This study is aimed at developing a web-based management system of maintenance historical data, for effective maintenance performance and smooth exchange of information and communication between public facilities and public educational facilities managers. The current management state of maintenance historical data and its business process were investigated and analyzed, through interviewing with the persons in charge of managing each facility, by recognizing problems of maintenance historical data management that is able to be applied as a basis to judge facility deterioration and performance. In addition, this study suggests a maintenance historical data system of which DB may be applied to the practical business, by reflecting requests of the persons in charge of managing facilities, setting up the scope of system usage by facility, business phase and level of facility managers, and establishing a maintenance business process system.

우리나라의 물관련 정보는 국토해양부 및 관련 기관에서 구축 및 운영, 개발 중에 있다. 이러한 시스템들은 치수, 이수, 환경 및 생태분야에 다양한 정보를 제공하고 있으나 제방에 관련된 다양하고 구체적인 정보를 획득하지 못하며, 시스템 DB간의 상호 연계가 어려운 실정이다. 따라서 제방에 대한 DB관리 및 향후 제방의 안전모니터링을 위해 정확하고 다양한 제방관련 DB구축이 요구된다. 이러한 제방관련 DB구축을 위한 과정은 다음과 같다. 제방제원 및 관리정보의 DB구축을 위하여 국내에서 수행하고 있는 사업인 하천일람의 "하천이력관리체계", 유역조사사업의 "WAMIS", 하천정보를 제공하고 있는 "RIMGIS"의 관련 자료를 분석한다. 기구축된 시스템과의 연계를 고려하여 물관리정보 표준과 RIMGIS 관련코드를 적용한 도형 및 속성 정보의 테이블 설계를 수행하며, 기구축된 시스템의 제방관련 수집자료 DB 및 관련 항목을 추가함으로써 제방제원 및 관리정보의 DB를 구축하도록 한다. 또한 향후 제방의 안전모니터링을 위한 관련항목을 포함하여 제방 유지 및 보수에 활용될 수 있도록 한다. 제방관련 DB구축은 치수시설물 안전모니터링의 기초를 마련하여 홍수방어 및 관리시스템 구축에 활용되어 인명 및 재산피해를 절감하고 기술수준을 향상시킴으로서 홍수 재해로부터 안전한 국토 건설 및 국민의 삶의 질을 향상시킬 것이다. 이러한 제방관련 DB구축은 기구축된 시스템과 연계하여 국가 홍수관리 시스템 구축, 치수능력증대, 장래유역단위 통합홍수방어 및 관리기술 개발에 기여할 것으로 판단된다.

Underground facility DB that is constructed by NGIS project need efficient management methodology, because falling-off in quality was worried by confused of existing management affair and management affair of computerization environment. Through analysis of existing management affair, underground facility DB and management system decide that modification/renewal factor of underground facility DB and subject affair Through modification/renewal factor of underground facility DB, developed underground facility DB management methodology using MMS. Result that apply developed management methodology to subject affair, existing affair environment improved to computerization environment and Could improve underground facilities DB authoritativeness.

This study is intended to build research for ways to utilize material information in the design and working business for public works. The contents and results of this study can be classified into object-oriented DB application to bridge construction and object-oriented DB utilization of civil material information. First, application of object-oriented DB to bridge construction 1) constructs the work unit of classified work table as an object(Each object constructs material information on the statement of quantity calculation as data), 2) constructs object-oriented DB for superstructure and substructure of PSC Beam bridge, 3) leads to the research for ways to utilize materials by developing 3D bridge prototype with REVIT structure. Secondly, ways to utilize object-oriented DB for civil material information identified the possibility for utilizing it in making 2D drawings for design work, preparing materials list, analyzing structure for working businesses, selecting and purchasing materials, managing process and maintaining. It is suggested that the results of this study should be applied to all bridge constructions through test-bed and additional studies so as to secure the credibility of the results of this study.

