EN 1990-2:2026/prA1 is a CEN draft amendment to Eurocode - Basis of structural and geotechnical design - Part 2: Assessment of existing structures. It specifies provisions for assessing existing structures, including geotechnical structures, and the general principles for interventions, for use with prEN 1990-1.

What does EN 1990-2:2026/prA1 specify?

EN 1990-2:2026/prA1 sets the Eurocode framework for assessment of existing structures and the actions and principles used in that assessment. It also sets clear limits: new structural parts to be integrated into an existing structure are treated under prEN 1990-1, and seismic assessment and retrofitting are directed to EN 1998-3.

The amendment is organized as updates to the front matter and Clauses 0 to 6, plus Annex A and Annex G, and it adds a new informative Annex J.

Annex	What it covers
Annex A	Application rules
Annex G	Basis of assessment for bearings
Annex J	Assessment assisted by numerical methods

What are the key requirements of EN 1990-2:2026/prA1?

EN 1990-2:2026/prA1 keeps the document tied to the general reliability principles of prEN 1990-1, and it says that prEN 1990-1 applies unless this document states otherwise. In practice, users start from the base Eurocode rules and then apply the assessment-specific provisions here.

General assessment framework

• Clause 0 adds Annex J to the list of informative annexes, so numerical methods are part of the document structure.
• Clause 1 keeps the scope focused on existing structures and interventions, not on the design of new structural parts.
• Clause 4 reinforces that the general rules apply only within the scope of this document.
  In practice, this tells the user when EN 1990-2 is the governing assessment document and when another Eurocode part must be used.

Actions and related Eurocodes

• Clause 2 expands the normative references to the main Eurocode families: EN 1991, EN 1992 to EN 1999, and EN 19100.
• Clause 4 also points directly to those parts for related design and assessment rules.
  This matters because an assessment often depends on the structural material, the geotechnical situation, or the action model being checked.

Assessment principles and updating

• Clause 5 adjusts the principles of assessment and the conditions for using them.
• Clause 6 concerns basic variables and updating, which is the part of the document used when existing information is revised by inspection, testing, or new evidence.
  In practice, this is the section a reader uses when deciding what data must be checked again and what can be updated for the assessment.

Annex-specific guidance

• Annex A gives application rules, including wording updates on service lives.
• Annex G covers the basis of assessment for bearings and adds a National Annex note on when the informative annex may be used.
• Annex J gives supplementary guidance for assessment assisted by numerical methods, including finite element (FE) methods and other numerical modelling techniques.
  This is the part to use when the assessment is supported by calculations rather than only by simplified checks.

What terms does EN 1990-2:2026/prA1 define?

EN 1990-2:2026/prA1 uses the standard Eurocode terms for assessment work and adds emphasis to a few practical ones.

• Assessment - the checking of an existing structure under the principles and rules of this document.
• Existing structures - structures already in place, including geotechnical structures.
• Interventions - actions taken as a result of an assessment.
• Actions for assessment - the load and action basis used when checking an existing structure.
• National Annex - the national document that controls national choice for informative annexes and related values.
• Finite element (FE) methods - numerical modelling techniques covered by Annex J for structural and geotechnical applications.
• Load testing - testing used as part of the assessment process and referred to in Clause 3 wording.

Who uses EN 1990-2:2026/prA1?

EN 1990-2:2026/prA1 is used by structural engineers, geotechnical engineers, assessment specialists, asset owners, and checking authorities involved with existing structures. It is relevant when a team must decide how to assess an existing structure, what data to update, whether to use numerical methods, and how to link the assessment to the wider Eurocode set.

It also matters for organisations that manage inspections, load testing, and technical reviews of existing civil engineering works and buildings. Annex G and Annex J are especially useful for specialists dealing with bearings and numerical modelling.

What changed in EN 1990-2:2026/prA1 from the previous edition?

EN 1990-2:2026/prA1 will amend EN 1990-2:2026 with a mix of editorial and technical updates.

• Adds Annex J to the list of informative annexes.
• Updates the scope note to refer to EN 1990-1.
• Revises the normative references to EN 1990-1:2023+A1:2026 and adds the main Eurocode families and EN 19100.
• Updates the Clause 3 example wording to refer to load testing.
• Adjusts Clause 4 and Clause 5 wording on general rules and principles of assessment.
• Tidies Clause 6 formatting on basic variables and updating.
• Updates Annex A wording, including the service lives note and the reference to towers, masts and chimneys.
• Adds a National Annex note to Annex G.
• Adds a new informative Annex J on assessment assisted by numerical methods.

Which standards are used with EN 1990-2:2026/prA1?

EN 1990-2:2026/prA1 is used with the main Eurocode parts named in its normative references and scope notes.

Standard	What it contributes
EN 1990-1:2023+A1:2026	Basis for new structures; default rules unless EN 1990-2 says otherwise
EN 1991 (all parts)	Actions on structures for assessment
EN 1992 to EN 1996 (all parts)	Material-specific structural rules for concrete, steel, composite steel and concrete, timber, and masonry
EN 1997 (all parts)	Geotechnical design rules
EN 1998 (all parts)	Earthquake resistance rules; EN 1998-3 is singled out for seismic actions and retrofitting of existing structures
EN 1999 (all parts)	Aluminium structures
EN 19100 (all parts)	Glass structures

What does the EN 1990-2:2026/prA1 document contain?

EN 1990-2:2026/prA1 contains the amendment text for the introduction, scope, normative references, terms and symbols, general rules, principles of assessment, and basic variables and updating. It also updates Annex A and Annex G, and adds Annex J on numerical methods.

The new Annex J gives supplementary guidance for assessment using finite element methods and other numerical modelling techniques for structural and geotechnical applications. It also points users back to EN 1990-1 Annex J, with “assessment” used in place of “design”.

The document is written as a draft for enquiry, so it is structured for review and comment rather than as a final consolidated standard text.
