I don't like to Jackhammer in a basement, aside from the pounding the concrete takes, the dust in the air, and the rough edges to pour back to.
I prefer to hire out a contractor with a diamond blade wet saw.
Nice clean cuts, no dust, they bring the tools with them, no need to pick up a rental and return the rental.
Without seeing what is in the ground, saying it will be easy is premature.
It may be, or not.
A picture will tell us soon enough.
