MSE Wall - Off Plumb
MSE Wall - Off Plumb
(OP)
Approximately 15ft tall MSE bridge abutment wall (non-load bearing, enclosing a pile and pile-cap system), observed during construction that it was going up slightly off plumb (away from fill), but visually perceptible when looked at carefully. After erection, it has come up for situational assessment and if needed, remediation recommendations. Obviously, it is too early to observe if the tilt is progressive. However, if it is observed to be non-progressive, is there a need to remediate with this type of system? If so, what might that remediation be? Is there any structural concern at its current condition, considering that it was observed to be going off-plumb during erection?

Aside from the aesthetics, someone is not getting what they paid for ( not even considering the failure aspect )
Constructing a MSE wall out of plumb is not uncommon when not following the installation procedures provided by the designer. If the backfill is "sand", and the coping and or level pad has not been completed, I have seen *sections* of walls "eased back plumb with a trackhoe.
Deconstructing and reconstructing of course will be expensive, but also the prudent thing to do.
My wild speculation would be that during bkfl placement a compactor or such got too close to the wall and pooched it out.

Then, you might be in a better position to estimate the chances of failure, of course having made some measurements of any progressive movements.

and i would never suggest trying to nudge a wall with a trackhoe. if it's properly compacted fill then you're wasting your time anyway without even considering all the effects of what happens if you do manage to actually lean the wall back in to the fill after it's already constructed.
