(: (/ /7) <br /> lierracon <br /> PROJECT: Staples Replacement Retaining WallPage 3of 16 <br /> JOB NO. 81175122 Date 3/12/2019 Comp. By ZLK, FSM CHECKED BY: RDL <br /> ANALYSIS <br /> Soldier Pile Design: <br /> Soldier piles were designed using Shoring Suite v8.10 by CivilTech software. Outputs of piles sized for a single <br /> row of tiebacks are attached. Pile lengths vary due to changing existing ground conditions behind the wall. <br /> Permanent Concrete: <br /> LRFD design for reinforced concrete as per building code. Calculations are included after the outputs for <br /> soldier pile sizing. <br /> RESULTS <br /> Retaining Wall (summary): <br /> TIEBACK ROW 1 <br /> PILE SHAFT STEEL ELEV. ELEV.
