RE HWY 121 Alignment QuestionGood deal. I thought that might be the case. For the early exhibits we
were just using a simple offset of the right of way, which created weird
bends in some areas. Adding the radii in the final design will produce
a more accurate alignment/profile. We will avoid fitting where
possible.
Thanks.

Casey,
If the deflection exceeds the recommended deflection at a single joint
of pipe, I would prefer to show a radius. Our desire is to minimize the
use of fittings where possible.

Keith
As we come to certain locations along the waterline, there are
deflections that fall between the tolerances of adding a fitting and
torqueing the pipe. The contractor will like drop a radius in there to
make it work.
Are you OK showing the alignment as above for simplicity, or would you
like these larger deflection areas to have a radius added? The reason I
ask is we are about to start profiling, and although small, these
changes would cause stationing discrepancies that would add up over the
length of the project should we profile everything one way, then change
and have to revise. I’m trying to avoid that possible headache.
We would be happy to show it either way. Thanks.
