Bidders are the main participants in the profit competition in the engineering construction market, and improving the winning rate is the common goal of every bidder. At present, the builders in some areas have gradually formed the "Hedgehog Theory" in the process of long-term competition, and the interests of "outsiders stand aside", "everyone has a share" and "everyone has food" are the same. They ignored the law and won the bid by illegal means, especially those who were greedy and mercenary. For their own economic interests, they try their best to do whatever it takes. These "dirty tricks" of bidding boil down to "five methods":

Catch turtles in a jar

There are several bidding competitions in a bid section or package section, one of which is the main one and the others are accompanying bids. No matter which company wins the bid, it is built by the main contractor or supplied by the main supplier, so it is often called the containment method. This dirty trick often appears in bidding projects.

Divide and conquer method

Also known as one-by-one infiltration method, through coercion, inducement and other means, the shortlisted potential bidders are "communicated" respectively, and their bid quotations are limited to above the specified amount. All expenses incurred by all bidders due to the bidding project shall be borne by the winning bidder of Communication.

Take turns to do village law

They often form alliances with tendering agencies. As long as an organization bids for a project, basically a fixed number of companies or distributors A, B, C and D participate in the bidding. You accompany me once, and I will accompany you once. Reciprocal communication does not hurt each other. The expenses incurred during the period shall be compensated by the winning bidder, and everyone has a benefit fee; There are also projects that are offset by the number of times, without mentioning each other's financial accounts. Whole packet segmentation method

In the case of large-scale or multi-project projects, several builders who participated in the bidding secretly agreed that after reaching an agreement on the quotation and division content of "cake" and determining the quotation of the winning bidder, others would participate in the competition, but the quotation should not be lower than the contract price; When bidding, we don't know each other and do our own things to avoid being noticed.

Cicada shelling method

Compared with the second successful candidate, the quotation of the first successful candidate is much different, far more than the bid bond given by the first successful candidate to the tenderer. The first and second successful candidates secretly negotiate the compensation fee for bid cancellation (generally including the paid bid bond, travel expenses, entertainment expenses, bid preparation fees, net profit involved in project bidding, etc.). ). After negotiation between the two parties, the first successful candidate ignores the bid-winning notice issued by the tenderer, and after the deadline, he will only abandon the bid for an excuse and be willing to accept the tender. Therefore, it is also called the profit method of abandoning the bid.

The main reason for this situation is that the construction party doesn't know much about the bidding law and supporting rules and regulations, and the bidder doesn't have a strong sense of confidentiality about important links. At the same time, it is also very important for the regulatory authorities to investigate and deal with the illegal acts of bidding builders, and local government protectionism encourages those who violate the law.
