Violation

Nishikai Metal Co., Ltd. was subject to a 15-day business suspension from February 21 to March 7, 2022, by Osaka Prefecture under Article 28, Paragraph 3 of the Construction Business Act. The suspension was due to the company's involvement in a bidding process for public works ordered by Osaka City, where an administrative scrivener (the same individual as the bid officer at Daisatsu Doken Co., Ltd.) who was not the registered IC card holder of the company was entrusted with the company's IC card. The IC card was used to submit bids electronically, including the preparation of the cost breakdown sheet. Such actions, involving entrusting the IC card to an unqualified individual, were deemed to undermine the fairness of the bidding process and were inappropriate for a qualified entity. As a result, the company was also temporarily barred from bidding for three months from December 1, 2021, to February 2022, in accordance with the Osaka City bidding suspension guidelines (Appendix 14). The misconduct was the cause of the suspension, which involved the misuse of the IC card and the associated actions that compromised the integrity of the bidding process.

Cause of action

当該建設業者は、大阪市の発注する公共工事の請負契約に係る一般競争入札において、当該建設業者のICカードの名義人ではない行政書士（株式会社大松土建の入札担当者と同一人物）の依頼により当該建設業者のICカードを同人に預け、当該建設業者の入札について、工事費内訳書の作成と併せて電子入札に係るシステム入力による入札書の提出が行われていた。株式会社大松土建の入札担当者と同一人物にICカードを預けるなどの行為は、入札の公正を害し、有資格者としてふさわしくない行為であったとして、このことにより、当該建設業者は、同市より、令和３年12月１日から翌年２月末日までの３か月の入札参加停止措置（大阪市入札参加停止措置要綱別表１４に該当）を受けた。
