Concept Sketch
Our group discussed that due the size of our bridge, from an engineering and feasibility point of view, a beam bridge would be most suitable. However, beam bridges are not ‘fun’ bridges and we wanted to do something that took a step up from that. Jenny showed us some great images of a helical bridge and we decided that it would be good for us to do something similar.
Once we agreed on the bridge, we discussed possible materials we could use. Once we made a list of these materials, I formulated a concept sketch so we could all get a ‘feel’ for how this will work when it comes to the modeling process.
The only amendment since sketching this drawing would be the notable 1:10 gradient which we now agree will be 1:20 or 1:15 with intermediate platforms.
