After excavation of the southern side of the site, the hill was covered with tyvek or similar material to combat erosion and keep the hill intact while the retaining wall is formed at placed. Below are pictures of the southern side.

| Workers placing formwork. Most, if not all the caisson holes have been drilled and prepped. Notice the hill covered with tyvek as discussed earlier. Column rebar is being spliced into the caisson piers (top of picture). |

| Rain, mud, and other debris will get into the drilled hole for the piers. Pictured above are workers mucking out the hole with a shovel and air hose. Notice the safety caps so the workers won't get impaled. |
 |
| Slab has been poured for the southernmost retaining wall. Columns have been spliced/tied into the caissons and safety caps have been placed on all rebar. |
