Violation

Machine-translated summary — verify against original

In a general competitive bidding process for public works contracts ordered by Osaka City, multiple construction companies and related entities had their IC cards used for bidding by an administrative scrivener who was not the cardholder but was the same person as the bidding officer of the construction companies. The scrivener was entrusted by these companies to hold their IC cards and submit bids through system input for electronic bidding, including preparing the cost breakdown sheets. The act of a bidding officer of a construction company holding another entity's IC card was deemed to undermine the fairness of the bidding process and was inappropriate for a qualified person. As a result, Osaka City imposed a three-month bid participation suspension on the construction companies from December 1, 2021, to the end of February 2022, pursuant to Appendix 14 of the Osaka City Bid Participation Suspension Guidelines.
