Questions from the floor

摘要

John Scholey of Jacobs asked for examples of what extending the design life to 200 years actually meant. He questioned whether designers actually understood what extending the design life meant. Bergmeister explained that based on the Eurocodes which assume 100 years, the safety factors have been increased by approximately 10 per cent, the concrete cover has been increased, and some additional monitoring has been incorporated. Also, additional maintenance and inspection intervals are being incorporated.
