입찰방식, 파트너링과 시공성 분석의 특성을 파악하고, 예비적 고찰을 통한 상호교류의 영향도와 문제점을 분석하여, 일괄입찰방식 실시설계단계에서 프로젝트의 효과를 극대화 할 수 있는 효율적인 파트너링과 시공성 분석 연계 프로세스 모델을 제시하였다.

Design-build projects were devised to enhance the design technologies of the domestic construction industry and the efficiency of public works, contributing greatly to the development of construction technologies. However, as various stages of the process, such as formulation of basic plans and design documents, and deliberations proceed, claims, including changes in the requirements of clients, and design changes occur. These claims result in the delay in construction and an increase in construction costs. In this regard, this study attempted to identify main claims that delay construction and increase the costs of design-build projects, prevent claims in the future, and improve the efficiency of project implementation.

국내 중 소규모 건설 산업은 시공분야를 중심으로 발전하여 왔으며 소프트분야가 상대적으로 취약하다. 또한 다양한 발주 체계가 활용되지 못하는 문제점을 안고 진행되고 있다. 더욱이 현재 국내 건설 프로젝트들은 자금력과 기술력을 갖춘 대형 건설업체들이 경쟁 우위를 점하고 있어 중 소규모 건설업체들의 입지가 줄어들고 있다. 최근국내 외 건설시장의 대형화, 고도화와 함께 기술집약적인 공사가 늘어감에 따라 기술경쟁이 가능한 설계시공일괄(Design-Build)방식의 건설 산업이 늘어나고 있는 추세이며 규모가 작은 중 소건설기업의 상황에서는 더욱 건설시장에서 효과적인 경쟁력을 보유하여야 할 것으로 예상한다. 이에 본 연구는 디자인 빌드 방식의 성공요인과 중 소규모 프로젝트 사례조사를 한 후 AHP 분석을 통해 성공요인 도출 및 중요도 분석을 함으로써 중 소규모 건설업체의 디자인 빌드 방식의 성공적 수행을 위한 중점 관리요인을 제시하고자 한다. 그리하여 향후 중 소 건설업체의 발전과 생산성 향상을 위한 기반을 제공하고자 한다.

The orders of Design-Build Delivery System (DBDS) in a large and public construction project have been increasing. Single Source Responsibility (SSR) for design and construction, which contributes to quality improvement of design and construction, has been performed. The DBDS performs SSR for design and construction, but, it has not maximized effect because of the dissatisfied alternative analysis procedures which are based on constructability evaluation and the information system in the design step. In this research, Constructability Evaluation Factors (CEFs) that must be evaluated, investigated, and reflected in the basic design step for design-build projects. The CEF proposed and the business process of each conductor has been systematized. To propose constructability evaluation factors, first classify drawing information by the constructability evaluation sphere. CEFs must be proposed to evaluate factors according to interference among work items. Second, applicable CEFs must be classified by preference ranking and weight. Third, the values of constructability factors in accordance with building elements and work items, need to be calculated. Finally, the CEFs proposal will support rational decision making, design cost reduction, and quality improvement through the values for constructability of building elements and work items.

설계와 시공을 단일 업체가 일괄책임을 지는 턴키발주제도는 '96년 정부의 턴키활성화 대책 수립 후 대형국책사업을 위주로 그 적용이 확대되어 왔다. 그러나 업체간 과다 수주 경쟁과 대형업체들의 수주편중현상 등이 부각되면서 시민 단체와 중소기업을 중심으로 턴키/대안입찰제도에 대한 축소 적용 또는 최저가 제도로의 흡수통합방안 등이 제시되기에 이르렀다. 이에 따라 이에 따라 본 논문에서는 그 동안 국내에서 완료되었거나 진행 중인 51건의 턴키/대안 공사에 대해 시공자와 발주자에게 공기, 공사비, 품질, 신기술 적용정도 조사와 시공업체의 턴키/대안 입찰제도에 대한 의견 조사를 통해 턴키/대안 공사에 대한 객관적인 성과평가와 턴키/대안 입찰제도에 대한 실무자들의 인식을 파악하여 제도의 실효성을 평가해 보고 국내 턴키/대안 제도의 개선방안에 대해 제시해 보고자 한다.
