Bethel Road Drainage Improvements
Postal Site to Freeport Parkway
Construction Status
88157.04
As you requested, the following status report for the referenced
project has been prepared.
Field Survey
On July 5, 1989, our surveyors made a cursory field survey
of the Project to compare the actual construction with the
requirements of the plans. A copy of the results of the
survey is attached.
Horizontal accuracy varies from 0.43 ft. at P.I. Station
16+15.8 to 0.02 feet at Station 20+05.
Vertical accuracy varies from 0.16 feet above grade at Station
15+36.7 to 0.27 feet above grade at Station 20+05.
The horizontal tolerances appear to be within acceptable limits
and well within the available easement. The vertical
tolerances also appear to be acceptable. The flow lines in
the upstream section were constructed slightly higher than
proposed in order to tie in to the existing concrete apron.
2. Construction Progress
According to our measurements, construction has progressed
as follows (construction is proceeding upstream) on July 5.
Culvert Component

Bottom Slab 20 + 05
