The report of the Korean Board of Audit and Inspection(BAI) on May 2007 indicates the problems of Life Cycle Cost (LCC) analysis and evaluation in the Design-Build(Turn-Key) and alternative bidding system. The point which the report indicates is that the cost estimation system for LCC analysis has nothing in common each other and there's no consistency among the repair cycle and ratio per facilities parts. For solving these problems, BAI demands the establishment of the guidelines for LCC analysis and evaluation from the competent authority Korean Ministry of Construction And Transportation(MOCT). The objective of this study is to develop the improvement directions for LCC analysis and evaluation which are suitable to the public construction projects especially for the Design-Build and alternative bidding system in Korea. For this study, the LCC related raws and regulations, LCC analysis guidelines of public cooperations, actual condition of LCC analysis and evaluation which include, the elements of LCC, the estimation rules of the initial cost and the maintenance cost, the analysis standards of time value of money, etc. are investigated to provide the improvement directions for LCC analysis and evaluation.

Procurement system of public construction projects in Japan is changing with diversity in rapid pace. The quality assurance and risk management of construction projects should be more certain as the projects are turning into larger scale and more complexed. The clients in the public sector will want to make the relation of responsibility among the client, the designer (architects and engineers), and contractor clearer in terms of role and risk. Public-Private Partnership (PPP) is one of the methods for collaboration of the public sector and the private sector in public construction projects where the public utilizes the ability and suggestion of the private. Private Finance Initiative (PFI), Design-Build-Operate (DBO), market testing, designated manager system, outsourcing of tasks in local governments are well-known as examples of PPP in Japan. Indeed, there is an obvious trend that Design-Build (DB) is adopted in public construction projects in many countries including Japan. In this paper, the public construction projects in various procurement systems are surveyed and analyzed. They are not limited within the traditional procurement, Design-bid-Build, a separate order system of design and construction. Design-Build or PFI are adopted. In particular, contract by wide range including maintenance of equipment can be found. On the other hand, modification from originally typical PFI is taking place, such as concept design and project finance are removed from the roles and the tasks of the special purpose company (SPC) in PFI. Standard roles and tasks in a construction project are modeled in this paper.

This paper is concerned with the development case of CEA(Course-Embedded Assessment) design tool for engineering education accreditation operations department for CEA system implemented. Each university or programs are already devoting efforts to build research and CEA system for CEA applied to. In order to effectively apply the CEA studies for each program it is required and particularly, the preferred way to build an operating system is considered a difficult situation of the course unit. Therefore, this case study and to propose a method and procedures required to assessment the design basis for curriculum and program assessment unit in terms of the applicability of CEA, proposes a virtual application results. The information proposed in this case study is determined that could be used in the design for the outcomes and assessment of a variety of programs as one of the steps to build the CEA systems.

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.

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.

A dedicated CAM(Computer-Aided Manufacturing) system has been developed, which generated tool-path to machine Styrofoam stamping die-patterns in Chrysler Corporation. A previous process to build die-patterns was to "stick build" the pattern, in which stock is cut & glued together, and then the NC machining of part-surface shape completes building a Styrofoam die-pattern. The current process utilizes the developed CAM system, and almost removes the manual work, consequently reduces the overall lead time. The paper presents the overall system structures, tool-path generation, and some features of Styrofoam pattern machining.

This paper proposes a Product Data Management (PDM) system architecture that supports end-user computing for small and medium businesses (SMBs) in Korea to build and maintain efficient and sustainable information systems for their product development. Its open database with relational tables enables existing common application programs such as Microsoft office suites to access product data in PDM systems. In addition, the interactive query processor provided by database management systems helps design engineers to build ad hoc queries in standard SQL database language to response different data requirements during their product development. The PDM architecture with the open database allows design engineers or technical staffs in SMBs to build and maintain their application programs for product development by themselves. To show the feasibility of the proposed architecture, this study implemented a prototype PDM system based on the architecture and database, and represents real-world product data with the implemented PDM system.
