Soldier Pile and Lagging is an earth retention system consisting of steel H-piles driven or placed in drilled holes.  After the soldier beams have been installed, the earth is excavated along one side of the beams to expose a cut face of earth, and to partially expose the front faces of the beams.  Then lagging is installed with either timber or sprayed shotcrete to hold back the soil.  The soldier pile wall design is based on actual elevations and dimensions.  Depending upon the geometry of the wall and soil conditions, tiebacks may be installed required to provide additional lateral resistance.   Tie backs are most commonly required when excavations occur near existing structures and utilities especially when deflection tolerances are stringent and when excavations are greater than 20 feet.
