On 8 and 9 May 2018 large diameter HEK tube piles, part of the foundation of the Sonate-Adagio building in the inner-city of The Hague, The Netherlands, were tested  by means of a Rapid Load Test (StatRapid). The tests on these test piles were conducted in accordance with the new NPR7201 (2017).

In addition to measurements at the pile head, additional measurements were taken along the pile shaft and at the pile toe by means of sister bars. An extensive article on these tests will be available at the end of 2019.
