Electronic Signature

As a practice, we "electronically" stamp our drawings with the following process. I have asked a number of other professionals and so far very little has been said. I'm considering talking to the board but thought I would stop here first. My question to you, in your opinion do you feel we meet the requirements of our State? (Washington Administrative Code provide below )
1) we have an 8.5x11 sheet with a number of blank seals printed on it.
2) to "seal" a document, we identify the documents being sealed, sign, date, hand write the expiration date, and finally include our job number.
3) we then scan this page to PDF where it is cut and pasted into the model space of our Autocad file. On each page a viewport displays the signed stamp.
4) we keep a copy of all of our signed seals for future verification.
5) as a policy we never release a "working" Autocad drawing, instead we wblock the information requested, never including a signed stamp. If a revision takes place after the release of drawings, the drawing file is saved with a new revision date in the file name. The old stamp would then be replaced for the next issuance of drawings.
6) our final document is usually a PDF which is either printed and/or provided on disk.


Your thoughts please.


WAC Chapter 196-23-070
Signature.
The terms "signature or signed," as used in chapter 18.43 RCW and/or Title 196 WAC, shall mean the following:

(1) A handwritten identification that represents the act of putting one's name on a document to attest to its validity. The handwritten identification must be:
(a) Original and written by hand;
(b) Permanently affixed to the document(s) being certified;
(c) Applied to the document by the identified licensee[;][.]
(d) Placed directly over the seal/stamp of the licensee.

(2) A digital identification that is an electronic authentication process attached to or logically associated with an electronic document. The digital identification must be:
(a) Unique to the licensee using it;
(b) Capable of independent verification;
(c) Under the exclusive control of the licensee using it;
(d) Linked to a document in such a manner that the digital identification is invalidated if any data in the document is changed.

We use a similar system except that we only keep the final pdf. We do not keep autocad files with stamps on them. An Autocad file can be changed, whereas, the pdf can be easily protected.
 
I keep my seal in paperspace, along with the titleblock, and wblock model space when I need to send a CAD file. That way, the seal is not in the CAD file. Since most states publish license numbers on websites for verification, anyone can create a my seal, so I am less concerned about the seal itself falling into the wrong hands. Regardless, the seal itself needs a signature to be a certfication of the document. So when I send preliminary drawings to clients for review, my seal will appear on hte PDF. In the 9 states I am licensed in (1 is technically a district), only Michigan specifically does not allow electronic seals, and I think West Virginia recently allows electronic seals.

In Ohio, where I use that license the most, I also digitally sign the PDF, just above the seal, with the date I am "signing" the PDF. When you receive the PDF, it will saw the document was digitially signed by me when you click on the signature (Adobe Acrobat). If you change the document, the signature becomes disassocaited with the document.

I have been able to e-mail my clients the PDF's and they in turn submit them to blueprinters for copying. Makes my life easier and allows my client to "save" reimbursable costs. I have even e-mail revisions directly to a building department to avoid a correction letter.

In Ohio, this is certainly okay, and in most states, they should be adopting similar language since, at the federal level, digital signatures are became legal when Clinton signed the Millinium Act back in 2000 or something.

PLEASE check with your local board. I am registered in 42 states and I don't THINK any two are exactly the same.

Some allow it - some don't!!! And their requirements are all over the board!!
 
your a fool to think PDF drawings can not be protected. As Mike said,ask your State Board.
 
Folks, read the OP, he has listed his State requirements & indicated that he plans on talking to them, he's asked for your thoughts!
 
I hand stamp everything. It gets scanned and emailed, but there is no PDF of my stamp and signature waiting to be posted on an autocadd drawing. In this hury up enviornment, hand stamping allows me to reveiw it before it gets stamped. I worry most about people trying to expedite work for clients and the review cycle breaking down. A lot of people, including clients have been greatly upset at needing an extra day to review the drawings because I did not have a chance to look at it as soon as it was done, however I was happy that I could review it when I could focus on it. Having the stamp in my desk drawer gives me that control.
 
DRC1, I believe your method would be the most Iron Clad with one step in the hand stamp world and one in the electronic world. For me, I don't yet have a large format scanner and would add a day to an already busy schedule should I send it out to the printer for scanning.
"A digital identification... logically associated with an electronic document." It seems to leave a bit of room for implementation.
You do raise an interesting point with regards to review and having a quiet moment alone to reflect one last time before issuing documents. I have often wondered what others use as a review process, but that is for another post.

I appreciate the input so far, I would welcome others...
 
We debated a long time about buying a large format scanner/coppier/printer. We finally did it. It has really paid for itself, probably one of the most useful pieces of office equipment.
 
WE use our seal as a reference file, which we place in the issue directory upon our consent of the design for transmittal. Once the drafters are done printing the transmittals we delete our seal from the issue directory and therefore the electronic drawings are seal free.

In your case it seems like you don't meet part (d) i.e. your stamp and seal are part of the drawings and modifications can be made under the same seal.

Remember you are personally responsible for your seals and should protect the seal from falling in any hand, internal or external.
 
zazmat, you make a good point with regards to part (d), furthermore, I can't imagine what purpose is served by leaving it in the cad file.

What do you mean by "issue directory". Is this something you create in your directory tree or a function I am not aware of?
Thank you for your post...
