(PPA)

¹ In the se­lect­ive pro­ced­ure, the con­tract­ing au­thor­ity is­sues a pub­lic in­vit­a­tion to tender and in­vites the ten­der­ers to sub­mit a re­quest to par­ti­cip­ate first.

² The con­tract­ing au­thor­ity se­lects the ten­der­ers that may sub­mit a tender based on their eli­gib­il­ity.

³ The con­tract­ing au­thor­ity may lim­it the num­ber of ten­der­ers per­mit­ted to tender, provided that ef­fect­ive com­pet­i­tion is main­tained. If pos­sible, at least three ten­der­ers are per­mit­ted to sub­mit tenders.
