Violation
The construction company engaged in misconduct related to public construction bidding and contract procedures. Specifically, during a general competitive bid for construction work ordered by Osaka Prefecture in Osaka City, the company applied for bidding from the same IP address along with Okamoto Kensetsu Kogyo Co., Ltd. and Yutaka Co., Ltd. Subsequently, the company and Yutaka Co., Ltd. bid from the same IP address, and the bid documents for four companies, including Okamoto Kensetsu Kogyo Co., Ltd. and Renuve Daito Co., Ltd., contained identical direct construction costs listed in the cost breakdown sheets. This violated Article 3, Paragraph 3 of the Osaka Prefecture Electronic Construction Bidding Guidelines, which prohibits bidders from disclosing bid prices or details of the cost breakdown before the winner is decided. These actions constituted misconduct in the bidding and contracting process for public works.
