Re: Signing mylars or vellums

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You're exactly correct.  Florida's 'rules' of the Board require that all documents submitted for public record be signed and dated by the engineer, and then 'sealed' with a raised impression.  The rules don't address any other documents.

The intent is that the 'sealing' of the blueprints which are submitted for building permits represents a certification by the engineer that the information contained therein complies with all applicable codes and standards.
