Violation

Machine-translated summary — verify against original

In the 2022-2023 construction projects ordered by the Chubu Regional Development Bureau, NIPPO Corporation's affiliated plant supplied asphalt mixture materials to the contractor. Although the contract documents specified the use of new aggregate asphalt mixtures, investigations by the Ministry of Land, Infrastructure, Transport and Tourism revealed that the plant used recycled aggregate asphalt mixtures and falsely labeled the recycled mixture as new asphalt mixture on shipping documents. The company received reports indicating the asphalt supplied might not meet the specified standards but failed to take appropriate measures to prevent this. Similar violations occurred across multiple projects, including the Kita-Tamagaki North and West paving works, Owari East renovation, and Kiso maintenance projects, where the asphalt mixtures supplied contained recycled materials despite contractual requirements for new materials. The company’s close capital and personnel ties with the affiliated plant and its awareness of the issues, coupled with inadequate management responses, led to the suspension of designation by the Chubu Regional Development Bureau from April 11 to August 10, 2025.

中部地方整備局が発注し当該業者が受注し、施工した「令和4年度津国道維持管内舗装修繕工事」において、当該業者の系列プラント会社は、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業者に対し出荷していた。 これらの工事においては、中部地方整備局と当該業者の契約図書(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、系列プラント会社は、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、中部地方整備局発注の「令和4年度23号北玉垣北舗装工事」、「令和4年度23号北玉垣西舗装工事」、「令和5年度尾張東部舗装修繕工事」、「令和2年度19号七笑橋橋梁補修工事」、「令和4年度19号七笑橋補修整備工事」、「令和4年度木曽維持管内維持修繕工事」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。 これらの工事においては、中部地方整備局と当該工事の受注者の契約図書(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、受注者からも系列プラント会社に対し「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。しかし、国土交通省が実施した調査の結果において、系列プラント会社は、「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。
