The proposed design will almost certainly change but I wouldn't call that change 'value engineering'. I doubt the architects have spent significant time and expense in determining exactly what materials would be able to achieve that design, it's a fanciful drawing currently.
IF the proposal goes forward, then the architects will do a re-design of something close that can actually be built. You can argue that this is 'value engineering' but at this stage I think any changes from the initial design would be as a result of actual engineering.
