Southernmost formwork and concrete placement of the southernmost retaining wall is ongoing.

| Slab on grade with #4 rebar. Notice the horizontal keyholes for between the vertical rebar to help the newly poured retaining wall bond better to the slab. Also, horizontal dowels are placed at every construction joint on the slab-on-grade. These are usually spaced every 10-15 meters. |

| Picture of a crane (appears to be 50-ton) that is owned and operated by Commercial Steel Erection (CSE) based out of Roanoke, VA. CSE is a subcontractor hired to rig and erect the steel structures on site (http://www.cseonline.net/index.php). Many cranes have been used on site, each for different uses, including a larger crawler crane that is capable of lifting larger structural steel members such as the caissons. This crane is being used to erect and place the vertical members of the southernmost retaining wall. |
