Subject: Request for Supplemental Agreement#2
Central City Bridges—City of Fort Worth Contract No. 33771
Dear Mr. Harwood:
At the Central City Bridges SRC Meeting on April 11, 2007, the TCB design team received instructions
to continue moving forward with the design of the three bridges in spite of channel modeling work that
was yet to be completed. The thought at that time was that the channel configuration would not
change as a result of future computer modeling efforts. However, over the course of the next few
months, the channel changed considerably due to H&H considerations and discussions between the
Corps of Engineers, CDM, TRWD and TRVA staff. As a result of these channel modifications, the
TCB design team presents the following scope of work for items that are not part of the original project
scope.A detailed breakdown of the required effort and fee for each task is provided below and on the
attached spreadsheet.
The following assumptions are the basis for this supplemental agreement:
1. Tasks 1, 2, 3 and 6 are based on a lump sum compensation basis. Tasks 4 and 5 are
reimbursable on a time and materials basis with the fee not to exceed the amount shown.
Time and material tasks shall be invoiced based upon the hourly wage schedule attached to
this letter as Exhibit A.
2. Two additional Steering Committee meetings will be held per the original scope. We assume
one meeting in January 2008 and a final meeting in February 2008.
3. No major design revisions will occur after the Steering Committee meeting in January 2008, or
after the results of the physical model are complete in January 2008.
4. No major revisions will occur to the channel configuration provided to TCB in September 2007.
5. One additional HEC-RAS model incorporating the revised bridge designs will be completed by
CDM. No additional HEC-RAS modeling will occur.
6. For the completion of the Categorical Exclusion documents, no additional public involvement
will be required beyond the original MAPO included in the original scope.
7. If additional historical documentation (i.e., a de minimus 4f) is required for the completion of
the Categorical Exclusion documents, such documentation is not included in this scope of
work.
8. Schematic documents will not include any proposed local streets shown in the Trinity Uptown
Plan.
9. No additional meetings with the USACE or TxDOT bridge division staff will occur during this
concept design phase.

Subject: Engineering Letter Agreement for Supplemental Consulting Services
Dear Ann:
Pursuant to the email correspondence on October 1, 2007, please consider this letter
agreement to provide services to assist TC&B with supplemental H&H modeling of the
redesigned bridge concepts for the Central City Project. We understand that these
supplemental modeling services will be provided to assist in identifying the hydraulic
impacts of the new bridge designs only. In order to perform these services,CDM will require
detailed CAD drawings showing plan and elevation views of each bridge,with station and
elevation data identified perpendicular to the channel. This work will include:
• Incorporating the revised proposed bridge sections by TC&B for North Main St.,
Henderson Ave. and White Settlement Rd. into the current HEC-RAS model;
• Evaluating the impact on the TRVA hydraulic design including water surface elevations,
velocities, and valley storage;
• Attendance at one meeting to discuss results of the model.
These services are untended as supplemental modeling to determine, in general, the viability
of the revised concepts to satisfy various project constraints. They do not include:
• Final model configuration or regulatory submittals;
• Written reports;
• Changes to civil and/or grading plans;
consulting•engineering-construction•operations
CDM
Ann Kovich
October 11, 2007

• Other changes to bridges,channel sections, or structures;
• Additional HEC-RAS modeling to nutigate for potential hydraulic impacts from the
redesigned bridges.
The not to exceed amount for these initial services,under this letter agreement, is$9,000. We
understand that prior written approval must be obtained for any additional efforts which
exceed this amount.
If this lett •agreement is acceptable, please sign both copies and return one signed agreement

DATE: 3/4/2008 REFERENCE NO.: **C-22698 LOG NAME: 20TRVBRIDGEAMEN
CODE: C TYPE: CONSENT PUBLIC NO
HEARING:
SUBJECT: Authorize Amendment No. 2 to City Secretary Contract No. 33771 with Turner, Collie and Braden
for Professional Engineering Design Services for Bridges Located on North Main Street,
Henderson Street, and White Settlement Road Over the Future Trinity River By-Pass Channel
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 2 to City
Secretary Contract No. 33771 with Turner, Collie and Braden for Professional Engineering Design Services
for bridges located on North Main Street, Henderson Street, and White Settlement Road over the future
Trinity River by-pass channel in the amount of$215,744 thereby increasing the contract amount to
$1,542,744.
DISCUSSION:
The 2004 Capital Improvement Program included funds which would supplement other funding sources for
design and construction of several components to support Trinity River Vision.
On July 11, 2006, (M&CC-21560) the City Council authorized the City Manager to execute an agreement with
Turner, Collie and Braden (TCB)for the Conceptual and Schematic Bridge Design/Engineering and
Environmental Analysis for the Fort Worth Central City Project, also known as Trinity Uptown Bridges in the
amount of$1,321,750. The scope of work for this contract included:
• The conceptual design of the three Trinity Uptown Bridges in the first phase in the overall development of
Trinity Uptown and the Central City Project;
• Completion of an environmental document for each of the three bridges per TxDOT requirements;
• Comprehensive project management for all tasks and project phases;
The agreement was subsequently administratively amended (City Secretary No. 35588), to provide hydraulic
modeling, which was not include in the scope of work in the original contract, in the amount of$5,250.
Over the last nine months, the U.S. Army Corp of Engineers (CORPS) has been performing additional
channel modeling to adjust the original proposed by-pass channel. As the schematic design of the three
bridges over the future Trinity River By-Pass Channel was being developed, direction was given to proceed
with the schematics even though the CORPS was continuing channel modeling work that had yet been
completed. The consultants and staff have identified additional work that was not included in the original
contract and find it necessary to submit Amendment No. 2 for this contract.
In a letter from TCB dated December 28, 2007, additional work was identified which exceeds the scope of
work from the original contract. A detailed breakdown of the additional work a-nd-proposed fee for each task is
as follows:
• Revise Schematic Plans and Conceptual Bridge Design;
• Update Exhibits for Property Impacts;
• Hydrologic and Hydraulic Modeling and Access Exhibits for TRWD;
• Additional project meetings and management beyond what was originally scoped;
• Construction Sequencing Workshop with stakeholders of the bridge construction;
• Revise Categorical Exclusion Documents due to changes by CORPS; and
• Additional Categorical Exclusion Documentation required.
This proposed amendment will allow for TCB to perform the additional work. The amount of the proposed
amendment is $215,744. City staff considers this fee to be fair and reasonable for the scope of services to be
performed.
TCB is in compliance with the City's M/WBE Ordinance by committing to an additional 15 percent M/WBE
participation on this Amendment. The city's goal on this amendment is 15 percent.
This project is located in COUNCIL DISTRICTS 2 and 9, Mapsco 62V and 62Y.
FISCAL INFORMATION/CERTIFICATION:
The Finance Director certifies that funds are available in the current capital budget, as appropriated, of the
Street Improvements Fund.
