Safety Inspection for Important Architectural Cultural Heritage

By conducting regular inspections of important cultural properties, the risk of damage can be assessed and preventative safety measures implemented; furthermore, in order to establish comprehensive and scientific preservation procedures, research and development of safety monitoring technology for cultural properties and management-manual development are under way.

Measuring a crack

NRICH examines important architectural heritages protected by law on a regular basis, using various measuring devices, and takes measures to prevent damages.

Timeline and Current Status of the Cultural Resource Safety

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.

Safety inspection of cultural properties in provinces and municipalities

Safety inspection of cultural properties requested by cities and provinces

NRICH conducts safety inspections of important cultural properties at the request of the provincial or municipal authorities concerned, and submits the results of its inspection, monitoring or repair work to the authorities in charge.

Since the mid-1990s, NRICH has introduced cutting-edge instruments - such as vibration meters, electro-optical distance measuring instruments, crack measuring gauges, and ultrasonic explorers - to monitor and diagnose the safety of valuable architectural heritages and increase the quality of its safety inspections. The institute is also committed to conducting R&D aimed at improving the functions of the devices and ensuring more scientific and systematic safety management of valuable tangible heritages.
