Inspection Initiative Regularly-scheduled inspections of important cultural heritage began in 1981, with the preliminary inspection of 11 stone structures, such as the Five-story Stone Pagoda at Jeongnimsa Temple Site, Buyeo. The focus remained on stone structures until 1994 (11th annual inspection), which included tests to measure their vertical and horizontal inclinations. In 1995 (12th annual inspection), eight wooden buildings were added to the list of cultural properties inspected, which has steadily expanded since then to include a greater variety. Since 1997, depending on the condition of some seventeen cultural properties, including ten important stone cultural properties and seven important wooden structural cultural properties, safety inspections have been conducted with increasing frequency (i.e., every one, two or four years) and the methods of assessment diversified and improved.

Since the mid-1990s, scientific and high-tech instruments such as oscillometers and geodimeters, devices for measuring cracks, and ultrasonic exploratory equipment have been used during safety inspections to enhance precision, while research and development of various instruments has been prioritized.
