What about revising original prepared by another consultant?
(OP)
This is a 'sister' question in the footsteps of the previous one.
We often work on projects prepared by another consultant and are provided with digital copies of their original works. Many clients require digital copies of the work and take 'ownership' of these documents. Many clients want to retain an up to date digital copy of elements of their facilities.
We then provide modifications to these drawings.
We provide the client with *.pdf scans of the original sealed drawings (actual scan with a single layer).
We have been advising the other consultant of our intent to modify these documents and the manner in which they will be modified. We leave their titleblock/logo on the drawing and affix our own.
The original seal(s) on the paper copy is/are replaced with a note that the original drawings were signed and sealed by ??? on the date ??? for each seal.
The new engineering seal and other seals have a note that the seal(s) apply only to changes denoted by Revision ???.
If the client permits, the original work is 'screened' to 60%. Some clients do not have drawing layers that permit this.
When we transfer 'ownership' back to the client, we include a note on the drawing that each revision was sealed and dated by ???.
Any comments?

For clear modifications, we do essentially what you have done.

That's the way I would have thought... but people here are of the opinion that we are only responsible for the revisions...

Communication with the previous engineer is both essential and a matter of professional courtesy. I would expect no less if the tables were turned.

At the minimum, you ought to demonstrate by analysis that your revisions do not affect the underpinnings of the originator's analysis. This may be non-trivial.
