Hi Aaron, nice to hear from you again!
I'd forgotten about that page, but that's where I must have got the original version...
As you point out, there is some confusion around the version which Graphisoft is using as it refers version E1557-1997 and then in the pop-up window references Uniformat 2010 which are two different classifications although they have a similar origin.
The E1557-1997 version refers to a Uniformat II standard published by ASTM which has actually been superseded by a more recent version ASTM E1557 - 09(2015) (see <
https://www.astm.org/Standards/E1557.htm>).
The pop-up window references Uniformat 2010 which is actually the one I am looking for and the one indicated in the referenced PDF. It is jointly published by CSI/CSC (see<
https://www.csiresources.org/practice/standards/uniformat>).
I've never gone through and compared the two versions but this article hints at the confusion that can occur if both are used on the same project: <

I've emailed Graphisoft and they are going to confirm which version they actually used in their classification.
The attached screen snap shows the two referenced versions...
