Subject: 2004 CIP Contract 26
Supplemental Agreement No. 1 —Storm Drain Outfall Replacement
Dear Mr. Argomaniz:
TCB prepared plans and contract documents for the subject job, and assisted the City of Fort Worth
with bidding the project. Prior to the bidding phase, TCB had recommended that storm drain
improvements be part of the construction documents, and they were included as an alternate bid.
After the job was bid, the City of Fort Worth decided to incorporate some storm drain improvements
along Provine Street, and increase the design criteria from a 5-yr to a 100-yr storm. A meeting was
held on November 14, 2006 to discuss the inclusion of these storm drain improvements into the
construction project(Attachment A). As a result of that meeting, the City requested that TCB provide
a scope and fee to redesign the storm drain improvements along Provine Street to contain flows from
a 100-year event. The scope and fee were provided in a previous request dated November 21, 2006.
At the same meeting, there was a discussion in regard the capacity of the existing outfall pipe that
drains storm water from Provine Street to an existing 54-inch line located west of Ederville Road. This
existing outfall pipe does not have adequate capacity to carry the 100-year flows from the proposed
Provine Street storm drain system to the 54-in line. TCB was asked to prepare a scope and fee to
redesign the outfall to convey the 100-year storm.
TCB prepared a scope and fee for the proposed outfall pipe and combined it with the November 21,
2006 agreement. The combined agreement was termed Supplemental Agreement No. 1 and the
executed amendment was signed on February 19, 2007 (Attachment B). The work in Supplemental
Agreement No.1 included the following tasks and associated fees:
Tasks Fee
S-Curve and 100- r flows
1. Revise horizontal S-curve on Provine Street $3,850
2. Redesign storm drain to contain 1 00- r flows $7,640
Subtotal of Task 1 and 2 $11,490
Upgrade Outfall Pipe
3. Survey $2,764
4. Easement $2,270
5. Design and modify Provine plans $8,466
Subtotal of Task 3, 4, and 5 $13,500
TOTAL OF SUPPLEMENTAL AGREEMENT NO. 1 $24,990
Upon execution of Supplemental Agreement No. 1, the City of Fort Worth gave TCB the Notice to
Proceed for only Tasks 1 and 2. The City asked TCB to hold off on the remaining tasks.
With regard to Tasks 3, 4, and 5, the City of Fort Worth contacted TCB on May 16, 2007 and
requested that these tasks be performed under a separate contract. Based on this request,TCB will
prepare a separate proposal to perform the work necessary to design the outfall pipe.

This letter has been written to formally amend the February 19, 2007 Executed Supplemental
Agreement No. 1 to exclude the work and fees necessary to design the Outfall Pipe. The February 19,
2007 Executed Supplemental Agreement No. 1 should be reduced from a total of$24,990 to a total
$11,490.
Should you have any questions or need additional information, please contact our Project Manager,
Matt Abbe at 817.698.6722. A proposal to perform the work to design the modifications to the Outfall
Pipe will be submitted shortly.
Sincerely,
Ann Kovich, ICP

The purpose of this meeting was to discuss the drainage improvements recommended as part of
the above referenced project, in particular, the improvements recommended along Provine Street.
Currently, the section of roadway between Ederville Road and Normandy Road contains one pair of
inlets located at a sump near mid-block. Based on the drainage calculations performed during
design, TCB recommended that additional inlets be installed along Provine on either side of the
sump. Because the required construction budget may not be available to include the additional
storm drain, and because no drainage issues have been reported in this area based on the City's
database, the City requested that the additional inlets and associated storm drain pipe be included
in the bid as an alternate. Bids have been received and the low bidder, Gilco Contracting, Inc.
submitted a bid for the drainage improvements along Provine of$74,461.60. Below is a discussion
of the elements of the meeting.
Argomaniz gave an overview and update of the project. Bids have been received, but have not yet
been awarded due to Water Department funding issues. The M&C was prepared without the
inclusion of the additional storm drain improvements at the request of TPW staff. Since the time of
the bid opening, Argomaniz and Jann attended an on-site meeting with several homeowners that
live along Provine. During this meeting, the residents noted that flooding issues were present
during most rain events, especially near the"S" curve and location of the sump.
Jann noted that based on the calculations, the roadway did not have the adequate capacity to carry
flows generated by a 5-year storm event in accordance with City of Fort Worth drainage criteria
without the additional inlets. Jaafari questioned whether an increase in the roadway width from the
Page 2
proposed 28-feet up to the existing 30-foot width would provide adequate capacity for the flows
thereby meeting the drainage criteria. Jann noted that this difference in capacity between the two
sections was negligible and would not address the drainage issue.
Based on COFW drainage criteria, the design would require the 100-year event to be contained
within the ROW. Due to the existing grades, Provine Street was designed with split curbs. Eubanks
noted that because the roadway utilized a split curb design the 100-year event flows would most
likely not be contained within the ROW. Further he noted that the inlets and storm drain pipe should
be designed to contain flows from a 100-year event.
Eubanks also questioned the capacity of the existing storm drain pipe connecting the existing sump
inlets to the outfall at the City owned lake across Ederville Road. Based on the total 100-year flows
calculated, it appears that this line would not have sufficient capacity to carry the flows once the
improvements along Provine are implemented.
Eubanks noted that his group is agreeable to provide funding for the storm drain improvements
along Provine Street in addition to an upgrade of the storm drain pipe from the sump to the outfall.
The re-designed storm drain improvements along Provine will be included in the construction of the
roadway. The upgrade of the storm drain line may be included in the construction of the roadway,
or based on the schedule, may be constructed as part of another project.
TCB will provide the City with a request for supplemental authorization to re-design the storm drain
improvements along Provine to contain the 100-year event. In addition, TCB will determine the
need for an upgrade to the existing outfall pipe. TCB will also provide a scope and fee to design the
upgrade to this line.
