What is Rough Grading?
Rough grading is the leveling or sloping foundation for a variety of projects. For example, a new paving project might involve cutting a level roadway from a sloped hill.
For drainage purposes, a ‘level’ road is usually sloped slightly; this is usually done using lasers and not always visible to the naked eye. A road might be graded slightly raised in the center allowing drainage to either side of the road, or graded to slope continually so all drained flows to one side. Rough grading is usually the precursor to finish grading.
What is Finish Grading?
Once the rough grading is complete, finish grading can begin. Finish grading is generally adding or removing the top several inches of surface in order to bring the grading project within the elevation tolerances required for the project, permit or code.
Finish grading also being the graded surface into readiness for materials such as aggregate, asphalt or concrete. Finish grading is often aided by the use of GPS integrated into the grading equipment. Excavating and grading contractors typically use graders and rollers for finish grading.
Pavement Excavation and Demolition
Excavation and demolition is often part of a pavement project. Excavation is usually defined as the removal of dirt. For example excavation would be used in preparation for drainage pipes or utility lines running underneath a pavement project. Excavation is sometimes used to describe trenching or tunneling, especially for larger jobs. Demolition generally describes the removal of a building or other structure. Demolition is often part of a pavement project when structures are removed to make space for a parking lot. Although excavating and demolition are someones categorized together, they are separate parts of a construction or paving job and require different equipment.
No matter the type of grading or excavation services are being performed, erosion control needs to be taken into consideration. Excavating and grading contractors, regardless of what the permit allows, should look at the surrounding area and land clearing and be alert to erosion control issues that may be caused in a land grading project.
Thankfully, erosion control is usually part of the overall grading project and usually required, which means the grading contractor has a set of guidelines to adhere to. Poor erosion control can result in damage to the surrounding area, including natural plant and animal habitat.
