Backfilling

So today we were lucky enough to visit the house while they were backfilling the hole around the foundation. They filled all the window wells with gravel, then the mountains of dirt around our hole was put back in the hole. I am amazed at how huge the backhoe was and how effortless the operator made it seem. I was kind of suprised at how noisy the whole process was as well. The garage is completely filled in now and I can hardly wait to see what happens tomorrow....could it be plumbing or flatwork or framing or even more backfilling?
