  • The purpose of this study is to analyze the efficiency of the noise reduction measure in the downtown construction. For decades, the life level rise in Korea makes the environmental issues developed the important issues. Specially the noise problems have become the hot issue in the building construction. This study covers the efficiency of the measures, which is used in the construction field to reduce the noise. The case was obtained by Korean E&C company in 2003. It is used as important sources. The results of this study are as follows; the reduction efficiency is higher than that of the old measure. But more efforts are needed to comfort nearby residents.

  • Underground structure construction in the downtown is very difficult despite the development of construction technology. We have been a lot of research in order to solve the problem, it was a remarkable achievement. But there are still many difficulties. This study is to analyze the construction technology to demolish the existing underground structures and to build new building applied topdown method at the same time. This technology was effective to suppress interference between the exsisting structure and new building. Therefore, this technology is expected to be able to be used in similar cases in the future.

  • The size of the construction projects become huge and complex, and the depth of excavation for the underground structures become deeper. Also the working area is not enough for loading materials and temporary facilities. This is the most case of recent construction projects in downtown area. Top-down is the most useful method for this kind of construction projects. Top-down construction method consists of supporting method, retaining wall type, foundation type and construction direction such as up-down or up-up. construction managers have to select sub-elements for top-down construction method in planning phase. This study is to suggest the sub-elements selection model for the top-down construction method, and the case study is conducted for evaluating this model.

  • The contiguous construction in downtown area requires an appropriate substructure construction method since it results in the insufficient working spaces and frequent public resentment by noise and vibration. In particular, Top-down method usually is applied for downtown construction, and followed by several difficulties in casting the slab concrete for substructure. In this study, we focus on the improvement workability for substructure construction.

  • Recently buildings are being constructed on the downtown area. In most building construction sites on the downtown area, the need for adequate material inventories are critical in order to avoid project delays and cost increases due to inappropriate deliveries of key materials. However immoderate material inventories cause increasing inventory cost. Therefore, we need a proper management material inventories. This research re-establishes the existing safety stock and analyzes relationship between safety stock and service level. It suggests an economical re-order point based on safety stock considering service level, various demand and delivery time.

  • The HIBRAND located in Yangjaedong, Seochogu, Seoul is a large complex shopping center of total space 48,000 p'yongs which consists of a nineteen-story business facility and a six-story sale facility. In the case of a big construction work in the downtown, they are suffered much difficulty by construction period and working space lack. They, however, can satisfy construction period, constructability and quality using a PC system in HIBRAND. Also, we maximized the advantage of each material being the abreast of a RC and steel structure method partially and devised a reasonable copula. A PC system with advantages of construction period, constructability and quality assurance should be actively practiced to big downtown construction work.

  • Massive underground excavation can be carried out recently due to the technical development of the excavation for retaining wall. Feed-back analysis using field measurement results is recommended to secure the stability of the construction because calculated values at stages of the design and the construction are uncertain. Reinforcement plan should be established based on the result of it. This study deals with the underground excavation site, which is under construction and is close to structure(subway) at downtown area. The result of feed-back analysis on the measurement data of displacement at multi-soil layers was reflected to make a plan for safe construction. This case study can be useful information for contingency plan on abnormal displacement which can be occurred at similar underground excavation.

  • According to the construction environmental changes due to the trend of large scale and complicated building construction, many construction methods(such as : TOPDOWN )are more often used. However, it is pointed out that occupational pulmonary diseases, reduction of the machinery lifetime and productivity caused to be narrow visual field and collision between the workers. Therefore, this study is mainly dealing with the views of productivity and safety improvement in order to improve work efficiency and to insure the safety in underground construction environment.

  • Urban space structure in South Korea when through drastic changes ever since public housing policies began their full-fledge implementation. That is, public housing policies represent the main cause for formation of the current urban space structure, as the public houses are constructed in accordance with changes of demographic/social structure, considering changes of housing demand, in urban spaces demanded by the end users. After rapid industrialization and urbanization in the 1960's, each government in different periods have implemented housing supply policies through massive urban developments, to resolve the issue of housing shortage and residential instability. Phase 1 New Towns were developed in the 1980's resulting in suburbanization of the Seoul Area, followed by urban sprawl due to construction of small-size New Towns after deregulation in the 1990's, and construction of Phase 2 New Towns for resolution of housing shortage in the early 2000's and the resulting urban problems. In the mid-2000's, construction of Bogeumjari houses in GB areas led to insufficient housing supply in downtown areas, and the period after 2010 witnessed continuous deterioration of existing urban areas and acceleration of the rental housing crisis caused by rental housing shortage in downtown areas. Moreover, the residentially vulnerable classes consisting of young, 1~2-member households is expanding, with the real estate market in recess. Therefore, the government is trying to achieve urban regeneration through public housing policies so as to resolve the urban space problem and the housing problem at the same time, and the Happiness Housing Project has been implemented as a policy to achieve that goal. The Happiness Housing Project for young, residentially vulnerable classes in downtown areas, is going through diversification aimed at conjunction with urban regeneration projects in downtown areas, as exemplified by conversion of rental houses in residential environment improvement project districts and redevelopment/reconstruction project districts into happiness housing, and supply of happiness housing in conjunction with small reorganization projects for deteriorated residential areas in such areas as those excluded from New Town designation. Continuous supply of Happiness Housing in conjunction with urban regeneration requires mixed-use residential development which includes convenience facilities and public facilities, along with improvement of rental conditions (rental period/rent) and diversification of project methods, considering that the project is implemented in downtown areas.
