This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2010, and conflicting national standards shall be withdrawn at the latest by June 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes ENV 13670-1:2000. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s). Because of the close connection between design rules and rules for execution, CEN/TC 104/SC 2 has developed this standard in liaison with CEN/TC 250/SC 2, and CEN TC 229 According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 13670:2009 (E) 6 Introduction This European Standard 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. This European Standard 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 for the designer to ensure that he provides the constructor with all relevant technical information for the execution of the structure (see Annex A). In order to achieve these objectives, the design shall result in a set of documents and drawings giving all information required for the execution of the work in accordance with the plans. This set of documents is, in this European Standard, referred to as the "execution specification". This standard leaves a number of items open to be decided in the execution specification.
In areas where national provisions shall apply these should be referred to in the execution specification. It is recognised in this European Standard 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.
If the national CEN member publishes a National Annex to this standard, it may refer to national standards approved and published by the CEN member or national provisions, which supplement this standard, alternatively the supplementing rules can be given directly in the National Annex
A detailed overview of the system of European Standards related to concrete works is shown in Figure 1.

Foreword
This document (FprEN 13670:2009) has been prepared by Technical Committee CEN/TC 104 “Concrete and
related products”, the secretariat of which is held by DIN.
This document is currently submitted to the Unique Acceptance Procedure.
This document will supersede ENV 13670-1:2000.
Because of the close connection between design rules and rules for execution, CEN/TC 104/SC 2 has
developed this standard in liaison with CEN/TC 250/SC 2, and CEN TC 229.

Introduction
This European Standard 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 – Basis of structural design, EN 1992 – Design
of concrete structures and EN 1994 Design of composite steel and concrete structures, with the Nationally
Determined Parameters (NDPs) applicable in the place of use.
This European Standard 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 for the designer to ensure that he provides the constructor with all relevant
technical information for the execution of the structure (see Annex A).
In order to achieve these objectives, the design shall result in a set of documents and drawings giving all
information required for the execution of the work in accordance with the plans. This set of documents is, in
this European Standard, referred to as the "execution specification". The standard leaves a number of items
open to be decided in the execution specification.
In areas where national provisions shall apply these should be referred to in the execution specification.
It is recognised in this European Standard 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.
If the national CEN member publishes a National Annex to this Standard, it may refer to national standards
approved and published by the CEN member or national provisions, which supplement this standard,
alternatively the supplementing rules can be given directly in the National Annex
A detailed overview of the system of European Standards related to concrete works is shown in Figure 1.

1 Scope
(1) This European Standard gives common requirements for execution of concrete structures, it applies to
both in-situ works and construction using prefabricated concrete elements.
(2) This standard expects the execution specification to state all the specific requirements relevant to the
particular structure.
(3) This standard is applicable to permanent as well as temporary concrete structures.
(4) Additional or different requirements should be considered and, if required, given in the execution
specification when using:
a) lightweight aggregate concrete;
b) other materials (e.g. fibres) or constituent materials;
c) special technologies/innovative designs.
(5) This standard does not apply to concrete members used only as equipment or construction aids for the
execution.
(6) This standard does not cover the specification, production and conformity of concrete.
(7) This standard is not applicable to the production of precast concrete elements made in accordance with
product standards.
(8) This standard does not cover safety and health aspects of execution, or third party safety requirements.
(9) This standard does not cover contractual issues or responsibilities for the identified actions.

3 Definitions
For the purposes of this standard, the following definitions apply:
3.1
backpropping
propping installed at levels below the slab that supports the falsework in order to distribute the load to suitable
support
3.2
chair for reinforcement
device used to secure the position between reinforcement layers e.g. supporting top reinforcement in a slab
3.3
construction works
everything that is constructed or results from construction operations (see EN 1990)
NOTE The term covers both building and civil engineering works. It refers to the complete construction comprising
both structural and non-structural components
3.4
constructor
the organization executing the works
3.5
erection specification
documents covering all drawings, technical data and requirements required for the safe erection of precast
elements
3.6
execution
all activities carried out for the physical completion of the work, i.e. procurement, scaffolding, formwork,
reinforcing, concreting, curing, erection of precast elements etc., and the inspection and documentation
thereof
3.7
execution class
classified set of requirements specified for the execution of the works as a whole or an individual component
3.8
execution specification
documents covering all drawings, technical data and requirements necessary for the execution of a particular
project.
NOTE The execution specification is not one document but signifies the total sum of documents required for the
execution of the work as provided by the designer to the constructor. It includes the project specification prepared to
supplement and qualify the requirements of this European Standard, as well as referring to the national provisions relevant
in the place of use.
3.9
falsework
temporary support for a part of a structure while it is not self-supporting and for associated service load
3.10
formwork
a structure, permanent or temporary, for containing poured concrete, moulding it to the required dimensions
and supporting it until it is able to support itself.
NOTE Formwork consists of the face contact material and the bearers directly supporting the face contact material
