The securing of alternative energy is essential, since the Republic of Korea (hereafter, ROK) depends on 97% of its supply from overseas. Since G20 Summit Conference of 2011, it became possible to receive natural gas from Russia for 30 years starting from 2015 with mutual cooperative agreement for the procurement of natural gas/oil and minerals. It enabled Korea to advance to pioneering regions of extreme climate. However, it lacks the experience of design and construction of pipeline projects in permafrost area until now as well as the technique for the management of enormous information, which is generated from the project. This study aims to develop engineering data breakdown structure (DBS) and information flow of pipeline projects in permafrost area. The ultimate goal of this research is to develop a hierarchical structure of engineering/construction data for efficient project management in the extreme climate region. In order to achieve the research purpose, domestic and overseas literatures on this research topic are reviewed, and the business process of the design stage of pipeline projects in permafrost area as well as the characteristics of the important items are analyzed. Additionally, the result of this study will be used to build the comprehensive information management system for the entire process.
