I am a CO who has encountered a PM and their office who state that they have to go back to the DOR and have them concur and restamp small non-technical edits to stamped drawings or specifications. These edits are things such as adding to the verbiage in the specs "similar or equivalent" to brand name, editing verbiage that makes it seems as if this is design build (i.e......"design of a clean agent fire extinguishing system” but that what the specs and drawings in had are for and in discussions with the PM's office the intent is to install in accordance with the current design of clean agent XXXXX). None of this alters the fundamental intent or purpose of the current stamped drawings or specifications as accepted by the Government. In my perspective, these do not account as "errors and omissions" so no need to go back to the DOR for any restamping or concurrence. However, the PM is persistent that they do need to go back or it will violate the Colorado state licensure boards for engineers and architects. I have found nothing that states this and looking for insight to either yes, we do need to go back to the DOR or that is it not required. Hopefully, some insight or technical or FAR reference to this can be provided to point me in either direction.
