In this study, driving records of 18 open-ended steel tubular piles installed in dense sandy soil conditions at five sites in the Netherlands were utilized to evaluate models that are currently used in practice for predicting the static soil resistance during driving (SRD), as well as a recently developed method, known as the Unified Method. Since the Unified Method is a static axial capacity-CPT-based design method, slight modifications to the originally proposed formulas were examined to allow estimation of the SRD. This paper presents a modified format of the Unified Method and its performance is assessed by comparing predicted with measured hammer blow count profiles. It is eventually shown that the modified Unified Method leads to overall improved blow count predictions compared to current approaches.@en
