Engineered residential 13D fire sprinkler system

I am wanting engineered plans showing flow calculations, friction loss, pipe layout and sprinkler locations for a residential 13D fire sprinkler system. The house is 640 sq ft which includes a 20ft x 20ft lower level with a 12ft x 20 loft. I am familiar with code and will provide locations and number of sprinklers and schematics of the home which were created in SweetHome3D. Thank you
