The coexistence period of old geotechnical standards based on a global safety system parallel to Eurocodes ended in Austria by June 2009. Therefore specific case histories of projects designed according to Eurocodes, especially to EC 7-1 are not yet available. The authors of this paper were dealing with several river bridge foundations using large diameter bored piles during the last decades. So they try to show the difference between the design of such pile foundations based on the tradition in Austria, especially using often only a SLS design, and the new approach according to EC 7-1 by means of examples of Danube River bridges in eastern Austria already built several years ago, of one such bridge construction which is now under execution and of one river bridge project abroad in southeastern Europe, close to the Danube River. The types of pile foundations to be presented in this paper are different as follows: single piles combined to pile yokes, pile groups as usual and box-shaped pile groups for bridge piers in the river-bed. Concerning box-shaped pile foundations it will be shown that additional definitions which are neither given in EC 7-1 nor in its NA for Austria are necessary for the design. Finally some data on the behaviour of these pile foundations shall be presented.
