Scope

I.S. EN 13670 gives common requirements for execution (construction) of concrete structures.
This standard is applicable to in-situ works and construction with prefabricated elements.

It is also applicable to permanent as well as temporary concrete structures.

A separate project specification is required which contains all the specific requirements relevant to the particular structure.

Use

This standard has three functions:

  • Transfer of requirements set during design to the constructor/ builder (i.e. a link between design and execution)
  • Provide a set of standardized technical requirements for the execution, when ordering a concrete structure
  • Serve as a checklist for the designer to ensure that he provides the constructor with all relevant technical information for the execution of the structure (see Annex A)

I.S. EN 13670 provides guidance on:

  • Execution management and quality management
  • Concreting operations
  • Formwork and falsework
  • Reinforcement
  • Surface finishes
  • Execution with precast concrete elements
  • Geometrical tolerances

I.S. EN 13670 refers to, and is reliant on other I.S EN standards, particularly those for materials (e.g. I.S. EN 206 Concrete, I.S. EN 10080 Reinforcing steel etc., along with their test standards), and the design standards I.S EN 1990, I.S. EN 1991 & I.S. EN 1992.

The National Structural Concrete Specification (UK document) may provide additional useful guidance. It provides a BS EN 13670-compliant specification for use in structural concrete building construction designed to the Eurocodes.

In essence it contains three parts :

  1. Standard Specification
  2. Project Specification
  3. NSCS Guidance

Note that it is based on UK Standards, which vary from Irish equivalents, particularly in National Annexes ; thus the tables in the NSCS should not be used in any Project Specification in Ireland and should be replaced with those from I.S. EN 206 + NA.

Note: Use the latest version of the standard, along with the accompanying National Annex, including any Addenda or Corrigenda updates for either, issued by NSAI. Irish Standards are available at www.NSAI.ie/standards.
