RE: West Sandy Lake Road - Wing wall Elevation (2)Keith
The wing wall was constructed approximately 2 inches to low. The Top
of the wing wall would be that much below the edge of the sidewalk. The
railing could be constructed on top of the wing wall as it now is by
making the posts of the railing that much taller leaving a relatively
minor negative visual effect. The contractor objected to this option.
We have checked the elevations shown in the plans for this wing wall
and they appear to be correct.

Keith;
The cost to raise the wing wall to match the sidewall elevation
is $2,525.00, do to error in wall plans.
