Second stage description

Adds a second stage object to the tender and lot objects, to describe the second stage of a two-stage procedure. In particular, it adds two fields to describe the limits on the number of candidates to be invited.

Guidance

If there is an exact limit on the number of candidates, set minimumCandidates and maximumCandidates to the same number.

If maximumCandidates is set, use the selection criteria extension (TBD) to describe how the selection criteria will be used to select candidates to be invited for the second stage.

Legal context

In the European Union, this extension's fields correspond to eForms BG-709 (Second Stage). For correspondences to Tenders Electronic Daily (TED), see OCDS for the European Union.
