Subject: Rolling Hills Water Treatment Plant
Facilities Upgrade and 40 MGD Expansion Project
Project No. PW77-060770510050
Chemical Facilities Completion Project
Dear Ms. Godery a:
Attached is a revised engineering services proposal for the Rolling Hills WTP Facilities Upgrade
and 40-MGD Expansion Project, Phase 5-Chemical Facilities Improvements. The scope of work
for this project includes services related to developing design documents and services during
construction. It also includes incorporating the new chemical facilities into the City's O&M
manual currently being prepared by CDM.
We propose that this work be included as an amendment to our existing engineering services
agreement for the project. I will forward copies of Amendment No. 2 under separate cover.
Please contact me if you have any questions or comments.
Sincerely,

ENGINEERING SERVICES PROPOSAL
ROLLING HILLS WATER TREATMENT PLANT
FACILITIES UPGRADE AND 40 MGD EXPANSION PROJECT
PHASE 5 - CHEMICAL FACILITIES IMPROVEMENTS
PROJECT BACKGROUND
The City of Fort Worth contracted with CDM in June 2000 for engineering services
related to the expansion of and improvements to the Rolling Hills Water Treatment
Plant. The work was separated into four phases:
■ I -Study/ Preliminary Design
■ II -Design
■ III -Construction Services
■ IV-O&M Services
The design and construction phases of the project were separated into four packages:
■ Phase 1 -Ozonation Facilities
■ Phase 2-Backwash Supply
■ Phase 3- Plant Process Improvements
■ Phase 4- High Service Pump Station
All four phases of the project have been constructed and placed into operation. The
remaining engineering work to be completed is the plant operations manual. This work
will be prepared under Phase IV-O&M Services.
Upon completion of 90% design of the Plant Expansion (Phase 3 - Plant Process
Improvements Project), a construction cost estimate was prepared. The estimated cost
was greater than the available project budget. It was therefore decided to delete the
flocculation basin improvements,chemical facility improvements, and paving from this
construction project. The Phase 3 construction documents were repackaged,deleting
these items,with the intent to make these improvements in future construction projects.
Amendment No. 1 to the engineering services agreement was executed to include the
additional effort for modifying the Phase 3 construction documents.
The City has decided to proceed with improvements to the chemical facilities and has
requested CDM to provide a proposal for providing engineering services for design and
services during construction for this project. This proposal provides a scope of work,
proposed schedule, and engineering fee for performing the work. Below is the proposed
scope work and associated tasks, related to the original contract phasing.

SCOPE OF WORK
General Overview of Project
The Phase 5-Chemical Facilities Improvements will generally consist of the following:
■ Constructing a new Chemical Building and chemical storage tank area within the
existing dry chemical storage area located south of the existing Chemical Building.
The chemical systems involved include, ferric sulfate,cationic polymer, sodium
hydroxide, and fluosilicic acid.
■ Replacing the existing chemical storage tanks with new stainless steel storage tanks;
■ Installation of new chemical piping and connecting to existing chemical piping;
■ Demolition of existing items within the existing chemical storage and feed pump
areas,including piping, supports,concrete pads,and electrical equipment,that will
not be used.
Engineer has completed the process-mechanical,structural,architectural,and
HVAC/plumbing design drawings to 90% as part of the Phase 3 project. The electrical
and instrumentation&control design was completed to approximately 30 to 50%.
Engineer will prepare 100% complete plans and specifications for bidding the project
based on the original scope of the project. The number and size of feed pumps and
storage tanks will be reevaluated based on recent plant operations and potential future
process requirements.

COUNCIL ACTION: Approved on 10/30/2007
DATE: 10/30/2007 REFERENCE NO.: **C-22492 LOG NAME: 60ROLLINGAMEND2
CODE: C TYPE: CONSENT PUBLIC NO
HEARING:
SUBJECT: Authorize Execution of Amendment No. 2 to an Engineering Agreement with Camp Dresser and
McKee, Inc., for the Design of the Rolling Hills Water Treatment Plant Facilities Upgrade and 40-
MGD Expansion Phase 5 - Chemical Facilities Improvements
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 2 to an
engineering agreement with Camp Dresser and McKee, Inc., (City Secretary Contract No. 26050) for the
Design of the Rolling Hills Water Treatment Plant Facilities Upgrade and 40-MGD Expansion Phase 5 -
Chemical Facilities Improvements, thereby increasing the amount of the contract by $235,000 to $5,388,839.
DISCUSSION:
On June 6, 2000, (M&C C-18062) the City Council authorized the execution of an engineering agreement
with Camp Dresser and McKee, Inc., (CDM) in the amount of$4,598,833. Under this agreement CDM
prepared construction plans and specifications for the upgrade of existing treatment facilities, and the
installation of new ozonation, backwash, filtration and high service pumping facilities to increase the plant
capacity to 200 MGD from current 160 MGD at the Rolling Hills Water Treatment Plant. The design and
construction phases of the project were separated into four packages (Phase 1 - Ozonation Facilities; Phase
2 - Backwash Supply; Phase 3 - Plant Process Improvements; Phase 4 - High Service Pump Station).
During design of the Plant Expansion (Phase 3 - Plant Process Improvements Project), the estimated
construction cost was greater than the available project budget. Therefore the flocculation basin
improvements, chemical facility improvements, and paving were deleted from this construction project. The
Phase 3 construction documents were repackaged, deleting these items, with the intent to make these
improvements in future projects.
Amendment No. 1 in the amount of$555,006, was authorized by City Council on May 25, 2004, (M&C C-
20091) for modifying the Phase 3 construction documents as well as to include several changes to ensure
plant operational reliability. The changes include a filter backwash supply system, an 84-inch diameter raw
water line, plant SCADA and communications loop, engineering service for the development of flocculation
basin design alternatives, and electrical and instrumentation inspection services during Phase 3 and 4
construction.
As part of Amendment No. 2, CDM will complete the design and prepare construction plans for the
improvements to the Rolling Hills Water Treatment Plant chemical facilities and provide construction support
services for a fee not to exceed $235,000.
This project is located in COUNCIL DISTRICT 8.
