It's been two weeks since the groundbreaking. I can't imagine what they could possibly be waiting for at this point. If they want to finish in two years they better hurry the hell up.
I would expect to see heavy machinery next week. There is only a cement truck on site right now but I cannot verify if this is for FMC.
They could basically start now. Only have to remove some fencing and they're good to go.
If there's nothing by next week I'm getting a shovel and starting to dig myself!
