PURPOSE: This rule describes the format for personal seal of an architect, a professional engineer, a professional land surveyor, and a landscape architect.

1. (1) Each person licensed as an architect, professional engineer, professional land surveyor or landscape architect (not including interns or individuals “in-training”) shall, at his/her own expense, secure a seal one and threequarters inches (1 3/4”) in diameter of the following design: the seal shall consist of two concentric circles between which shall appear in roman capital letters, the words, “State of Missouri” on the upper part of the seal and either “Architect,” or “Professional Engineer,” or “Professional Land Surveyor” or “Landscape Architect,” as the case may be, on the lower part, and within the inner circle shall appear the name of the licensee, together with his/her license number preceded by the roman capital letter(s) A for Architect, PE for Professional Engineer, PLS for Professional Land Surveyor or LA for Landscape Architect.

   1. (A) The seal of an architect licensed prior to January 1, 2002 may display “Registered Architect” on the lower part and within the inner circle shall appear the name of the licensee, together with his/her license number preceded by the roman capital letter A.
   2. (B) The seal of a professional engineer licensed prior to January 1, 2002 may display “Registered Professional Engineer” on the lower part and within the inner circle shall appear the name of the licensee, together with his/her license number preceded by the roman capital letter E.
   3. (C) The seal of a professional land surveyor licensed prior to January 1, 2002 may display “Registered Land Surveyor” on the lower part and within the inner circle shall appear the name of the licensee, together with his/her license number preceded by the roman capital letters LS.
2. (2) The seal may be in the form of an embossing seal, a rubber stamp, or a computer-generated image, identical in size, design and content with the provisions of section (1) above.

3. (3) In addition to the personal seal, the licensee shall also affix his/her signature and place the date when the document was originally sealed, at the minimum, to the original of each sheet in a set of plans, drawings, specifications, estimates, reports and other documents which were prepared by the licensee or under his/her immediate personal supervision. The term “signature,” as used herein shall mean a handwritten identification containing the name of the person who applied it; or for electronic or digital documents shall mean an electronic authentication process attached to or logically associated with the document. The digital signature must be unique to, and under the sole control of the person using it; it must also be capable of verification and be linked to a document in such manner that the digital signature is invalidated if any data on the document is altered.

   1. (A) Documents that are without an electronic signature or authentication process that are transmitted electronically shall have the seal removed and the following inserted in its place: “This media should not be considered a certified document.”
   2. (B) When revisions are made, the licensee who made the revisions or under whose immediate personal supervision the revisions 20 CSR 2030-3

were made shall sign, seal and date each sheet and provide an explanation of the revisions.

1. (C) In lieu of signing, sealing and dating each page, the licensee(s) may sign, seal and date the title page, an index page, or a seals page on bound multiple page documents not considered to be drawings, providing that the signed page clearly identifies all of the other pages comprising the bound volume. Provided further that any of the other pages which were prepared by, or under the immediate personal supervision of another licensee be signed, sealed and dated as provided for, by the other licensee. Any additions, deletions or other revision shall not be made unless signed, sealed and dated by the licensee who made the revisions or under whose immediate personal supervision the revisions were made.

1. (4) Plans, specifications, estimates, plats, reports, surveys, and other documents or instruments shall be signed, sealed and dated unless clearly designated preliminary or incomplete. If the plan is not completed, the phrase, “Preliminary, not for construction, recording purposes or implementation” or similar language or phrase shall be placed in an obvious location so that it is readily found, easily read and not obscured by other markings. It shall be a disclaimer and notice to others that the plans are not complete.
2. (5) In the instance of one (1) licensee performing design for other licensees to incorporate into his/her documents, each licensee shall seal, date and sign those documents, using the appropriate disclaimer for clarification of each licensee’s responsibility.
3. (6) The signing and sealing of plans, specifications, estimates, reports and other documents or instruments not prepared by the licensee or under his/her immediate personal supervision is prohibited.
4. (7) This rule supercedes any conflicting rules.
