1, leakage law
Disclosure of relevant information of other bidders, disclosure of pre-tender estimate, disclosure of bid evaluation, disclosure of the list of key personnel such as members of the Qualification Examination Committee or the Bid Evaluation Committee.
2. Special customization method
Tailor-made terms with obvious tendentiousness for a bidder to control bidding, and conduct "substantive negotiation" with a supplier before the deadline for submitting bidding documents, so that the bidder can supplement, replace or change the bidding documents and change the quotation (including modifying the relevant data of electronic bidding documents).
3, do bureau method
Before bidding, the winning bidder has been appointed by default, and bidders have been organized to collude in bidding to lower or raise the bidding price. For example, the tenderer will split a given tender into multiple tenders, and then arrange the designated winning bidder in different tenders, so that the interests of all parties can be shared, and other unsuccessful bidders can make separate agreements with the tendering agency. For example, the tenderer instructs his unqualified companies to negotiate with qualified companies and bid in the name of qualified companies. After winning the bid, the unqualified company will perform the contract.
4, instigation, suggestion method
Instruct, imply or force the bid evaluation committee to give tendentious guidance, and instruct the tendering agency to provide help to the default winning bidder and treat it differently.
5. Price method
Adopt fraudulent means to win the bid at a low price far below the cost price, and then raise the final settlement price by changing the service volume during the project implementation.
Step 6 play dumb
The tenderer found a bidder's representative and signed the names of multiple bidders on the bid opening record, but it did not prevent the tenderer from finding that the legal representatives, entrusted agents, project leaders, project leaders and other personnel of different bidders paid social insurance in the same unit, but agreed to continue to participate in the bidding. The tenderee finds that there are multiple stakeholders with the same person or interest. Turning a blind eye to the situation of fraudulently using the enterprise information of more than two bidders to participate in qualification examination, receiving bidding information or attending bidding question-and-answer meeting on behalf of more than two bidders, and agreeing to continue to participate in bidding. The tenderer does not stop the mixed bidding information (including electronic information) of different bidders during qualification examination or bid opening, but agrees to pass the qualification examination or continue to participate in bid evaluation and bid opening, and turns a blind eye to obvious signs of cross-bidding.
7. Unscrupulous methods
For the project evaluated by the lowest bid evaluation method, after the unsuccessful company raises a question, the tendering and purchasing unit still maintains the original bid evaluation result after reconsideration, and the tenderer refuses to sign a contract with the successful candidate without justifiable reasons.
