Newell, P.E., City Enginee� SUBJECT: Street Restoration, City Project OS-08, Section No. OS-00508-00-FP SUMMARY RECOMMENDATION: It is recommended by staff that the City Council approve the attached resolution awarding the contract for Street Restoration, City Project OS-08, to Dunn Company, as the lowest, responsible bidder in the amount of$1,594,407.55, and that the Mayor be authorized to execute the contract and the City Clerk to attest. BACKGROUND: The Engineering Division inspects and rates approximately 1/3 of the City's streets on a yearly basis. The results of these inspections are input into a computer database which is used to project the future condition of the streets based on their current condition, surface type (i.e. brick, concrete, asphalt, etc.), average daily traffic, and traffic type (i.e. trucks, cars, etc.). This data is then paired with available funding and is used as a basis to aid City Engineering in the preparation of the City's yearly street improvement program. Staff then determines which streets need to have the surface restored or be totally reconstructed. The Street Restoration Project generally involves the placement of a 1 to 2 inch hot mix asphalt surface course on an existing paved surface. A portion of the existing pavement is often removed by cold milling to reduce the impact of the overlay on existing curbs and driveways. If additional structural capacity is desired in the pavement, no milling may take place prior to the overlay. The two main purposes of the Street Restoration Project are (1) to increase the useful life of a pavement in advance of its deteriorating to a condition that would require its complete reconstruction and (2) to improve the street's ride ability. This year's program includes approximately 8 centerline miles of streets in the City. A listing of the streets in this year's project is attached. The project specifications were prepared by the Engineering Division and approved by the Illinois Department of Transportation(IDOT) for the use of Motor Fuel Tax funds. The project was advertised on May 5, 2005 and May 12, 2005 and bids were opened on May 20, 2005. The results of the letting are as follows (bid tabulation attached):
