Include a reinforced concrete washout slab poured independently of the load bearing piers, a minimum four inches [101.6 millimeters] thick, poured underneath the entire length and width of the scale; ande.

Be constructed on soil that has a uniform natural or engineered soil bearing of at least one thousand five hundred pounds per square foot [71.82 kilopascals];c. Be supported on a monolithic, steel-reinforced, concrete slab a minimum of twelve inches [304.8 millimeters] thick poured on top of a base of uniform, compacted, permeable aggregate, at least twenty-four inches [609.6 millimeters] deep;d. Be installed to manufacturer's specifications to support the device, prevent shifting, and provide protection from the environment; ande. Be installed with the top surface of the foundation slab above the surrounding grade level so that water will flow away from the foundation and away from the permeable aggregate base that supports the foundation.N.D.
