RE Old Town Coppell Grading questionsSome of the same problems as I stated earlier yesterday, these CAD files
being messed up are costing me money to fix, slowing me down and causing
potential screw ups. We need some help here from FN.

Subject: Old Town Coppell Grading questions
Dan:
I have been tasked with staking the curb on Houston Street from the
intersection of Main, East to the intersection at South Coppell. I have
questions regarding the following data.
1. At the intersection of S. Coppell & Houston, (sheet PV-7)
there is a PI called at Station 9+67.29, with coordinates given. The
coordinates appear to be more correct. It appears to be at Station
9+96.79 -42.47’-RT.
2. At the same intersection. On sheet PV-7, I’m having trouble
with the following: the PVI data from the profile VS. the Point table
calls, and digital station data:
PVI Station 9+97.29; when projected to the proposed Left and Right Curb
lines, follows and intersects the gutter line, but is delineated as a
top of curb in the profile view.
PVI Station 9+91.85; - when projected to the proposed Left and Right
Curb lines, follows and intersects the gutter line, but is delineated as
a top of curb in the profile view.
PVI Station 9+86.79; - when projected to the proposed Left and Right
Curb lines, follows and intersects the gutter line, but is delineated as
a top of curb in the profile view.
The Left Curb slope, when calculated between PVI station 9+68.08 to PVI
Sta 9+86.79 results in a slope of 4.9% , The Right Slope at 2.9% The
Profile calls 4.4% & 2.6% respectively.
3. The section for Station 6+50 Gives data for LT. TBOC-516.71,
RT-TBOC-516.61. that section appears to be within an ADA ramp. Am I to
assume that data should be LT- EP=516.21 & RT=-516.11
As far as the Houston/ South Coppell Intersection, could I get an
exhibit with top-back of curb-elevation clarified on the above stations
if correct, or updated data if not, as well as Top-of Curb- elevation
and station data for all points of curvature and tangency from station
9+68 to the end?
