The channel tunnel did have a cost overrun, by 80% if I remember correctly.

more like 100%

Gotthard_Base_Tunnel:

The total projected cost of the project was 9.8 billion Swiss francs (€8.85 billion, US$10.3 billion[14]); the final cost exceeded $12 billion.

That imho is rather good. ( and for a nontrivial project at that.)

compare to the New Hamburg "Elbphilharmonie"

IMU it is more than 250%
€186m --> €600+m


So it appears to not be  impossible to give reasonable cost estimates.
if you observe some professional hygiene.
i.e. shoot politicians and marketeers on first sight.
