We will respond with reliable inspection techniques in accordance with the Ministry of Land, Infrastructure, Transport and Tourism's inspection guidelines, and with record quality that can be utilized for maintenance management.
Inspection of bridges and tunnels does not yield the same results regardless of who conducts it. Oversights in identifying changes, accuracy of records, and the basis for assessing structural integrity—these qualities vary significantly depending on the knowledge, experience, and recording methods of the inspection technician. Our company conducts systematic close visual inspections and sound tests in accordance with the inspection guidelines set by the Ministry of Land, Infrastructure, Transport and Tourism, and we meticulously document the type, location, and extent of any changes. We prepare reports with clear bases for assessing structural integrity, ensuring they can be reliably used for repair decisions, administrative reporting, and design documentation. Our extensive inspection track record, primarily in Eastern Japan, and our ongoing commitment to improving technology support the quality of our inspections.
