Excavation contractors undertake various construction operations, such as moving or displacing earth, rock or other material from above or under the ground. Some other services provided by excavation contractors include digging basements, removing snow and demolishing buildings.
While interacting with professionals from the excavation industry you will need to be aware of industry jargon. This guide will familiarize you with certain excavation contractor terms, such as clearing and grubbing, trench excavation, rough grading and fill dirt.
Clearing and grubbingBefore the excavation work can begin, clearing and grubbing of the site is necessary. This is the primary task of an excavation contractor. If you are a client, you can specify the extent of clearing and grubbing that needs to be done at the site.
Rough gradingRough grading involves cutting and filling of earth at a site prior to the final work. This is another task that excavators can perform.
Trench excavationMany excavation contractors offer trench excavation services, where they dig trenches of the dimensions specified by the clients. A trench is a depression in the ground that is narrow as compared to its length and has considerable depth.
