The construction information used in the design and construction phases are being gradually changed by 3D objects based on virtual reality (VR). This study developed an algorithm and computerized system to visualize layer object simulation that can be used in the pre-design phase. Layer object simulation enables designer to review expecting problems, which can reappear in real construction site, by building construction structures in a VR system. This function can be used as an important tool of virtual construction 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 gas line safety management system is accomplished to construct a database of gas line network and topographic data, create safety managing model, and estimate openly its safety by GIS. This system is designed to evaluate easily the damaged facilities in case of gas line explosion by the establishment of the geographic output system. It is designed to trace and present efficiently closed valves and interrupted facilities of gas when gas line breakage occurs, and offer the information by which one can take quickly emergency. And also, it is constructed to prevent from accident occurring under construction work by showing underground utilities and states of work.

The participants of steel works should exchange a variety of information with others through documents. However construction steel works in the multistage contract system has a difficulty in exchanging information through the documents promptly. So if the trouble as change orders arise, conducting steel works will take much time, and the participants may not discuss the trouble sufficiently. Consequently this study improved the current business process of steel works. And this developed business support system(XCOS) based on XML so that participants of steel works achieve a successful management of steel works through conducting business rapidly and correctly.

The study presents work information classification system of apartment house which can organize all construction management services throughout the planning and management of a construction such as the decomposition of the design process, the assembly of construction process and cost estimating, etc. In addition, the study suggested a way to connect work information classification system based on a relational database in working order and built a conceptual model for automated cost estimating by utilizing established data base. A conceptual model for automated cost estimating will resolve the fundamental problems of the existing cost estimating system and will be able to take advantage of scientific cost estimating system at the construction site of apartment house.

In order to achieve the best performance of a project, uncertainties involved in the building construction process need to be identified in the planning phase of the project. Risk management plays a significant role in construction to minimize risk occurred due to uncertainties of a project. Although the importance of the risk management has been known to the construction industry, a more effective system should be developed to meet the demands of the industry. The purpose of this study is to develop the effective risk management system for scheduling the construction processes. The study provides a tool that can optimize the management system which would assist managers to identify schedule risks in the planning phase of the project.

This research has been Initiated to provide an effective management tool for budget control of the public projects using EVMS. Barriers to implementing the tool for the domestic public projects are identified : no PMB (Performance Measurement Baseline) for budget control, management by BOQ(bill of quantity), no systematic planning and control. To eliminate these barriers, an integrated cost and schedule management process model using EVMS is proposed. This model is composed of six sub processes : organizing, scheduling, budget allocating, establishing PMB, managerial analysis, change incorporation.

Currently, the quality management, safety management and environment management of domestic construction work does not form a infrastructure for integrated control which have been developed according to the unique characteristics based on respective the law. In other words, the quality manager and safety manager of human resources is set to a legal arrangement personnel, but environment manager of human resources is not. In addition, quality management standard is to perform the work to PDCA(Plan-Do-Check-Action) system which is reflected in all of the requirements of KS A ISO 9001 standard, but safety management plan and hazard harmfulness prevention plan are not properly reflected P(Plan), C(Check) and A(Action) system and focusing on only 4 section Do(D) in KOSHA 18001 standard requirement. Moreover environmental management plan is not even established requirement. Through examining the operation practices of an advanced nation prior to building the integrated control standard for construction work qualify safety.environment, the possibility of applying domestic is reviewed, and then this study is going to research the operation practices of Singapore.

To manage a construction project efficiently, it is essential to ensure the practical usage in construction management. The purpose of this study is to develop a practical model, which will increase the efficiency of management. The followings are the method of this study: (1) Establishing a breakdown structure based on integration of CBS and WBS which is well acquainted (2) Developing and systemizing managerial standards and processes on such activities as calculating and marking progress rates & schedule, summarizing cost by activities level, making out project analysis reports. This study shall contribute to raising the efficiency in construction management after being verified in a pilot project and being developed into construction management system.

국가물관리기본법에 의거하여 통합물관리 정책에 부합하는 농어촌용수 계획 및 관리를 위해 유역 및 용수구역 단위의 농업용수 공급 및 수요 분석이 요구되고 있다. 현재 농업용수는 개수로 방식 용수공급체계 및 수문 직접조작에 의한 용수배분체계로 공급량 대비 사용량의 비율이 48%에 불과하다. 또한, 농경지 상류와 하류의 공급량 차이가 크게 발생하며, 경지면적 감소가 공급 필요량 감소로 연결되지 않는다. 농업용수의 경우 기존 국가유역수자원 모델 (K-WEAP, MODISM)을 통한 물수지 분석시 순물소모량 개념의 회귀수량 산정으로 공급량과 회귀량의 왜곡이 발생하고 있으며, 이에 따른 공급량 왜곡, 유역내 복잡하고 다양한 농업용수 공급체계를 하나의 가상저수지로 단순화함으로서 유역내 들녘별 농업용수 과부족 분석 불가능, 하천과 저수지 공급 우선순위 현장과 불일치 등 농어촌용수구역의 특성 및 실제 현장을 반영하는데 한계가 있다. 본 연구에서는 기존 물수지 분석 모델을 개선하기 위한 농업용수 유역 물수지 분석 모델의 방법론을 제시하고 시범지역 적용을 통한 검증 및 적용성을 평가하고자 한다. 경기 안서 농촌용수구역을 대상으로 농어촌공사 및 지자체 관리 저수지, 양수장, 취입보, 관정 등 총 106개 개별 시설물 자료를 구축하였으며, 39개 지구로 세분화하였다. 한국농어촌공사의 계측 공급량 기반 수요량 및 개별 시설물에 대한 물수지 분석 후 지구 단위, 소유역 단위, 표준유역 단위의 상하류 및 시설물을 연계한 유역 물수지 모델을 제시하고자 한다.
