Pipe Network Updates with Dynamo
Stephen Walz demos a simple Dynamo script connect your Pipe Networks to Alignments in your C3D designs so that the Structures and Pipes dynamically update in Civil 3D.

I bet you want a copy of this Dynamo script. Creates and maintains an Alignment station-based dynamic relationship between the Structures and an Offset Alignment. Ok. Any Alignment.
Left unsaid is the rim elevations here are coming from the Corridor surface. This speaks to a good reason to employ design by Corridor approaches to many problems in Civil 3D.
Now you are going to ask about the inlet structures (not shown in this video) that are probably placed on the other side of the road.
