ABSTRACT:
A method and assembly (20) to form a cast concrete panel (21). The assembly (20) has end beams between which tendons (23) can pass. The beams need to be able to support tensioning of the tendons. Transversely extending form members (25) cooperate with form members (27) to enclose a space to receive concrete to form the panel (21). The tendons (23) pass through the space.
