Building Information Modeling(BIM) technology continues to develop and is now being applied to infrastructure facilities. As smart technology based on BIM is applied to the construction industry, the construction of the same data in a common environment is considered to be a very important step in various applications. This study was conducted on methods to establish an open BIM-based airport facility information common data environment. Therefore, this study develops the element technology to establish a common data environment for the integrated management of airport facility information, and aims to standardize data in the common data environment among various technologies and applications. In order to achieve the aim, in this study, the required technologies were derived by examining the common data environment and examining the civil engineering facility field and the case of integrated airport facility management. Through this, standards and development for information standard framework, information requirement level, BIM guidebook, and BIM library were developed in connection with national and higher standards. Through these standards, it is expected that the integrated management of various airport facilities will be efficiently carried out through a standard data platform in the future.

The purpose of this study construct water-facility Database and to develop its management system using GSIS. We used route system and event table that are data model in GSIS for the construction of water valves on water facility pipe. A water-facility management system using GSIS was developed and was actually applied for the city of Yosu and compared with conventional water-facility management systems in terms of workability, information searching cost, and database management efficiency. The system has also been compared with those of two other local governments in terms of functions, process time, and conveniences. The generalization of the work model for water-facility system was also attempted based on the data collected from three local governments and it was revised by the work model of the wide area water-facility system. The generalized work model in this study was compared with other two local governments' work models. The generalized work model will enable local governments to develop more efficient and economical water-facility management system by GSIS in future.

The main objective of this research is to develop an experimental educational facility management information system that will be used for maintaining existing educational facilities in the elementary, junior high, and high schools. The development is based on the nationwide development plan of the education administration information system. The system developed is accomplished by use of Map-application Information System(MAPIS), an applied commercial software that combines Geographic Information System(GIS) with existing Information and Communication Technologies(ICT) such as Database system, Multimedia methodology, and Internet system. In order to figure out the features to be improved in the system developed, the research interviewed the educational facilities management in the Ministry of Education and P Local Education Authority. The authors suggest the functional improvement of the system based on the interview results.

A power distribution facility map is composed of distribution facility information regions, cadastral regions and grid lines. In this map, our goal is automatic interpretation of power distribution region. For the goal, it is the first work to extract the power distribution facility region. In this paper, we propose a method to extract power distribution facility regions. The proposed method is consist of two phases, binarization phase and extending phase. The first phase generate a power distribution facility image using threshold value. The image contains many part of power distribution facility regions, but not all. The second phase extends thinned image which is generated by appling thinning operator to the power distribution facility image.

The existing drainage facility management system is not systematically computerized, and it is difficult to manage each drainage facility on-site due to insufficient information and location management. Currently, in the current drainage system management, repair technicians recognize the information of the drainage facility by recognizing the QR code at the site. These methods have difficulty locating QR codes in the field, and the problem is that they incur additional maintenance costs due to loss and breakage of QR code attachments. The GPS-based drainage management system proposed in this paper stores and manages each drainage facility's data including GPS information, allowing applications to use the location and information of drainage facilities based on user location data.

The USN is important in technique, unmanned observation using wireless network camera, detection technique that use intrusion detection sensor. But these encrypted data transmission and processing technique through sensor network, method of the staff's location recognition and arrangement aren't serviced still as a integrated system in facility security industry. This paper proposed that improve facility management, the staff present recognition and system efficiency using RFID, USN and wireless camera.

Safety accidents are increasing, such as changes in groundwater levels due to construction work or natural influences, or ground cave-ins caused by soil runoff from old water supply and sewage pipes. In addition, underground facility management agencies must make efforts to improve the accuracy of underground information through continuous investigation and exploration in accordance with the Special Act on Enhanced Underground Safety Management. Accordingly, in this study, we defined the configuration of equipment and data processing method to collect 3D precise exploration underground facility information and developed 3D underground facility information collection technology to ensure accuracy of underground facilities. As a result of verifying the developed technology, the horizontal accuracy improved by an average of 6cm compared to the existing method, making it possible to acquire 3D underground facility information within the error range of the public survey work regulations.
