Violation

Ishikawa Kogyo Co., Ltd., with permit number Osaka-fu Governor (Han-2) No. 21619, was instructed by Osaka Prefecture on September 1, 2022, under Article 28, Paragraph 1, Item 1 of the Construction Business Act. The company was found to have neglected to implement necessary safety measures, such as establishing work plans for the placement of multipurpose earth drills and transportation of materials, and adhering to the maximum load limits of pile drivers. This negligence led to the overturning of a pile driver, which caught on power lines, causing a utility pole to fall, damaging nearby structures, cutting power lines, and resulting in a blackout affecting up to approximately 720 households. The incident posed hazards to the public and was deemed a failure to properly execute construction work. The directive requires the company to comply strictly with the Construction Business Act and related laws, and to take measures to prevent similar incidents in the future.
