This procedure is often used for complex contracts such as large infrastructure projects where the public authority cannot define the technical specifications at the start. After the publication of the contract notice, interested businesses have 37 days to request participation. The public authority must invite at least 3 candidates to a dialogue in which the final technical, legal and economic aspects are defined. After this dialogue candidates submit their final tenders.
Note: Competitive dialogue cannot be used by public services providers in the water, energy, transport and postal services sectors.
