Violation

Between April 7, 2017, and October 15, 2017, Meiwa Engineering Co., Ltd. violated Article 26, Paragraph 3 of the Construction Business Act by assigning a dedicated technical manager as a site supervisor without proper authorization. Additionally, from April 2017 to December 2019, the company violated the same article by having site supervisors concurrently serve multiple construction projects, despite being required to assign dedicated personnel for each project. These actions constitute a violation of Article 28, Paragraph 1 of the Act. The Tokyo Metropolitan Government issued an instruction on December 8, 2022, requiring the company to promptly inform its staff of the violations, strengthen safety management systems, comply with relevant laws, and develop ongoing safety education plans. The company is also required to report the measures taken by January 13, 2023.
