European foreword
This document (prEN 1990-1:2024) has been prepared by Technical Committee CEN/TC 250 “Structural
Eurocodes”, the secretariat of which is held by BSI. CEN/TC 250 is responsible for all Structural
Eurocodes and has been assigned responsibility for structural and geotechnical design matters by CEN.
This document is an amendment to EN 1990:2023 and is currently submitted to the Enquiry.
The following main changes to EN 1990:2023 is included in the amendment:
— inclusion of application rules for:
— towers, masts and chimneys (Clause A.3);
— silos and tanks (Clause A.4);
— structures supporting cranes or other machines (Clause A.5);
— coastal structures (Clause A.6);
— inclusion of combination factors for new categories for imposed loads.
The first generation of EN Eurocodes was published between 2002 and 2007. This document forms part
of the second generation of the Eurocodes, which have been prepared under Mandate M/515 issued to
CEN by the European Commission and the European Free Trade Association.
The Eurocodes have been drafted to be used in conjunction with relevant execution, material, product
and test standards, and to identify requirements for execution, materials, products and testing that are
relied upon by the Eurocodes.
The Eurocodes recognise the responsibility of each Member State and have safeguarded their right to
determine values related to regulatory safety matters at national level through the use of National An-
nexes.

(3) The design rules provided in the Eurocodes assume that:
— execution will be carried out by personnel having appropriate skill and experience;
— adequate control and supervision will be provided during design, assessment and execution of the
works, whether in factories, plants, or on site;
— construction materials and products for new structures or new structural members will be used in
accordance with the Eurocodes, in the relevant product and execution standards, and project
specifications;
— the structure will be adequately maintained;
— the structure will be used in accordance with the assumptions.
NOTE Guidance on management measures to satisfy the assumptions for design, assessment and verification
and execution is given in Annex B.”
