THE TELFORD Medal, the highest Institution of Civil Engineers accolade for a paper, has this year gone to Melanie Batten and Professor William Powrie for their 'Measurement and analysis of temporary prop loads at Canary Wharf underground station'.
The two were presented with their award by ICE president Joe Dwyer at last month's presidential dinner.
Temporary prop loads in large excavations are often overestimated in design. After measurement and analysis of retaining walls at Canary Wharf underground station, Batten and Powrie found that realistic temporary prop loads can be calculated using conventional soil mechanics principles. Their findings were published in July 2000.
The project was funded by the Engineering & Physical Sciences Research Council with help from Carillion, BachySoletanche, Arup, Skanska Cementation Foundations and construction industry research body CIRIA.
The winners of the George Stephenson Medal were also announced at the dinner. Jim Hall, Mark Lee and Ian Meadowcroft took the prize with their paper 'Risk based benefit assessment of coastal cliff protection'.
The paper demonstrates that a risk-based approach to evaluating the economic benefits of coastal cliff protection is superior to current practice because of the uncertainty inherent in cliff recession predictions.
