Just idle pile driver attachments, the one attached to the machine in this photo of yours is a helical drill bit while the others standing in the ground (looking like columns) are hammers for the steel beams (piles) driven into the earth.Anyone know what the columns are for?
I’m not familiar with the site plan for Aurora. In that specific location I don’t know what they’re piling for, my best guess is prep for digging out the pedestrian tunnel.
