A concrete form panel system includes a basic form panel of expanded polystyrene material having at least one slot formed in the top surface along its length, to divide the panel top surface into piers. A series of top hats are provided for selective attachment to the piers to increase the depth of the slots between piers, and thereby increase the depth of a joist formed by hardened concrete poured into the slot. Transverse slots may also be formed by separating top hats along their lengths. The transverse slots create transverse bracing between T-joists in a concrete deck. The form panels and top hats may also be used to create separate structural joists with attachment lifts, to permit connection of the joists to a subsequently constructed floor or deck system.
