In the past, there were problems in managing construction due to the lack of effective communication and sharing information between a constructor and an owner during construction works. To solve those problems, several major construction companies made great efforts to get a higher productivity through the systematic management, cumulating construction know-how. As a result of the endeavor, some of those companies developed the foundation of PMIS(Project Management Information System). However, it is thought that PMIS on the construction site was not effectively used in performing construction. Therefore, through the case of contractor's management system which is being used in 1-4 out field construction site in Incheon International Airport Rail of P construction company, this paper deals with the development of system supporting to the practical work of construction site and it'll provide to be the foundation of making effective PMIS.

This study analyzes the process of establishing BSC based strategic performance evaluation system of KOMSCO. This case could be a reference to other public institutes for BSC introduction and efficient BSC usage. Internal control system of KOMSCO has been improved by EVA system in 1999, BSC introduction and Job analysis in 2001 through 2002, and BSC performance evaluation system in 2004. KOMSCO tries to reflect BSC concept by inducing employees to cooperate selection process of CSF and KPI and by considering the organizational characteristics of KOMSCO in constructing it's performance indices. It is suggested that these processes are very important and should be followed by other institutes in their BSC introduction. By applying BSC, KOMSCO provides improvement in employees' understanding of strategy, performance management, and performance evaluation. KOMSCO' information system based on ERP and efficiently connected to EIS, KMS, and BSC seems to play an important role of BSC application. BSC system of KOMSCO is now in the early stage of application and needs to be evaluated by the efficiency of usage in terms of overall performance evaluation system, deduction system of evaluation point for excess accomplishment over target, and connection to budget system.

GIS is the system that has ability of integrating, managing, and analyzing the voluminous graphic and text data, which is adequate system to manage complex network of the underground utilities of urban area. A development of pipe safety management system is accomplished to construct efficiently a database of pipe line network and topographic data, create safety managing model, and estimate openly its safety by GIS. This system is constructed to evaluate easily pipe deterioration by the establishment of the geographic output system on it, search damaged objectives near surrounding area in a situation of destruction, and offer the information by which one can take quickly emergency. And also, it is constructed to prevent from accident occurring under work by presenting underground utilities and states of work.

Recently, construction management technology based on information technology is being changed from numerical information management to visual information management with virtual reality (VR) method. This study suggests a IDEF0 model for development process of VR system for the planning, design and construction phases of civil engineering project. And the simulation functions by each phase based on VR were developed by using the suggested IDEF0 model. The developed virtual construction system can be used as an effective design review tool by visualization of design information based on 3D object.

Cost, schedule, quality are the essential parts of success of every construction project. It is especially true in high-rise building construction. Among the construction components in high-rise building construction, curtain walls are very important elements for the project success because they take large portion of cost and schedule. However, curtain wall construction process are very complicated, where many entities including designers, suppliers, contractors and even maintenance contractors are involved. Therefore, control and management of their relationships and production process are critical. It is suggested that this can be solved by the concept of Supply Chain Management which is supported by the automated information technology with Radio Frequency Identification. Such concept is defined as 'Automated Life-Cycle Management System Based On SCM' and this study suggests rode map to establish the system.

Work breakdown structure (WBS) can be used as an information center in earned value management system (EVMS) for the construction project. Because EVMS results, such as schedule variance and cost variance, are analyzed for the selected WBS code, the role of WBS code is important in EVMS. This study suggests a methodology for organizing WBS map with a quadrant. It can represent the project organization collectively by work level in a coordinate system. And the study developed an EVMS tool based on the WBS map and this tool can visualize various attribute indexes of EVMS by color symbols. Those methodologies can be used for improving practical application of EVMS.

Actual construction data of completed projects can be utilized for the economic, time benefit of improving the efficiency on planning, designing, estimating and managing tasks in succeeding projects. But the lack of the system which accumulates and manages the actual data with standardized type, it has not performed well and stayed on early stage. It is required not only specific plan for the utilization of actual data but a construction information management system which collects and processes far-reaching data with standardized from based on facility. Therefore, the purpose of this study is to develop a construction information management system for Apartment housing ,which stored data along project feature database, actual cost database and actual database based on the Web. This effort can make an offer the clearness of dull construction market and the base of construction intelligence

한국전력공사 전력연구원에서는 2005년 전력IT 과제인 "전력계통 무효전력 관리시스템 개발"을 통하여 '전압관리시스템(VMS, Voltage Management System'을 개발하여 시범사업지역인 제주지역에 설치, 스마트그리드 실증사업에 참여하여 2013년 까지 운영할 예정이다. 전압관리시스템은 발전기 등의 순동무효전력원을 제어하여 계통 전압을 유지하는 중앙집중형 전압/무효전력 제어기이다. 이와 함께 한국전력공사에서는 제주지역의 전압/무효전력 특성 개선을 위하여 신제주변전소, 한라변전소에 각각 50MVA급 STATCOM을 설치하여 2011년 하반기부터 운영에 들어갈 예정이다. STATCOM 설비는 국부적인 전압/무효전력 개선을 위한 순동 무효전력원이다. 본 논문에서는 중앙집중형 전압/무효전력제어기인 전압관리시스템과 국부적인 전압/무효전력제어기인 STATCOM과 병렬 운전 에 따른 효과를 시뮬레이션을 통하여 검토하였다.
