we took out about 500 SF of concrete driveway and about 100 SF of sidewalk this fall and it took 1 guy in a skid, plus one one on the ground to help in breaking the concrete at the joints about 2 hours to take out and load up.We also took out a stoop. The stoop was the hardest becasue it was rebared into the foundation and it was a soild pour, which was odd for a stoop poured about 3 years ago in our area (most are hollow).
No need for a concrete breaker. Skid steer, forks and a guy with a sledge hammer and you can get it out in no time. If you have a big enough truck that is probably about 1.5-2 loads. We loaded up our International and a trailer. We were pushing the envelope with our weight, but the job was about 1 hour away and we didnt want to make 2 trips.
I want to say I charged around $900 to remove the concrete and we made money all day long. We get to dump concrete for free at a local asphalt plant, so I dont have any dump fees.
