  • 본 연구에서는 EN 13823 기준을 적용한 시험방법인 SBI(Single Burning Item)을 이용하여 스티로폼 샌드위치패널의 화재특성에 대한 실험을 실시하였다. 현재 국내에서는 샌드위치패널 화재특성 평가방법으로 ISO 5660-1(콘칼로리미터 시험방법)과 KS F 2271(난연성시험)이 사용되고 있지만 이러한 시험방법들은 시험 스케일과 시험편 및 가열조건의 한계점 등을 보이고 있다. 따라서 본 연구에서는 1세트를 3개로 하여 총 9개의 75mm 두께인 스티로폼 샌드위치 패널을 이용한 실험을 실시하였다. 이를 통해 공학적인 화재 물성 값인 FIGRA(FIre Growth RAte, kW/s), SMOGRA(SMOke Growth RAte, m2/s2)등을 측정하였다.

  • Recently, in Korea, various technology developments have been made to utilize 3D space and facility data such as unmanned aerial vehicles (UAV) and laser scanners with the goal of improving productivity at construction sites. However, the lack of related regulations for 3D laser scanner surveying has been a barrier to using the technology across the surveying industry. As a result, owners, contractors, and construction supervisors are reluctant to introduce and apply technology to the site. In this study, the guidelines (drafting and inspection work to be supervised by construction supervisors when constructing earthworks using laser scanners) was developed and presented so that the earth surveying and quantity calculation technology using a laser scanner could be applied and diffused in a construction site. Through the development of this guideline (proposal), it is judged that the supervision and inspection of earthworks quantity using a laser scanner will be activated in the field.

  • This paper deals with technology relevance analysis, which measures technological dependency between needs technology and its component technology as well as between needs technologies. The two-round survey was carried out: In the first round, a wide range of needs technologies in construction and building industry were identified and classified to meet a variety of social needs which were anticipated in the near future of Korea. In the second, relevance between needs technology and its component technologies was checked by some 120 experts. Based on the survey results, the individual relevances among needs technologies were computed. Finally the ranking of needs technologies in construction industry was set according to the degree of technology relevance. This relevance is to be used as one of criteria for the selection of national R&D projects which the Ministry of Construction and Transportation plans to promote in the next five years.

  • One of the main issues of government is the development of local areas which have been neglected while major capital was invested on Seoul and its satellite cities. Korean Ministry of Construction and Highway and other government departments are currently working together (or the balanced development of the local areas. Localization which is the balanced development of the Capital and local areas, can be achieved through the balanced development of local industry and technology. It is required to have a strategic approach to the construction technology improvement that is localized and eventually contributes the localization efforts. Construction technology that is associated with the local characteristics is the key factor of the balanced national development. This study includes defining the 'localization' through the investigation of national and international localization examples. Construction technology that reflects the local characteristics is studied in this paper. Local characteristics are identified by (1) surveying 'construction technology demand'; (2) measuring construction technology capability, and (3) studying on government regulation changes. 1'he results provide the fundamental Information for the development of the local construction technology.

  • In evaluating the competitiveness of construction companies and their development strategies, patents are a useful and objective source of technical information. In this study, the cutting-edge technologies of construction industries of China, Japan, and South Korea were investigated based on the data of patent applications filed by a total of 15 construction companies (five companies from each country). The related technologies were classified into six core technology groups based on their keywords. After that, we used four patent analysis methods: time series analysis, IP (Intellectual Property) emergence level analysis, spiral module analysis, and OS (Object-Solution) Matrix analysis, to identify the promising technologies/vacant technologies for global construction companies in China, Japan, and South Korea, and to analyze the technical competitiveness of the three countries. The findings of this study showed that each country can claim a relative technological advantage over the others. Overall, 3D printing and offsite construction technology, data acquisition technology, AR and VR technology are expected to be promising in the Asian region. The present study contributes to the body of knowledge by expanding our understanding of technological innovation for the competitiveness of companies and the technology development strategies pursued by the construction industries of China, Japan, and South Korea.
