Eurocode 3 - Design of steel structures - Part 5: Piling

Continuing the evolution of the Eurocodes, EN 1993-5:2025 provides in-depth rules for the structural design of steel bearing and sheet piles used in foundations and retaining structures. This standard is applicable to both temporary and permanent civil works on land and over water, ensuring best-practice approaches for durability and mechanical performance.

Core aspects include:

• Specification and performance criteria for various types of steel piles
• Methods for design by calculation and by testing
• Integration with other relevant Eurocodes (e.g., EN 1990, EN 1991, EN 1997)
• Exclusion of geotechnical and seismic design (delegated to other standards)

This standard is a must for civil and structural engineers, as well as contractors involved in foundation design, especially in complex or high-risk environments. Adoption also means improved compliance with European and international construction norms.

Key highlights:

• Covers both piling foundations and retaining structures
• Enables both calculation and test-assisted design methods
• Ensures compatibility and integration with broader Eurocode family
