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.

Now, in a domestic country, the rebuilding and redevelopment of existing houses has been rapidly increasing with an economic growth and the improvement of living condition. As a result of that, a lot of C&D waste has been also produced. Nevertheless, it is not easy to find the research results for appropriate treatment and management of C&D waste in domestic. Therefore this study suggests the optimum deconstruction management system for minimizing construction waste and increasing reuse or recycle rate of material different from traditional demolition. The system makes it possible to plan and manage in advance quantity of C&D waste, demolition methods of each structural elements and application methods of produced C&D waste through an integrated and computerized system. The purpose of the system is ultimately to contribute to minimizing environmental damages and reducing construction waste quantity of a country. This system is largely composed of four modules such as planning of preliminary demolition survey, estimating of demolition quantity, planning of demolition schedule and planning of construction waste management and each module can be also used individually according to the purpose of a user.

The importance of construction waste reusing and recycling is becoming increasingly large because the demolition industry is in current trend to pursue for sustainable growth. As the considering situation of the domestic housing construction and existing house, a scale of demolition industry is expected to be increased continuously. But the related cost regulations that are used in tendering in the demolition industry are insufficient, also the computer system for estimating the demolition costs have not been developed yet. Therefore, in this study suggests man-hours of 21EA items which are utilized to estimate demolition cost and work rate of $1.0m^3$ breaker which is used mostly in domestic demolition industry after analyzing a case study for deconstruction works. The computer system is developed for the estimating demolition cost easily, which are including five modules such as a project information, a unit cost management, a standard unit cost table, a bill of quantity, and a reporting system. This computer system is possible to apply for estimating cost of both mechanical demolition and blasting demolition. The biggest advantage of this system is to estimate cost to utilize standard WBS which is linked with standard unit table and each DB. This can help unskilled users use easily for it.

존 켈리 회장은 7월 12일 경주시 힐튼호텔에서 열린 '원자력 안전 및 해체산업 육성 국제 포럼'에 참석하여 'Perspectives on the Future of Nuclear Power in the United States'를 주제로 특별강연을 했다. 켈리 회장은 강연을 통해 미 행정부의 원자력정책, 미국 원자력산업의 단기 도전 과제, 전력 생산에서의 이산화탄소 감축과 원전 역할, 원전의 지속적인 운영, 미국에서 진행되는 신형 원자로 설계 등을 피력했다. 켈리 회장은 이날 언론과의 인터뷰에서 "한국은 원자력산업 강국인데, 원전 안전성에 대한 과학적인 근거보다 정치적 이슈로 신규 원전을 짓지 않고 수명 연장 대신 조기 폐쇄를 결정한 것은 우려할 사안"이라고 말하고 "원전산업 축소는 장기적으로 기업의 전력 확보가 어려워져 경제적 타격을 입는다. 특히 한국은 원전을 수출하면서 탈원전정책을 펴면 수출에 지장을 받지 않을까 걱정된다."고 밝혔다. 켈리 회장은 MIT 원자력공학박사로 미국 에너지부(DOE) 원자력에너지 기술책임자를 지냈다. 본고는 발표 내용을 정리한 것이다.
