I've found a few previous discussions that touched on this, but nothing specific to my question, so here goes:
For design professionals and code officials, does your state have any specific requirements pertaining to the use of digital seals and/or signatures on construction documents (plans)?
My state does. Buried in the agency regulations for architects and for professional engineers is the requirement for them to have and use a seal. Under that, the regulations were revised about 20 years ago to allow for the use of digital seals/signatures rather than live ("wet') seals and signatures, BUT both the architects' regulations and the engineers' regulations then include specific criteria for what constitutes a digital seal. The important factor is that it has to be verifiable through a third-party authentication service, and it has to be such that if the underlying document is edited in any way after having been signed and sealed, either a flag is placed advising that the document was revised after it was signed, OR the digital seal/signature has to disappear.
What we still see in probably 90% of applications (or more) is just a scan of the design professional's seal and signature, pasted onto the title block. With paper prints, this is obvious when the signature is exactly the same on every sheet in the set, and falls in exactly the same relationship to the seal. With PDF digital drawings, it's even easier to spot -- when a document containing a proper digital signature is opened in most PDF readers (Adobe Acrobat, Adobe Reader, Fox-It, even FreePDF) there's a notice announcing that the document was digitally signed by [____] on [_date_] at [_time_] and that the digital signature is valid.
For us, it's in state law, so the same applies to every municipality throughout the state. What's the situation in other states? Does your code and underlying legislation allow digital seals and signatures? If so, do your laws or regulations require third-party authentication, or can design professionals just make a scan of their seal and signature and paste it onto their title block?
