We evaluate and record the deterioration of bridges, such as concrete spalling, exposed rebar, salt damage, and fatigue, by each component.
The deterioration of bridges progresses due to multiple factors such as cracking, spalling, exposed rebar, salt damage, and alkali-silica reaction. Systematically understanding "which components are deteriorating and to what extent" directly relates to determining repair priorities and planning maintenance. This service combines close visual inspections and sound tests to evaluate the deterioration status of bridges by component. A report will be created that records the types, locations, and degrees of changes, providing a basis for assessing soundness and making repair decisions. It addresses the needs of those responsible who wish to "organize the current state of aging bridges" and "determine the priority of repairs."
