as in the title - just tried to super force build over space ship remnants and this is impossible.
Game is an unmodded Space Age
In the attached files:
-screenshot
-save game from which the screenshot was taken

Those items have a property non-destructable=true which means they can't be built on and robots won't pick them up.

There's a better description elsewhere, but I can find it. This tells part of the story.
