Violation

Kabushiki Kaisha Seiko Kogyo violated Article 3, Paragraph 1 of the Construction Business Act by undertaking multiple construction projects exceeding the amount specified in Enforcement Order Article 1-2 without the necessary permits. This constitutes a violation of Article 28, Paragraph 2, Item 2 of the same Act. Additionally, during construction from November 2022 to March 2023, the company assigned personnel who did not meet qualification requirements as chief engineers. This violates Article 26, Paragraph 1, and Article 28, Paragraph 1, of the Construction Business Act. The Saitama Prefecture has issued an instruction based on these violations, requiring the company to implement measures to prevent recurrence, including internal awareness, compliance with laws, and ongoing training.
