OBS_VALUE: Public procurement contracts falling under certain value thresholds are not subject to the GPA and are governed by the general public procurement laws applicable, respectively, to central and local government entities. Under local government procurement law, qualification criteria require tenderers to have their offices located in a specific city (local entity requirement), if such an additional requirement is regarded as appropriate and reasonable. The laws regulating central government procurement do not explicitly prohibit requiring suppliers to have offices in a specific city. Also, purchases under certain thresholds are allowed to undergo Designated Competitive Bidding or Negotiated Contracts instead of Open Competitive Bidding (Tender). There is more discretion given to the contracting authority in selecting the prefered providers below the threshold. In some cases, contracting authorities may set up their own rules or contract directly with providers.
