| English summary | Nishiyama Construction Co., Ltd. was involved in a road improvement project on the Mukaihiki River in Toyooka City, Hyogo Prefecture, contracted by the Toyooka River National Highway Office. During the construction of a U-shaped retaining wall, the company removed part of the ground improvement under an adjacent L-shaped retaining wall without consulting the client, and backfilled with soil without confirming the strength. This caused the L-shaped wall to settle and tilt. To hide these deformations, the company applied mortar over the repaired area, which resulted in cracks due to displacement, later discovered by the client. The Kinki Regional Development Bureau issued a suspension of designation from November 28, 2025, to January 27, 2026, under the provisions for suspension related to contract violations. |
