Neglected buildings for long period can seriously reduce the durability of the building due to rust in rebars and deterioration in concrete quality due to exposure to outside air, and the seriousness of suspended buildings such as safety accidents and social crimes is emerging due to poor management. In this study, various problems such as the occurrence of safety accidents were analyzed through a fact-finding survey of buildings that have not been maintained due to long-term neglect in all areas of Jeju. In order to reuse a building that has been discontinued, the safety of the building structure itself must be checked. After securing safety through durability investigation, construction should be resumed or converted into a normal building through re-purposing, dismantling, remodeling, etc.

Buildings that have been long neglected can suffer severe durability reduction due to factors such as rebar rust and concrete quality deterioration resulting from exposure to outside air. Furthermore, the issues associated with these suspended buildings, including safety accidents, social crimes, and environmental pollution, are becoming increasingly serious. This study investigates the current status of these buildings in the Jeju area, identifies the problems, and examines the durability of the structure in a specific location to assess the possibility of future use. Aesthetic surveys(visual and slope inspections) as well as non-destructive tests(compressive strength tests, neutralization tests, and rebar detection tests) were conducted to assess durability. The analysis revealed that the structure maintained satisfactory durability and the building's condition was good in comparison to the years of neglect.
