Tactics
When this buyer has awarded in this sector, there was usually a single bid in the end. A solid bid has a real chance here. (Based on 3 completed awards — not a statement about this procedure.)
This procedure allows 43 days between publication and deadline — typical in this country is 34 (median of 2,398 procedures). Much more generous than usual — time for a thorough bid rather than a quick one.
Foreign bidders
In Greece · Construction work, 132 contracts went to foreign companies over the last 3 years (of 55,142 recorded awards) — mostly from Italy, Germany, Albania.
Submission language: Greek.
