1. In general, the deadline from the announcement to the bidder's registration, pre-qualification and sale of the bidding documents should allow the bidder reasonable preparation time. Although there is no hard and fast rule after verification of this link, the reasonable time in actual operation should be no less than 7 working days, otherwise it is suspected of black-box operation.
2. From the deadline of bidding documents to the deadline of bidding shall not be less than 20 days. When the bid is closed, that is, when the bid is opened.
3. The time from the bid opening of small and medium-sized projects to the end of the bid evaluation by the bid evaluation committee. When the bid evaluation report is submitted and the successful candidate is recommended, the project can usually end on the same day, but the bid evaluation and calibration should be completed at least 30 working days before the end of the bid validity period, and the winning bidder should be determined.
4, 15 from the date of determining the winning bidder, submit a written report on the bidding situation to the competent construction department where the project is located. If the competent department fails to inform the tenderer of the illegal acts in the bidding process within 5 days from the date of receiving the report, the tenderer may issue a letter of acceptance to the winning bidder. The publicity time ends here.
Within 30 days after the bid-winning notice is issued, both parties shall conclude a written contract.
6. Within 7 days after the conclusion of the contract, it shall be reported to the competent department for the record.
7. The bid bond of the unsuccessful bidder shall be returned within 5 working days after the conclusion of the contract, but the winning bidder shall submit the performance bond and return the bid bond of the winning bidder.
The extended data 1, the bidding law and its implementing regulations do not specify the time for issuing the bid-winning notice.
However, Article 56 of the Measures for Bidding and Tendering of Construction Projects, Order No.30 of seven ministries and commissions, stipulates: "After the bid evaluation committee submits a written bid evaluation report, the tenderer shall generally determine the winning bidder within 15 days, but at the latest within the validity period of the bid."
Article 62 stipulates: "The tenderer and the winning bidder shall conclude a written contract in accordance with the tender documents and the bidding documents of the winning bidder within 30 days from the date of issuance of the bid-winning notice." As can be seen from these two provisions:
(1) When the tender documents stipulate that the bid validity period is consistent with the bid bond validity period, the bid opening, bid evaluation, bid selection, bid-winning notice and contract signing shall be completed within the bid bond validity period. The time for determining the winning bidder or issuing the bid-winning notice should be at least 30 working days before the end date of bid validity, so as to have time to sign the contract. Otherwise, the validity of the bid bond will easily expire. Once it expires, if the winning bidder does not sign a contract with the tenderer, the tenderer will have no way to bind the winning bidder because the bid bond has expired;
(2) If the validity period of bid bond is 30 days longer than that of bid (usually stipulated in international bidding), the bid opening, bid evaluation, bid selection and bid-winning notice shall be completed within the validity period of bid bond, and the contract shall be signed within the validity period of bid bond. In this way, the above problems will not occur.
