Basic Requirements for Construction Works

Construction works as a whole and in their separate parts must be fit for their intended use, taking into account in particular the health and safety of persons involved throughout the life cycle of the works. Subject to normal maintenance, construction works must satisfy the following seven basic requirements for construction works for an economically reasonable working life.
  1. Mechanical resistance and stability
  2. Safety in case of fire
  3. Hygiene, health and the environment
  4. Safety and accessibility in use
  5. Protection against noise
  6. Energy economy and heat retention
  7. Sustainable use of natural resources

CEN Process Period

After receiving the final draft, CEN/MC organises the formal vote and the ratification, leading to the date of availability of the approved European Standard. This process requires about 8 months, depending on editing, translation (translation of the EN Eurocode Parts to the other two official languages of CEN) and finalisation of the document prior to making it available to CEN members for publication. []

Coexistence Period

During the coexistence period, which starts at the end of the National Calibration period, the EN Eurocode Part can be used, just as the former national system (codes and provisions) can also be used. The coexistence period of an EN Eurocode Package will last up to a maximum time of three years after the national publication of the last Part of a Package. At the end of the coexistence period of a Package, the NSBs shall withdraw all conflicting national Standards, and the Member States shall make sure that all the Parts of the related Package can be used without ambiguity on their territories by adapting their National Provisions as necessary. Thus all conflicting National Standards in a package should be withdrawn a maximum of 5 years after DAV of the last available Standard in the package. []

Component hEN or ETA

hEN or ETA for a prefabricated structural component or a kit consisting of structural components, such as prefabricated concrete components, prefabricated stairs or timber frame building kits, with properties determined by calculation applying methods which are used also for structural design of works. []

Construction Product

Any product or kit which is produced and placed on the market for incorporation in a permanent manner in construction works or parts thereof and the performance of which has an effect on the performance of the construction works with respect to the basic requirements for construction works.

Construction Works

Building and Civil Engineering Works.

Essential characteristics

Those characteristics of the construction product which relate to the basic requirements for construction works

Examination Period

After the final draft prepared by the Project Team is sent to the subcommittee for progressing to the vote, a period should be allowed for examination of the content of the EN Eurocode Part, by both competent authorities and Sub-committee members. After taking into account any comments generated from this examination, the Sub-committee approves the document to go to formal vote and sends it to CEN/MC (CEN stage 49).A maximum period for the examination, revision in the sub-committee and final approval to go to formal vote is 6 months. []

European Standard

European Standards have the following characteristics:

  • The Standards are drafted by one of three European Standard Organisations.
  • The work is based on consensus.
  • Standards are adopted after a public inquiry with the national votes based on corresponding weighting features. Standards remain voluntary but their transposition into national Standards and the withdrawal of diverging national Standards is mandatory according to the internal rules of the European Standards Organisations.

European Technical Assessment

Documented assessment of the performance of a construction product, in relation to its essential characteristics, in accordance with the respective European Assessment Document

European Assessment Document

A document adopted by the organisation of TABs for the purposes of issuing European Technical Assessments

Framework Programme

The Framework Programme is the European Union's main instrument for funding research and development. The FP is proposed by the European Commission and adopted by Council and the European Parliament following a co-decision procedure. FPs have been implemented since 1984 and cover a period of five years with the last year of one FP and the first year of the following FP overlapping. []

Further Development

Further updating and supplements according to pressures from market (new materials, products or methods) for innovative solutions and progress of scientific knowledge (e.g. need to avoid disasters in the area of public safety). []


Further step of development of EN Eurocodes to transfer the Nationally Determined Parameters (NDPs) into a system with one or several classes so that design values calculatively determined with these classes may be referred to in harmonised product specifications. []

Harmonised Standard

A standard adopted by one of the European standardisation bodies listed in Annex I to Directive 98/34/EC, on the basis of a request issued by the Commission, in accordance with Article 6 of that Directive


Act of Member States to bring EN Eurocodes into force in the framework of their National Provisions. []

Intended use

The intended use of the construction product as defined in the applicable harmonised technical specification


a construction product placed on the market by a single manufacturer as a set of at least two separate components that need to be put together to be incorporated in the construction works

Life cycle

the consecutive and interlinked stages of a construction product’s life, from raw material acquisition or generation from natural resources to final disposal


Actions for updating, revision and completion of EN Eurocodes. []


Standardisation mandates are the mechanism by which the Commission requests the European Standards Organisations to develop and adopt European Standards in support of European policies and legislation.

Material hEN or ETA

The hEN or ETA for a material or constituent product, with properties which enter into structural calculations of works or otherwise relate to their mechanical resistance and stability and/or fire resistance, including aspects of durability and serviceability, such as concrete, reinforcing steel for concrete, certain structural steel products, fire protection materials. []

National Annex

Annex to an EN Eurocode Part containing the NDPs to be used for the structural design of buildings and other civil engineering works in a Member State. []

National Calibration Period

A period of two years after DAV is the maximum time allowed to fix the Nationally Determined Parameters. The SCC could, however, examine requests, for exceptions. At the end of this period, the national version of an EN Eurocode Part will be published, with the National Annex, which will include the Nationally Determined Parameters. At the end of this 2-year period, the Member States should have adapted their National Provisions so that this EN Eurocode Part can be used on their territory. The National Annex shall be sent to the EC services for information. During this period, the Member States shall inform the Commission about the result of the tests undertaken using this EN Eurocode Part. []

National Provisions

National laws, regulations and administrative provisions, imposed by all levels of public authorities, or private bodies acting as a public undertaking or as a public body on the basis of a monopoly position.

Nationally Determined Parameter

A National choice left open in an EN Eurocode about values (where symbols are given in the EN Eurocodes), classes or alternative procedures permitted within the EN Eurocodes. []

Non-Contradictory Complementary Information

The National Annexes to the Eurocodes Parts may contain references to non-contradictory complementary information to assist the user to apply the Eurocode.

Notified Body

Third-party body designated by the Notifying Authority of an EU Member State to perform the Declaration of Conformity of products. The list of New Approach Notified and Designated Organisations is available at NANDO.


Load-bearing construction i.e. organised assembly of connected parts designed to provide mechanical resistance and stability to the works.

Structural Material

Material or constituent product with properties which enter into structural calculations or otherwise relate to the mechanical resistance and stability of works and parts thereof, and/or to their fire resistance, including aspects of durability and serviceability.
