It is very important to manage efficient data for safety and maintenance of those constructs. Estimation for structural safety can be evaluated by using data that surveys various structural durability and safety elements. so, it should be based on synthetic and efficient data that includes a variety of related safety elements obtained from a structure. It will subsequently be managed properly and economically. Accordingly, we will approach efficient maintenance management using a Geographic Information System (GIS) with data from structural-safety diagnosis and a Global Positioning System (GPS). In this study, we noted that by using the data that measures the factors (crack, incline, settlement etc.) of various structures as evaluate safety degree. And the horizontal coordinate variation/time of structure was monitored using the GPS easily.

This study deals with the procedure of safety improvement, productivity increase, and tact-time reduction through setting up the system about preventive maintenance. Actually, it is hard to establish and carry out preventive maintenance, even though we recognize the importance of the system concerning time, cost, labor, and so forth. In this study in the viewpoint of cost we are for achieving maximum efficiency by change and reduction of planning process adapted to the special work group. At first we briefly will mention the kind, the necessity, and the concept of preventive maintenance, and then divide the equipment used in the assembly line into the two whether it is necessary or not by way of estimating the breakdown loss, comparing with general establishment of preventive maintenance and modifying it to the case. At the second step we will establish the operation system of plan management related to production and quality in the special case. Check period and category will be set by dividing the assembly equipment into LCL and Focus in the third step. The forth step will contain the operation procedure in detail. And then we must make check and repair record periodically. Finally, on the basis of the record the selection of checking of significance will be conducted. This results in safety improvement, tact time reduction, and productivity improvement.

현재 국내외 BIM을 도입한 사회기반시설 적용 사례는 BIM 시각화를 기반으로 하는 설계 및 시공단계에 제한되며 효율적 운영을 위한 설계, 시공 정보 활용 방안에 대한 연구는 매우 미미하다. 본 연구는 최근 국내 경제 발전에 많은 기여를 하고 있는 산업설비군 중 운영 및 유지관리 능력 향상이 필요한 하수처리시설을 대상으로 BIM 기반 통합 유지관리 프로토타입 시스템을 개발하였다. 본 연구에 사용된 주요 연구 방법으로는 시스템 개발 순서에 따라 진행하였으며, 최종적으로 개발된 프로토타입 시스템의 현업 적용 가능성을 판단하기 위하여 4가지의 대표적 유지관리 시나리오를 제안하고 산출물을 통해서 문제 해결이 가능함을 보여준다. 최근 상하수도시설의 자산관리 개념 도입 노력과 유역기반 운영 및 유지관리의 정책 및 제도 적 변화, 그리고 국내 상하수도 기술력의 해외시장 진출 필요에 따른 운영 및 유지관리 능력 고도화를 위해 본 연구결과가 일조할 수 있기를 기대해 본다.

The repair and maintenance planning is the principal transaction to prevent from the degradation of apartment buildings to prolong their lives. Various building components as part of living area should be maintained properly and timely before critical defects are realized, then the building life might be extended until the limit of its usability. In other words, various building components such as utilities, finishes and structural members are needed to be repaired and replaced in different time interval after completion. To do this systematically, a maintenance management system for Long-Range Planning (LRP) needs developing. The LRP should be figured out based on the forecast of repairing and replacing cycle of building components according to work trades. And the precise forecast of repairing and replacing time of the components helps to enhance the usability of the developed system. The purpose of this paper is to suggest a system with which apartment building managers carry out the tasks of periodical check, diagnosis and replacement of building components based on the maintenance calendar. By using the system, they can easily forecast repairing and replacing time of the components with the consideration of life cycle of building materials and build the LRP.

While the environment of usage of information and technology is getting stable and technology is being developed more deeply due to the globalization, making information, standardization, in order to make a fast response to the new industry strategy and business environment, mutual communication and management of correct and fast information are focused on as fundamental elements of keeping competitive power. Accordingly strategic development of urban transit operation organization, storage of information technology of urban railroad, and buildup of standard information infra are very important, so that computerized information system has been built up standardizing efficient maintenance framework of urban transit facilities. To maintain these facilities efficiently, storing the real-time information by standardizing the maintenance organization and building up computerized information system are very important with management of information history of existing maintenance work. Therefore, for the efficient maintenance of track system among urban transit facilities, standardized facilities classification and definition of management elements, and the plan of designing and building standardized database about track. system through standardizing technology resources are described in this paper.

The purpose of this study is to analyze elemental maintenance costs for educational buildings. The adapted research method selected three school buildings in Seoul as BTL projects. On the basis of the selected case, the study suggested a model to establish a system for each parts and to estimate analyzed maintenance costs through that system. According to the analysis, the study proposed a partial maintenance costs standard and analyzed proper maintenance costs. The results of this study are as follows 1) The system is divided into 8 large-groups and 24 small-groups for the analysis elemental maintenance costs. 2) The average rations followed by analysis of partial maintenance costs of the three school buildings are as followings, the total maintenance costs are analyzed 3,992 million won and each part of average rations is exterior of building 10.9%, interior of building 41.58%, electricity & fire fighting facility 14.22%, water supply & healthy facility 11.39%, heating & water supply facility 12.93%, landscape 6.3%, civil engineering works 2.69%.

This research is carried out to investigate the Condominium Management System of the states of California and Hawaii, and to examine the similarities and the differences between the Korean Apartment Management System and the American Condominium Management System. The research indicates: first, in Korea the management of apartment units is the Commission of the Representatives of the Occupants, while in America the management of condominiums is the Association of Apartment Owners, an organization of condominium owners in America. Second, it is required that apartment developers should submit such a document as the Public Report in America, which explains various matters concerning legal rights on condominium buildings and the outline of the buildings, to the authorities concerned in Korea. It can help the authorities to accumulate management techniques of the apartment complex, which could efficiently be used in practicing and planning city housing policies. Third, each apartment's management company in Korea is bound to make long term plans for maintenance based on the Housing Law. It is, however, difficult to reserve an adequate amount of money for the reserve fund, because its use is decided according to the maintenance rule which has a criterion different from each and every apartment management. Concludingly, an amendment of the Housing Law in Korea is required, in order to reserve at least 50 percent of the estimated sum of maintenance expense in future like Hawaii State in America.
