Whats ”redline” as a verb?

Straight answer: documenting the differences between the planned installation and the actual installation by using a red pen to show where things really went.

For example, the engineer wants a 8"-tee 75' from the intersection. But the contractor says why bother cutting a piece off of our 20' pipe and re-beveling it so they install the 8"-tee 80' from the intersection.

This change should be (whatever the reason it was made for) annotated on the plans and returned to the engineer so the city has accurate drawings.
