Concrete retaining wall construction: Retaining wall in background is in four phases: (1) complete, just right of cneter, (2) formwork erection in center, (3) reinforcing erected just to left of center, and still unreinforced in far left. Three carpenters erect formwork using Genie telescoping mobile lifts. Carpenter form erection tool box is in left center, and carpenter form fabrication is right center foreground. Rebars protrude from footing in foreground, to provide continuity to concrete foundation wall to come. Right foreground shows foundation wall exterior formwork. Other equipment shown is rough terrain forklift to far left, backhoe in background to its right, air compressor in mid-left foreground, wheeled tractor in right background, hydraulic crane boom at top right, and large cable crane at top center.
