Part E Robust Details New Code Proposals • Robust Details Limited will publish (and update) a Table of constructions that meet the Code criteria • Builders using Robust Details will NOT have to conduct additional PCT to claim Code credits • PCT is an alternative still available for builders who choose to follow this route to compliance (but there are no ‘rewards’ for extra testing) robustdetail

Robust Details so far…. ODPM Regulatory Impact Assessment: 16 November 2002 Paragraph 51: “BRE estimate that, in new dwellings, as many as 40% of new separating floors and up to 25% of new separating walls may fail to meet the current standards. The changes for new dwellings, particularly the pre-completion testing regime, are intended both to improve standards and to reduce the failure rate to below 5% over 10 years. ” robustdetail

Robust Details Regulatory Change Where next? robustdetail

Robust Details Regulatory Change Drivers for Change: • Cyclical Review • Precedent Disasters • Government Policy robustdetail

Robust Details Regulatory Change Drivers for Change: Part E • Cyclical Review • Consultation in January 2001 • Implementation in July 2004 (for PCT and RDL) robustdetail

Robust Details Regulatory Change Drivers for Change: Part L • Government Policy • Consultation in July 2004 • Implementation in April 2006 robustdetail

Robust Details Regulatory Change • 19 months to develop • Less industry involvement • Significant pressure to change • 3 -and-a-half years to develop • Close industry involvement • Pressure to change less intense robustdetail

Robust Details Regulatory Change Performance monitoring National database The ‘pattern book’ approach…. robustdetail

Part E Robust Details The trouble is, once pattern books get onto building sites, actual performance reduces alarmingly Not in the case of Robust Details. . . …RDL’s patterns are actually drawn up from field tests on real building sites robustdetail
