Subchapter 17. Licensee’s Seal
245:15-17-1. Licensee's seal
- (a) Every person licensed to practice engineering or surveying may obtain a seal with which to identify all final engineering and surveying papers or documents, including drawings, specifications, plans, reports, surveys, plats, land descriptions, design information, construction documents, calculations, addenda, change orders, field orders and other documents of service involving the practice of engineering or surveying issued by the licensee for use in the State of Oklahoma whenever presented to a client or any public agency to certify that the work thereon was done by the licensee or under the direct control and personal supervision of the licensee.
- (b) The seal required shall be of a type which will make an image on the surface of original documents and duplications of original documents. The use of a rubber stamp or electronic digitization which produces an accurate and legible image of the seal is permissible.
- (c) The seal of the licensee shall consist of two (2) concentric circles. The inner circle shall have inscribed the licensee's name and license number, which shall correspond to the name and license number shown on the Certificate of Licensure. The area between the two (2) circles shall be inscribed with the word "Oklahoma" at the bottom reading counter-clockwise and the words "Licensed Professional Engineer" or "Licensed Professional Surveyor" at the top reading clockwise. The seals commercially designated as 1 7/8" seal, with an inner circle of 1 1/8" diameter and an outer circle of 1 ¾" diameter, or the 1 5/8" seal, with an inner circle of 1 1/16" diameter and an outer circle of 1 9/16" diameter, are acceptable, as shown in Appendix A of this Chapter. Reproduction of the original documents with the required seal may produce a different seal size provided the seal remains completely legible.
- (d) A licensee who practices in other than their full legal name shall register the name customarily used in professional practice with the Board together with a copy of their signature for such customarily used name. The seal may be inscribed with the registered, customarily used name, and the signature affixed across or adjacent to the seal shall be the name inscribed on the seal. A seal and signature affixed in a registered, customarily used name shall have the same force and effect as the seal and signature affixed in a licensee's full legal name.
- (e) Existing seals containing the words "Registered Professional Engineer", Registered Professional Land Surveyor", "Registered Land Surveyor", and “Professional Land Surveyor” may continue to be used.
- (f) Licensed "Professional Structural Engineers" may obtain an additional seal and use the word words "Professional Structural Engineer" in lieu of "Licensed Professional Engineer" to use when sealing structural engineering projects, whether or not the work requires the seal of a Professional Structural Engineer. Work defined as a "significant structure" shall be sealed with a "Professional Structural Engineer" seal, and/or signed with the designation "P.E., S.E." following the signature.
- (g) An Engineer Intern or Surveyor Intern shall not have a seal.
