Amendment No. 1 —Scope of Work Proposal
Dear Mr.Harder:
This letter presents a scope of work proposal for additional engineering services requested by
the City of Fort Worth for the referenced project. The work tasks include the following items:
1. Updating and repacking the original design documents for Clearwell No.3 and
associated facilities.
2. Providing bidding services and general services during construction of Clearwell No.3.
3. Updating the previously prepared Environmental Information Document(EID),required
by the Texas Water Development Board (TWDB) for State Revolving Fund(SRF)funded
project.
4. Conducting a tracer study for the Phase III ozone contact basin to develop baffling factors
(T10/T) for use in developing disinfection CT for the plant.
A discussion of each of these tasks is presented below.
Clearwell No.3-Design
CDM designed the Eagle Mountain WTP-Phase III Expansion in 2005, to bring the treatment
capacity to 105 MGD. Clearwell No.3 was included as part of this design as an Add-Alternate
bid item. Because the bids were higher than expected,it was decided to remove Clearwell No.3
from the construction project. Clearwell No.3 will increase treated water storage at the plant to
10.5 million gallons. This equates to 10%of plant capacity,a reasonable amount of storage for
proper operation of the plant and pumping facilities.

3. The draft EID will be circulated to the agencies identified in the TWDB DWSRF guidance
for review and comment. APAI will work with the City to draft a public notification and
prepare a presentation for the public hearing. APAI will attend one public hearing.
APAI will also draft a wetland and floodplain management notice for agency

L Prepare a tracer study protocol outlining the procedures,equipment,and supplies
necessary for conducting a tracer study. Coordinate with the plant staff concerning
availability of time,facilities,and desired flow rates for the tracer study.
2. Conduct tracer study at the Eagle Mountain WTP. It is anticipated that set up,tracer
testing,and clean up can be completed in one day. Two to three personnel will assist in

The attached figure shows the fee development for the additional work. The total proposed fee
is$148,000. Please note that the M/WBE firm utilization is 18%of the total fee request. This is
slightly less than the current M/WBE goal for the project. We anticipate completion of the
design phase within six weeks. Construction should take approximately 12 months. The tracer
study should be completed with documents sent to TCEQ within six weeks. If this proposal is
acceptable to the City we will prepare an amendment to our contract for execution.
Please contact me if you have any questions or comments.

HEARING:
SUBJECT: Authorize Amendment No. 1 in the Amount of$148,000.00 to the Engineering Agreement
with Camp, Dresser& McKee, Inc., for the Design of the Eagle Mountain Water
Treatment Plant Phase III Expansion (COUNCIL DISTRICT 7)
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 1 in
the amount of$148,000.00 to the engineering agreement with Camp, Dresser&McKee, Inc., for the
design of the Eagle Mountain Water Treatment Plant Phase III Expansion, thereby increasing the
amount of the contract from $4,645,213.00 to $4,793,213.00.
DISCUSSION:
On August 24, 2004, (M&C C-20235) the City Council authorized the City Manager to execute an
engineering agreement with Camp, Dresser& McKee, Inc., in the amount of$4,645,213.00 for the
design of the Eagle Mountain Water Treatment Plant Phase III Expansion. As part of this contract,
Camp, Dresser& McKee, Inc., prepared a design for a 3.5 million gallon clearwell, used to store
treated water prior to pumping into the distribution system.
On October 25, 2005, (M&C C-21110) the City Council authorized the City Manager to execute a
contract for the construction of the Eagle Mountain Water Treatment Plant Phase 111 Expansion
Project. The 3.5 million gallon clearwell was included as part of the bid package as an additive
altemate, but was not included in the construction contract due to funding limitations.
Amendment No. 1 compensates Camp, Dresser& McKee, Inc.,for the work required to repackage
the clearwell design into bid documents, bid the project and perform professional services during the
construction of the clearwell. In addition, the amendment includes preparation of an environmental
information document necessary to secure drinking water state revolving funds for construction and
an ozone contactor tracer study necessary for the Texas Commission on Environmental Quality
(TCEQ) to approve a higher baffling factor for ozone contactors.
Camp, Dresser& McKee Inc., is in compliance with the City's MI BE Ordinance by committing to an
additional 18 percent M/WBE participation on this Amendment No. 1. The City's goal on this
amendment is 18 percent.
This project is located at the Eagle Mountain Water Treatment Plant, 6801 Bowman Roberts Road,
COUNCIL DISTRICT 7.
