The bidder in the procurement documents set the conditions are not cut itself, resulting in too few bidding units to meet the conditions; the performance of the bidders is too high; the requirement of the original system or equipment for seamless docking. Original equipment suppliers are bound to have a clear competitive advantage; the required delivery period is too tight, no prior homework suppliers can not be completed.
This may be bidders do not carefully read the tender documents, not according to the requirements of the sealing seal, wrong or mixed packaging, forget to cover the seal at the seal; in addition, there are bidders are not required to provide a bid bond, the requirement to provide a bank draft, but to provide the wire transfer vouchers; there are also some bidders qualification review of the materials required, only with the original, there is no copy of the bidding documents.
The evaluation of the evaluation committee is not careful, the bidding unit review is not strict, once there is a complaint, the bidder has to re-tender. The technical parameters of the winning candidate did not meet the bidding requirements, but the evaluation did not find out, and later found out, had to cancel the winning candidate's qualification for winning the tender. In fact, these are small details in the bidding process, but if something goes wrong, it will have the same adverse impact.
While this is not common, it does happen, for example, some projects are really special, originally meet the requirements of the supplier is only one or two, but according to the open bidding procurement; some projects also really need to docking with the original system or equipment, the use of a single-source procurement method is more appropriate. I believe that as long as seriously, this situation can be easily avoided.
