실무기반의 시공VE PROCESS 개선

Abstract

The VE (Value Engineering) of a construction project is largely classified into the design VE and the construction VE. The earlier the VE starting point is, the better the effect is. Therefore, applying the VE at the designing stage is much more effective than the constructing stage to reduce construction cost and to raise the quality of a product. The VE should keep pace with a designing process. However, due to a lack of time, it is difficult to get a reliable effect of a VE application. It is vital to stimulate the construction VE to complement with the legislated design VE. The construction VE in Korea had been partly applied by private enterprises, but it has come into wide use since the design VE defined by the Law of Construction Technique Management. Revising locally performed VE examples for the last decade, those examples are all fragmentary introductions. Accommodating studies are mostly caused by the time limitation of VE activity, the lack of practical information, and the shortage of experts. Therefore, in-depth studies are hardly found in the category. The research from the point of view of literature, management, and system was possible to find the main reason of a construction VE’s inactivation problem. The reason is that the existing construction VE process could not reflect practical quality. Therefore, this study improves a process of the construction VE based on practice. The keys pillars of advanced construction VE process are an examination of interference of each step, a choice of the VE target based on a risk analysis, and an evaluation method using GFI. To illustrate an applicability of the improved process, the case study used the method to the sample project. The result of an improved VE process applicability shows better specification compared to the existing VE process, such as application procedure, application method, and connection to other tasks. Since the revised process reflects the characteristics of the construction VE executed in the field of value engineering, it is helpful for VE members to approach substantially.
