The barges that were used for 150.
It appears that they are pulling out some of the braces - to put caissons in those spots ?
Demonstrating why he wears a face shield.

nobody messes with the bridges - easier to cut out part of your wall.
Slant capable - apparently putting in whatever the cables tie off to.
Preparing runs

Stubby rig for low clearance - put in the H-Piles under the edge of Wacker
Working on the wall

Tightening and filling
Tied off (hose clipped off)
The land side - the angled brace is tied off to something the slant drill put in, the sheet piles have been welded to the brace.

A view soon gone

Now it's started. The chains are holding up a rebar cage that is suspended in concrete.

A deft hand adjusting the yard stick
Some serious re-bar - these appear to say V 1 S = 75 If I am reading this right it is from V, a #1 sized rod (the biggest ?), Steel, and is grade 75.
Slurry pipes. For when a thick muddy slurry is used in the shaft to keep the walls apart, and you don't want your concrete diluted as it sinks to the bottom. The pipe is assembled, run to the bottom of the shaft, and the concrete (heavier than muddy water) displaces the water up the shaft.

This view of the Sears tower will be lost
July 31
Taking the long coupled rebar off the barge - one at a time - and lowering them into the shaft with the already hefty cage in it.

Another case of hitting slime - something odd is under our clay ;-)
Still not sure where these are used, but they seem to be building slightly different ones for each big pier.

Deep foundation work is completed - starting on the mat (no basement here)
Spud Barge
Putting in the spuds
At first I thought it said TONKA - wish it did
[TONKA made metal construction toys back in the 60's/70's, all this shade of yellow]
Marking where the foundation piers lay waiting.
