COPENHAGEN’S ‘KISSING’ BRIDGE WEALTH CREATION The bridge’s sliding spans are cantilevering, steel box girders. Their undersides follow a smooth wave-like profile in elevation to provide the greatest structural depth at the support where the bending moment is largest. The structural depth then tapers to only 600 millimetres at the cantilever tip at midspan, where the two girders meet and interlock The middle spans on the Inner Harbour Bridge in Copenhagen slide apart to allow large boats to pass through the harbour. The spans then slide back together again and have earned the bridge the nickname Kyssebroen (the Kissing Bridge) © Jasper Carlberg Aside from COWI, the team the opening sections in a sliding focus more on functionality comprised architects Studio manner and create a functional than design.

These include some highly complex and challenging projects, and range from very long suspension and cable stayed bridges, such as the Messina and Stonecutters Bridges, to much smaller but unique and unusual structures, such as the Bridge of Aspiration, Lockmeadow Footbridge and Taplow Bridge for example. He has designed over 80 bridges (although not all have been built) and has developed a reputation as one of the world's leading bridge designers and strongest advocates for achieving quality and elegance in bridges and infrastructure. -

The Role of Independent Design Checking in Major Projects
IABSE Symposium, Weimar 2007 Adding confidence and reducing risk - the role of independent design checking in major projects Ian FIRTH Ian Firth graduated from the Partner University of Bristol and joined Flint & Neill in 1979 becoming Flint & Neill a Partner in 1990. He obtained London, UK a Master’s Degree in Structural Steel Design from London’s Imperial College in 1982, and has recently been elected a Fellow of the Royal Academy of Engineering. He is mostly engaged in bridge projects and is known for his work both as designer and as checker. Summary Responsible clients and designers commission an independent check of their designs, particularly when the scale or complexity of the project requires it. This paper explores the culture of independent checking that exists in the UK, especially in connection with major bridges, and examines the benefits to be gained from such an approach. The cost of adding confidence and reducing risk through such a check is very small compared to the enormous benefits gained, particularly on major projects. The author draws on his own experience as well as published information to illustrate the importance of establishing such a culture of independent checking everywhere. Keywords: Independent design check. Design verification. Independent certification. Category 3 checking. Design review. Risk reduction. 1. Introduction Following the collapse of the steel box girders bridges in Milford Haven (Fig.1) and Melbourne in 1970 and the very significant work carried out by the Merrison Committee of Inquiry in preparing new design and workmanship rules for such structures, there has been a culture of independent design checking for major bridges in the UK.
