Hello Everyone,I am new to the industry and working on my first project involving a basic design which includes relocation of some existing electrical loads to a new switchboard and removing the existing switchboard. I was wondering if anyone could share some of their drawings (single line and floor plan) which I could use a reference. I would really appreciate the help. I am confused on how to create a existing oneline showing the demo stuff and create as-built drawings. Thank you

A simple Internet search should turn up examples of a single line wiring diagram.  Another option would be to consult a book such as "Architectural Drafting & Design" by Jefferis & Madsen.
