Developing a Framework for Evaluating Project Feasibility of Disaster Management Facilities: Case Studies of Two Protective Shelters in South Korea

초록

In recent years, North Korea has been escalating military threats through nuclear tests and intercontinental ballistic missiles, which is a serious concern worldwide. To deal with these threats, South Korea relies on active protection strategies, such as the 3K system. Although existing defense strategies can yield positive outcomes, it has limitations in ensuring the safety of the people. In response, developed countries such as Sweden, Switzerland, and Finland have prioritized constructing improved protective facilities. To achieve more effective safety and disaster management, it is essential to adopt and improve protection approaches, such as defense shelters, warning systems, and training. However, current shelters such as subways and parking lots exhibit insufficient capabilities against chemical, biological, radiological, and nuclear (CBRN) attacks. Moreover, it is crucial to address the project costs associated with constructing these protective facilities, as significant expenses are incurred. Therefore, the objective of this research is to develop a systematic framework that evaluates the economic feasibility of constructing protective facilities by considering factors such as increase in floor area ratio, operational profits, and increase in household units. As a result, this research confirmed the project feasibility depending on the increase in floor area ratio and operational profit. The research findings are expected to provide valuable insights for evaluating the feasibility of future projects in safeguarding the public against potential threats including CBRN attack. Moreover, the framework is not limited to protective facilities but can be universally applied to a wide range of feasibility evaluations, including safety management and disaster preparedness of buildings in various countries. © 2024 American Society of Civil Engineers.
