Claim 17:
18. A method including:
(a) placing at least two jacking devices within a volume of a shoring structure residing within an excavation with a lower edge of the shoring structure below a surface level, each jacking device being positioned in a respective operating position to apply a respective extraction jacking force to a respective jack receiver arrangement mounted on the shoring structure within the volume of the shoring structure, the respective extraction jacking force comprising a compression force applied to the respective jack receiver arrangement and sufficient to lift the respective jack receiver arrangement;
(b) applying each respective extraction jacking force to the respective jack receiver arrangement to lift the shoring structure upwardly toward the surface level;
(c) after applying each respective extraction jacking force to the respective jack receiver arrangement to lift the shoring structure upwardly toward the surface level and with the shoring structure supported against substantial movement in a downward direction away from the surface level with the lower edge of the shoring structure remaining in the excavation below surface level, filling in the excavation with fill material at least in an area below the lower edge of the shoring structure; and
(d) removing the shoring structure from the excavation after filling in the excavation with fill material at least in the area below the lower edge of the shoring structure.
