Tactics
When contracts were awarded in this country and sector, there was usually a single bid in the end. A solid bid has a real chance here. (Based on 4,416 completed awards — not a statement about this procedure.)
This procedure allows 62 days between publication and deadline — typical in this country is 32 (median of 20,496 procedures). Much more generous than usual — time for a thorough bid rather than a quick one.
The deadline falls on a Monday — your last full working day is the Friday before. Have evidence and guarantees together by Thursday.
Foreign bidders
In Germany · Security & defence, 110 contracts went to foreign companies over the last 3 years (of 4,697 recorded awards) — mostly from Austria, France, Netherlands.
