I wonder if you have the experience for doing this? Electrical designs are as varied as the days of the year. Some engineers allow for "value engineering", no plans for expansion.

If you have the one line the rest should be easy. See how big the panels, mcc's, and service are and then look up the sizes in one of the manufactures catalogs. Then add in working clearances and your almost there.

You do not design switchgear. You place standard parts into the pre-established sections that the manufacture has gotten approved for the use. Number and size of the sections depends on the voltage and the overcurrent device installed. The challenge is; with out knowing some technical information about the location any specific suggestions are mute.
