Abstract
A false formwork system (40) includes a plurality of sideforms (17) which are able to be interconnected to define a perimeter of an opening in a panel to be cast. A support structure (24) is carried by the sideforms (17) for supporting components (26) used to mould a false skim coat overlying the opening when the panel is cast. An opening demarcation portion (21) is carried by each of at least some of the sideforms (17). Each opening demarcation portion (21) defines a zone of weakness to demarcate the skim coat of the cast panel from a remainder of the panel and to facilitate removal of the skim coat from the remainder of the panel by breakage along the zone of weakness.

1-15. (canceled)
A method of casting a concrete panel, the method including erecting a plurality of sideforms on a base to define an outer periphery of a panel to be cast;
- erecting false formwork within the sideforms to define an opening in the panel to be cast;
- demarcating at least a portion of a periphery of the opening;
- mounting infill in the false formwork so that the infill lies at a level lower than a surface of the panel to be cast;
- pouring concrete into the sideforms so that the concrete overlies the infill to define a false skim coat over the opening;
- and allowing the concrete to set to provide an uninterrupted upper surface of the panel.
