I will do electrical and lighting designs with autocad drawings

Yes of course, you need to provide only the floor plans. I will take care of the rest and submit the Load calculation, Lighting Design, Socket Outlet layout, Distribution Board details and also the Single Line Diagrams too.

If it is availble with you it will be easier for me, If AutoCAD file is not the available with you, I can workout with the existing layout of yours.

Of course, I will do the heat load calculations for your building design.
