Value Engineering(VE) is an organized effort to create the most value through a functional analysis and creation of alternatives. Depending on the VE job plan, a VE Workshop must be performed in a certain place within a certain period of time. A VE Workshop, which is an organized activity that aims to create the best value through functional analysis and creation of alternatives, should be held in a certain place and at a scheduled time according to the VE job plan. In the Pre-Study, VE Study and Post-Study phases of VE, functional assessments, performance evaluations and idea evaluations are driven by variable management techniques and analysis methods, respectively. Generally, VE is executed for about 3 to 5 days in a particular place to create value. However, there are many problems associated with limiting all VE processes to a specific place and schedule. Moreover, in Korea, VE teams are required to finish all VE processes in a limited time because of the short duration of VE workshops, the necessity of which has been overlooked. Therefore, an efficient VE support system is required to resolve the problem of time and space limitations. In this study, a VE support system based on the Mobile environment was developed to support the VE Workshop process. This VE support system enables participants to review design documents, drawing sheets and all VE-related documents using mobile devices. After the Workshop, participants can conveniently rearrange the result(evaluation of function and ideas) at the workshop. Not only can the members of VE team can review the design documents, drawing sheet and all VE-related documents in the step before the workshop, but also the result(evaluation of function and ideas) of the workshop can be easily rearranged in the phase after the workshop under the developed supporting system using mobile devices.

Construction value engineering(VE) is often performed in the form of a short term review of designs, rather than during a regular workshop with a standardized work plan, and its application method is limited. Thus, tasks are performed by applying the method in reverse depending on the VE results, and function analysis, a key VE method, is omitted or only applied for the sake of formality. In addition, it is hard to expect great results from VE because of insufficient time and budget allowed to perform VE and a lack of understanding of VE procedures and methods. In particular, the methods used to store and reuse the tremendous amount of ideas and information created during the process of VE implementation is not systematic. Even the Korea Expressway Corporation, which has produced relatively systematic VE performance compared to other institutions, has had the above-mentioned problems. Therefore, this study aims to improve existing VE processes and suggest a method to efficiently store and retrieve VE information by analyzing the limitations of construction VE practice and the characteristics of VE for highway facilities as part of improving design VE performance.

VE is used as a powerful tool to add value to facilities by improving functionality and reducing costs. By identifying the client's requirements in the VE process and reflecting them in the quality model, the developed alternatives meet the client's requirements. However, there is no process to verify how the developed alternatives reflect the needs of the client through functional analysis, idea generation and evaluation. The purpose of this study was to develop, verify, and prove the effectiveness of a methodology for evaluating client satisfaction with alternatives developed during the VE Job Plan. The KANO model, which can identify the satisfaction and dissatisfaction of requirements in product planning, was set as a methodology for alternative verification procedures of VE, and was improved and applied to the purpose of this study. As a result, the alternative evaluation method developed in this study was found to be useful. It is expected that the KANO model will be used to evaluate the satisfaction of VE alternatives in the VE Job Plan analysis.

Value Engineering(VE) is the systematic activity to make a Alternatives for user's needs with an access by function analysis, creative thoughts, and the lowest life cycle cost. However, the current activity called VE is to make a Alternatives by experience and to make a report in similar to VE format. The right understanding of the concept and the process of VE is required for more effective Alternatives and VE activity with reliability.

The public employers are faced the mounting importance of decision process to settle the optimum VE delivery system of such public facilities buildings and etc. The elements of decision process of the public employer are formed in the various relationships of the concerned and when the projects are coming into effect, the decision process in the VE delivery method and the selection of contractor will be the name of the game. The decision process in the VE delivery method and the selection of contractor are created a case to be one and the same as well as initiates a consistency for the performance. However, the function and role of the public employer are projective accordingly to the organization of employer and the employer especially no system is equal to the capability of perfect evaluation and verification of the ability of the employer. Especially the lowest bidder policy that started with justification to increase the competitiveness and technical capability of the contractors through the completion in between contractors has been providing the hotbed for insolvency, irregularity and irrationality as a result. From this point of view it is declared that the buildup the edifice of supporting system in the process of decision to recover the mutual trust and respect of the concerned in the VE delivery system with the technostress and the systematization based on drawing the elements which affect the decision process of public employer.

Flame-retardant vinyl ester (VE) resin films were developed from the mixtures of brominated and non-brominated epoxy resins via esterification with methacrylic acid without reactive diluents. The films were used to fabricate carbon fiber (CF) prepregs via a hot melt impregnation process. The viscosity of VE resins suitable for film production was optimized by mixing low-viscosity bisphenol-A and high-viscosity brominated bisphenol-A epoxy precursors. Increasing the bromine content of the cured VE resin further increased the limited oxygen index (LOI) (39%), storage modulus (2.4 GPa) at 25℃ and residual carbonization (16.1%) values compared to non-brominated VE. Manual layup of as-prepared VE prepregs with subsequent curing led to the successful fabrication of CF-reinforced composites with high tensile and flexural strength. The results from the study hold high promise for a styrene-free, environmentally friendly VE composite process in the future.

Since the success or failure of VE projects depends on the capabilities of participants, including owners, construction managers, architects, general contractors and VE experts, it is important to follow systematic procedures. However, it is often the case that only a rough evaluation is performed, or the rough and detailed evaluations are integrated in actual VE tasks. In this case, it is difficult to analyze and evaluate the alternatives in terms of risk, even for the important alternatives. This in turn leads to the so-called returning alternatives where the alternatives proposed in the preceding stage are returned to the original plans in the following stage, and thus the repetitive work for the alternatives often decreases the efficiency of the VE task. In this regard, this study proposed a risk assessment process for VE alternatives in order to minimize the occurrence of returning alternatives based on the systematic analysis and evaluation of VE alternatives. It will increase the efficiency of VE tasks by reduces the number of regression alternatives.

The current VE activity is recognizing the VE object selection in job-plan simply as formal procedure. Therefore, many problems are happening in the process of selecting VE object during the preparatory stage. As a result of trying to analysis problems through literature review and expert interview, the problems were surveyed such as the lack of connectivity between preparatory stage and analytical stage, the temporal cost-based restrictions, and lack of recognition in VE team members in the existing method of selecting subjects centering on the high-cost field. Accordingly, this study suggested the improved method of selecting VE objects in order to solve this problem in the stage of selecting VE objects. An improvement method of selecting VE objects is what selects the secondary VE subjects by applying again Fish-Bone diagram and Worth technique based on the primary VE objects, which were selected by the conventional technique of selecting objects in the high-cost field. To verify effectiveness in the proposed improvement method, it tried to apply it to the actual case of the road construction VE project. As result of, the improvement method was analyzed to be considerably effective in comparison with the existing selection method of VE objects. Therefore, the Improvement method will contribute to increasing the VE performance.

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.
