The inside of the forms, with the metal straps that hold the inside and outside forms together visible. The conduit and boxes for electrical are in place, held tightly against the inside form by wires. At the bottom is a block of white polystyrene foam which will be excavated after the forms are removed to allow wiring to be fed into the conduit and up to the plug, switch, junction box and, at the top, another box. The open conduit will be connected to another conduit up on the ceiling with a box for a fan or light. During the pour the concrete will flow around all the boxes. Each box is wrapped in duct tape to seal it against the concrete and allow easy access after removal of the forms by simply slicing the tape out of the way.
