A manhole is a concrete lined hole in the ground with heavy shoulders at the top to support the lid and anything that drives over it. Breaking it down would require a jack hammer or equivalent mounted on a scoop loader arm.

I guess breaking the walls before it is filled in.
In any case, they'll explain it to you.
