Topo survey deliverables for civil engineer doing site plan

Here's the premise of my questions: A boundary survey has been done decades earlier and the corner monuments are found, staked, and undisputed. A new surveyor comes in and does a topo survey with a conventional, non-scanning robot and collects around two thousand points. He hands off the data to a civil engineer who is going to do a grading plan and overall site plan to be submitted to the AHJ to begin a permit process. It's a rural residential property in the western US. 

Questions:

1. Do you just submit the list of points exported from the data collector as a .csv file with a sketch of pertinent landmarks (such as the corners) including elevation datum and basis of bearings, and the civil engineer makes the contour lines?

2. Or do you make contour lines and deliver it in a .dxf or .dwg file?

3. What software do you (or the civil engineer) use to create the contours? Autodesk Civil 3D? 

4. Do these questions make any sense?
