Tenders since 2011
By year of publication, each notice once. Up to 2023 from the EU Official Journal (TED, only above the EU thresholds, buyer key “stadt hennef sieg”), from 2024 from the DÖE, so that nothing in 2022 and 2023 is counted twice. Portals: open tenders from procurement portals beyond the DÖE, since 23 Sep 2026. Archive: national tenders from snapshots of the portals in the Internet Archive and from official gazettes, all in the past; an EU-wide procedure can appear there and in TED. The current year is incomplete.
Lots per quarter, 12 quarters
