NOW, THERFORE, BE IT ENACTED BY THE CITY COUNCIL OF THE CITY OF JEFFERSON, MISSOURI AS FOLLOWS: Section 1. The Mayor is hereby authorized to execute a change order with Donohue and Associates for the forcemain replacement improvements for the Cole Junction Pump Station. Section 2.

Passed: ll�t�, -v 65;;V21 Approved:2'"� - - Pjersiding Officers' Mayor ATTEST: APPROVED AS TO FORM: IV V— City Clerk City Counselor P;FviscC) r0hBiTA SCOPE AND FEE COLE JUNCTION PUMP STATION AND FORCE MAIN The following is our understanding of the project as defined in the Technical Memo issued on October 15, 2010. The project includes the replacement of the Cole.function Pump Station to pump a firm capacity of 14,000 gpm or provide a new Pump Station and storage system to pump directly to the wastewater treatment plant. The project also includes the design of a single or dual force main system conveying the Pumped wastewater north under the Missouri River and east to the treatment plant, a piping system of approximately 23,000 linear feet. 'file estimate for the project is $4,800,000 for the pump station and/or a new pump station and storage system. The estimate for the force main is $9,000,000 for a single system or$10,000,000 for a dual force main system. Fees are based on the$4,800,000 for a pump station system regardless if just a pump station or a smaller pump station with storage. The fees for the force main will be based on $9,000,000 regardless if a single or dual force main is designed. Pre-Design Report and Analysis Although a general route has been selected a more defined route needs to be analyzed to determine physical obstacles as well as wetlands, property easements, street and highway crossings and Utility/railroad easements. The route will also be analyzed for constructability to insure the lowest possible construction cost. An analysis will be performed on the pump station system to determine what is more cost-effective, a pump station to pump all flow or a pump station with storage. The selection of this system will determine the size of the force main. A transient analysis of the proposed pump station and force main will be performed to define any restrictions on piping material, location of pressure relief/vacuum relief,appurtenances to prevent hydraulic surge at either the pump station or in the force main. A more detailed capital and O&M cost will be performed. Donohue along with Central Missouri Professional Services, Inc. (CMPS)will perform the study, with CMPS assisting in the route selection. The estimated engineering cost for this analysis is shown on the attached spreadsheet as I A for Donohue and I B for CMPS,and includes costs already incurred. Topographic Survey Surveying at the pump station site and force main route will be performed by CMPS. The fee for surveying is shown in item 2 on the attached spreadsheet. Survey also includes a river crossing survey performed by a sub-consultant for CMPS. Geological Survey Borings will be performed by Engineering Surveys and Services(ESS). The fee for the borings at the pump station site and along the force main route is shown in item 3 of the attached spreadsheet. Permitting Permitting will be needed from the COE, MDOT,and Union Pacific. This task will be performed by Donohue and CMPS. The fee for Donohue and CMPS are shown in 4A and 4B respectively. Easements An estimate of 15 parcels will need easements. This task will be performed by CMPS and is included in item 5. Design Donohue will perform the design of the pump station system and force main system. Design includes review and quality control of sub-consultants work and coordination with either respective design team. Also included are meeting with the City Staff to discuss the design at a kick-off meeting and the 30%and 90% design completion levels to discuss the project details and provide an updated cost opinion. Fee includes particular emphasis on erosion control design. Design also includes a QA/QC of the entire project. Bid documents will be prepared either as one package or separate pump station and fare main documents. The proposed fee for design is shown in item G. Expenses Expenses include reproduction costs for documents and mileage from St. Louis to Jefferson City and are shown in Item 7. Special Investigations During the course of the design and/or right-of-way acquisition phase, certain unforseen investigations may be required. Examples may include geotechnical investigations, geotechnical/hydrological investigations for contaminated soil and/or environmental testing, historical investigations, various record searches, grave sites and/or other investigation or analysis work. The work shall be initiated only with the approval of the City and shall be billed to the City at an Hourly Cost. COLE JUNCTION PUMP STATION AND FORCE MAIN IMPROVEMENTS ITEM NO.
