The growth of sensor and wireless communication technology enable us to monitor the status of things in real-time. There are many attempts to apply the real-time monitoring in various fields. Especially, the real-time monitoring in facility management fields has attracted much attentions recently. But it is difficult to apply recent technologies including sensor, wireless communication and Geospatial information technologies, etc, to the real situation directly. One of the reasons is that facility managers who are familiar with existing processes may resist the change induced by new technologies. So it is necessary to close the gap between new technologies and existing processes by improving the existing processes prior to putting them in the field. In this paper, we suggest the management process improvement focused on the district heating facilities.

BTL projects for educational facilities were conceived in 2005 to supply public facilities in a timely and efficient manner After the projects were completed in March 2007, proper facility maintenance has become an increasingly important issue. However, BTL projects are still in an early developmental stage, and the data on the maintenance and operation of such facilities are not yet available because the operation of the facilities has just begun. Accordingly, this study is conducted to derive maintenance processes and to specify maintenance items for the efficient maintenance of BTL educational facilities. Then, database on the maintenance processes will be created, and a maintenance system module will be designed.

our country school construction from 1990 year middle the facility expension for the improvement or education environment and the maintenance expense of various conservative construction for old education facilities is increasing. It accomplishes the each subject wild for business which maintains the training facility enterprise to be, the minute paragraph of information and deficient standard of information. It brings about the duplication investment a waste of the revenue source which is limited. Occurrence information which it follows consequently in business process and requirement must clear. We the maintenance phase of the education facilities understand, problem point and obstacle VIP analysis it leads it presents it does analyze. The improvement process model which leads a hereafter function for obstacle VIP extraction and information model construction must be accomplished.

To be Low Carbon and Green Growth, it is necessary that Long-Life Housing based on Green Technology is supplied. The main concern at the moment is developing Sustainable Housing relative to Life-Cycle or Life-Style of the residents, and the resident of Remodeling or Redevelopment. This study is aim to be Development of Maintenance Process in order to make steady dwelling when supplying Long-Life Housing that separates Support(Skeleton) and Infill different from the existing Short-Life Housing, and has durability, alterability, available remodeling, easy maintenance. Long-Life Housing should consider the maintenance about movement and variableness. In contrast, the maintenance of the existing Housing is regular maintenance, change and repair by damage. As well as Long-Life Housing should be demanded proper Development of Maintenance Process because of difference of Housing in concept, design and Construction. Therefore, this study looks into problems when applying Development of Maintenance Process in Long-Life Housing, and shows Development of Maintenance Process about the efficient Long-Life Housing for the manager.

It is critical to effectively change the measures of prevention from the breakdown maintenance proceeding an apartment housing maintenance task scope. It is necessary that systematization be performed for a series of tasks, such as facility inspection, diagnosis and replacement. In addition, it is preceded by establishing a standardization for maintenance work scope. Therefore, this study examined the problems related to public rental housing maintenance work scope to manage it more systematically. In addition, the study suggests a work process section for facility repairs, long term replacement and general maintenance using one on one interviews with experts to classify the occupants, management office and head office. This study's standard work system is expected to provide fairness and transparency in addition to improving the productivity in public rental housing maintenance via an efficiency promotion plan. In addition, it is used as the basic reference for developing a system of public rental housing maintenance costs and diagnosis actions. Finally, it is necessary to create improvements that provide a more objective work system standardization throughout the analysis of the productivity data according to the work flow and the review of the occupants, management office and head office in the future applications of the pilot site.

For effective building maintenance, the collection and management of various maintenance date such as work history information and material information is required. Despite the introduction of information management technologies and systems to reduce the amount of maintenance work of buildings, which have become larger and more complex, the maintenance information is not being utilized properly. As an alternative, research on the introduction and utilization of BIM is being conducted continuously. However, the BIM models generated at the design phase are not utilized in practice due to a lack of architectural maintenance information. This study proposed a COBie document prototype to support BIM-based smart maintenance tasks performed by building managers. In order to formalize various types of maintenance work procedures, a BIM-based maintenance process model is presented in two categories: inspection and maintenance. Among the BIM attribute data of the BIM model generated at the design phase, the parameters corresponding to the maintenance necessary information for each basic process are derived. Based on this, we proposed a COBie document prototype consisting of seven spreadsheets. The results of a case study confirmed that the KBIMS library-based BIM model created at the design phase without the maintenance information can be used at the maintenance phase.

Construction industry becomes large and complicated as that occurred in the construction processes and operations, and the growing social demand for more systematic and efficient methods of integrated management increases. Current facility maintenance system has been regarded as large labor-intensive and fairly stagnant, and faced on several issues including inefficiency in cost and time to collect and utilize various field information. Thus, this paper presents a maintenance prototype utilizing NFC technology and smart devices to efficiently collect and manage the field information in the course of the construction processes. By choosing dam facilities as a case study, construction data for dam inspection and maintenance were classified according to dam maintenance guideline, and database structure was constructed to incorporate with the NFC tags and smart device interface. The system prototype presented in this paper would improve the quality of the dam facilities maintenance system and provide business convenience and usability by contributing increased efficiency of field information management and sharing.

Based on the previous year's statistics, 37% of buildings in South Korea are aged over 30 years. As the number of the aging buildings increases, so does the need for maintenance. Building maintenance involves a significant number of works; the work of 'maintenance manager' accounting for the largest part. Currently, the maintenance history record is mostly in drawing or handwritten form which makes reviewing the data highly time consuming. Therefore, to improve the convenience of maintenance works and optimize historical data management, the existing maintenance process was analyzed. Problems were derived and a smart device-based automation model was established. In order to establish a smart device-based automation model, ① general flow of facility management process was analyzed and related articles were reviewed, ② current maintenance process was optimized, ③ functional block diagram of BIM Data, COBie Data, IoT, and AR-based automated maintenance management model was created, ④ a smart device-based automated maintenance management model was constructed, ⑤ finally, the above system was verified by testing the aforementioned model in the field site, evaluating the time required for the maintenance process and reviewing maintenance history data against the current one.
