Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

(OP)
That was mouthful. So imagine this:

1) You digitally stamp some drawings in full compliance with all of the statues etc.

2) The building department insists on hard copies so your client prints out your drawings and turns 'em in.

Anybody experienced push back in terms of accepting the printed versions of the digitally stamped versions?

I would have thought that the printed set would have lost all of it's validity as a stamped document. However, I called the WA department of licensing and they said that it should be fine. I could hear a little hesitation in the guy's voice though.

Anybody have any personal experiences to to relay? Shipping drawings to WA form Canada is going to be a pain. That said, I don't want my client to be getting hassled at the desk.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

In Manitoba, Canada, this is done all the time. Either copies of an original stamped set or even a printed set that has "original stamped by" over the engineer's seal. I imagine that specific jurisdictions could have different preferences they enforce though.

Depends on the jurisdiction here Koot. I have seen it both ways.

Check with the local building official and see what they will accept.

A lot of jurisdictions require fresh inked stamps for the protection of your stamp. I have had mine stolen twice in the past and can relate.

Thanks for chiming in damorim. Same for Alberta. In fact, I've taking to stripping out the true digital signature because it causes issues with PDF manipulation and none of the authorities even seem to be aware of its presence in the first place. BC on the other hand gives me all kinds of grief. They're all set up for digi-stamping but it seems that many of the jurisdictions insist on wet seal. Annoying, especially when you've paid all the fees etc.

Ouch, I'd imagine having your stamp stolen/reused would be quite the headache...

Perhaps something similar to the State of ND requirements for electronic drawings will fit your situation:

Electronic reproductions of drawings, plan sheets, specifications, studies, reports, plats, maps,
and other engineering and surveying work product that are distributed to reviewing agencies,
owners, clients, contractors, suppliers, and others must either contain the electronic seal and
digital signature as required by this chapter, or have a digital signed and electronic sealed
statement from the registrant transmitting the same which shall read: "This document(s) was
originally issued and sealed by (name), Registration Number (number) on (date)".The
statement shall also include the statement that "The original documents are stored at
(location)",
or "The original documents have been destroyed and are no longer available",
whichever is applicable. Sets of plans or drawings must have this statement attached to every
sheet of the set. For specifications, reports, and studies, only the cover or introductory sheet
need include this statement.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

Florida does not allow this. Electronic signatures are valid only on the electronic file. Hard copies must be wet sealed to be valid. Again, that's Florida.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

The Structural Engineer's Association of Washington (SEAW) says that no wet seal or signature is required under State law. They acknowledge (like msquared said) that people at building departments have asked for it anyway.
Wet Sealing and Signing of Structural Submittals

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

That would suck if the bldg. departments required wet seals. I print off over 500 jobs per year and email all of them.
Most contractors want their stuff that day and my office is in the boonies.
Let's get realistic, though. Anyone can have a wet seal made to say anything. That does not guard against fraud.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

It all depends on jurisdiction. Some more remote counties require wet signed on one month and the next month they are fine with electronic stamping. It's really annoying.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

Anything other than hard copies with wet seals with dated signature over top the wet seals invites theft/fraud.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

Yup.

Thanks, everyone, for your help. I got in touch with the AHJ. This one's going to be a digital submission.

KootK:
My seal is generally applied as a block on layer 0, on layer S-Anno-Seal, for example. The drawings are plotted with this and the block removed and purged. I sign and date the plot, and this drawing is scanned to a pdf.

A couple of times (in emergency situations) had the *.pdf file eMailed to me and I've applied a 'rubber stamp' pdf seal, signature and date. This has been returned, plotted and scanned with the original pdf file and 'rubber stamp' seal signature and date deleted (sent only to trusted people).

Toronto no longer accepts paper drawings for permit applications. Electronic only.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

With the digital age, and ability to order anything off the internet, I have pretty much come to the conclusion that if someone really wants to steal my stamp, they are going to.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

I suppose from the limited perspective of preventing theft of seal, New Jersey is doing it right.

Speaking of, I made my own WA stamp digital image this morning. Surprisingly easy, even with curved text to mess with. I have a physical stamp that I could have scanned but I find that terribly inelegant. Hopefully I'm not violating any rules by doing my own digital doctoring. Frankly, I don't know how else to procure a digital image. I'm dying to show off my handiwork but that would be too much of a compromise to my cherished anonymity.

Nice art work - did you do this within Bluebeam Revu?

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

(OP)
Well, that is just the recommended image from Washington's web page. I shoulda made a dummy edit at the same time for anonymous sharing and evaluation. Too much work now. It was mostly Bluebeam. Also Word, Snipping Tool, and an online thing that's especially good at removing background pixels. I found that one of the keys to it is use dark grey text rather than pure black. I also go in and lighten/delete a few pixels around the edges of the text. Makes for an nice, well worn look.

