Recent increasing of redevelopment project causes construction of new buildings after demolition of old buildings. However, the researches have been largely confirmed to analysis of behaviour characteristics of existing subway tunnel due to adjacent excavation which constructing new building so far. Accordingly, The ${\bigcirc}{\bigcirc}$ Building which will be built after demolishing existing parking lot is selected as a subject of study. And the purpose of this study is to analyze the effects on existing subway tunnel due to loading and unloading caused by demolition of upper buildings. The numerical analysis was performed by using the MIDAS/GTS program. Two cases for the numerical analysis were analyzed. The one is considering demolition of old buildings and the other is not considering it. This study is to analyze the effect on existing subway tunnel caused by demolition of upper building by analyzing numerical analysis results for tunnel displacement and lining stress. It was analyzed that the effects of considering the demolition of old buildings are larger than those of no considering it.

With the increased demand on housing quality and effective urban redevelopment, a new paradigm in reconstruction project is in need. Especially, the Urban and Residential Environment Improvement Law which initiated on July 1, 2003 has become a significant turning point. This code is expected to function as a consistent and systematic measure. This study will examine the code's major concepts and methods to progress reconstruction projects effectively. The application of construction management is examined carefully since the new code requires renewal project consulting firms to function as a professional complement rather than simply perform administration work, as in the past. Also, construction managing methods that can be related to renewal project consulting are examined and speculated. Lastly, methods to improve efficiency in reconstruction projects are introduced through case study and analysis on applicability and expected results.

Recently, a research of the urban regeneration has been performed very actively. This is one of the efforts to resolve various social and economic problems coming from the existing deteriorated building and facilities by new urban development or redevelopment. However, an urban regeneration has a characteristic to be unable to ensure the project performance due to the exposed numerous risks coming from the various and complex stake-holders, and its mega sizes. This paper proposes the method of risk performance index in order to improve an efficiency of performance measurement expanding to the risk view point from the existing integrated cost/schedule performance measurement. A risk performance index is compatible with the existing EVMS, and can make the performance measurement in 3 dimensions of the integrated cost/schedule/risk with 18 sub-indexes and variables.

This New-Town Project has been proposed to improve the environments of deprived residential areas. This paper investigates the distribution levels of the participating parties' monetary surpluses from New-Town Projects through a case study and tentatively suggests political issues and measures. The methodology followed includes a thorough survey of the precedent theories, including a literature review concerning issues and tasks that have been raised since the development was initiated. A general assessment of the complete project is also provided with a broad perspective of the background settings. Secondly, the case study of Gil-Eum will be the focus for identifying the mechanism for the project's profit distribution levels, then for constructing a set of measuring procedures according to the stages of the project and the participating parties. This set of procedures that has been drawn out from recognizing the system, is applied to the target project and measures the amount of profit gained from each stage of the development. This also aids in collating information about the procedural arguments concerning the financial gains of the operations that have been provided. This project falls under the 'Urban and Residential Environment Improvement Act', and based on the results of each stage, the measurement of the profits of the participating parties is analyzed.

In this country, now redevelopment and rebuild is becoming largely because it is improving welfare and life condition with high growth of economy. Also, the scale of construction project is trend to increase to adjust the changing social situation. Accordingly, C&D waste is rising largely because of the increased demolition works in city. The right management of C&D waste is becoming one of very important things, but little research has been conducted to estimate correctly C&D waste. This study suggests standard units of C&D waste which can estimate demolition quantity of apartment. These units can estimate easily and correctly C&D waste in demolition works and also can make it possible to use very important material to carry out policy of national waste management.

As with cities, all components of a campus must be carefully calibrated to provide the facilities, services like energy, water, electricity, information and communication; classrooms, libraries and laboratories for working; transportation networks and systems for movement of persons, goods, and services; athletic and other facilities for health and competition; places to eat, recreate and socialize; places to display and store works of arts; spaces for the performing arts' spaces for active assembly or solitary pondering. The goal of this study is how to observe the campus planning and development as a part in the context of the community. This study was taken into account neighborhood concerns and Harvard design guidelines. As an observer for the university's northern campus edge, this study suggests in the context of a long and sometimes turbulent history of dialogue and negotiations between Harvard University and first host community, Agassiz which is one of Cambridge's thirteen neighborhoods.

