I don't think it's concrete. These buildings have a fair amount of sub grade work for the pumps and recirculation between the oxidation ponds. "Ground and infrastructure" could refer to only grading and civil even at 100%. If we turn on the infrared wave bands it looks this way. Doesn't look like concrete to me.
But it also doesn't really matter, IMO. We know they're experiencing a cash crunch until the funding is finalized And we know they can crank these out pretty fast when everything is lined up. Once they have the funding in hand you're going to see the vertical construction go pretty quick. Right now call it whatever you like, the point is that they aren't building, otherwise you'd already see building structure and maybe even a roof.
