Contracting authorities were invited to submit expressions of interest to a review panel made up of DG Regio, DG Home and Transparency International Secretariat. Their applications included a suggested public procurement process to monitor. This invitation included clear selection criteria based on which 17 projects were selected. In case of Greece, during the first phase of the project, there was a promotion through a series of meetings and briefings to a number of Managing Authorities (Ministries, Regions, Municipalities) that were selected based on projects’ budgets and type (construction, capacity building) as well as the population dynamic. More specifically, communication was established with the following authorities responsible for public works/public procurement: “Competitiveness, Entrepreneurship and Innovation”, “Infrastructure, Transportation, Environment, Sustainable Development”, “Human Resources, Training and Lifelong Learning”, “Public Sector Reform”, Attica Region, Macedonia Region, Municipalities of Athens and Thessaloniki. All authorities initially approached had a positive and constructive reaction but the authority that finally expressed interest to participate in the implementation phase of the IP through the selection of a particular project was the Managing Authority of Attica Region that submitted an application directly to DG Regio.
