European foreword
This document (prEN 13670:2025) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by SN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13670:2009.
a) Annex H has been removed and replaced with Clause 0.2 “Provisions valid in the place of use for
EN 13670”;
b) The main text has been updated on FRP, CFRP and SFRC;
c) Annex F has been updated on SFRC;
d) New Annex H on “Strengthening of Existing Concrete Structures with FRP“ has been added;
e) General updates to align with revised EN 1992-1-1:2023;
f) General updates to align with the forthcoming prEN 206-1;
Because of the close connection between design rules and rules for execution, CEN/TC 104/SC 2 has
developed this document in liaison with CEN/TC 250/SC 2, and CEN TC 229.
Introduction
0.1 Introduction to EN 13670
(1) This document applies to the execution of concrete structures to achieve the intended level of
safety and serviceability during its service life, as given by EN 1990, Eurocode – Basis of structural
design, EN 1992, Eurocode 2 – Design of concrete structures and EN 1994, Eurocode 4 – Design of
composite steel and concrete structures, with the Nationally Determined Parameters (NDPs) applicable
in the place of use.
(2) This document has three functions:
a) to transfer the requirements set during design to the constructor i.e. to be a link between design
and execution;
b) to give a set of standardized technical requirements for the execution when ordering a concrete
structure;
c) to serve as a check list to ensure that the designer provides the constructor with all relevant
technical information for the execution of the structure (see Annex A).
(3) In order to achieve these objectives, the design should result in a set of documents and drawings
giving all information required for the execution of the construction work in accordance with the plans.
This set of documents is, in this document, referred to as the “execution specification”. This document
leaves a number of items open to be decided in the execution specification.
(4) In areas where national provisions apply, these should be referred to in the execution specification.
(5) It is recognized in this document that areas such as detailed requirements for competence of
personnel, and details related to the Quality Management are within the competence of the Member
States.
(6) If the national CEN member publishes a National Annex to this document, it may refer to national
standards approved and published by the CEN member or national provisions, which supplement this
document. Alternatively, the supplementing rules can be given directly in the National Annex.
(7) A detailed overview of the system of European Standards related to concrete construction works is
shown in Figure 1.
Figure 1 — System of European Standards as basis for design, execution and materials selection
for concrete construction works (only main modules)
(8) Supplementing requirements are given in some member states when using, for example:
a) lightweight aggregate concrete;
b) other materials (e.g. fibres, ultra-high performance concrete) or constituent materials;
c) special technologies/innovative designs.
0.2 Provisions valid in the place of use for EN 13670
(1) National choice is allowed in this document where explicitly stated that provisions valid in the place
of use may be given.
(2) The national standard implementing EN 13670 can have a National Annex or complementary
standard containing all national choices to be used in the relevant country.
