In professional engineering practice, which statement describes who signs the seal on drawings?

• A. Project owner signs.
• B. Architect signs as the sole endorsement.
• C. Licensed engineer signs as the seal on the drawings.
• D. No signature is required.

Answer: (C)

Signing the seal shows professional accountability: a licensed engineer is the one with the legal authority to certify that the drawings meet the applicable codes and standards and that the design has been prepared under their supervision. The project owner does not hold the required engineering license, and an architect’s signature covers architectural aspects rather than the engineering content. Without a licensed professional signer, the drawings lack the mandated professional certification. Therefore, the seal on engineering drawings is signed by a licensed engineer (with license number and date as applicable).
