UK GEOTECHNICS has until 11 August to comment on the draft of the national annex to Eurocode 7: Part 1 - Geotechnical design.
The national annex dictates how EC7 Part 1 will be used in the UK.
It lays out which values of partial factors and any other parameters should be used in design, such as the compulsory use of Design Approach 1 in the Eurocode.
After the comment period BSI will make any amendments before publishing the national annex.
Eurocode BS EN 1997-1 (Geotechnical design - general principles) was published in December 2004. Its companion, prEN 1997-2 (Geotechnical design - Ground investigation and testing) has received a positive vote from EU members and is due to be published by BSI by the end of 2006.
Once both BS EN 1997-1 and BS EN 1997-2 and their national annexes are published, EC7 will be able to be used in the UK. The withdrawal of the con. icting national standards is expected by March 2010.
The BSI committee responsible for EC7 development said it had made great efforts to ensure advice in current geotechnical British standards would remain available to help engineers apply the Eurocodes.
In some instances, for example the design of reinforced earth and . l materials, the Eurocode does not provide a design process and BS 8006 will be retained; but many other British standards will not.
