The traditional schedule management system provides project manager with analysis reports, such as progress control, earned value management and resource management, including schedule chart. However, the reports and functions in the traditional system are still limited in 2D concept. Recently, the scheduling method is using 4D concept that time of construction schedule is linked to space of drawings. This study presents the limitation of those systems and an improved method for developing 4D system through the comparative analysis of representative 4D systems that are developed up to date.

This study aims to development of web-based process management system for spatial data construction. For developing this system work classification of basic surveying was standardized and quality management method for spatial data was established. Production process and work classification system for basic surveying such as control point surveying using GPS, leveling, aerial photographing, digital mapping, topographic mapping, digital elevation modeling, aerial photographic DB construction and digital orthophotomap was standardized. The status of the output and quality inspection for basic surveying project were analyzed, and the elements of quality inspection and data format for the type of outputs were analyzed. Based on standardized and analyzed contents, web-based process management system was developed after database and process was designed. The process management system consisted of process management, quality control, metadata management, and system management.

컨테이너터미널에서 사용되는 하역장비의 에너지 소비패턴을 분석하여 효율적인 에너지 소비 관리방안을 제시하고자 한다. 컨테이너터미널의 하역장비는 전기에너지와 유류에너지 소비 패턴의 차이가 있으며, 이를 실적자료를 바탕으로 분석하였다. 또한 하역장비의 상호작용에 의한 대기현상을 발생과정을 분석하여 에너지 소비가 많은 애로공정을 도출하였으며, 하역장비 애로공정의 발생지점을 분석하였다. 에너지 소비 관리방안으로 처리량과 에너지 소비 상관계수 비교, 처리물량 변화 패턴 추적 관리, 하역장비 부족에 의한 에너지 소비 애로공정 관리 등의 3가지를 제시하였다.

Purpose of this study is to suggest some modules to integrate schedule and change control. The study has been performed through the process of literature review, effect comparison of being not integrated and integrated of the schedule and change control, and finally suggest new integrated modules. The results of this study are as follows: 1) Suggestion of a Predicted Change Information Control Module: This nodule can be used to assess the impact of changes in advance and to prepare counteraction. 2) Suggestion of a Change Information Control Module: This module is used to update current schedule for the realized changes. 3) Suggestion of a Revision History Maintenance Module: This module is used to record schedule and cost revision history and to analyze the overall change trend.

This study refers to development of WBS(Work Breakdown Structure) and Activity sample for integrated cost and schedule control system of sample bridge work in the field. The conclusions from this study may be summarized as following 1. It showed that the level of detail to network's activities depend upon schedule's intended purpose. 2. It is more effective 'activity to cost package model' than 'activity to resource model', for integrated cost and schedule control reflect the characteristics of domestic construction industry.

The purpose of this study is to develop a supporting tool for efficient management, at preconstruction phase, of the schedule risk that is able to generate at construction phase. The main contents of this study to develop a practical tool are as follows. First steel work was selected as a relevant trade and a risk breakdown structure focused on the process of steel work having large effect on total construction process was made. Secondly, the work flow considering schedule risk factor was made and schedule risks that must be managed preferentially through analyzing the grade of importance for risk was selected. Finally, based on above two procedure, the management form for schedule risk was developed It is necessary to accumulate abundant data for schedule risk for other construction process and to develop a manual and a schedule risk management system.
