Has been debated in these environs and just not done. Too many problems for sealing... unless you (and I mean the engineer sealing the documents) have full time supervision of the project, and the client is not likely prepared to pay for this... and for liability reasons, I don't want to waste my time.
As built drawings should be provided by the contractor... and the information can be added to the project drawings without seal and, generally, without company titlebox...