I did make one serious error though. I put a lot of effort into a nice, background free signature a while back. It's built into all of my stamps now. Trouble is it's green pen. Not sure why I did that. Shoulda been blue for legality. You'd think that would be an easy edit but it hasn't been.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

I originally created my own digital stamps, and then realized I can just order one for less than the time it took me...like less than 1/4 of the cost of my time :)

There isn't any regulation on ordering a wet stamp or digital stamp. So in that regard, counterfeit is pretty much unstoppable. My signature is all over the place. A quick picture of my signature and a little "KootK" handiwork and you have a bonofide document. I really just kind of chuckle every time someone gets serious about protecting their stamp by only wet signing. It's the digital age, really can't prevent much of anything.

What now? Where do you get them from? Perhaps my googling skills are getting rusty in my old age.

I've been intentionally staying out of this debate so far but now I can't resist. I actually think that counterfeit stamping is less of a problem in the digital age. At least now I can easily go online and verify that Mike hasn't been dead for twenty years. And while nothing's un-hackable, I feel that true digital signing offers a fair bit of protection if only the AHJ's would actually make use of the functionality when they receive documents (my jurisdiction is useless this way).

I'd like to know more about this. Can you save me a little research and give me a quick overview?

Eh, maybe not so bad. 60 minutes my way. With shopping, credit card checkout, receiving the product, and adding my signature to the image, it probably woulda been at least 40 min anyhow, plus the $10 ($7,368 CAD).

KootK: you're slow. It takes me less than 10 minutes to go to the site, put my info in and then check out. Plus, the digital copy gives me instant gratification...which is super COOL! ;)

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

I guess my low-tech (for 2017) method of stamping a piece of paper, signing it, scanning it & making a TIFF, & inserting that into a drawing or onto a document is just "too yesterday". It took me as long to type this as it takes me to do what I described, and the benefit is that it's an image of my actual signature with the handwritten date over the stamp, so I can spot in a second if it's been tampered with and it's useless stuck on something of any other date.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

OldBBldgGuy: you are writing that presuming that you would see every single document that gets stamped in whatever state you are in...which will never happen. My signature is my actual signature scanned in with high resolution many moons ago so it looks legit. You cannot stop what you don't know is happening until someone gets caught.

I agree with the above though, there really isn't much fraud.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

OldBldgGuy: I use the same method. Recently I started putting a digital signature on the PDF as well if I submit electronically (99.9% of all my work) as I figure it's more professional and can't hurt.

CBSE: How would your method prevent "what you don't know is happening"?

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

TehMightyEngineer: My method does not prevent it. I'm merely making the point that being extremely protective of your stamp is basically useless in today's age of digital media. OldBldgGuy made it sound as though he does a wet stamp, signs it, scans it, makes a TIFF, and then inserts it in his drawing for every single drawing. My point was that is a lot of extra time to go through for something that can be easily duplicated if someone was so desperate to do so.

In all reality, our true last line of defense is the building department. They see enough of each firms work, and presumably have a decent idea of who is working where (for the most part unless changing companies), and know the quality of work of individuals that are stamping drawings that a dramatic change in detailing methods and plan sets to the point that they may see something that looks completely off for the individual stamping the drawings. Case in point, there are two reviewers at the state level that know my stuff very well, and send me an e-mail letting me know that they are reviewing my plans. THIS IS A GREAT CHECK. I think building departments should do this more often as it really is one last check.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

I should say that I do like OldBldgGuy method, quite clever.

RE: Acceptability of Printed Digitally Stamped Drawings (WA State in Particular)

Most of my work (Ontario, not in the States)is in jurisdictions where the building departments are familiar with me and I have had them call me a few times to ask if I stamped some drawings. A couple times they were oddball things, but legitimate. Once it was a drawing that someone had scanned and inserted my stamp, removing the date. It was done by a draftsman working for a small builder who had an old drawing of mine. It was easy to spot because I hand date the stamp, so no date is obvious and I doubt that anyone could remove a date and convincingly forge a new one in. That & good plan reviewers as CBSE says are the best I can hope for for security.

It doesn't take long to stamp a set of drawings; once the TIFF is made (2 minutes) it's only 2 mouse clicks to insert it. I can't physically do it anywhere near as fast, even if I did print the drawings which I usually don't. I occasionally put a digital signature on drawings, as TehMightyEngineer does, and I'm sure it's more secure, but for the most part my work is going to people & places I know so I'm probably not as concerned as I should be.
