The top surface of the form is smooth, and a series of hand grip indentations and fork lift fork receiving recess indentations are provided about the vertical perimeter apron to allow for easy handling and manipulation of the forms, whether by hand or by fork-lift, during placement, removal, shipping, storage, transport, or the like.
