Georgia Title 43, Section 43.15.2-11...
(11) "Professional engineering" means the practice of the art and sciences, known as engineering, by which mechanical properties of matter are made useful to man in structures and machines and shall include any professional service, such as consultation, investigation, evaluation, planning, designing, or responsible supervision of construction or operation, in connection with any public or private utilities, structures, buildings, machines, equipment,
processes, works, or projects, wherein the public welfare or the safeguarding of life, health, or property is concerned or involved, when such professional service requires the application of engineering principles and data and training in the application of mathematical and physical
sciences. A person shall be construed to practice or offer to practice professional engineering, within the meaning of this chapter who by verbal claim, sign, advertisement, letterhead, [highlight]card[/highlight], or in any other way represents or holds himself out as a professional engineer [highlight]or engineer[/highlight] or as able or qualified to perform engineering services or who does perform any of the services set out in this paragraph. Nothing contained in this chapter shall include the work ordinarily performed by persons who operate or maintain machinery or equipment.
The law is relatively clear that to hold yourself out to the public as an "engineer" implies professional engineering and requires licensing.
