If the contour curves are in 3D, Array the border curve in Z by the contour increment so there is a border at every level and then proceed level by level with CurveBoolean. Important - the resulting surface will have singularities at the ends of the curve segments which can cause problems in other operations. The NURBS form can represent simple shapes, such as planes and cylinders, as well as free-form, sculptured surfaces. I would need to see the surfaces in question to know if this would help but you may try Untrim on the trimmed edges and then be able to MatchSrf and finally MergeSrf to get to a single srf.
