Because of the external cause of the mask, the state has been promoting electronic bidding for nearly 10 years. These two years of policy to promote the strength is more and more, I believe that the full implementation of electronic bidding is not far away.
Relative to the traditional paper bidding, electronic bidding is still very short, but the difference between online and offline, but also let a lot of bidders stepped on the "pit"? Now there is no need for others to report, a "check" to make the bidding and bidding become traceable.
1, the bidder's IP address or Mac address duplication
Surrounding the bidding situation, the bidding work of multiple vendors is dominated by the bidding behavior of the vendors to complete the bidding behavior, this time often all the bidding is the vendor's employees write, and may even be directly by a person to take a few companies' purchasing platform account, upload the bidding documents for the bidding, which led to the bidding of the IP address duplication, Mac address duplication.
Some people know this IP address duplication, in order to avoid IP address duplication, may be in the company inside the bidding, and then take the laptop at home or in the hotel to upload another company's bid, thought this is not a problem, in fact, at this time, the bidders Mac address is still the same, but also in vain.
2, the bidding supplier basic information duplication
For the same procurement project, the bidding supplier, there are two or more suppliers of basic information duplication, such as contact name, telephone, e-mail, company address and other content duplication;
Two or more suppliers shareholders there is an associated relationship, this is now a lot of third-party data companies can query.
There is also the company office space leaser or owner of the same place.
3, the tender announcement problem (short, part of the important information is not public)
In the case of public bidding, bidding procurement personnel in order to worry about a lot of competitive companies bidding registration, the bidding announcement time is set particularly short, so as to leave a potential supplier to register for a short period of time, short time to prepare the bidding documents to crowd out possible competitors.
Note: the announcement time in the government or state-owned units, there is a time limit requirements, private enterprises are relatively arbitrary.
4, the bidding documents are identical
The bidding documents are identical in nature. Through the software to compare the attributes of the bidding documents electronic documents, when the electronic bidding author of different companies, the last saved, the company and other content similar to the same, said it is likely to come from the same hand, there is a suspicion of bid-rigging.
The contents of the bidding documents are consistent. Usually manifested in the corresponding content of the technical bid, program details are the same, the bidding documents are the same flaws, such as typos are exactly the same. There are also low-level similarities, such as company A's bidding documents written in the name of company B, put company B qualification documents, etc., typically belong to the bidding documents Copy caused by the bidding, no doubt.
5, the tender price close to the measured price or internal maximum price
In the absence of public internal maximum price, by the bidder close to the measured price or internal maximum price to win the bid. The last winning bidder has been close to the maximum price of the bid, bid-rigging suspicion is very high.
6, suppliers accompanying the bid
To ensure full competition, the introduction of high-quality suppliers, public tenders or invitations to tender, will require a minimum number of suppliers bidding. Therefore, the bidding process, in order to meet the requirements of the number of suppliers bidding, some vendors will pull some "small partners" to accompany the bid. Usually each vendor's "partners" is fixed, when the bidding for many times, it will be found that several vendors in different purchases regularly appear at the same time, and the winning bidder is one of the fixed (bidding suspicion is very large), this situation alone look at a procurement project, it is difficult to find, need to analyze multiple projects.
7, the cut-off time period is short
In order to crowd out some of the suppliers, and cooperation with suppliers to communicate in advance of the demand, the program, so that the cut-off time is close to the bidding time, so that potential competitors programming time is very short, so as to achieve the purpose of crowding out.
8, the supplier bidding rate is abnormal
There are several vendors bidding several times, the winning rate is abnormally high, if the vendor is not the industry leader, the strength of the general or even poor, the suspicion of bid-rigging is very large;
There is also the same supplier is not a low price frequently won the bid.
9, the history of bidding anomalies indirectly generated by the suspicion
Many vendors think that when the bidding is very careful, will not find the problem, but in fact, it is not.
History of a bidding IP address or Mac address duplication, resulting in the two have been associated with the new project bidding process, even if very careful, the bidding process did not leave traces, but there will still be a problem, there is a suspicion of bid-rigging.
10, the offer list unit price anomaly
Some procurement offer a number of single items, the bidding process, after setting a bidding vendor price, to save time, the other bidding partner's price directly multiplied by a certain coefficient, which will lead to several bidding vendors, the offer situation, a regular decreasing or increasing.
