Concrete/residential construction: Cast in place concrete is being placed into Arxx hollow polystyrene insulating plastic wall forms using plywood side forms at top of sloped Arxx wall forms. From right to left, workers are (1) placing concrete on right side of forms through elephant trunk extending down from the end of the hydraulic boom of a Schwing truck mounted concrete pump; (2) removing top form panels from top of concrete/forms on left side of wall; (3) filling in and troweling top of cast concrete, and (4) extending vibrator into concrete placed prior to that in the left side of the wall. At lower center of photo is window opening with shore and bottom forms to support concrete placed above window until the concrete attains sufficient strength to support itself and loads imposed above the window.
