For the deign of ; soldier piles, the active soil pressure should act on one pile- spacing above excavation line and on one pile-diameter below excavation line; the passive soil pressure in the toe embedment �� =hould act on one pile-spacing or two times the pile diameter, whichever is less. The concrete facing should be designed for one half of the above active soil pressure to account for the soil ` arching effect. , When used as a permanent application, the soldier piles from one foot below excavation line to the top should be sand-blasted and painted with protective coatinq for corrosion protection. The �� drilled holes over the toe embedment of the piles should be filled with structural concrete and the remainder filled with one-sack sand-cement lean mix. Construction ISonitorina The hillside stability is a concern and should be monitored during construction. A representative from Geo Consultants Inc. (GCI) should observe and monitor the excavation and construction of the retaining wall. During the excavation and construction of the garage walls, a survey instrument should be used to monitor ground settlement, soil movement and wall deflection. The survey should be carried out twice a week until construction of the walls is completed, and once every week until GCI is satisfied that the ground movement or wall deflection has ceased.
