What is a bridge? - Industry Insights:Bridge Engineering with Ian Firth Pt 1 Transcription

• 00:00 - 00:30 you a bridge is much more than just a means to cross an obstacle getting over a river or railway it's much more about a sense of place it's about creating an environment that wasn't there before in this short set of videos I hope to show you how the bridge engineer must deal with more than merely the
• 00:30 - 01:00 functional aspects of crossing the obstacle whatever it is and look as well at the environmental social and cultural issues that make the difference between just a bridge and an elegant landmark that people love my bridge design projects are varied from the very small like the bridge of aspiration in Covent Garden between the opera house and the ballet school to the very large Massena bridge for example between Italy and Sicily the mainland of Italy to Sicily three point three kilometers in a
• 01:00 - 01:30 single span I've been fortunate enough to work with some of the world's leading bridge architects and have won a number of competitions with them such as the Porsche man in Lyon France the Stonecutters bridge in Hong Kong and the little aluminium footbridge the lock Meadow Bridge in Maidstone Kent but my work has not just been about British designers the early part of my career was spent almost entirely at looking at existing structures assessing them understanding how they worked learning from the mistakes that previous
• 01:30 - 02:00 designers may have made where maintenance for example had not been properly considered and those lessons have been very instrumental in my design work later in my career bridges connect people they link communities and a bridge is going to create an opportunity for people to get to market or to school or the hospital which wasn't there before and the engineer needs to understand how those
• 02:00 - 02:30 factors will influence the design a bridge across the river is very often a catalyst for a new city think of London Paris New York places where the bridge was the pure the first thing that people did in order to develop that town so no surprise then that the bridge is significant for the culture the society the people who live there and the engineer must understand that
• 02:30 - 03:00 bridges are designed by structural engineers but of course we very often work with architects landscape designers urban planners and so on and the most successful designs come from an integrated approach between those disciplines the engineers task is to deal with the technological issues construction material materials and so on in addition to the environmental the social cultural understanding those things and of course today we're asked
• 03:00 - 03:30 to span further and to build more quickly and always of course with elegance and with aesthetic appeal in mind so an engineer needs to enjoy a challenge inevitably British design involves teamwork sometimes with several organizations involved but I find that it works best when there is an overseeing mind there's somebody who has the complete picture even down to some of the important
• 03:30 - 04:00 little details so although he or she can't do everything and will be supported by engineers and others doing analysis and calculations and drawings and all those things he or she will need to be sufficiently alongside and across all of those issues to be able to know how the whole package fits together sometimes you may divide the project the bridge into components so the obvious one being the superstructure and the sub structure and we sometimes worked where
• 04:00 - 04:30 one company is doing foundation design and the other company is doing the superstructure the bits you see and that that works well you could also divide it another way it's depending on the size of the bridge and nature of the bridge a great bridge needs to do more than just span the gap it needs a character all of its own it's relatively easy to to make it work to have enough material to make it strong and stiff and so on what people really
• 04:30 - 05:00 notice indeed what people really demand is much more they want the appearance to be good they want something which touches their soul and and you need to feel that sense of delight and that's going to make a difference between an ordinary and a special page what does it look like from a distance how does it feel close-up is it a place that you want to say to your girlfriend let's meet at that bridge and you know how does the top of the tower look against the night sky these are the things that really make a difference for me some of
• 05:00 - 05:30 the great bridges include my hours huginn a toll bridge and suits and high up in the hills it's the most beautiful elegant white concrete arch technically brilliant but also just so beautiful and so so wonderful in a setting the Meo viaduct in south of france michel virlogeux the engineer obviously engine also with architecture by Foster's again a beautiful response an extraordinary
• 05:30 - 06:00 setting with a very deep valley and this sort of rhythm of the seven pylons just so beautifully down a gentle curve fantastic bridge a great favorite of so many in Denmark the great belt East bridge a suspension bridge over open water so a very different kind of context but where the sculptural form of the towers the Anchorage's the whole whole composition just works so well the
• 06:00 - 06:30 architect diffing and vitalink all are incident in particular working with the engineers koey on that one and here in London completely different scale the small and delightful Sackler crossing by John porcelain Kew Gardens where the engineering is really nothing but it's such a beautiful piece of sculpture really very elegant a beautiful composition on so s-shape in clan so these for me epitomize some of the things that we try to to do when we design ridges in part 2
• 06:30 - 07:00 we're going to look at more about how we do it but in this first part we've understood that a bridge needs to be much more than just a crossing we've we've looked at how a bridge designer needs to learn from history and from others by by studying other cases before they can really be effective as a designer we also need to understand the cultural the social environmental issues and that's a really important part of being able to design a really good
• 07:00 - 07:30 bridge we've looked at the importance of teamwork and how although is in my view an engineer must lead the design of a bridge there are others architects landscape designers lighting designers and so on who will be involved from time to time and also it's really important to understand that bridge to zone is much more than just applying the codes of practice we've got to look beyond that and take your pencil a blank sheet of paper and we're going to look at that next time
• 07:30 - 08:00 you