This paper is about the bow structure design of the ship-typed and turret moored FPSO which is subjected to the bow-flare slamming load in harsh North Sea environments. Quad 204 FPSO project involves the redevelopment of the existing Schiehallion FPSO which is damaged by impact wave loads. Normally all offshore systems including FPSO are designed to withstand the 100 year storm I.e. the storm that happens once every hundred years at the location where the system is installed. Several incidents have revealed that impact loading is important issue for moored floating production systems. In this paper, the design impact loads are estimated considering the ship owner’s specification, measured data from model tests, requirements of the classification society rules and results of numerical simulation analyses. The impact pressure by numerical analysis is 1.8 times greater than required value by CSR adopted by IACS. Based on the selected design load, plastic design formulae allowing the local material yielding are applied for the initial scantling of the bow structure. To verify the structural integrity, FE analyses are carried out considering the local area subjected to the impact wave loads. Their results such as structural arrangement, design loads and scantlings are shown and discussed. It is found that plastic design formulae in adopting Initial design phase give sufficiently conservative results in terms of structural strength.

The important goal of urban renewal is not to reform only Physical environment but to improve people' life quality. people who have been lived in urban renewal area are grouped to owner and tenant. owner of land or house has substituent right but tenant has only house-moving money or rental house by urban renewal. But rental house condition is not good to tenant because tenant has large family, low-income and low grade and it is essential to provide rental house for low-income class and it is worth to analyze tenant house problem The purpose of this study is to analyze the problems of public rental house and to presents solutions. The study was done in following process. First, the literatures on this subject were investigated to seek the problems of public rental house. Second, Survey were done on the staff, who works in the cooperative housing redevelopment and whose jobs are officer, consultant, real estate introducer and designer, to seek problems and solution of public rntal house. survey which is made by three group. one group is made by people who already lived in tenant APT, second group is made by people who are waiting for moving in tenant APT. Third group is made by specialist who has many experience-more than 3years- to urban renewal. Third, the Correlation Analysis was used to analyze the relation between the Area and dwelling satisfaction. Fourth, tenant policy' altenative is presented to solve tenant APT' problem which is analyzed by this study The results are as follows : First, tenant APT' size Which is regulated to 30-$45m^{2}$ is enlarged to more than $45m^{2}$ because tenant family is made up averagely of 4.8 persons. Second, tenant APT' rental cost is reduced to 100 thousand won. Third tenant APT' arrangement is divided from owner because tenant and owner want to live in group by group. Fourth, tenant house type is changed to various house type because tenant is not familiar with APT

Leading Lights and Sector Lights provide a navigable channel, heading reference and a visual indication. Mariners can take easily a reference bearing or line of position. The Busan North Port needed to install a sector light to resolve blind sections because of Busan Port Redevelopment Project D-1 Block Construction Plan. And also the busan new port needed to install a sector light to give safety indication because navigation conditions will be changed due to removal of the to-island. For this reason, design development was made for installation of sector lights. In addition, the results of design development were compared with the AtoN simulation and verified. This paper is expected to be very useful for installing Sector Lights to guide the vessel to port safely in Korea.

As the local economy has become stagnant, various policies have been made to revitalize the enormous construction industry. However, it is difficult for these policies to achieve their objective, as the construction industry is not an island unto itself but is interconnected in complex ways with diverse other areas of the economy. Interviews and surveys were conducted with experts in Busan, in order to identify the causes of the stagnant economy in the local construction market. The main findings were as follows. First, cost reduction and realistic master plans are needed as a solution for the problems of the redevelopment housing plan. Second, the alleviation of the construction policy is also necessary in order to overcome the problems of not considering the local construction industry. Finally, vocational training and quality education are needed to address the low awareness of construction feasibility analysis and the lack of highly trained human resources. The results of the study will help efforts to revitalize the local construction industry, and will provide an opportunity to reconsider the differences between the experts on issues of the industry.
