This manual provides a complete and comprehensive overview of the calculation, testing, and design of pile foundations and classifies pile systems in an application-oriented manner. It is based on Eurocode 7 and DIN 1054 edition 2010, as well as the European design standards DIN EN 1536 (bored piles), DIN EN 12699 (displacement piles), and DIN EN 14199 (micro piles). In addition, the present recommendations deal with pile system classification, pile actions due to structural loads, negative skin friction and lateral pressure, pile resistances from static and dynamic pile test loads, as well as extensive tables on the pile bearing capacity of almost all pile systems based on empirical values, pile groups, performance of static and dynamic test loads, as well as integrity tests, and bearing behavior and verifications.
