To seal or not to seal
To seal or not to seal
(OP)
I have a question on having engineer PE seals applied and when it is applicable.
First, we are an OEM and we manufacture various pollution control equipment. One piece of equipment is a flare which is self supporting. We have done the due-dillengence of having a PE run calcs and verify the flare stack meets structural requirements for windloading and seismic requirements and we also ran a MecaEnterprises modeler to verify the design to ensure it passes the structural needs. We drew up all of the details in cad and printed out the 90 pages of calcs for the file.
My questions is: Is it appropriate to have the PE seal these drawings? We disclaim in our proposals any structural PE seals/stamps or additional drawing requirements. We are essentially providing a component on a project that has many more facets. The project engineer did seal their project drawings which does describe the anchoring methods required for the flare base.
We are not required to submit these drawings. We have documented emails from the engineer on the details and drawing update requirements.
All suggestions are appreciated.

Usually for questions like this, the bottom line answer usually should come from your local engineering board or authority.
Two things you could do -
first - get online to your state boards website where there will sure to be the engineering laws and rules/regulations that govern engineering. In most cases there is language that defines the practice of engineering. This might give you an indication whether your flare falls under that category or not.
Second - just call the board and talk to them. They are usually very willing and appreciative when they are contacted to verify the engineering law applications.

Well I guess in that case, his/her calcs are not worth the paper they are wriiten on.
If he/she is a PE in the state, well then get the stamp, what is a set of calcs worth in court without a seal?

The sunshade I bought at Costco did not have a PE stamp, but someone design it for wind load (well, probably not but they should have). Your car does not have mechanical PE stamp under the hood. And so on.
Different kind of insurance and liability.
As an engineer, I have declined this work - you get paid once for the design, the manufacturer makes a bunch of these, then you as the engineer have huge liability exposure for a disproportionally small fee.

Timing has a lot to do with the outcome of a rain dance.

Some states do recognize seals from other states for pre-engineered components, and some don't require submission of engineering documents for many pre-engineered items.
