I'm trying to create an all new existing surface over existing ground. I have a TIN surface of the EG, and I have drawn overlay splines that describe the new surface, but I have no idea on how to go about creating that design surface. Can anyone offer hints or direction?
It is a compound surface, open on one end and closed all around on the other, somewhat like a half of a football stadium, but with an irregular upper edge because I am needing to figure out cuts and fills to manipulate the EG into this new surface without costly major terraforming. There is about 40-50' vertical elevation between the "field" and the upper rim with a generally constant 7-10 deg. slope all around. I'm just at a loss to figure out how to approach this project, and am quite new to Civil 3D.

By splines I assume you mea digitized contours? I don't believe splines are accepted object data. turn them into plines and you can add them as contour data. You would be better served by adding proper breakline data i.e. Feature lines and or gradings.
Its hard to say without a picture, and written prose can be beguiling, but it sounds like a few tutorials wouldn't hurt.
