Suitable for corporate self-financed projects or for enterprises without experience in independent bidding, where the bidding results need to be reported to higher authorities for review or internal record-keeping.

Bidders and tender intermediaries must pre-qualify entities or organizations showing interest in bidding, and must also publish a pre-qualification announcement in newspapers or other media. The pre-qualification announcement should include the following:

(1) Name and address of the bidder;

(2) Nature and quantity of the bidding project

(3) Location and time requirements for the bidding project;

(4) Methods for obtaining pre-qualification review documents.

(5) Location and Time

(6) Fee for requesting pre-qualification documents

(7) Location and deadline for submitting the pre-screening application for qualification.

(8) Other matters to be informed for pre-qualification review.

The above pre-qualification mainly reviews the corporate legal entities or organizations interested in bidding, and it should be checked whether they are capable of fulfilling the contract fully. Corporate legal entities or organizations interested in bidding should submit proof of their capability to fulfill the contract fully, in the form of documents or materials, to the bidder or the bidding intermediary. The bidder or the bidding intermediary should make a pre-qualification decision on the corporate legal entities or organizations that have submitted an application for pre-qualification. Under the bidding schedule plan, the engineering bidder should submit a bid invitation letter to corporate legal entities or organizations that generally have an interest in bidding from three or more parties, or to those that have passed pre-qualification.
