information with all stakeholders. The
program will include contemporary
research and lessons learned, and will also
focus on defining the future of deep
mixing. Registration for the event is open.
Learn more at www.dfi.org/DM2021.

Particular attention shall be paid to
instrumentation, the rules for testing, results
interpretation and benefits. Recent pile load
test campaigns will be used to illustrate
discussions. More information will be
available in the next edition of DFI Europe's
Regional Report and at www.dfieurope.org.

Pile Load Testing Seminar 2021
As announced in the May/June edition of
Deep Foundations, DFI Europe is organizing a
seminar on pile load testing in collaboration
with the Royal Institute of Engineers (KIVI)
in the Netherlands. This seminar has also
been postponed due to COVID-19 and will
now occur in fall 2021. It will provide the
state-of-the-art understanding of static load
tests in compression, tension and laterally
loaded piles as well as rapid and dynamic

tests. The subject will be covered from the
point of view of the client, the contractor, the
test labs and the regulatory authorities from
various European countries and beyond.

After a successful conference in Rome in
2018, preparation for the next DFI-EFFC
Conference has started, with active
conference working groups. The event will
be held at the Free University of Berlin,
from Wednesday, May 18, to Saturday, May
21, 2022. More information will follow
soon, but save these dates!

Another project, Terraced Tower, was
executed in Rotterdam, the Netherlands.
The Terraced Tower is a unique project
running alongside the river Maas. The
apartments along the face of the building
have a panoramic view over the river. For
this project, over 400 vibro piles with a
diameter of 609 mm (24 in) were installed.
These piles varied in length from 20.5 - 26.0
m (67 ft - 85 ft) and were installed under
heavy soil conditions. These heavy conditions were caused by the high grade of compaction and subsoil obstacles. Nevertheless,
the project was successfully realized.
