Violation

Machine-translated summary — verify against original

The operator conducted moisture content tests on fill materials used in the R5 Ken-Ōdō Ōyama District Improvement No. 5 project ordered by the North Capital National Highway Office. During testing, samples with visibly low moisture content and good quality were selectively taken. After the incident, an investigation revealed that some fill was constructed using softer soil with higher moisture content than the samples tested, resulting in a roadbed that did not meet quality standards.

当該業者は、北首都国道事務所発注の「Ｒ５圏央道大生郷地区改良その５工事」において、路体に使用する盛土材の含水比試験を行う際に、見た目で含水比が低く品質の良いところから試料を採取して試験を実施していた。事案発生後、当該業者が実施した原因調査の結果、含水比試験に用いた試料とは異なる含水比の高い軟弱な土により一部の盛土がなされていたことが確認され、その結果、品質を満足しない路体となっていたことが判明した。
