In the following images below you can see the multiple retaining walls that are located across the hillside to allow the ease of access and the necessary soil retainment for the installation of pile caps.  Once the pile caps are formed and poured, they will be backfilled, and the site will have an consistent grade down the hillside.  The workers below are prepping top of caissons prior to installing rebar reinforcement for the pile cap in that location.
