Recently, the frequency of heavy rainfall is increasing due to the effects of climate change, and heavy rainfall in urban areas has an unexpected and local characteristic. Floods caused by localized heavy rains in urban areas occur rapidly and frequently, so that life and property damage is also increasing. It is crucial how fast and precise observations can be made on successful flood management in urban areas. Local heavy rainfall is predominant in low-level storms, and the present large-scale radars are vulnerable to low-level rainfall detection and observations. Therefore, it is necessary to introduce a new urban flood forecasting system to minimize urban flood damage by upgrading the urban flood response system and improving observation and forecasting accuracy by quickly observing and predicting the local storm in urban areas. Currently, the WHAP (Water Hazard Information Platform) Project is promoting the goal of securing new concept water disaster response technology by linking high resolution hydrological information with rainfall prediction and urban flood model. In the WHAP Project, local rainfall detection and prediction, urban flood prediction and operation technology are being developed based on high-resolution small radar for observing the local rainfall. This study is expected to provide more accurate and detailed urban flood warning system by enabling high-resolution observation of urban areas.

This research aims to build a total information system that systematizes existing sporadic information, which may lead to revitalization and efficiency of overseas urban development. To achieve this, this study firstly analyses the current information systems for urban development in foreign countries and information from the private sector. The results show that the information system that operates in the domestic agencies, are less likely to involve the contents related to information sharing, social network building and business process. However, that used in agencies ordering the overseas urban development projects, mostly provides the information of professionals, project participants and their business. Second, this research selects the information to be provided by the integrated information system and proposes a data collection plan. The information, required to push forward urban development in abroad, is classified into seven categories. Third, this study establishes a target model of comprehensive information system and makes suggestions for institutional improvement. For doing this, it categorizes overseas urban development information, links to classified information, organizes the system into three stages to services through informational channels, and then suggests a target model. Furthermore, it proposes institutional improvement to achieve efficiency of information systems through a comprehensive review of the similar cases such as administrative system of architecture(Seumter) and land information system.

This study introduces a comprehensive framework for 4D safety analysis in construction site layout planning (CSLP), using a Site Information Model (SIM) environment to enhance spatial hazard identification and effectively integrate it with activity-based safety management. The framework, grounded in a continuous-space layout approach, accurately positions objects to mirror temporary facilities' actual boundaries, incorporating spatial relationships and inherent safety hazards. It also features rasterization to translate layouts into a grid system. Central to this framework are three modules for spatial hazard identification: Visibility Analysis, Spatial Hazard Mapping, and Travel Path Analysis, designed to identify less visible spaces, assess spatial hazards, and simulate optimal travel paths considering safety aspects. By applying this framework to case studies of a residential complex and a commercial office project, the research demonstrates its practical utility in improving visibility and spatial hazard assessment, despite the inherently complex dynamics of construction sites. The study acknowledges challenges, such as the reliance on safety managers' experiential knowledge for setting hazard parameters and the need for further development in integrating these insights with activity-based safety management. It underscores the framework's significant potential to advance construction safety management by offering a method to preemptively recognize and mitigate spatial hazards. The approach promises not only to contribute to accident prevention but also to enhance overall project performance by incorporating spatial and temporal dimensions of safety into CSLP. This research marks a significant step toward a more holistic and integrated approach to construction safety, highlighting the importance of continuous improvement and adaptation in safety practices.

Currently energy use planning council system is mandatory especially for the urban development project planned on a specified scale or more. The goal of existing demand prediction was to calculate the maximum load by multiplying energy load per unit area by building size. The result of this method may be exaggerated and has a limit in the information of period load. The paper suggests a new forecasting process based on standard unit household in order to upgrade the limit in demand prediction method of multi-family housing complex. The new process was verified by comparing actual using amount of multi-family housing complex to forecasting value of energy use plan.

The construction of bored tunnels in soft ground inevitably causes ground movements. In the urban environment these may be of particular significance, because of their influence on buildings, other tunnels and services. The prediction of ground movements and the assessment of the potential effects on the structures is therefore an essential aspect of planning, design and construction of a tunnelling project in the urban environment. In this study, to minimize the effect of tunnelling-Induced ground movements on the adjacent structures, a system for tile settlement risk management was developed. The GIS based risk assessment system for adjacent structures developed in this study consists of several modules such as building information module, settlement evaluation module, potential risk assessment module for adjacent structures, and analysis module for monitoring data. This system focuses on controlling and managing construction processes that may lead to settlement In the surrounding buildings and can contribute to producing the optimum technical and economic design.

This is on-going project planned from June to August, 2003 for the development of sub-urban housing of 108 buildings on 30,000 pyung lot located in Dochuk-myun, Kwangju-si, Kyunggi-do. The Site is consist of 10 different building sizes ranging from 45pyung to 65pyung on 180 to 220pyung lot. Buyers can customize their types and functions based on given sizes. Most sub-urban housing until now was based on typical planning and had no regard for its characteristics of diverse location. To solve these problems, I designed each types according to its locational characteristics and gave each lot flexible shape to have identities. To take advantage of its undulation, I put playground and sports facilities like swimming pool and tennis court at the approach. Central square to the center and park and observatory to the top
