Money for this purpose is appropriated from: Acct. No. 810-701 - Water Utility - Const. in Progress. SUBMITTED BY . _.Pr C y'EP, � - 28 - . � REs. 90-150 � HOWAFaD NEEDL�S 7/aMMEN &.BERGENDOFF ARCHITECTS ENGINL=EqS PLANNERS SCOPE OF SERVICES , In response to the City of Oshkosh request for a proposal for the analysis of improvements to the water distribution system, we are pleased to respond with the following information: � The Firm , Howard Needles Tammen & Bergendoff's qualifications for professional engineering services are extensive. The Wisconsin office was established in 1956, and is locally managed to serve our clients° individualized and specific project needs. Our clients benefit from this on-site personalized service, , and also from the bnoad range of experience and highly speciaiized skilis of the firm's totafl � organization. The Wisconsin office has a total staff of 190, with capabilities in planning, design and construction of Iwater works projects. The staff specialists include civil, environmental, mechanical, electrical, structural, and transportation engineering and architecture. The firm has effectively pioneered the use of multi-disciplined design teams to solve the needs of both large and small projects, 1 Biographical data on the staff proposed for the analysis of the water distriburion system are contained in the Personnel Section of this proposal. That section also contains biographical data on additional � staff inembers available for any subsequent design work that could follow the water system analysis. 1fie firm has extensive experience in the planning and design of water supply and water and � wastewater treatment systems. More than 800 water and wastewater projects, valued at about $2.5 billion, were completed over the last 40 years. Of these, over 200 were waterworks projects. The Experience section of this proposal lists some representative projects involving water pumping stations 1 and storage tanks. Other broader-based experience is documented in the enclosed brochures, HNTB has extensive computer capabilities and would utilize the appropriate computer systems for � undertaking the analytical analyses proposed. Analvsis of Water Service in the Southwest Area � The expansion of the City of Oshkosh to the south and west has strained the abilit of the water Y distribution system to reach out to those extended areas. The higher elevations in that region and high I water demands of some industries in the Southwest Industrial Park, has also caused a drop in water � pnessures at peak usage periods. The potential for reduced water pressures is becoming a concern to the City, � In response to this concem for maintaining adequate water pressure in the southwest growth area, and an paracular the Southwest Industrial Park, HNTB proposes to: l1. Perform a computer analytical analysis of the water distribution piping system in the south and west regiono � -� - 28a - � , ` Res. 90-150 I NOWARD NEEDLES TAMMEN & BERGENDOFF � ARCNITECTS ENGINEERS PLANNERS _� SCOPE OF SERVICES (Contfnued) ' 2.

Develop a capital cost estimate for the construction of the entire booster pressure zone water system and interconnecting service with the exisdng distribution system. lThis analysis will be undertaken in two phases: a) The analytical data will be developed on the basis of data available, and will be evaluated to � determine whether or not there is a need for a new booster pressure zone, as outlined under 1 and 2 above. The results of this evaluation will be reviewed with the City before undertaking any �dditional work. . � b) If it is determined that a new water booster pressure zone is needed, and when directed by the City, complete the analysis as oudined under 3 through 6 above, � Analysis of an Elevated Tank Location North of the Citv � The City of Oshkosh anticipated its long term water needs approximately 20 years ago, and selected a site for an elevated tank in the north growth area. Since water service at that time was adequately � provided to that area without the tank, its construcdon was postponed. The City is now responding to potential demands for rapid expansion to the north and is concemed about the adequacy of water service in this area. . � In response to this concem for providing adequate water service to the growth area north of the City, HNTB proposes to; � 1. Perform a computer analytical analysis of the water distribution piping system in this north region, � 2. Evaluate the City's projected growth plan and corresponding water system needs north of Nevada Avenuee � 3. Develop a conceptual water system plan for this area. � � - 28b - � REs. 90-150 � � �� = HOWARD NEEDLES TAMMEN & BERGENDOFF AqCHITECTS ENC3INEERS PLANNER5 � y SCOPE OF SERVICES (Continued) ( 4.
