  • 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.

  • 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.

  • 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.

  • Design-build that a single entity performs whole construction process under singular responsibility is one of the project delivery system comes to take expectation effects of time savings, cost saving, and quality assurance. On the other hand, a current domestic method for selecting a design-build contractor is difficult to reflect the purpose of owner and the project characteristics when owner selects the design-build contractor. The purpose of this research is to suggest a model for deciding evaluation weights in design-build which can reflect the purpose of owner and the project characteristics. This research can help owner to select the best suitable design-build contractor for the project.

  • The use of inappropriate procurement methods to deliver construction projects has long been acknowledged as a major source of poor project performance and is particularly problematic for the Libyan Construction Industry. Poor procurement method selection has been recognised as a major contributory factor to frequent time and cost overruns. This paper offers a way of selecting specific procurement methods to maximize successful project performance. The methodology involves an intensive review of relevant literature, followed by a semi-structured questionnaire survey. The key findings of the study reveal that 11 out of its 12 common selection criteria exhibit a significant contribution to one or more project performance criteria (time, cost and quality). Project clients should therefore prioritise these criteria when selecting a design-bid-build method. Knowledge of the criteria that contribute positively to project performance will also enable clients to work out, prior to and during construction, the best measures and provisions for successful project outcomes.

  • Nuritkum Square Project is a IT Complex which is being constructed in Digital Media City. The project consists of several buildings and is a Design-build, so that the systematic construction management from design to construction stage is more important for a successful project. This study introduces the practical tasks of construction management during the project and analyze some of main tasks to increase understanding construction management in the design-build project. Based on experience of construction management in this project, we examine managerial problems which frequently occur in this kind of project, and suggest how to improve construction management in Korea.

  • 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 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.

  • Among project delivery methods, Design-Build method is becoming an increasingly preferable alternative to traditional contracting method. The Design-Build delivery method was first introduced in Korea, 1975. But it still has been producing many problems. The previous researches had been suggested several ways to improve the Design-Build project delivery but it seemed to have had no effect whatsoever. This research proposes the success model for Design-Build delivery method through the 4 steps. First, find the proper modeling method. Second, establish the As-Is model for analyzing the circumstances of Design-Build method. Third, to begin with analyzing the As-Is Design-Build model and previous researches, establish the problem model. Finally, find success factors and circumstances through the overseas Design-Build system, and then establish the success Design-Build model.
