Overview
EN 1997-2:2024/prA1, also known as Eurocode 7 - Geotechnical design - Part 2: Ground properties, is a draft European standard developed by CEN (European Committee for Standardization). This standard provides comprehensive rules for determining ground properties essential for the design and verification of geotechnical structures, including buildings, earthworks, and foundations. It forms a key part of the second generation of Eurocodes, which are used widely in the construction and civil engineering industries across Europe.
The document specifies the requirements and guidance for:
- Planning and conducting ground investigations,
- Collecting and evaluating data on ground properties and groundwater conditions,
- Preparing an accurate Ground Model,
- Selecting appropriate field and laboratory test methods,
- Reporting and presenting results in the Ground Investigation Report.
This standard is intended for conjunction with other critical Eurocodes, including those addressing general geotechnical design and seismic considerations.
Key Topics
EN 1997-2:2024/prA1 addresses several central aspects of geotechnical investigation and ground property determination:
- Ground Investigation Requirements: Procedures and documentation to plan and execute subsurface investigations.
- Data Collection: Guidelines for gathering geotechnical and groundwater information.
- Ground Model Preparation: Steps to develop a comprehensive framework representing subsurface conditions.
- Field and Laboratory Testing: Criteria for selecting and carrying out appropriate tests to derive significant ground property values.
- Result Presentation: Standards for summarizing findings and presenting derived ground property values in the Ground Investigation Report.
- Terminology Updates: Several definitions and references are updated for clarity and harmonization with related standards.
- Editorial Improvements: Numerous updates to terminology (e.g., replacing "abrasivity" with "abrasiveness") and alignment with recent versions of related standards.
Applications
The practical value of EN 1997-2:2024/prA1 is significant within the field of civil and geotechnical engineering. Its requirements and guidance are critical for:
- Foundation Design: Determining soil and rock properties for safe, efficient design of building and infrastructure foundations.
- Earthworks and Excavations: Assessing conditions for embankments, cuttings, and other ground modifications.
- Underground Construction: Ensuring safe design parameters for tunnels, basements, and subsurface structures.
- Seismic Engineering: Collecting ground property data critical for structures exposed to seismic activity.
- Groundwater Assessment: Understanding site-specific groundwater conditions for dewatering and foundation integrity.
- Preparation of Ground Investigation Reports: Providing engineers, contractors, and regulatory authorities with standardized, reliable geotechnical data.
Implementing this standard enhances safety, increases design reliability, and supports regulatory compliance across a wide range of construction and civil engineering projects.
Related Standards
EN 1997-2:2024/prA1 is designed to be used alongside several related Eurocode standards, ensuring integrated and comprehensive geotechnical design:
- EN 1990 (all parts): Basis of structural and geotechnical design.
- EN 1997-1:2024+A1:2026: General rules for geotechnical design and verification.
- EN 1997-3:2025+A1:2026: Specific rules for certain types of geotechnical structures.
- EN 1998-1-1:2024+A1:2026: Requirements for ground properties in seismic action definition.
- EN 1998-5:2024+A1:2026: Rules for geotechnical design in seismic regions.
- Forthcoming Eurocodes: Ongoing development of standards for glass, fibre-polymer composites, and membrane structures enhances the cohesive application of structural design codes.
By adhering to these harmonized Eurocodes, stakeholders ensure best practices in ground investigation, safety, and structural reliability throughout the European construction sector.
