In this study, the vibration data were obtained to analyze the vibration generated during dismantling of slab using the mechanical dismantling method. The obtained vibration data were classified according to the attachment device and then the waveform and dominant frequency analysis were performed. And the correlation was analyzed by the different methods of measuring the distance between the work section and the measurement point. As a result of the waveform analysis for each attachment device, there was little change in the phase of the vibration waveform and only the change in amplitude, which is the magnitude of the vibration velocity. And as a result of frequency analysis, the frequency band was lower when using a crusher method than a braker method and frequency band were close of the natural frequency of the structure to be dismantled. As a result of the correlation analysis, the separation distance was estimated a higher correlation when evaluated as the path through which the vibration propagates along the structure frame than the straight distance between the measurement point and the working section.

Current domestic safety training in building demolition works are heavily relies on the limited number of experienced people and thus, it implies the demand of preparing the systematic program and stricter yardstick is soaring. Questionnaire survey and in-depth interview results with demolition engineers were analyzed adopting AHP methodology. Analysis results reveal that the most urgent items which required improving current safety training system are to increase investment level, prepare more structured training system and secure experts, and so on. In addition, field labors and managers strongly requested the improvement of environment-related safety matters. Based on the evaluation results, guidelines were suggested for the improvement of safety training system in building demolition works.

Recently, the urban centralization phenomenon appears to be growing. As a result, many vigorous efforts for the use of underground space are being made. In particular, the basement depth of construction in the downtown area has deepened and construction is often done close to adjacent buildings. In this case, generally, the underground construction approach mainly used is the composite basement wall system. However, a cost analysis of the basement composite wall system does not exist. Therefore, in this study, the cost of the composite basement wall system was analyzed. The percentage breakdown of costs were: buttress work processes, 3% form work processes, 26% reinforcement work processes, 12% support work processes, 42% and other processes,17%. Accordingly, it will be necessary when developing new technology and construction methods to determine the development focus.

In this study, as a foundational research aimed at promoting the efficient recycling and environmentally friendly disposal of construction waste through the activation of a selective dismantling system, our primary objective was to analyze the economic feasibility of implementing selective dismantling. To achieve this, we conducted an assessment on a 5-story residential building with a construction area of 2,400 m² as a case study. When considering the additional cost of dismantling construction ① the reduction in waste disposal costs due to decreased mixed waste, ② and the potential revenue from recycling through the separation and sorting of waste materials, and ③ we were able to comprehensively confirm that there is an expected cost-saving effect totaling 34,727,000 KRW when compared to conventional demolition methods.

According to statistics from the Ministry of Land, Infrastructure and Transport in 2018, approximately 37% of residential buildings in Korea need to be reconstructed. Due to the rapid growth of the demolition industry, many side effects such as environmental destruction and safety accidents are becoming a problem in the demolition of existing buildings. This study proposes a decision-making process for selecting the most suitable dismantling method for field application by comprehensively considering safety, economic feasibility, and environmental characteristics. In particular, field applicability is evaluated by evaluating risk factors for the selected method. To this end, this study proposes the TOPSIS method for the selection of the dismantling method using the QFD development concept, and the FMEA method as a continuous development process of the selected method.

Korea has a high volume of exhaust in environmental pollutants compared to her economic size, which results from the increase of the ratio in high energy consuming industries. There arises an issue that efficient energy saving is not achieved in the related projects of the construction, which is one of the high energy consuming industries. In addition, such projects of dismantling old and decrepit buildings are frequent in recent years. Given the situation, to obtain much better effects of energy saving, it is necessary to build basic databases and develop utilization plans on energy consumption volume, exhaust volume of pollutants, and environmental expenses that come from the dismantlement stages out of the life cycle of construction projects. Therefore, this study calculates the exhaust volume of environmental pollutants, converts it into environmental expenses by pollutants, and evaluates the environmental economics on the projects of dismantling buildings, utilizing LCI DB that is suggested by Ministry of Knowledge Economy and Ministry of Environment. For this purpose, related data research, the existing literature study, and on-the-spot field investigation were conducted. Based on the results of analysis on the collected data, the environmental economics of the target building was evaluated.

석면은 여러 가지 장점에도 불구하고 석면을 흡입할 경우 폐암, 악성중피종 등과 같은 치명적인 폐질환을 유발한다. 몇 년 전까지 우리의 일상생활 속 건축물의 건축자재, 자동차 부품 등에 특별한 제약 없이 석면이 여러 가지 자재로 사용되어 우리 일상생활에 분포되어 있으며 석면을 안전하게 관리하기 위해 분야별 석면관리제도가 추진중에 있다. 석면해체 제거작업 및 건축물 석면조사의 법 사각지대가 발생하고 있어 제도적 보완이 필요한 시점이라 하겠다.
