Land design terrain editing with contours

Hi, I am trying to edit the terrain that I made with add contour tool. I would like to descend the terrain to fit to my plans buildings level, but when and line or points with add contour comand it doesn’t descend the terrain enough to touch the points or line and it makes it really coplex.

When I try to edit terrain with excisting contour lines control points, it is really hard because the contour lines are full of control points. I have made the terrain from sites excistings contourlines that have been given for me.

Is there way to siplify terrain contour lines without changing the terrain?
