Stiver Engineering provided a shoring design for the launch and receiving tunnel shafts, including portal design implementing soldier piles and the shaft design implementing sheet piling and wale sets. Calculations and a finite element analysis (FEA) were performed for a 108-inch diameter tunnel steel casing pipe. Calculations for grout pressure used to fill voids outside the casing pipe were also provided.
