Violation

Daisho Doken (法人番号6120001066659), located at Osaka City, Kita-ku, Honjo Higashi 2-10-15, was subject to a three-month bidding participation suspension from December 1, 2021, to February 28, 2022, by Osaka Prefecture. The suspension was based on violations of the Construction Business Act Article 28, Paragraph 3. The violation involved the procurement process for public works ordered by Osaka City, where an administrative scrivener (not the registered cardholder) was requested by multiple construction companies, including Marushin Co., Ltd., Gakuken Kogyo Co., Ltd., Sugigumi Co., Ltd., and others, to hold their IC cards. This individual submitted bids on their behalf, including preparing cost breakdowns and system input for electronic bidding, actions that undermined bidding fairness and were deemed inappropriate for qualified persons. The companies involved include those with licenses from the Minister of Land, Infrastructure, Transport and Tourism, such as Gōken Co., Ltd., Yamada Co., Ltd., Amimoto Komuten Co., Ltd., and Kōsei Kensetsu Co., Ltd. The company was also issued a business suspension order from February 21 to March 14, 2022, for all construction-related operations, based on the same violations.
