Prequalification. The bidder shall fill in the "Pre-qualification Form" prepared by the tenderer, including the business scale, personnel and facilities, engineering records, etc. , and provide relevant supporting documents and materials.

Prepare building documents. At the beginning of the tender, the tenderee shall organize relevant personnel to prepare the tender documents, and explain the technical conditions and trade conditions of the purchased goods or contracted projects. ?

Bid preparation. After the bidder wins the bid. We should check the quality, technical standards, delivery date, engineering quantity and progress of goods or projects in strict accordance with the bidding conditions, and estimate whether they can fully meet the bidding requirements and make competitive quotations in combination with their own conditions and market competition. ?

Prepare the tender and implement the guarantee. A tender is an irrevocable offer made by a bidder to a tenderer. Its main contents include the confirmation of bidding conditions, related indicators and project progress of commodities or projects, technical descriptions and drawings, responsibilities that bidders should bear, total price and unit price analysis tables, etc. In order to prevent the bidder from refusing to sign the contract after winning the bid, the tenderer usually requires the bidder to submit a bid bond, which is generally 3% ~ 10% of the total price. Bank guarantee or standby letter of credit can also be used instead of cash. Therefore, the bidder should implement the guarantor before bidding. ?

Submit the bidding documents. The tender documents include the tender, tender guarantee or standby letter of credit, attachments related to individual descriptions in the tender and other necessary documents. The bidding documents shall be sealed and delivered to the designated place within the specified time, and the submission method can be submitted by special person or registered mail.

Bid opening. The tenderer shall open the sealed tender documents in public at the time and place announced in advance, read out their contents, and allow the bidders present to record or record. After the bid opening, the bidder shall not change the contents of the bid. The bid opening is a form of publicizing the contents of the tender to ensure the fairness of the tender work, rather than determining the winning bidder on the spot. ?

Bid evaluation and award. In addition to price, technical quality, project schedule or delivery cycle, and services provided will all affect the bidding quality. The tenderer must review and compare the bids, and then select the best candidate to win the bid. Its main work is as follows:

(1) Review the bidding documents. Whether its content meets the requirements of the tender documents, whether the calculation is correct and whether the technology is feasible.

(2) Comparing the trading conditions of bidders, the winning bidder can be determined by item-by-item scoring, collective evaluation or voting. The preliminarily determined candidate for winning the bid may be one or several alternative candidates.

(3) Review the qualification of the winning bidder. If the first winning bidder passes the review, it will become the winning bidder of this tender. Otherwise, review the alternate winning bidders in turn. In any of the following circumstances, the tenderee may declare the tender failed and reorganize the second round of tender: too few bidders participated in the tender, and all the bids did not meet the tender requirements; The bid price is obviously higher than the average price in the international market.

Winning the bid and signing the contract. After determining the winning bidder, the tenderer shall notify the winning bidder in writing to sign the contract at the place where the tenderer is located within the prescribed time limit, and pay the performance bond or use the bank guarantee as the performance guarantee.
