Government Procurement Act Article 52

The award of contract conducted by an entity shall follow one of the following principles and the principle adopted shall be specified in the tender documentation:1. where a government estimate is set for the procurement, a tenderer whose tender meets the requirements set forth in the tender documentation and is the lowest tender within the government estimate shall be the winning tenderer;2. where no government estimate is set for the procurement, a tenderer whose tender not only meets the requirements set forth in the tender documentation with a reasonable price, but also is the lowest tender within the budget amount shall be the winning tenderer;3. the tenderer whose tender meets the requirements set forth in the tender documentation and is the most advantageous one shall be the winning tenderer; or4. to adopt multiple award. An entity may prescribe in the tender documentation that contracts may be awarded to different tenderers by different items or different quantities, but the spirit of competition as to the lowest price or the most advantageous tender shall be respected.Where the value of a procurement reaching the threshold for publication, and the subject of procurement is professional service, technical service, information service, social welfare services, or cultural and creative services, the award procedures of the most advantageous tender without setting a government estimate shall be applied in principle.Tenderers need not be notified to be present upon the award of contract, whereas they shall be notified of the outcome.
