Published the headline article: "Electronic Bid Documents "Checked for Duplicate", 10 Details Expose Bidding Rigging"

On September 15, the General Office of the State Council issued the "Opinions on Further Optimizing the Business Environment and Reducing Institutional Transaction Costs of Market Entities", proposing to promote bidding, bidding, and bid opening in the field of engineering construction by the end of October 2022. Online processing of the entire business process and cross-regional and cross-platform mutual recognition of digital certificates in the fields of bidding and bidding.

Due to the external factor of masks, the country has promoted electronic bidding for nearly 10 years. The policy advancement in the past two years has been getting stronger and stronger, and I believe that the full implementation of electronic bidding is not far away.

Compared with traditional paper bidding, the duration of electronic bidding is still very short, but the differences between online and offline have also caused many bidders to step into "pits"? Now there is no need for others to report, and a single "check for plagiarism" makes bidding rigging and collusion traceable.

1. The IP address or Mac address of the bidder is duplicated

In the case of bid rigging, the bidding work of multiple manufacturers is completed by the manufacturer that dominates the bid rigging behavior. At this time, the bid documents are often They are all written by employees of this manufacturer, and a certain person may even directly use the procurement platform accounts of several companies to upload bidding documents for bidding, resulting in duplicate IP addresses and duplicate Mac addresses of bidders.

Some people know about duplication of IP addresses. In order to avoid duplication of IP addresses, they may bid in a company and then upload another company’s bid at home or in a hotel with a notebook, thinking that this is no problem. In fact, the bidder's Mac address is still the same at this time, which is in vain.

2. Duplication of basic information of bidding suppliers

For the same procurement project, two or more suppliers have duplication of basic information, such as contact name, Duplicate content such as phone number, email address, company address, etc.;

Two or more supplier shareholders are related, and there are many third-party data companies that can query this.

There is also the lessor or owner of the company's office space.

3. Problems with bidding announcements (short time, some important information is not disclosed)

In the case of public bidding, bidding and procurement personnel are worried about many competitive companies signing up for bids. , the bidding announcement time is set to be very short, so that potential suppliers have a short time to register and prepare bid documents, and squeeze out possible competitors.

Note: The announcement time is required by the government or state-owned enterprises within a time limit, while private enterprises are relatively casual.

4. The bidding documents are identical

The bidding documents have the same attributes. By comparing the properties of electronic bid documents through software, when the authors, last savers, companies, etc. of electronic bidders from different companies are similar, it means that they are likely to be from the same hand, and there is suspicion of bid rigging.

The contents of the bidding documents are consistent. Usually, the corresponding content and plan details in the technical bids are the same, and the flaws in the bidding documents are the same, such as typos. There are also low-level similarities, such as company A’s bidding document containing the name of company B, and including company B’s qualification documents, etc. These are typically caused by copying of bidding documents, and there is no doubt about bid rigging.

5. The bid price is close to the estimated price or the internal maximum price

When the internal maximum price is not disclosed, the bidder will win the bid if it is close to the estimated price or the internal maximum price. The final winning bidder won the bid when it was close to the maximum price, and the suspicion of bid-rigging was high.

6. Supplier accompanying bidding

In order to ensure full competition and introduce high-quality suppliers, a minimum number of bidding suppliers will be required during public bidding or invitational bidding. Therefore, during the bidding process, in order to meet the requirements for the number of bidding suppliers, some manufacturers will bring in some "little partners" to accompany the bidding. Usually, each manufacturer has a fixed “partner”. After bidding multiple times, you will find that several manufacturers often appear at the same time in different procurements, and the winning bidder is always one of them (the suspicion of bid rigging is high) ), this situation is difficult to find by looking at a single procurement project, and multiple projects need to be analyzed.

7. The bid closing time is short

In order to exclude some suppliers, communicate needs and plans with cooperative suppliers in advance, so that the bid closing time is close to the bid issuance time, so that potential competitors can use their plans The preparation time is extremely short, thereby achieving the purpose of crowding out.

8. The supplier’s bid-winning rate is abnormal

Some manufacturers have won several bids several times, and the bid-winning rate is abnormally high. If this manufacturer is not the industry leader and has average or even poor strength, Bidding rigging is highly suspected;

The same supplier frequently wins bids at non-low prices.

9. Suspicion indirectly caused by abnormal historical bidding

Many manufacturers thought that they paid close attention to the bidding and would not find any problems, but this is not the case.

The IP address or Mac address of a historical bid is repeated, causing the two to be associated. During the bidding process of a new project, even if care is taken to ensure that no traces are left during the bidding process, Problems will still arise and there will be suspicions of bid-rigging.

10. The quotation list price is abnormal

Some procurement quotations have a large number of items. During the bidding process, after setting the price of a bidding manufacturer, in order to save trouble, the price of another bidding partner is The price is directly multiplied by a certain coefficient, which will cause the quotations of several bidders to decrease or increase regularly.
