Take NCCCO Dedicated Pile Driver Practice Questions - NCCCO Dedicated Pile Driver Operator (DPD) Exam

QUESTION 1 / 25

Before a dedicated pile driving rig arrives on site, the operator notices an area of recently placed, uncompacted fill near the proposed work area. Why is this a concern for machine arrival and setup?

Choose one answer below.

ALoose fill increases the load chart capacity of the rig✓BLoose fill can cause the rig to settle or tip because it cannot reliably support the ground bearing pressure✓CLoose fill is only a hazard for wheeled cranes, not tracked pile drivers✓DLoose fill improves traction and is the preferred setup surface✓
