Dear Mike:
Neel-Schaffer, Inc. offers additional Professional Engineering Services for this project. These
additional services were requested by the City of Fort Worth to address the moving head cut.
That head cut has moved approximately 200' in the last two years.
This work generally falls into two categories. The first relates to the overflow channel. The
second addresses the low flow culvert and existing stream.
The overflow channel, with limited Contractor supplied field data, will be modified to deepen it
(to match the newly eroded stream flowline) and shorten it (to reduce the amount of excavation
and save money). It will also include relocating the drop structure from the old location of the
head cut to the end of the newly installed box culverts. There are areas where no additional field
data have been provided that will be generalized in the revised plan. Field modification will be
required to match the concept being developed. Another task related to the overflow channel is to
redesign the culvert apron (also being relocated downstream of the drop structure) and the ACB
and TRM erosion protection measures. This requires modifications to sheet 13 (Concrete
Structure Details) and sheet 15 (Drainage Channel Plan/Profile). New sheets 27 (Revised
Overflow Channel Plan/Profile) and 28 (Revised Downstream Concrete Apron Details) will also
be required.
The second category includes addressing the head cut in the existing stream. The 36" low flow
culvert will be extended about 50' to the end of the existing grouted rock rip rap. From there the
existing streambed will be lowered about 3' for another 50' to tie in the current location of the
head cut. Erosion control measures will be provided for culvert outfall. There are AT&T
facilities in the area of the stream grading that might be impacted. This work will require
modifications to sheets 14 (Concrete Structure Details), and also sheet 15 (Drainage Channel
Plan/Profile). A new sheet 29 (36" Culvert Extension and Existing Stream Modifications Plan
with special pipe connection details) will also be needed. The 36" pipe extension will be
profiled.

The head cut has now exposed part of the newly constructed sewer manhole. Erosion protection
measures will be designed for that manhole. These will be shown on the new sheet 29.
The Section 404 Permit will have to be revised and resubmitted to the U.S. Army Corps of
Engineers for approval. This is included.
No survey work is included. The Contractor provided a few shots to assist with the redesign. No
other revisions to sheets are included. No other permitting (road closure, trees, grading, etc.) is
included.
The proposed increase to the contract is $26,534.00 for these additional services. All additional
services will be performed in accordance with the original contract dated October 10, 2018 (City
Secretary Contract No. 51385).
