The risk of a fire in a building is closely related to the usage of the building. In particular, all fires that occur in a building are not risky to safety of human life, and it is associated with the combustion area and the increase of total floor area of the building. Therefore, this study focused on safety of human life in terms of the statistics of fire with considering the aspect of growing fires and analyzed the statistical data of fire for 10 years. As for the analysis on fire, the time of occurrence by usages of buildings, frequency of occurrence and the ratio of casualties etc. were analyzed. It is expected that results of this study could be used for evaluations on a variety of parts in terms of design, construction and maintenance of buildings.

Size of building has a direct relationship with building cost, energy use and space maintenance cost. Therefore, minimizing building size during a project development is of paramount importance against such wastes. However, incautious reduction of building size may result in crowded space, and therefore harms the functionality despite the fact that building is supposed to satisfactorily support users' activity. A well-balanced design solution is, therefore, needed at an optimum level that minimizes building size in tandem with providing sufficient space to maintain functionality. For such design, architects and engineers need to be informed accurate and reliable space-use information. We present in this paper a conceptual framework of an agent-based space-use prediction simulation system that provides individual level space-use information over time in a building in consideration of project specific user information and activity schedules, space preference, ad beavioural rules. The information will accordingly assist architects and engineers to optimize space of the building as appropriate.

Laws, administrative rules, and task manuals have been revised to build a modern river maintenance system in Korea for the last decade. And various researches and technology developments have been carried out to resolve related issues. However, the recent enactment of the new Act and the catastrophe of flood damage in 2020 have accelerated more emphasis on the reorganization and reinforcement of the river maintenance system in terms of political and social aspects. In this study, we suggested promising directions for strengthening the technical and institutional competencies of river maintenance with respect to policy, R&D, planning, and technology. The open discussion was held with the participation of industry, academia, research institutes, and government officials, and all participants conducted the related survey to collect their opinions effectively. These results are expected to be used as a reference to secure the justification for integration of government organizations, planning of R&D, the introduction of new river maintenance, and related technology development when reestablishing and reinforcing the river management system in the future.

The importance of using construction data is increasing in accordance with the recent trend in the smart construction. However, construction project and maintenance information is distributed on the web, and the existing BIM(Building Information Modeling) information exchange and linking method using IFC(Industry Foundation Classes) cannot support connection with BIM data and web resources. This study aims to establish the BIM-based port facility data integration system using linked data(LD) technology in order to integrate BIM and heterogeneous data in the port maintenance domain. To this end, the port BIM-based ifcOWL and port facility maintenance ontology were designed, and LD was built for the BIM and maintenance information of Busan New Port 2-1 Pier3, a BIM pilot project. In addition, service prototypes such as search, statistics and SPARQL(SPARQL Protocol and RDF Query Language) endpoint functions were implemented using the issued LD. The LD-based information utilization system is expected to improve the reusability of information by converting the existing closed information system into an open system and BIM and maintenance data as a web resource in a standard format.

This research is to analyze the characteristics of housing remodeling behaviors within detached houses that located at three small cities in the central part of Korea. The characteristics indicate similar aspects of maintenance and improvement behaviors in the occurrence time and space, while space alteration shows different aspects. In the frequency of occurrences, maintenance behaviors occurring in the point of building maintenance and preservation is performed most actively, the next is improvement behaviors, and space alteration behaviors is the lowest frequency. Type of remodeling behaviors shows the characteristics that maintenance behaviors are active in served spaces(bed room space, family living space) while alteration and improvement behaviors occur more in servant spaces.(household working space, outdoor space and sanitary space)

To maintain the public office buildings, the related government employee uses cost under the limited budget. it is difficult to execute the budget as is assigned to maintenance items with contemplating the characteristics such as frequency, cost/item, weighting factor, and etc. As a precedent study about this cost-efficiency model, this study is intended to show the expenditure trends, frequencies, and cost distributions of maintenance items for the development of cost-efficiency model by analyzing time series data from the surveys on maintenance costs of the selected public office buildings.

This paper aims to present the basic data to establish resonable building maintenance standards by investigating and analyzing the actual conditions of maintenance for service facilities and the problems due to the situation. The subject buildings of investigation are 10 stories and above off ice buildings in Seoul. The results obtained from this study are as follows. 1. The equipment service life related to air-conditioning system is known as around 9years in case of breakdown maintenance and around 13 years in case of preventive maintenance. 2. The total mechanical room area against the total floor area is $4.40\%$, and the ratio of air-conditioning room area is $1.78\%$ on an average.

User's demand, as a maintenance for durability of construction and a comfortable life, and an incentive systems for new waterproofing system incite waterproofing company to evolve new waterproofing system that is upgraded waterproofing quality by getting advantages for the existing waterproofing systems. There are seven new waterproofing systems for building roof to be authorized from Ministry of construction & transportation. Those are multi-layers waterproofing system, and five of those are the insulation type. A trend of new waterproofing systems for building roof is multi-layers waterproofing system insulated.

Leakage in the structure due to the irregular flow of groundwater in the underground structure penetrates into internal spaces such as underground parking lots and basement through underground walls, which is expensive in terms of maintenance of the building. In this study, various composite waterproofing methods installed on the outer walls of underground structures were selected to evaluate the structural performance of composite specimens due to bending behavior through experiments and analysis on bending test behavior on concrete attachment surfaces.

This study purposed to investigate the optimal outrigger location in tall building with cap truss after a structural schematic design of 80 stories building was performed by using MIDAS-Gen. In this paper, the main parameters of structural analysis were the outrigger location and stiffness of main structural elements (outrigger, exterior column, shear wall etc). In order to search the optimal outrigger position in high-rise building with cap truss, we analysed and examined the lateral displacement of top floor which is one of the very important considering factors of tall building structural design. The paper results indicated that the outrigger location and the stiffness of main structural elements such as outrigger, exterior column and shear wall had an effect on the optimal outrigger location. And it is verified that the study results provided the basic engineering data for fixing the most optimal outrigger location for minimizing the lateral displacement of tall building.
