PDF Edits

I have previously wet stamped drawings and scanned them in as PDFs. I can't find a rule that addresses this case specifically (looking at Tennessee rules).

My question is; Can edits to the PDF be made including revision number and date with those edits, while leaving my original stamp with hand signature and date across it on the PDF? Or should the revisions be made (in PDF or CAD), then reprinted and signed and sealed again with new date, then scanned back in as PDFs?

RE: PDF Edits

My practice has always been to re-stamp and re-date a drawing when any change was made. Yes, this can be tedious for a small change but usually we'll just submit only the sheets that changed.

The only drawings or documents I stamp in .pdf I use the Adobe "sign" function to attach a facsimile of my stamp. That way any change to the .pdf invalidates the stamp.

RE: PDF Edits

These were scanned into PDF already stamped and revised in Bluebeam. I just decided to wet stamp them again.

RE: PDF Edits

Considering your PE stamp also included the date of the stamp, any additional edits should have a later date. Therefore, the drawing should be stamped again with the date for the later edits.
