  • Design Value Engineering (VE) has become an import part of the daily design process since it has been introduced in the construction industry. Design VE is usually conducted in the general and execution design stages respectively. In order to increase the effectiveness of the VE process, the outcome from the general design VE activities should be integrated into execution design. The outcome from the execution design should be used again for construction. In this study, a consecutive VE process model has been presented as a way to improve the current practice of design VE activities in the construction industry. In the presented model, follow-up activities are emphasized to increase values from the life-cycle perspective of a construction project. The model was tested in a case study of an actual design VE process. The result of the study demonstrates that the model can: 1) effectively incorporate owners requirements; 2) assist decision making in selecting better construction; 3) increase the interface between general and execution design stages; and 4) trace the value flow more efficiently. Overall, the study results indicates that a the consecutive VE process model can be effectively applied when construction project are contracted for the life-cycle management of construction projects.

  • To convert the construction industry from 'the high cost, the low efficiency' to 'the low cost, the high efficiency and value-added industry' and to enhance the performance and quality of products while reducing the cost, the related law and guideline were established and promulgated, which regulate that value engineering workshop during the preliminary design and the detail design stage should be a mandatory process. But VE practitioners are still confusing in choosing the proper value engineering process, because processes those are described in the various references use the different terms, steps and activities, even though they have their own specific characteristics. To resolve these confusions, the existing steps and activities of three kinds of the literature, four kinds of the organization's policy and other four kinds of study examples relating to the design VE were examined. And then, the differences and expecting problems were extracted through the comparison and analysis of those materials. After that, VE specialists' opinion through the questionnaire survey were grasped. Based on those studies the improved design VE Job Plan and activity statements were suggested.

  • 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.

  • Recently, construction projects are very complicated and diverse such as high-rise buildings and big bridges, etc. These complicated projects call for a system which can effectively generate productive ideas and activities. Value Engineering (V.E.) activity within construction projects is a necessity for systematic design management and to improve construction ability. This need in the construction industry has required a regular implementation of VE into construction projects. For this reason; America, South Korea, and some other nations have adopted VE applications which control the baseline investments of the construction projects. The process of VE activity is a preferred system and a reasonable alternative. In particular, idea generation within these projects is an important stage in the VE job plan. In this study, VE idea patterns are extracted through best practice analysis from VE cases of road construction projects. Next, we suggest an idea hierarchy model to be used in conjunction with VE idea patterns. This model is supported by reasonable idea generation in VE activity of construction projects. Finally, this model could possibly be the outcome of successful VE results.

  • The study investigated the effects of dietary Vitamin E (VE) on nitric oxide (NO) metabolism, immune function and analyzed the correlation between NO free radical and cytokines (IL-2 and IL-6) in broilers. One hundred and fifty 2-week-old broilers were randomly divided into three groups. Control group and lower VE ($VE^-$) group were provided with a basic diet supplemented with 12.55 mg/kg VE and 2.55 mg/kg VE for 30 days, respectively. Higher VE ($VE^{-}-VE^+$) group was supplemented with 2.55 mg/kg VE in the first 15 days and then 32.55 mg/kg VE in the next 15 days. Five broilers in each group were then sacrificed on the 5th, 10th, 15th, 20th, 25th and 30th days, respectively, and the content of NO free radical, superoxide dismutase (SOD), glutathione peroxidase (GSHPx), malondialdehyde (MDA) and cytokines, IL-2 and IL-6, were measured. The results showed that lower VE could decrease growth performance of broilers while higher VE could increase growth performance and eliminate differences resulted from feeding lower VE dietary in early stages (p<0.05). Compared with the control group, lower VE could increase significantly NO and MDA concentration, and increase IL-2 concentration in serum (p<0.05). Higher VE could significantly increase activities of SOD and glutathione GSH-Px (p<0.05). IL-2 is positively correlated with NO in heart (p<0.05) and IL-6 is negatively correlated with NO in liver (p<0.05) and heart (p<0.01). These results indicate that dietary VE could regulate antioxidant capacity and NO metabolism of broilers and higher VE-supplemented diet could directly decrease production of IL-2.

  • Construction VE activities has occupies an important position as a key tool of the project in terms of budget and performance improvements. Reflecting this situation, VE application scope is being expanded than before. Thus, construction projects are required the continued research and development for effective use of construction VE. VE target choice method is the central part in the construction VE work. But, this has a problem with low utilization in practical terms. Accordingly, this study was developed the new methodology(PVTCM) for VE target selection of the construction VE work. Its contents are as follows: First, to analyze practical problem for VE target choice method through VE practical data. Second, to extract the high potential VE object based on the cost model and ideas similarity by excellent VE cases analysis. Third, to implement standardized VE object item by using affinity diagram for each construction type items. This research were conducted to experts interviews for comparison analysis with the cost model as one of a representative target selection method. As a result, proposed method were implemented significantly higher performance in terms of practical effectiveness than conventional method.

  • Although the importance of creative thinking is rapidly increasing in the new century, the generation of creative ideas and its application in the construction industry have been considered relatively difficult. Thus there have been a few studies on the subject that how to apply creative thinking tools with empirical evidence in the construction industry. Value engineering(VE) has been widely applied in the design phase of construction projects due to the government regulation, Brainstorming has been the most prevalent idea generation techniques in the VE activities during the past several decades. Contrary to popular belief, the performance of brainstorming is not so good. It is known as the brainstorming myth. This paper proposes the business creativity codes(BCC) as an alternative idea generation tool in the design phase VE of construction projects. In order to examine the effectiveness of the BCC, 50 successful field cases awarded in the design VE competition of government agency are used. The result shows that the BCC can be used as an effective idea generation tool in the design phase VE construction projects.
