According to documents submitted by Shikoku Butai Television Lighting to the prefecture, it was found that the company had assigned a dedicated technical manager as the chief technician at its office, as required by Article 26, paragraph 3, of the Construction Business Act and Enforcement Order Article 27, for electrical works ordered by Kochi City and mechanical installation works ordered by Yamagata Prefecture. This constitutes a violation of Article 26, paragraph 3, of the Act and falls under Article 28, paragraph 1, item 2, of the same law. The company was issued an instruction based on Article 28, paragraph 1, of the Construction Business Act, requiring measures to prevent recurrence, including proper assignment of technical personnel and internal training. The violation was due to the improper placement of a dedicated technical manager at the office, which is mandated for certain construction works, and the company was instructed to improve its compliance and management systems accordingly.
