A major problem with this system is that the support structure often conflicts with the excavation and placement of the permanent structure Excavations which use tieback. The test mandrel is sized to be smaller than the inside diameter of the duct so that some deflection of the ducts is allowable. Threats of force can come in many forms, including, but not limited to, the following: • Terrorists or subversives Conventional underground tunneling The mandrel, however, would have difficulties in checking multiple defective parts if it became stuck as a result of the first defect and could not continue its passage through the duct.
