I am not certain when this particular Skill Builder became available, but there is one available titled:
Managing an AutoCAD Civil 3D 2008 Project with Autodesk Vault
This Skill Builder is a 20 page .pdf file that demostrates how to set up a AutoCAD Civil 3D project using Autodesk Vault, how to modify project structure with Vault, and contains some best practices.
For those that are just starting down this road this can be very useful. For others this can be a good refresher.
