Dear Ms. Rafalko: 1 am pleased to submit the enclosed Amendment No. 5 to City Secretary Contract No. 27615 for the South Shore Low Pressure Sewer System. The additional services include preparing contract documents for installation of grinder pumps on individual lots and providing pre-construction and general construction administration services for the installation of grinder pumps,increasing the overall length of gravity sewer from the original scope, and designing low-pressure sewer line for additional length of sewer. I. Grinder Pump Installation The original contract scope included providing specifications for the residents along the low- pressure sewer system portion of the project to purchase and install grinder pumps on the individual lots. During the course of the project,the City has decided to take responsibility for purchasing, installing and maintaining the grinder pumps on the individual lots. The City proposes to obtain a general contractor to furnish and install the grinder pump stations for approximately 100 homes. The proposed scope of work in Amendment No. 5 will include the following: Preparing Contract Documents for the purchase and installation of grinder pumps on the individual lots, and the connection of the grinder pumps to the low-pressure sewer system, Assisting the City in advertising and awarding the project, d Providing General Construction Representation for the Installation Construction project. The General Construction Representation includes making at least 3 7'.:4 M_'dFAVIFW CO3UAT visits encompassing 6 hours of field representation for each of the SUITE 200 approximately FORT NORTH,TEXAS! $71 10 PI.IONE 812.$46.1700 OFFICIAL 111COID MFTRO 917-S89.222t, t� lie"' PAX r+TtRCO 817.581)nn72 F:lprojec s�318�28001ProjectvlgmtlContracts\01d Amend 5,Now no 6\Rafalko Ltr AmendSProp4.

The field representation will include assisting the City and resident in selecting an acceptable location for the grinder pump station, route of the discharge line,observing the progress and quality of work and assisting the City and contractor in resolving resident issues. A fee table based upon hourly work is attached. The total fee for the above scope is $115,549, of which approximately$71,750 is an allowance for the field representation for the installation of individual grinder pumps. To meet the M/WBE requirements of the original contract, we propose to use Multatech Engineering, Inc.to provide 450 hours of the total 600 hours of the field representation. A proposal letter from Multatech is attached for this work. Multatech's fee would be a not-to- exceed fee of$50,000. 111, Additional Work Performed When the above-referenced contract for the design of the Lake Worth South Shore Low- Pressure Sewer System was originally developed,the Opinion of Probable Construction Cost for the project was $1,459,730. This cost was based on a length of 28,100 linear feet of sewer, which included 1,400 linear feet of gravity sewer and 26,700 linear feet of small diameter low-pressure sewer. With the final route selected, we now have a revised total amount of pipeline on the project. The total amount of sewer line included in the project is 38,400 linear feet, which is an increase of 10,700 linear feet of total pipeline length over the original amount in the contract. Also, the City requested that the gravity line portion be extended as far as possible east and west of the Castle Circle Lift Station. Therefore,the project now includes 10,700 linear feet of gravity sewer and 27,700 linear feet of small diameter,low-pressure sewer. The revised Opinion of Probable Construction Cost is $2,600,000 for the total project. Changing the collection system from a low pressure system,as originally proposed,to a gravity system as requested by the City, resulted in a greater design effort and an increase in the number of drafting hours as plan and profiles sheets are necessary. The set of construction plans currently includes 31 drawings showing the pipeline length, 12 plan and profile drawings for gravity sewer lines and 19 plan drawings for the low-pressure sewer system. The average length of pipeline designed per sheet is 1,200 linear feet. If the set of drawings matched the length in the original opinion of cost, the number of sheets would have been 23, with only 2 plan and profile sheets. Overall, 8 plan view drawings have been added to the design set to show the additional 10,700 linear feet of pipeline length. Also, there are 10 drawings modified to be plan and profile sheets.

City of Fort Worth, Texas Mayor and Council Communication COUNCIL ACTION: Approved on 11/2/2004 DATE: Tuesday, November 02, 2004 LOG NAME: 60LAKEWORTH5 REFERENCE NO.: **C-20377 SUBJECT: Amendment No. 5 to City Secretary Contract No. 27615 with Alan Plummer Associates, Inc. for the Design of the Lake Worth South Sewer System RECOMMENDATION: It is recommended that the City Council authorize the City Manager to execute Amendment No. 5 to City Secretary Contract No. 27615 with Alan Plummer Associates, Inc. for the Design of the Lake Worth South Sewer System in the amount of$154,549, increasing the total contract amount to $1,173,918.78. DISCUSSION: On March 26, 2002 (M&C C-19022), the City Council authorized the execution of an engineering agreement with Alan Plummer Associates, Inc. in the amount of$958,152 for the design of a wastewater diversion from Eagle Mountain Lake drainage basin to the Big Fossil Creek basin and the design of the Lake Worth South Shore Sewer System. The Water Department, the Legal Department and the Department of Engineering conducted a series of meetings with the South Lake Shore Neighborhood Association and the Lake Worth Civic Club to discuss the Lake Worth Land Sales Program and the installation of water and sewer utilities to serve existing development at Lake Worth. The original scope of the low pressure system included only a small diameter force main in the right-of-way and required customers to install the necessary private improvements at their own cost with their own contractors. The community expressed concerned that an average homeowner would not posses the expertise to oversee installation and properly maintain the individual grinder pumps. Water Department staff conducted a national survey to determine how other cities with similar systems delineate the responsibility and found that in most cases the utility owns and maintains the grinder pumps and the low-pressure sewer mains for an additional fee added to each customer's utility bill. The customer also typically pays for the electricity necessary to operate the grinder pump, about $3 per month. City staff is evaluating the possibility of a new wastewater rate class for the grinder pump customers and will present this matter separately at a later date. As a result of the meetings, the City agreed to maximize the length of gravity sewer to serve the south shore area (thereby minimizing the number of lots that would require grinder pumps) and to install and maintain the grinder pumps necessary for the operation of the low-pressure sewer system. Amendment No. 5 includes additional design services to increase the length of gravity sewer, increase the overall length of pipeline, prepare specifications for the installation of grinder pumps on individual residential lots and provide general construction representation for the grinder pump installation. This project is located in COUNCIL DISTRICT 7.
