A rigid form member for use in tilt-up construction of a concrete panel is disclosed. The form member has a pair of upright walls (10, 11) connected by a number of internal ribs (16, 17), where each rib includes an aperture to allow a fastener (21) to pass through for fastening the form member to a surface. The walls extend to a height above the highest portion of the fastener so that fastener heads (22) do not protrude during construction of the panel. |
