Exhibit A-3 <br /> AECOM 312 938 0300 tel <br /> 303 East Wacker Drive 312 373 6800 fax <br /> Suite 1400 <br /> Chicago,IL 60601 <br /> www.aecom.com <br /> agreements will be the responsibility of the General Contractor and is not included in <br /> this scope of work. <br /> 3. Cleanouts <br /> a. Repair broken, missing,and/or leaking cleanout covers <br /> b. Any home without a cleanout will receive a new one <br /> 4. Rehabilitation of approximately 70 manholes. <br /> a. Rehabilitation options may include spray sealing, tuckpointing, realignment, <br /> replacement,frame adjustments, internal seals,and external seals. <br /> b. Rehabilitation of flat top manholes will also need additional evaluation, since <br /> replacing flat top manholes with cones, in the City's experience, has been expensive <br /> and sometimes unsuccessful. <br /> 5. Point repairs <br /> 6. Disconnections of existing downspouts <br /> In a previous study, AECOM reviewed closed circuit television (CCN) data of this portion of the <br /> City's existing sewer collection system. Furthermore, since the selected General Contractor will also <br /> be performing their own CCN analysis, no CCTV review will be performed under this scope of work. <br /> For City owned streets, the design will include only a general maintenance of traffic (MOT) plan for <br /> maintaining two-way traffic, etc. Since this is mostly a residential area with light traffic, the design will <br /> not include detailed MOT design for each block and/or area that requires construction. For the <br /> rehabilitation work that will be required on Oakland Avenue (Illinois Route 48), detailed MOT design <br /> will be provided, as this will be required for the Illinois Department of Transportation (IDOT) permit <br /> (see Task 3).Applicable IDOT MOT standards will be followed. <br /> An Engineer's Opinion of Probable Construction Cost will be prepared and presented to the City and <br /> include a 20 percent construction contingency(50% bid documents)and no construction contingency <br /> for the 95%and 100%bidding documents. <br /> Also included in this task is assisting the City in developing a service charge/fee for those residents <br /> that choose not to be included in the project. This will include estimating the cost of each lateral, as <br /> well as estimating the additional 1/1 that may leak into the system (and associated costs)as a result of <br /> the resident's decision not to be included in the project. <br /> Each set of design documents will undergo AECOM's internal QA/QC procedures. At the conclusion <br /> of our QA/QC process, internal comments will be incorporated and identified issues will be <br /> addressed. Deliverables will then be issued to the City for review and comment. AECOM will meet <br /> with City personnel to discuss comments. AECOM will capture client comments into document <br /> review forms and track the status of response/action in order to satisfactorily address all comments. <br /> Deliverables: <br /> • 50%bid documents <br /> • 50%Engineer's Opinion of Probable Construction Cost <br /> • 50%Review Meeting Minutes <br /> • 95%bid documents <br /> • 95%Engineer's Opinion of Probable Construction Cost <br /> • 95%Review Meeting Minutes <br /> • 100%bid documents <br /> • 100% Engineer's Opinion of Probable Construction Cost <br /> 3 <br />
