After the engineers collected data from the measurements and identified trees for removal, Brian ordered hydrological tests to evaluate the subsoil. The drilling was in two places behind the north wall. This test was performed by employees of engineer Winslow Goins, Engineering Department Manager at ECS Carolinas, LLP, Wilmington, NC. After engineer Brian evaluates the data from the subsoil drilling he will finalize the entire engineering study.
The north wall after the trees have been removed. The machine in the distance is performing core drilling, establishing the depth of the water table. Notice the bow in the wall near the doorway of the storage room. The long passageway wall is where military walked west toward the target area.
