This seems to be over your head so I suggest you talk to one of the senior EE's you work with to help you with this.

Senior EEs? They dont know. They say they are not electrician. Ofcourse they are mostly mechanical. Does anyone know the answer?

I think the appropriate question is "do you know how to read". Several knowledgeable folks have answered your question.
IF the 1600 amp switch is the service disconnect as the drawing indicates, grounding on the load side is determined by 250.122 "equipment grounding conductors" Per 250.24 no "grounding" should be accomplished on the load side of the serivce using the grounded conductor. Meter bases with isolated neutrals are available and should be used in this situation.
