They excavate the site first and dig a couple of holes on it. One of these holes is use to remove underground water. And then they put the continous retaining wall in remain two hole and pour concrete into. I think underground foundation is in process and we can not see from the surface.
(Continous retaining wall is about 50m deep....)
For information, I think we need to ask engineer....