Recently, amount of High-Rise Mixed-use Building is Increasing based on Preference of comfortable residence and good view. Government policies were turned to prefer about High-Rise Mixed-use Building because of decreased real estate Condition. But these changes have revealed that it has many maintenance problems for example- efficiency, economic, environmental problems. This paper suggests that the Database System based on various alternatives and real case. And it will be a tool in the scientific decision and value analysis from the facility management to make optimized decision.

The architectural drawing, construction project specification, etc. are included in the contract of a documents. However, construction project specification, for being documentation, is not utilized to such an extent. The reason is that specification information is difficult in collecting information in relation to the architectural drawing, material finishing list and other architectural information. Therefore, an integrated model, which can be associated with other architectural information, is needed, and a DB based on this integrated model must be established in order for it to be utilized in design, construction, and management. The DB, which is established through this process, must be updated according to modification in design, and construction. Furthermore the specification must be in document on the web for reference. Consequently in this research, the structure of integrated model has been introduced, and it has made the search and preparation of the integrated model on the Internet, using the specification information DB established for the mutual reference of DB, possible. The improvements of construction project specification standards are expected by this system. Also, it will bring about Improvements upon claim prevention, and design, construction, management qualities. Furthermore, it will make the use of information more convenient in practical business such as order agency, design service and building site.

In our thesis we introduce case study for qualifying university graduates system for efficient maintenance. First, we find out factors to make maintenance difficult and present solution for them. Second, we convert system architecture from algorithm-oriented to driving-engine-based, design DB schema, develop algorithms for important components of proposed system, and implement them. Through results of system operation, we show that our system can reduce maintenance cost fairly.

Retaining wall is a constructed structure in order to construct road, rail, building for effective use and obtainments of the limited ground. Recently, many kinds of research have been actively developed for a standardization and information to the maintenance and management of bridge, tunnel, road. With the works of database construction of that, many kinds of data with respect to statistics is cumulated. Database work of retaining wall is wholly lacking and lagged behind in the works of database construction. This paper suggests classification system on inspection data. On the basis of that, code work with classification system was practised and DB program of inspection data of retaining wall was developed. And input work for a data of maintenance and management was practised. The purpose of this paper is to suggest a kind of statistics data and investigate a characteristics of inspection using statistic data on retaining wall.

The inspections that are being done on current bridges in our country are made to go through a process of being recorded on the management system and then converted by the computer. This has deteriorated the credibility of manual-analog types of data, inefficient care of information, and produced potential problems of the structures of bridges through subjective evaluations. In order to solve these troubles, this research has aimed at effectiveness, management, and convenience so that the inspector at the actual scene of the bridge structures will be able to achieve the primary purpose of infrastructure safety through precise supervision. To assist this, this study has suggested a state of the art IT intellectual management system that has applied RFID. This system has been designed to decrease the inspecting time on the actual scene, which will provide more time for efficient inspection and by using the converted DB, managing and utilizing high quality data will come naturally and through the objective evaluation, it will be possible to make exact judgments of the structures of the bridge. Also, regardless of the location, it has been found that the work performance was excellent through highly effective management.

국내 건설공사의 기획 설계 시공 유지관리 전 단계에서 발생하는 방대한 정보를 제공 중인 건설CALS시스템은 국토해양부 뿐만 아니라 건설사 및 1,400여 곳 이상의 건설현장에서 사용 중인 시스템이다. 그러나 건설CALS를 구성하고 있는 단위 시스템들의 개발 시기 및 주체가 달라 통합 기능개선 운영 단계에서 DB의 논리적 구조가 복잡하게 변경되어 데이터 누락, 처리속도 저하 등의 문제가 발생하고 있다. 이에 본 논문에서는 건설CALS를 구성하고 있는 4개 시스템의 DB를 분석하여 개선이 필요한 항목을 도출하고 취약한 부분의 개선방안을 제시하였다. 제시된 방안은 DB시스템을 운영하는데 있어 가장 기본적인 방법으로써 쿼리문의 처리속도 및 DB장애 발생 시 복구능력 향상 등을 통해 시스템의 안정적이고 효율적인 운영이 가능하다.
