Violation

Machine-translated summary — verify against original

Nishiyama Komuten Co., Ltd. removed part of the ground improvement structure beneath an existing L-shaped retaining wall without consulting the client during the construction of a U-shaped retaining wall for the Mukae River Road Improvement Project in Toyooka City, Hyogo Prefecture, contracted from the Toyooka River and National Highway Office. They backfilled with soil without verifying the strength, resulting in settlement and tilting of the L-shaped retaining wall. To conceal the settlement and tilt, the company applied mortar over the repaired area, which caused cracks due to displacement, discovered by the client.
