Vacuum Excavation

Vacuum excavation is a tool that is used to confirm, safely expose and examine underground utilities that have been identified using geophysical methods. An air “knife” is used to loosen the soil and a powerful suction hose is used to remove the soils overlying the utility. Once the target utility has been exposed, measurements can be made regarding the composition, diameter, depth and centerline of the utility. This information is often crucial for design/build projects, pipeline installations and for when soil borings are planned near critical (petroleum and fiber optic) lines.

The results can either be marked in the field or documented in a surveyed site plan or on a site figure prepared and signed by a Professional Licensed Surveyor.
