Special Session Delegate Discussion Professor Bryan Karney University of Toronto, Canada, will invite interactive dialogue with

delegates to explore whether we have matured enough to allow us to be a little more quantitative about uncertainly. We largely pretend we live in a mechanical world of

deterministic outcomes that are bounded by worst cases – have we reached the limit of what such an approach can achieve particularly in very complex systems? Should we try to map

the territory of unknowns? Or should such considerations continue to be ignored?

Delegate participation We are sure all Delegates will have views on this vital topic – please prepare your thoughts on this, even if they might be controversial (nothing will be “on the record”!), especially if you have case experience to share which illustrates your point of view”.

Open forum - Spectacular failures and transient related accidents

Professor Sam Martin, Georgia Tech, and Dr M Hanif Chaudhry, University of

South Carolina; will chair this exciting final day session. By sharing experiences we hope delegates might gain a better understanding of practical problems and

realise the complexity of designing against and predicting surge. We need delegates to describe real problems that have arisen where designs or

constructions do not behave in the way expected and to go beyond redesigns and discuss those instances where there was a spectacular failure.

There will be no written papers for these sessions but the Committee asks

delegates to contribute to these discussions.

Delegate participation requested – Please notify Ally Davies at confx2@bhrgroup.co.uk if you have a case you would like to share.

13:30 Conference close with lunch – Novotel Restaurant

Where you see the laptop sign we will be loading presentations for the next day.
