Violation
The construction company engaged in misconduct regarding public construction bidding and contract procedures by preparing a work cost breakdown sheet for Nikken Hoken Kogyo Co., Ltd., G-Tech Co., Ltd., and Art Kensou Co., Ltd., submitting it to Osaka City, acting as their bidding agent, and exchanging related information with other companies before the bid. These actions violated Article 4, Item 2, which states that bidders must independently determine their bid prices without consulting other bidders about bidding intentions, prices (including bid guarantee amounts), or related documents, and Article 4, Item 3, which prohibits intentionally disclosing bidding intentions or prices to other bidders before the award decision.
