City of Centerville 2009 Street and Utility Improvements Page 2 6/77/08 Preliminary Survey This work was completed under previous authorizations. If additional work, not directly related to the streets in the current scope is added to the project, additional survey information will need to be collected. Structure Assessment Sanitary sewer televising reports have been reviewed and used to assess repair needs for the pipe under streets in the project area. The TV reports do not, however, give an adequate condition assessment of the manholes. This work involves inspecting each manhole and documenting its condition, including any problems with: inverts, benches, doghouses, barrel section joints, steps, rings and castings. This work will be done from the street surface and will not involve entering the structure. The information gathered can be cataloged and any needed repairs included in the scope of work. The same type of assessment should be completed for the storm sewer structures. Based on the current project scope, there are 72 sanitary manholes, 57 storm sewer manholes/catch basins and 51 flared ends or weir structures to be inspected. Design {Plans and Specifications} & Bidding This work includes the detailed design of the project documents including: plans, specifications, a bid form and other related documents. To clarify exactly what the scope of this project is, we have attached several figures outlining tire project as it is defined at the time-of this proposal. Should the scope change, the proposed fees contained in this letter will need to be modified. The figures outline street improvements of varying levels (B thru E) as shown on the typical sections. Also noted in the legend are those areas which will have water main and/or water services installed. Still other areas already have water services, but will be offered the installation of the service between the curb stop and home. The work to add this option to the project is not part of this scope, because at the time of this letter, the extent of that work is not known. Not shown on the figures, but part of the design scope are miscellaneous sanitary and storm sewer improvements, required infiltration features, and other work directly associated with the streets in the current scope. These improvements were further outlined in the Feasibility Study. Several trail segments are also shown on the attached figures and are included in those items to be designed under this scope of work. Improvements not directly related to the streets being constructed such as back yard drainage problems or regional storm water work are not part of this scope. Upon completion of the contract documents, we will assist the City in obtaining bids through the public bidding process. We will then tabulate the bids received and prepare a bid results letter. Easements Until design of the project nears completion, the number and size of easements necessary will be difficult to predict. The easement process is further broken down into a few components: sketch and description,
