Soil Nail Wall Shotcrete not centered on Nail

[Zeke]

In a soil nail wall construction, the contractor placed the nail at the bottom of the excavated lift, then placed rebar and shotcrete, then excavated. The result is three nails do not have the shotcrete centered around the soil nails. Is the tributary area critical in this first layer of wall. There is a final layer that has rebar and shotcrete of five inches over this one once all lifts have been excavated. Do we keep going, or is repair work required?

I think you'll have to look at the moment due to the center of the loading not being at the center of the restraint (P*delta), and compare that to the bending capacities of both the shotcrete caps and the soil nail itself, unless they're restrained by the final layer, then it's the capacity of the final layer that will need to be checked.

OK, thank you for the response.
