Violation

Machine-translated summary — verify against original

Iwamoto Kenzai-ten Co., Ltd. was subject to a three-month business suspension by Osaka Prefecture from December 1, 2021, to February 28, 2022, based on Article 28, Paragraph 3 of the Construction Business Act. The violation involved the company entrusting its IC card to an administrative scrivener (the same individual as the bidding officer at Daisou Doken Co., Ltd.) who was not the cardholder, and submitting bids through electronic system input, including the preparation of cost breakdown sheets, during public construction bidding by Osaka City. This act was deemed to undermine the fairness of the bidding process and was considered inappropriate for a qualified contractor.
