The information of the cost increase appears less than complete:
1] what happened from the initial numbers of $15.5 and $28.5 million?
2] previous posts and public conversation appear to focus on steel and China etc. While these are of course relevant, my guess is structural engineering and other issues have been equally important (as is mentioned but not quantified in the introduction (quote: "The increased costs were primarily associated with line item costs for structural steel, drilled shafts, site excavation and structural concrete – the four items that are the most critical structurally, and the most difficult to construct.").Can we see a breakdown from the beginning of all costs and the changes?

And when/if the project proceeds,what protection will have against further 'change orders'? Will we have a fixed price contract on most if not all line items (including "drilled shafts, site excavation and structural concrete")? My experience is that most construction over-runs occur with foundations, ie, below the ground. My fear is that we will continue to bear this risk, even after the 'final contract' is signed.
