  6. 6. Client’s General Specification <ul><li>FORMATION OF CGS </li></ul><ul><li>First stage: </li></ul><ul><li>- general Civil Engineering practices, recognised design and construction rules, guidance from authoritative organisations (e.g. BRE, CIRIA) </li></ul><ul><li>Second stage, based on: </li></ul><ul><li>- Client’s experiences of previous works (construction techniques, lessons learned from existing structures); </li></ul><ul><li>- specific requirements for power station structures (cooling tower, dams, intake tunnels, containment) </li></ul>Not Protectively Marked - New Nuclear Opportunities © 13 September 2010 EDF Energy plc.

  7. 7. <ul><li>CONTENT </li></ul>Client’s General Specification Not Protectively Marked - New Nuclear Opportunities © 13 September 2010 EDF Energy plc. All rights Reserved.
  8. 8. Adaptation to UK Context <ul><li>Language translation and technical adaptation to UK practices </li></ul><ul><li>Four broad levels of adaptation: </li></ul>1 . Direct (or near) replacement of NF EN with equivalent BS EN (~80%) e.g. replacement of NF EN 1008 « mixing water for concrete » with BS EN 1008 2. Replacement of French accreditation bodies with UK equivalent (~15%) e.g. NF BPE (production facility for ready mix concrete) replaced by QSRMC, or AFCAB by CARES 3. French only standards (no direct equivalent in UK) (~5%) e.g. FD P 18-011 - Definition and classification of aggressive environments for concrete mix design covering pure water , for which there is currently no authoritative guidance in UK 4. Client’s procedures (materials tests) (~1%) e.g. EDF procedure for concrete porosity Not Protectively Marked - New Nuclear Opportunities © 13 September 2010 EDF Energy plc. All rights Reserved.
