Are the tubes caissons for the drill? Maybe they’ll start the excavation for the building but just redirect any soil that needs treatment to whatever treatment it needs. Dig it up just once.
If this is correct, most likely they’ll start by installing piles, probably massive vertical I-beams, around the outside using the caisson drill then dig down, installing wooden shoring as they go.
Can't say I know what a caisson is, but the spiral drill piece fit almost perfectly inside the tubing. Definitely looked like pile-driving equipment
An aside: oh my god, I've just realized THAT'S where pile driving comes from!?
