Execution should always be supervised by a geotechnical expert to ensure adherence to these guidelines:
The "Recommendations on Piling" (EA-Pfähle) is a globally recognized handbook by the German Geotechnical Society that serves as the definitive guide for designing and constructing pile foundations. It aligns with Eurocode 7 and DIN 1054 standards, covering everything from single bored piles to complex piled raft foundations . Core Technical Principles Recommendations on Piling
: Design is based on the partial safety factor approach, differentiating between Ultimate Limit State (ULS) —ensuring the pile doesn't fail—and Serviceability Limit State (SLS), which controls settlements and deformations. Execution should always be supervised by a geotechnical
The recommendations focus on ensuring both structural stability and long-term durability through standardized practices: such as foundation loads
: When piles are placed closely together (forming a group), the guide requires designers to account for reduced individual capacity and increased settlement due to mutual interaction. Critical Installation Standards
: It distinguishes between different types of actions, such as foundation loads, negative skin friction, and lateral pressure . Specific verifications are required for cyclical, dynamic, and impact loading.
