Concrete construction: Carpenter, supported by Genie telescoping personnel lift, turns to fit slotted piece of cut lumber to horizontal rebars that penetrate formwork to give continuity to the retaining wall reinforcing. (Note the rebar penetrating the bulkhead below the blue platform. Bulkhead forms a short term construction joint in the concrete, until the next section of concrete is placed to the left.
