This paper contains of descriptions of deterioration diagnosis of the surface and a coating layer for maintenance managements of large spatial structures with membrane structure. Membrane is a roofing material of the structures that its performance of durability including its performance of chemical resistance and corrosive resistance is considered to be highly important. In general, the items of diagnosis for maintenance managements such as membrane extensively include the diagnosis of deterioration of the membrane surface, of a coating layer of membrane, the diagnosis of deterioration between a coating layer and fiber, of overall surface of membrane, of the class of ropes, of reinforced belts, and of the cover of rubber. The object of this study that needs maintenance managements of the membrane with PVC and FIFE which are commonly used and shows the diagnosis results of deterioration of the surface and a coating layer.

A systemic building maintenance management is necessary to supply an convenience and safety environment by maintain the origin features for a building's life. However, the exist maintenance management system has some problems such as interoperability of information or standardization of data. In those reasons, a critical information for maintenance a building may be lost and changed. In addition, the data could be crashed or lost on a process of re-input or re-produce. This paper purpose the interoperability in exchanging data between design/construction and operation phases. In addition, this model will enhance the efficiency of building maintenance tasks through information quality improvement and data reproduction prevention.

This paper describes th on-line maintenance system with integrated graphic environment for building electrical equipments. This system is based on the pre-defined troubleshoot knowledgebase with maintenance information. And this system utilizes the database and knowledgebase for the diagnosis of facility and runs on the operator's requirement and response. The operator is possible of a detailed observation, an early detection of abnormal state, a properly operation and a rapidly arrangement of electrical equipments. Especially, this system is developed using the maintenance of equipments, if needed, be operated by non-expertise.

This study proposes an automated tilt measurement method using point cloud for buildings. The proposed method consists of two main steps: 1) exterior wall plane extraction, and 2) edge estimation and angle calculation. To validate the performance of the proposed method, the algorithm is applied to a target building, of which the estimated tilt values are compared with those obtained from a total station, a commonly used tool for tilt measurement. The result shows that most estimated tilt values are within the maximum and minimum ranges of the total station measurement, suggesting that the proposed algorithm provides sufficient measurement accuracy. Furthermore, the proposed method is shown to be automated and reliable as well as free from human-induced errors compared to the total station.
