Violation

Machine-translated summary — verify against original

The company’s representative director was convicted of a fine for assault on March 31, 2018, which disqualified him under the Construction Business Act. Despite this, he concealed the fact and submitted a false pledge stating he had no disqualifying factors in the construction permit application dated February 12, 2020. Additionally, a director of the company was convicted of violating the Stimulant Control Law and received a probationary prison sentence on June 16, 2018, which he also concealed when submitting a false application. The company subsequently obtained a construction permit on March 10, 2020. These actions constitute violations under Article 29, Paragraph 1, Item 7 of the Construction Business Act.
