This is an interesting picture. It looks like they will have to excavate at least 30 - 40 feet at this location since there is supposed to underground parking. Are they are driving piles to see how deep they can excavate before hitting rock?
Here is a sketch from this document -

On the Market Street side (highest ground elevation) it appears as though they will have to excavate at least 70 feet deep, assuming the Exhibition Hall height is 30 feet and there will be three levels of underground parking (plus at least 10 feet of ground above the Exhibition Hall).
