A method for in situ relocation of an underground utility including the steps of inserting, extending, raising and continuing to raise. The inserting step is carried out by the inserting of at least one lifting member down into the ground alongside the underground utility.

The raising step raises the lifting member causing the lifting bracket to engage a portion of the underground utility. The continuing step continues to raise the lifting member until the underground utility reaches a predetermined position.
