We are developing a non-destructive testing device that allows even municipal officials and consultant engineers, who are not experts, to easily and quantitatively evaluate the deterioration status of concrete structures, and we are developing human resources using this device. Based on the results of applying various types of non-destructive tests to actual bridges, we are developing easier-to-use equipment and conducting activities to convey the principles and applicability of non-destructive tests in an easy-to-understand manner through trial seminars and other events.
