How do I get rid of a workbench fixed to thewall and floor of my basment?

Question:It runs along the concrete wall and its a massive waste of space.The surface is 3.5 feet ground.It has no practical use.I'm thinking electric chainsaw.

Answers:
A sawsall with a good blade will cut through the bench very easily and will be easy to control. An electric chainsaw will work, but the sawsall has blades for steel too for cutting through bolts. Good luck
