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, CAMP DRESSER&McKEE INC. J. Dan Shannon, P.E. cc: Richard Sawey (CDM) File: CO-1.0 consulting•engineering•construction-operations 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. I of 5 s/z7/zoo7 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. Project Tasks I. STUDY/PRE-DESIGN PHASE A.

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. http://www.cfwnet.org/council_packet/mc_review.asp?refnum=C-22492 11/5/2007 M&C Request Review Page 2 of 2 Camp Dresser& McKee, Inc., is in compliance with the City's M/WBE Ordinance by committing to an additional 27 percent M/WBE participation on this Amendment No. 2.
