ABSTRACT
Piles have been used all over Europe for many years to carry the loads of various structures through soft soil layers to soil strata with high bearing capacity. However looking on the national codes today there is a wide variation from country to country regarding pile types, design — and control methods and safety philosophy. The work has been in progress for many years and experience shows that it is difficult job to harmonise design methods and traditions for pile foundations in the involved countries. However when the topic is discussed amongst engineers, it is an advantage to have at least a brief knowledge how piling is carried out in other countries. For structures with pile foundations, boring are usually performed to a depth which ensures knowledge of soil conditions well below the level of pile base, and to an extent sufficient to permit a design evaluation of bearing capacity and negative skin friction.
