Abstract: An apparatus and method for the rapid perimeter screed bulkhead forming of concrete tilt-up wall panels are provided. The apparatus includes a unitary formboard support, a formboard, and a fastener. The unitary formboard support includes a base, which includes a fastener passageway through the base, and two upright walls connected to the base, which form an open channel. The unitary formboard support can be attached to a casting surface or concrete floor by the fastener which passes through the fastener passageway and secures the unitary formboard support. The bottom end of the formboard is fit within the open channel of the unitary formboard support and held in position by the upright walls.
