Using the software APile, the team was able to select piles for the abutments and piers based off of the required axial capacity. A group of four 36 inch diameter piles will be used for both the abutments as well as the piers. An embedment depth of 88 feet is required at the piers while a depth of 101 feet is required for the abutments, putting the piles into the dense sand stratum for both locations. Next the lateral deflection of the piles was determined using the software Group. Five separate load cases were analyzed for the pile group at the abutments and the piers. The lateral deflection at the abutments was under 1 inch for all five load case scenarios. However, the deflection at the piers exceed the maximum allowable deflection. Therefore, the team will need to consider other options for the abutment design.

Using the EMBANK software the team was able to analyze the settlement of the soil profile under the approach embankments.  The soil strata used for this software was selected from the soil profile created using the boring logs, more specifically Boring B-16.  The software tested five separate scenarios in order to find the maximum settlement, which included creating sub layers for the strata of organic clay.  The maximum settlement was calculated to be 32.59 inches, or 2.72 feet, when the organic clay layer was split into four sub layers.  These calculations reinforce that soil remediation is a crucial element of this design.
