The bid document is prepared by the bid-issuing unit or commissioned by the design unit to provide bidders with the main technical, quality, construction period and other requirements for the project. The bid document is a legally binding and enforceable bidding standard document that all parties involved in the procurement process must abide by during the bidding process. It must be logical and not inconsistent or ambiguous; the terms must be concise and brief. The bid document is also the basis for the bidders to prepare the bid document. The bidder must make a substantial response to the content of the bid document, otherwise the bid will be judged as invalid.

The bid document is also the most important basis for bid evaluation. Tender documents generally follow the principles of openness, fairness, and impartiality. Only fairness and openness can attract truly interested and competitive bidders to compete. Only by achieving the purpose of procurement through competition can the interests of the user unit and the country be truly safeguarded. As a tendering agency, the most important task is to prepare and review bids and determine whether they contain discriminatory clauses. As the government bidding management department, the supervision department manages and supervises the bidding work. The most important task is to review whether there are discriminatory clauses in the bidding documents, at least one original, two or more copies.
