Pile Driving Monitoring with Pile Driving Analyzer® on driven steel tube piles Ø813mm and Ø1016mm, approx. L=50-60m, on pier 1 expansion in Port of Koper is being performed by our engineers. Pile Driving Monitoring is performed to define pile driving criteria with Junttan HHX160 hammer. Later re-driving tests are performed to control long-term pile capacity.
