Solving Sub-Floor Technical

For my design to work, the I-Beam columns will have to be extremely well supported and fixed at the base, as there can be no bracing anywhere else due to the multiple moving parts. I have decided to have each column bolted to an auger pile. these are driven into the ground, then each module is attached.

The sub-floor framing is a typical housing sub-floor, and is as follows. The columns are joined by square hollow tubing bearers. these are welded and plate bolted to the column I-Beams. Timber joists are then bolted onto the bearers, at 600mm centres. Finally the floor is nailed or screwed to the joists. A lightweight timber shell is constructed, and attached to the outside, so as to hide all of the construction underneath.
