The grand stand foundation is on sime drilled cocrete piling. A pile cap was placed on top of the drilled piling. These were put in BEFORE the job cam was put up. The only thing we have seen is the placement of the grade beams and plumbing and other mechcanical installations. The footings you see are placed on top of the pile caps. The load path is structural steel connected to the footings by way of anchor bolts that are in the footings. The footings transfer load to the pile caps then to the drilled concrete piling.
The steel, anchor bolts, footings pile caps and piles all line up vertically.
I am sure there are footings placed closer to the field but they are too far away and we cant see them from this camera shot. I would suspect that the grand stands will be supported by a steel structure that spans from the footings we see in the camera to footings we can't see at the edge of the field. The slab they will eventually place is not structural it is a floor to walk on.
The camera they have set up has a wide angle lens on it and it makes things appear further away than they are and distorted.
