I've got to get this off my chest. This final bridge product is, in no way what was portrayed on the original design. I realize this happens often, but it's got to stop. I've got a degree in Architecture from Iowa State (and a Computer Science degree). I really enjoyed the 'proposed' bridge, but by comparison not so overjoyed on this design. That's just my opinion and I'm sure others will have contrasting ones as well. My point is that oftentimes the final product is a consequence of unexpected costs. And, there should be no excuse not to have a very detailed and accurate financial proposal for the original bridge. Project costs should be taught as a fundamental course in the Architecture curriculum and with today's technology should be very accurate (sans mother nature) to the actual construction costs. All that said, this bridge is still better than nothing.
You do realize that often what's depicted in "original concepts" are in reality unfeasible to build, or at least in may cases impractical because the type of engineering and/or construction it would take to make the original concept to life would be far too expensive.
I think it's more like you need to understand that an original concept is a vision or a dream - not what is what's going to be built in reality.
