My group has chosen the South Quay Swinging Bridge design, located in Canary Wharf, London to produce a 1;50 scale model section from. We will have Monday, Tuesday and Wednesday across eight weeks to realise this.
The first decision we reached was on the support structure, deciding it will need to be made of solid chemiwood to provide enough strength to suspend the walkway from. This section would also be rather difficult to cast as we have had limited experience with this medium and any mistakes would clearly show up, especially if we made it clear like how we inteneded most of the model to be. Our initial idea was that we could make the whole moving section of the bridge to this scale, with the walkway fading to reveal clear acrylic at the ends, with the focal point of the support mast in colour.
Looking at existing models, we decided we would use clear acrylic rod for the cables and laser cut the boards and rails from clear acrylic. Much of the design plans are readily available to us in different programs and at different scales so we will need to convert these appropriately into Adobe Illustrator before we can produce samples of the bridge on the laser cutter.
