If you're building a new home, one thing you'll often see on the site is an excavator. The general contract usually contracts an excavation service provider to clear the ground, move earth, remove topsoil, dig trenches and prepare the land for below-ground activities.
Some established general contractors have their excavators to work with, but most hire or subcontract when the need arises. Most of the excavation jobs take a few hours to a few days to complete making it economical to contract rather than buy the machinery.
