The form for a concrete footing (10) is a mold for receiving concrete for footings on construction projects. The form has a housing (12), and a plurality of horizontal support members (16) that extend across the hollow interior of the housing. The form may be manufactured from plastic, cardboard, concrete or other materials. Vertical tubes (14) extend from the top and bottom and are hollow to allow for in situ soil sampling after the footing has been set in the excavation.
