Sometimes you just need a little room to work ....

I think I have figured out what the poles and frames are all about. CASE put in the permanent foundation work, but now Walsh needs some temporary work space ... so they build their own.

Sept 22



Sept 28

Adjusting it ... one end would be lifted slightly and a small crane would tug or push it a bit.




Sept 29

Taking shape


Patching the home-made double beam that has obviously seen use before.


We don't need WD-40 !
The cross members are also re-purposed beams
note how they are welded to the double beams that sit on the capstans on the pounded round pipes.


Finally satisfied with the positioning - welding it to the capstan.


Almost done

Getting down to that good Chicago clay





Follow the yellow plank road ....

Word is that this is not extra work space, but an additional road (technically a bridge) for use during construction.

The view from 150 N River - on a rainy Open House Chicago

The river is up.


Now you can call it a bridge

Getting ready for the next ring of whalers.


Nov 9

I'm pretty sure there is a strain gauge under this, and a matching one on the other side. The pressure from the clay beyond the sheet piles must be immense.

Old Pilings - well preserved in the anaerobic clay

Nov 13

Waiting to be installed - the next set of braces - The square frames are being used to brace the existing garage wall.

Nov 13



Not the chains used in lifting it out of the pit.


Strain gauges - must be strain gauges.

The gravel fill from the hole - protects the rebar that is sticking up out of the piling. The top of the rebar will be at or near the top of the foundation mat.


The pink loops are the rebar sticking out of the piling.

Sleeper in the works ? (note the foundation poking up at the back).


Another foundation pile being un-graveled.


Dec 15

Old wooden pilings - the anaerobic clay preserves the wood very well.


The red wires go to strain gauges on the crossbeams.

Found where they buried the foundation piers.


A pair of spread footing piers poke their tentacled heads above the clay. Ready for the long sleep(er).




One of the rock-socketed piers. I believe the blue wires are for O-Cell testing.

Note the "bricks" put under the bottom rebar so it is positioned correctly at the bottom of the pour
