As part of the GEOLAB project, the Institute of Geotechnics of TU Darmstadt called geotechnical engineers from industry and academia to participate in an international Blind Prediction Contest (BPC) on the response of piles under monotonic and cyclic lateral loading. Two separate tests were performed on a hollow open-ended steel pile embedded in dry sand. One test under monotonic loading and the other under quasi-static cyclic loading with more than 10,000 loading cycles. This document summarises the outcomes of the BPC and announces the awarded teams. Only the members of the winning teams are disclosed, while the identities of other participants remain anonymous in accordance with the BPC rules.
