Due to the World Tunneling Congress WTC 2020 changing the congress date to September 11-17, we have decided to reschedule ACUUS 2020 Helsinki Conference. 

ACUUS 2020 Helsinki Conference will be organized on February 2-4, 2021.

We wanted to react to the overlap of these two major events as soon as possible and we hope that the change of the date does not affect to your participation to the event. We are working hard to make the ACUUS 2020 Helsinki as succesful as possible and we now invite you to experience the real Finnish winter!

The abstract reviewing process will go on as planned and the notification emails will have been sent out!

We are however opening the call for papers for new submissions.

Deadline for new submissions is September 1, 2020.
