  • Value engineering (VE) of the construction project is classified into design phase value engineering and construction phase value engineering. Design phase value engineering must apply to over 10 billion public construction projects by government law. Therefore, the design value engineering apply to actively in construction projects. In contrast, the construction value engineering apply to a limited certain construction project. The reason is that construction value engineering process can not reflect practical demands quality. The construction value engineering can implement to positive impact through the feasibility verification for constructability. In this research, we propose a method of construction value engineering that reflect the practical demands. This method is experts alternative evaluation of using by GFI-based. And, this study was applied to the practical cases to verify the applicability of the proposed method. As a result, proposed alternative evaluation method were analyzed highly efficient in terms of applying the process as well as the method compare to the conventional method.

  • VE(Value Engineering) process and techniques are the systematic managerial tool for value engineers to help conduct VE study effectively. However, There is some difference between VE theory and practice in the domestic construction industry. Specially, function analysis appeared to be poorly recognized and regarded even as unnecessary in construction VE. It is needed to identify and enhance the problem areas to upgrade the VE practice. In order to investigate the current VE practice, a comprehensive literature survey and analysis were performed to obtain the trends and problems, related to the process and techniques. In the VE application of the domestic construction project, the study suggests some ideas and future study areas for the effective VE application in the construction industry.

  • It is increased concerns that review the design based on the economic efficiency, VE(Value Engineering), in construction industry. Also, the effectiveness of VE case study has reported very variously in the domestic and foreign construction industry. The phase of drawing idea VE process is important because of real cost saving effect. The design review checklist in the phase of drawing idea make more effective VE. The research suggests the method and process of design review checklist focusing on the construction work in this study. Also, it proposes the useful process with the exited VE procedure.

  • VE aims at reduction in a budget, improvement of function, structural safety and quality security for public construction projects. However, there is possibility for the structural safety and quality security review to be insufficient because related regulations are mostly composed of analysis on economic efficiency of design. In addition, due to the misconception about VE as a cost saving methodology, an alternative is being presented which still focuses mainly on cost saving, but with no objective evaluation of function related to cost. In order to improve this, the government adopted the reduction of life cycle cost and proposal of value improvement, and let people specify the cost and function of the original plan versus the alternative plan, and the value changes between them. However, it is written mainly into practical convenience rather than theoretical basis since a specific way is not suggested. The current method sets a different starting point by applying the attributional difference of function and cost. Furthermore, an evaluation standard for correlating is an important element in rational decision making for assessing and choosing an alternative. This paper analyzes the process and method of function & cost scoring when performing VE and suggests a mathematical normalization model in order to support rational decision making when selecting an optimum plan.

  • In the year of 1980 and 2000, the Korean government institutionalized the Value Engineering methodology in the construction phase and the design phase respectively. While design-phase VE have been applied to construction industry actively, which was institutionalized 7 years ago, construction-phase VE have not been applied to industry frequently, although it was institutionalized 25 years ago. On the other hand, at the time of social demands for VE is increasing, it has been pointed out that VE should be compatible with the delivery system. And the time of VE study, the operational management of VE study, and the maintenance process of the result of the VE study also should be considered. In this study, a scheme to improve VE methodology in the construction industry is proposed based on the literature review and the data analysis of domestic and foreign state of VE.

  • The ideas created by the execution of Value Engineering(VE) during design phase are usually proposed in a scattered way due to the characteristic of brainstorming. Because of this process, it is likely that similar ideas are proposed duplicatedly, and the created similar overlapping ideas may lead to different analyses and evaluations respectively. The efficient analysis/evaluation of the such similarly created ideas are not easy and the verification of the adequacy and objectivity of the ideas becomes harder and the objective evaluation gets more difficult as well as consumes much time. In spite of the perfect executions of preparatory step for idea creation, the difficulties in managing the similarly created ideas in quantity systematically result in the reduced reliability of the VE activities during design phase. Thus, this study proposes a process model for the efficient idea creation and management of the VE activities during design phase.

  • 2006년부터 VE 대상프로젝트가 확대되고, 기본설계와 실시설계단계에 각 1회씩 설계VE를 적용토록 규정되어 설계단계별로 VE가 각각 적용되는 프로젝트가 늘어나고 있다. 그리고 원가절감과 성능향상으로 프로젝트 가치를 높인 설계VE 사례도 많아지고 있다. 하지만 기본설계와 실시설계단계의 조건에 적합한 VE 수행방안에 대한 연구가 미진하고 참여자들의 경험과 이해가 부족하여 단계별 설계VE를 효율적으로 수행하는데 많은 어려움이 있다. 본 연구에서는 기본설계단계와 실시설계단계로 나누어 VE를 수행한 실무사례를 분석하여 기능정의와 아이디어 창출간의 연관관계 및 각 설계단계에서 기능정의를 수행할 때 발생하는 문제점을 도출하였다. 문제점을 해결하고 효과적인 설계VE를 수행하기 위하여 다음과 같은 개선방안을 제시하였다. 첫째, 설계프로세스의 흐름에 맞추어 기본설계에는 공간기능에 대하여하고 실시설계에는 부위에 대하여 기능정의를 수행한다. 이때 상위의 레벨에는 하위의 레벨의 기능정의가 연계되는 기능분류체계 (FBS : Function Breakdown Structure)를 제안하였다. 둘째, 기본설계와 실시설계단계의 기능정의를 수행하는 프로세스 (FDP : Function Definition Process)를 제안하였다. 셋째, 실시설계단계에서는 부위별 요구 성능 평가 매트릭스 (EFM : Element Function Matrix)를 적용하여 기능정의와 아이디어 창출이 연계되도록 하였다. 설계VE의 주요 부분인 기능정의 과정에 대한 문제점을 도출하여 해결방안을 제시함으로써, 보다 효과적인 설계VE의 수행을 기대할 수 있다.

  • Recent years, the construction projects of a world-wide have changed toward integrated evaluation considering all environmental and economic aspect for ecological construction.. The object of this study is to suggest the method and system for integrated analysis VE/LCC and LCA. In order to integrate and analyze environmental and economic aspects of alternative design elements, decision maker should handle simultaneously much information such as cost, document and drawing. This study presents applicative methods of WBS for integrated management of these information. Also, this study presents a decision support system that can manage DB easily by using VE, LCC and LCA analysis module separately.

  • Recently, Korean government promotes BTL(Build-Transfer-Lease) for their public construction project to apply private sector's experience and finance initiatives. Many of public buildings and civil infrastructure projects were planned to be delivered by BTL and it helps to continue public projects under tight budget conditions. Since the characteristics of BTL projects, creative ideas for the project function, performance and its LCC (Life Cycle Cost) become more important than usual public work project. This paper introduces the systematic "VE job Plan" application techniques for BTL project and shows the process. This study shows the application of "VE job Plan" for BTL project to help decision making and value improvement. Also, Project cost was estimated by LCC (Life Cycle Cost) analysis. Technical "FAST diagram"was developed and used to find major functions of the project. So, it helps to improve performance of functions and make creative ideas. FAST diagram also help to find relationships between functions and cost. A case study (Daegu Art Gallery BTL Project) was conducted using proposed "VE job Plan. Study demonstrates how value management helps save money and increase functional performance. Researcher found that project can save cost and improve performance of functions significantly by using appropriate VE analysis process at appropriate time.
