Stamping non-essential engineering documents
Stamping non-essential engineering documents
(OP)
I'm being asked to provide a professional engineering stamp on non-essential engineering documents such as instrument datasheets, equipment datasheets, etc. I say non-essential, because these datasheets are required deliverables for some projects, but not others. Is this normal or should I push back?
In my career I've seen thousands of these datasheets issued without an engineering stamp. I'm not sure our organization can operate competitively if simple documents must be reviewed and stamped by a professional engineer, while our competitors are not doing so.
Advice welcome, thanks!

The question about who prepared the work versus who stamps it, is not the matter I'm asking about here. (In this instance I did supervise the engineer-in-training who completed the work.)
Thanks TGS4, I have reviewed APEGA "Practise Standard for Authenticating Professional Documents". It looks like whether you stamp a datasheet (or any document) hinges on whether it is a "professional document" based on "engineering work". It's clear that an engineering stamp is required on construction documents based on engineering calculations (structural drawings, piping and instrumentation diagrams, etc). Not so clear for documents where information is taken from professional documents - datasheets are based on info from process flow diagrams, line lists, mechanical equipment lists, etc - but are non-critical documents that are sometimes excluded from projects.
Is an engineering stamp normally provided on a purchase order?
A datasheet is a document that will normally be included in the PO, or alternatively the equipment specifications will need to be provided in some other way in the PO (block of text, email, brochure, model number, or somesuch).
RE: Stamping non-essential engineering documents
From my experience, I've never seen an engineering stamp on a PO.
I have also never seen a stamp on a datasheet (if my definition of datasheet is the same as yours). Datasheets are typically marketing material, and rarely is an engineer in the approval process for the datasheet. Too many typos in parts catalogs, for example, to risk your license and liability on stamping a datasheet.
If your definition of a datasheet is the raw data from a test, again the answer is no. The engineering stamp goes on the final report that explains the test and the interpretation of the results (of the raw data), not the data itself.
In general, I don't stamp anything that I don't want the liability in maintaining. Because 1) I need to be in integral part of the process (or project) that created the document I'm stamping, and 2) I need to keep a record of everything I stamped. Both of those can end up being a very large burden.

I'm not a fan...and I'm a Permit Holder, have been for 20 years.
The way it used to work - and the way it made sense to me - was:
If you do something as an engineer that someone else pays for, receives and uses towards making a decision regarding the implementation of something, you ought to be prepared to stamp it. If you're not, then you ought not to be doing it in the first place. That's why I have so much heartburn with "technologists" and "technicians" doing stuff that, simply put, they lack the credentials to do. Elitist, perhaps, but it pains me to see folks who derive a sense of entitlement to "do stuff" but are conveniently able to duck the accountability that goes with it.
To me, my stamp is my statement that says, "Here, I think this piece of work is correct, and I'm proud of it because I think I've done a good piece of work, which, by the way, I am actually qualified to do.". So, if someone wants me to do a data sheet and stamp it, then I do it and stamp it. The acid test, in my mind, is:
"OK, I've put something on a piece of paper that someone who pays me is going to use to make a decision. Would they be able to make that decision without what's on this piece of paper that I've been paid to give them?" If no, then it's stamp-worthy. If yes, then they didn't need me in the first place and they can go do their own thing, whatever that is.
I think data sheets and calculations always fall into a gray area, it's a bit overkill. That said, I have learned to simplify my life by being prepared to stamp whatever I am being asked to do, which, by extension, means that I don't do stuff that I'm not prepared to stamp. One perspective directly supports the other.
The minute, for example, someone says, "I'll do it but I won't stamp it" is the minute, in my mind, that they cease being an engineer.

In my opinion, there's an epidemic of under-stamping going on, which leads to engineers taking a blasé attitude towards their work, which leads to problems. If you, as an engineer, do work that is worthy of being an engineer, then you should be prepared to stamp it. (Noting that even if the document is not authenticated, you as an engineer still have responsibility for it, as if it were stamped. So your responsibility and professional liability for it is there anyways.)
RE: Stamping non-essential engineering documents
SNORGY - I think your descriptions are very good and I agree with them.
One thing I might add/adjust to your descriptions would be that the "something" that you do would have to be engineering work (as defined by your local authorities) for any of this to apply.
If I write a data sheet about possible various aesthetic treatments of precast cladding panels, for example, that isn't engineering work and thus I should never stamp something like that.
I don't know exactly what the content of these data sheets are that PetroBob (the OP) describes so can't comment directly on them.
