Scorecard

The buyer in figures

How it runs its calls for tender

usual bidding window
27 days
of its calls state an estimated value
0%
How we count

Estimates over its calls for tender of the last 3 years, bidding windows over the last 2. Deadline extensions only where the source updates a notice in place (TED publishes corrections as separate notices, so its buyers show none).

Who wins its contracts

Many suppliers
different companies won its awards
19
of the awards went to the three most frequent winners
32%
of its calls state an estimated value
0%
How we count
Based on 25 awards with a named winner over the last 3 years. Counted by award, not by value, because lot and framework amounts are not comparable. Concentrated means the three most frequent winners took 65% or more of the awards; many suppliers, under 35% with at least ten different winners.

Competition

tenders per lot on average (open and restricted procedures)
1.9
of those lots received a single tender
10%
of the awards went to companies based in another country
0%
How we count
As the official award notices state them, over the last 3 years. Tenders per lot count open and restricted procedures only: in a negotiated procedure or a direct award a single tender is the procedure itself. The country is the one the notice gives for the winner.
