From Ohio R.C. section 4733.22…
“No person shall practice, or offer to practice, the profession of engineering or the profession of surveying without being registered or exempted in accordance with this chapter, or present or attempt to use as the person's own the registration, the certificate of authorization, or the seal of another, or give any false or forged evidence of any kind to the state board of registration for professional engineers and surveyors or to any member thereof in obtaining registration or a certificate of authorization, or falsely impersonate any other registrant or holder of a certificate of authorization of like or different name, or attempt to use an expired, suspended, or revoked registration or certificate of authorization, or otherwise violate this chapter.”
From Ohio A.C. section 4733-35-07 (A)…
“The engineer or surveyor shall not sign and/or seal professional work for which he or she does not have personal professional knowledge and direct supervisory control and responsibility.”
Plan stamping is demonstrated when a Professional Engineer or Professional Surveyor places his or her registration seal on any drawings, designs, plats, descriptions and/or specifications that he or she did not author or for which he or she did not have personal professional knowledge and direct supervisory control and responsibility.
Personal professional knowledge is best demonstrated when a Professional Engineer or Professional Surveyor has been personally retained by an owner, registered design professional or a design/build contractor and is personally aware of a project's scope, needs, parameters, limitations and special requirements. It is preferred that the professional engineer or professional surveyor contract directly with the owner for all professional services to be rendered and then subcontract services such as drafting as needed.
Direct supervisory control and responsibility is best demonstrated when a Professional Engineer or Professional Surveyor has direct professional knowledge and is the actual author or has been in responsible charge of a design or project from its very inception to its completion.
In some cases it may be necessary for unregistered individuals, such as technicians or drafters, to assist the Professional Engineer or Professional Surveyor; however, the Professional Engineer or Professional Surveyor must maintain responsible charge of the project and total control of all design decisions in order to be in compliance with the Board’s laws and rules.
