Digital documentation is now becoming a must throughout a building process including design, construction, inspection, procurement and even facility management. The Internet is a backbone of such process, and web-based information exchange is the standard among other mainstream technologies. The current information management techniques, however, is heavily dependant on the server-side processing, which naturally results in the overload of the overall system. This paper proposes an XML-based approach in order to resolve such problems. A VE system was developed to demonstrate the efficiency of the XML solution, in term of efficient VE data management and fast decision making. also in this paper suggests 1) introduce XML based DBMS to improve data management efficiency and 2) introduce Mobile Computing to improve data accessibilities on sites.

Domestic construction firms make every effort to save cost and, contrarily, enhance quality for competitive advantage in the market. Structural work of building construction takes chaise of the total cost and schedule, thus elaborate planning and management of the work help to lead the project into a successful way. Therefore, the idea to save time and cost and enhance constructability securing quality and safety of the work should be developed after analyzing the designed documents and site conditions comprehensively in the initial construction planning phase. Value Engineering (VE) technique is introduced in the substructural work in this paper to save cost creatively and systematically in the design and construction phase. A practical VE model that is applied to the underground building work systematically is proposed to save cost and it applies to the actual project to confirm the effectiveness of the model.

The objective of Value Engineering (VE) is to derive the optimal value at the most efficient life cycle cost, comprising three stages: Pre-Study, Study, and Post-Study. In this study, we propose a method for information collection and analysis during planned site visit surveys in the preparation stage of VE. The 3D spatial model, created using a drone, facilitated observation and analysis of the study area from various angles, both from the center and the outside. Additionally, through the utilization of drones, we conducted on-site investigations of the research area's 3D spatial model, enabling a macroscopic perspective previously only feasible through a microscopic viewpoint during planned site visits in the pre-study phase. Furthermore, the utilization of actual spatial data obtained from observations allowed for real-time information verification during Design VE workshops, enhancing the efficiency and reliability of the VE project.

This study shows decision-making process for selection of cutoff wall on a wastewater treatment project. There are 10 different cut-off wall methods So, we examine the site to gather information for find appropriate methods. After using that information, 10 cutoff wall methods are reviewed for analysis. Through brainstorming, four alternatives are selected for design VE item. Following the standard VE process, we established performance criteria and evaluated function score(F) using questionnaire. The questionnaires, brainstorming and AHP method for weighting on performance criteria and evaluate function score increased the reliability of this selection process. Water Jet method, one of four methods, has the best function score(F=92.71) and the lease construction cost(as cost index 1,000). The value score also highest as 92.7, so we select the method. The result is value innovation type In addition, the authors try to calculate the environmental burden in selection process using LCA. We cannot conduct the full LCA as defined ISO, so perform Simple LCA In LCA result, the cut-off grouting has the least environmental burden as index 9.09E+01 and Water Jet method has following as the second. To selection best method to specific area and purpose, design VE/LCG process used as useful tool and it is needed to develop integrated method that evaluate VEILCC and LCA as one-set process.

Value can be defined as function divided by cost. The ultimate goal of VE (Value Engineering) is to simultaneously reduce cost and to enhance function in given projects. In general, there are eight phases (Selection, Investigation, Speculation, Evaluation, Development. Presentation, Implementation, and Audit) to perform VE. This paper presents analysis of important factors for VE in construction fields using QFD (Quality Function Deployment) technique. QFD was introduced in 1972 to help design supertanker in Mitsubish's shipyards in Kob, Japan and formally defined by the American Supplier Institute in 1987 as a system for translating consumer requirements into appropriate company requirements at every stage, from research, through product design and development, to manufacture, distribution, installation, and marketing, sales and services. The objective of this paper is to provide and analyze the trend on the viewpoint of efficient value engineering of field workers. The data are collected by questionnaires. The samples for this study are chosen from 13 companies in Korea during 2 months (2002. 7 ∼ 2002. 8). The results of this study will play an important role not only for the efficient value engineering but also for preparing of life cycle cost analysis.

과거 높은 수익 창출을 통하여 지속적인 상승세를 이어왔던 국내 건설 산업은 계속되는 경기불황으로 건설침체가 가속화 되고, 이로 인해 공공기관 건설공사의 발주물량이 점차 감소되고 있는 실정이다. 건설업은 이제 성장기를 지나 포화기, 더 나아가서는 침체기에 접어들었다는 전문가들의 의견도 나오고 있다. 이러한 상황을 타개하고자 발주기관에서는 예산절감과 품질향상을 도모하기 위해 가치공학 즉, VE(Value Engineering)를 활용하여 예산을 절감하면서 고품질의 건설 목적물을 완성하고 VE를 가치창출을 위한 주요한 도구로 활용하고 있다. 본 논문에서는 특히 가치공학이 전기설계 부문에 있어서 적용된 사례를 분석하고 가치향상 방안에 대하여 고찰하고자 한다.

Road on the urban underground railway has been repaired for several years right after completion caused by the settlement of backfill and the damage of utility lines, which demands the practical application of life-cycle cost on design of backfill. This study perform the VE and LCC Analysis to select a optimal method of backfill and present the models and factors of VE process in the consideration of specialists' opinion and judgement on the category of critical maintenance items.

The active promotion of construction technology application, aimed at cost reduction, construction time shortening, and performance enhancement during the implementation of Value Engineering (VE) in design, is underway. However, in the process of deriving VE ideas, it is common to simply reuse VE ideas from similar past construction projects, and the application of construction technology is often insufficient. Therefore, in this study, we intend to establish a database linking construction technology information with Building Information Modeling (BIM) models to activate the application of construction technology in the process of deriving VE ideas.

In campus project, "Barrier Free Design" is the essential part for the handicapped. It is necessary to make a quality model that choose effective design value engineering objects. So more effective models, this study examine requests of the university students. Checked items are classified into four groups that movement, guidable, safety and territoria parts, and each groups are also divided into detailed items for basic decisional elements. When basis points sets 10, it can be divided that movement parts 2.93pts, guidable parts 2.31pts, safety parts 2.41pts and territoria parts 2.35pts. in this results, we can make additive value and quality model for barrier free design in campus design value engineering.
