Structural Eurocode systematic reviews

Adoption of Structural Eurocodes in the UK Building Regulations, and by the Highways Agency and Network Rail, means that the basis for structural and geotechnical design within the UK has now shifted from withdrawn British Standards to European Standards.   Publication of the Eurocodes started in 2002 and was completed in 2006, with full implementation by CEN members in 2010.

The process of reviewing the Eurocodes, with the aim of producing a limited amount of improvement, has started and the list of reviews is given below.  The CEN systematic review process provides all interested parties with an opportunity to comment on the current provisions for the express purpose of identifying where, and in what form, modifications are most needed.   The European technical committee CEN/TC 250 Structural Eurocodes recognises the importance of stability for users of the Eurocodes, so revised standards will not be published prior to 2020.

BSI, through its national mirror committee B/525 Building and Civil Engineering Structures, which I chair, invites responses to the following six review questions:

1. Do any clauses require editorial or technical correction?
2. Which clauses would benefit from improvements in clarity?
3. Where should the scope of the EN be extended?
4. Where could the EN be shortened?
5. Are there any clauses whose application leads to uneconomic construction?
6. Are there any clauses whose application necessitates excessive design effort? 

Responses, which may be either individual or collective, need to be sent to the B/525 secretary Keely Andrews, email bsi.construction@bsigroup.com no later than the 11th November 2015.  Comments should be accompanied with specific proposals for changes to address any issue raised, and supporting justification where relevant, using the generic comment template attached. The full set of UK contributions will be collated and reviewed within the respective BSI mirror committees, prior to submission to CEN/TC 250.

This is your opportunity to influence the Eurocode 'Evolution' process, by identifying areas in particular where the Eurocodes most need improvement in terms of coverage, clarity, economy etc.   The UK has, thus far, had  substantial influence on the Structural Eurocodes and is very well placed for this to continue since the current chairman of CEN/TC 250 which has the overall responsibility for the Evolution is Steve Denton of Parsons Brinckerhoff.  

For this to happen, we need representative and authoritative input from the Structural and Geotechnical Engineering communities.  This is your chance to influence the shape of the next generation of Structural Eurocodes; please use it.
