Dear Colleagues,

This is an update of the Araquari prediction event. The polymer-base bored pile has been successfully tested at Araquari, reaching a bearing capacity of approx. 860tons.

Out of the 72 worldwide participants in the prediction event, 62 predictions have been considered valid and compared in our statistical analysis. We have selected 3 predictors as winners.

A summary of results is presented in the attached file.

We would like to take the opportunity to express our gratitude for all participants.

Please join us in congratulating our three (3) winners:

  • Francesco Basile, Geomarc Ltd, Italy
  • Dean Harries, Geotechnical Specialist, CH2M HILL, USAMehari Weldu,
  • Graduate Student, University of Kansas, USA

Ongoing research will allow for detailed interpretation of testing data.

We recall that four (4) out of the six (6) piles have already been tested. Details will be available at, including the actual data of the prediction event tested pile.

Comments, critics and contributions are welcome.
