Abstract: A method and apparatus for forming concrete wall panels used in tilt-up wall buildings comprising a grooved, truncated triangle shaped speed set double chamfer fixedly attached to the building floor, a side wall form adapted to nest within a groove formed in the speed set double chamfer, means attaching the side wall form to the double chamfer, and a second speed set double chamfer inverted over and fixedly attached to the wall form, the wall form nesting interior to the inverted groove of the speed set double chamfer. The concrete wall panel to be formed is poured into a form having the perimeter comprising the invention. When the concrete has set, the upper speed set double chamfer and side wall form is removed and the wall panel tilted up and emplaced.
