3. PREPARE THE FOUNDATION
Having scribed the diameter of your foundation, proceed by digging the footing of the foundation. This
consists of a large circular trench dug just inside the foundation line. (Refer to foundation details for necessary
information.) Once the footing has been dug, you are ready to build the forms. It is important that your form
be rigid enough to hold its shape against the poured concrete. Also, the foundation must be flat. Sloped floors
cannot be used in drying bins. A carpenter’s level placed on top of your 2 x 4 will enable you to set the top
of the forms to match the top of the center stake. Check the form work with a transit to ensure a uniform
elevation for the entire foundation.
