Basics of Beginning of the Top Secret Bunker Project and Removing Soils

Step 2 Start Strong

The test shaft was to be centered between two columns and the concrete block filled wall of the bottom level and although I wouldn't want to just pull out the two columns to see if it worked, the way the beams are run the floor above it would still stand although I imagine it might develop a bounce if you hopped around in the dining room so once again it appeared a reasonably safe place to start experimenting and since I like thing stout and on resting on a good foundation, and since when working top down the Foundation is on top but still first I began with a foot thick perimeter wall connecting both piers to the main wall and full of very heavy scrap steel including a tightly fitted I Beam between the bases of the two columns and rebar bent and wrapped around the columns and then left protruding past the pour to tie into the next section of wall and also having done it before when I built my dock, knew I could jet a piece of pipe down a pretty far way if I had enough water so I used a flexible pool skimmer hose connected to an 1 1/4 inch water line and shot down 4 ten foot sections of 3 inch sewer and drain pipe down so they would come up inside the first pour, dropped a piece of rebar in them and filled them almost to the top with a sand and cement mix. I hit clay at about 6 or 7 feet so I ended up with some ten foot posts resting in the seam of clay and then tied the rebar into the walls which are tied into the columns and concrete wall.

And thus I had my Footer to lock everything in place.
