The time process of tendering and bidding can be divided into several key stages. According to the "Tendering and Bidding Law", each step has clear time limits. First, the tenderer needs at least 10 days to issue bidding documents or pre-qualification documents, and ensure at least a 5-day sale period. Then, bidders have at least 20 days to prepare and submit bid documents. Bid opening and bid evaluation are usually completed within 30 days after the bid deadline.
The bid evaluation committee shall submit a bid evaluation report and recommend the winning bidder within 10 days after the bid opening. The publicity period shall be no less than 3 days, and the tenderer shall determine the winning bidder within 10 days after the end of the publicity period. The notice of winning the bid is usually issued to the winning bidder and the unsuccessful bidder after the winning bidder is determined. The tenderer also needs to submit a bidding status report to the relevant administrative supervision department within 15 days. Finally, the tenderer and the winning bidder need to sign a written contract within 30 days and return the deposit within 5 days after the contract is signed.
The entire process includes the preparation of bidding documents, determination of the minimum bid, bidding, bid evaluation, publicity, contract signing and other links, ensuring fairness, impartiality and openness.
