Violation

Machine-translated summary — verify against original

Waterworks Machinery Co., Ltd. violated Article 26 of the Construction Business Act by assigning personnel who did not meet qualification requirements as chief and supervising engineers at construction sites. Additionally, the company submitted false management review results to public project authorities by listing unqualified personnel on the technical staff register and submitting fabricated review results obtained through false applications. These actions are recognized as violations under Article 28, Paragraph 1, Item 2 of the Construction Business Act. The Kanto Regional Development Bureau ordered a suspension of business activities related to public construction projects across Japan and in specific prefectures, from February 25, 2023, to April 10, 2023, for 45 days, and from April 11, 2023, to May 2, 2023, for 22 days.
