| English summary | 株式会社ＮＩＰＰＯ (NIPPO Co., Ltd.) was subject to a designation suspension by the Kyushu Regional Development Bureau from April 11, 2025, to July 18, 2025, due to violations related to asphalt construction projects ordered by the Tohoku, Kanto, Hokuriku, Chubu, Kinki, and Chugoku Regional Development Bureaus, as well as the Tokyo Aviation Bureau. It was found that the company used asphalt mixtures containing recycled aggregate instead of the specified new aggregate asphalt in these projects. Although the contract documents (special specifications, design drawings, etc.) mandated the use of new aggregate asphalt, the company used recycled aggregate asphalt without prior consultation with the client, and its affiliated plants misrepresented recycled asphalt as new asphalt on shipping documents. The company received management reports indicating the possibility of using recycled asphalt but failed to take appropriate measures to prevent this, thus breaching procurement and material management obligations. The violation was confirmed through investigations conducted by the Ministry of Land, Infrastructure, Transport and Tourism. The suspension period is from April 11, 2025, to July 18, 2025, and was issued by the Kyushu Regional Development Bureau. |
| Original Japanese text | 株式会社ＮＩＰＰＯ（以下「当該業者」という。）は、東北地方整備局・関東地方整備局・北陸地方整備局・中部地方整備局・近畿地方整備局・中国地方整備局、東京航空局発注の工事において、アスファルト工事を施工したが、設計図書で指定したアスファルト合材と異なる再生骨材が混入したアスファルト合材を使用したことが判明した。 これらの工事においては、契約図書（特記仕様書、設計図面等）で「新規骨材によるアスファルト合材（新規アスファルト合材）の使用を指定」されていたものの、当該業者は、国土交通省が実施した調査の結果において、発注者との協議を経ずに「再生骨材を含むアスファルト合材（再生アスファルト合材）を使用」し、かつ、系列プラントは、製造した「再生アスファルト合材」を出荷伝票には「新規アスファルト合材」と明示したうえで、当該業者へ出荷していたことが判明した。 当該業者は、系列プラント会社から管理指標実績等の報告を受け、同社から納入されたアスファルト合材が新規アスファルト合材でなければならないのに再生骨材を含む可能性を認識できたが、系列プラント会社による上記の行為を防止するための適切な対応を怠り、結果回避義務を果たさなかった。 また、当該業者の系列プラント会社は、東北地方整備局・関東地方整備局・北陸地方整備局・中部地方整備局・近畿地方整備局・中国地方整備局発注の工事において、アスファルト舗装工事に使用するアスファルト合材を当該工事の受注者に対し出荷していたが、契約図書（特記仕様書、設計図面等）で「新規骨材によるアスファルト合材（新規アスファルト合材）の使用を指定」されており、受注者からも「新規骨材によるアスファルト合材（新規アスファルト合材）を指定」されていたものの、国土交通省が実施した調査の結果において、「再生骨材を含むアスファルト合材（再生アスファルト合材）を使用」し、かつ、製造した「再生アスファルト合材」を出荷伝票には「新規アスファルト合材」と明示したうえで、当該工事の受注者へ出荷していたことが判明した。 当該業者は、系列プラント会社と密接な資本・人的関係にあり、また、同社から管理指標実績等の報告を受け、同社が出荷したアスファルト合材について、新規アスファルト合材でなければならないのに再生アスファルト合材である可能性を認識できたが、その適正な管理のために必要な行為を取らなかった。 |
