Subsurface Utility Investigation

T-Rex utilizes electronic Designation, “air knife” and hydro excavation for SUE.

Quality Levels of SUE

Quality Level A - Vacuum Excavation:  The use of non-destructive vacuum excavation to determine the exact horizontal and vertical position of the utility.

Quality Level B - Designating:  Employ geophysical methods to designate the horizontal position of the known utilities that lie within the project area.

Quality Level C - Surface Feature Survey / Inventory:  Assessment of site utilities and correlating this information with existing utility records.

Quality Level D - Records Research:  Provides a feel for the overall utility congestion and is limited to project planning and route selection.

  *T-Rex can provide personnel for manhole investigation and collection of

utility data to assist in Quality Level C.

Deliverables

SUE Deliverables Include

Photo documentation and “test hole data sheets”can be provided for every excavation.
