This study is intended to evaluate a risk of overseas construction companies. To achieve this, a survey was empirically carried out to overseas construction site experts. The results were as follows. The relative importance of parent factors showed that‘social culture’(0.157) was the highest, followed by ‘institutional regulation’(0.150),‘environment’(0.145),‘productivity’ (0.142),‘economic finance’(0.137),‘market condition’(0.136) and‘political policy’(0.133). As for the above-mentioned findings, the most important risk factor in overseas construction was social culture of entry countries, followed by construction-related legal system. All construction companies, contractors and design companies said that social culture was the most important parent factor, varying from construction industry. And they said that workforce availability was also the most important in the importance of sub-factors, followed by conflict due to the differences in lifestyle. Consequently, it is important to manage risk for socio-cultural factors in overseas construction, risk for double workforce, and risk for the differences in thinking or lifestyle by the participation of multinational workforce.

Total accident rate in the construction industry is a very meaningful reduction to establish a comprehensive disaster reduction measures, including through the Survey, the disaster prevention projects whilst driving status and problem analysis in order to reduce the mature workers in the construction industry is growing rapidly in all disaster disasters (share) The days. It is urgent to establish a framework and measures that can identify the specific cause for this than for the middle-aged workers and disaster reduction in disaster reduction efforts, which continue to increase. Used as measures of information and data presented in the basic requirements of mature workers also been.

Share of total accidents in construction accidents construction site accident 70% of small embroidery Reducing the rate of Construction of the entire construction accidents decreased overall is a very meaningful work. Disaster reduction continues to increase despite the efforts of a small construction site(Amount less than 2,000,000,000) for Disaster Reduction In order to identify more clearly the cause of the system and provide the urgently needed measures.
