CAN I HAVE MY BUILDING ON CONCRETE BLOCK INSTEAD OF THE WOOD BLOCKS PROVIDED?

Yes! We only require that you provide the blocks. The rule of thumb for figuring blocks is one block for every 4′ to 6′ of skid length on the flat ground. A typical 10×16 is blocked at 6 to 8 points, one block on each end of the skid and one or two blocks in the middle of each skid.
