You cannot offset profiles or projected featureline’s in profileviews (that I know of) which is a real pain, especially when you are wanting to check ground cover above existing services to your design profile or surface. To get round this you can
1. Copy the design profile and then raise or lower the new profile by the required cover depth. The downside of this method is that the copy of the profile is not dynamically linked to the first profile so if you update the profile the copy does not up date.
or
2. Use featureline. Most likely the as built services are surveyed as a 3dpolyline string or featureline’s you can make copy the featureline’s to a new site called offset and then rise of lower the new featureline the required cover.

You can create a new surface and then paste in the existing surface. Creating a profile from surface of the new surface with provide the same result as 1, but be dynamic.
