Enforcement Rules of the Government Procurement Act Article 44

Where an entity adopts multi-step opening of tenders pursuant to paragraph 1 of Article 42 of the Act, it may prescribe that tenders of the qualification, specification, and price be submitted and opened in steps, or be submitted in one step but opened in steps, except that qualification documents shall only be submitted in one step under the selective tendering procedures.The sequence of tender opening under a step by step procedure referred to in the preceding paragraph may be in the sequence of qualification, specification, and price, of which the qualification and specification can be combined into one step, so do the specification and price.Where a tenderer fails to pass the tender review in a prior step of multi-step tendering, it shall not be permitted to tender in the next step. Where a tenderer fails to pass tender review in a prior step of multi-step opening of tenders under one step tendering, the rest of the tenders submitted by the tenderer shall be returned unopened.Where there are three or more qualified suppliers submitting their tenders in the first phase of multi-step tendering pursuant to the requirements prescribed in paragraph 1 of Article 48 of the Act, the threshold of three tenders may be inapplicable for the subsequent steps of tender opening.In the event of multi-step opening of tenders under one step tendering, suppliers shall have each tender sealed separately for each step of tender opening.
