excavation company
A contractor that performs earth moving, underground demolition, and preparatory drilling at a building site.
An excavation company is a contractor which performs earth moving, underground demolition, and preparatory drilling on a building site. Excavation companies often perform their tasks from before the beginning of construction until well after foundation work has been completed.
These firms often work in conjunction with a shoring contractor which stabilizes the pit dug by the excavation company.
The work changes the ground or removes underground material in preparation for or during construction. A foundation company builds the foundation system, while shoring stabilizes the excavation; neither activity is identical to digging and moving the earth.
