Legal analysis: The public bidding period is generally three days. It is necessary to clarify the difference between the publicity of the winning candidate and the publicity of the winning result. Generally speaking, the tenderee shall submit a written report on the bidding situation to the relevant administrative supervision departments within 15 days from the date of determining the winning bidder for the project that must be tendered according to law. The tenderer shall publicize the successful candidate within three days from the date of receiving the bid evaluation report, and the publicity period shall not be less than three days. Bidders or other interested parties who have objections to the bid evaluation results of projects that must be subject to tender according to law shall raise them within the publicity period of the successful candidate. The tenderer shall give a reply within three days from the date of receiving the objection, and shall suspend the bidding activities before the reply. As the information of the candidate winning the bid has been fully publicized in the publicity link of the above-mentioned candidate winning the bid, and the rights of bidders or other interested parties have been guaranteed, the publicity nature of the winning bid result is only informative publicity, and the winning bid result is only announced to the public, so there is no time limit for this.
Legal basis: Article 45 of the Bidding Law of People's Republic of China (PRC) * * * After the winning bidder is determined, the tenderer shall issue a letter of acceptance to the winning bidder and notify all bidders who have not won the bid. The bid-winning notice has legal effect on the tenderer and the winning bidder. After the bid-winning notice is issued, if the tenderer changes the bid-winning result or the winning bidder abandons the bid-winning project, it shall bear legal responsibility according to law.
