A licensee may sign and seal plans, specifications, drawings, reports, or other documents that are required to be signed and sealed pursuant to the Business Occupations and Professions Article, §14-4A-02, Annotated Code of Maryland, only if the following requirements are met: The licensee is competent in the subject matter of those documents by virtue of education or experience, or both; and The licensee either: Personally prepared the documents, or Approved the documents.

For purposes of §A(2)(b) of this regulation, the term “approved” means that the licensee satisfied the following criteria: Had technical knowledge and responsible control over the content of technical submissions during their preparation; and Performed substantive review and had authority to make revisions with regard to the preparation of submissions described in this regulation. A licensee may complete, correct, revise, or add to the work performed by another licensee when engaged to do so by a client, if the following requirements are met: The client furnishes the documentation of the work submitted to the client by the first licensee; The first licensee, if still engaged in a business of providing engineering services, is notified in writing by the second licensee of the engagement referred to in this section immediately upon acceptance of the engagement; and The second licensee signs, seals, and is responsible for the completions, corrections, revisions, or additions that the second licensee made.
