63. BID AND AWARD FOR ASPHALT RUBBER OVERLAY 2010 PROJECT (ARRA) Approve the solicitation of bids for the Maricopa County Department of Transportation's Asphalt-Rubber Overlay 2010 Project (ARRA), Pavement Preservation (PAVE) Project Number T322. Award the contract to the lowest responsive responsible bidder, provided that the lowest responsive responsible bidder does not exceed the Engineer’s estimate by more than ten percent. This project consists of overlaying the existing road surfaces with 1-1/2” Asphalt-Rubber Concrete Pavement. An Asphalt-Rubber Overlay will prolong the life span of a road 15 to 20 years, increase the structural strength of the road to accommodate the higher traffic counts predicted for the near future, and will reduce noise emanating from the traffic on the road. The project consists of approximately 123 lane miles of various arterial roads (1,013,034 square yards), detailed in the included ROAD LISTS. Supervisory District No. 4 (C-91-10-068-5-00)

47. CONTRACT WITH M.R. TANNER FOR ASPHALT RUBBER OVERLAY PROJECT Authorize the Maricopa Department of Transportation to award the contract for the Asphalt-Rubber Overlay 2010 Project (ARRA) to M.R. Tanner, the lowest, responsive, responsible bidder for the project. M.R. Tanner’s bid of $7,833,000 exceeded the Engineer’s estimate by more than 10% so Board approval is being requested to allow MCDOT to award the contract to this vendor. Funding for the project is available in the Public Works (910) Transportation Capital Projects Fund (234) Pavement Preservation (PAVE) Project Number T322. On November 18, 2009, the Board approved Agenda Item C-91-10-068-5-00 for the solicitation of bids for the Asphalt-Rubber Overlay 2010 (ARRA) Project. The Board also approved the award of the contract to the lowest, responsive, respon sible bidder provided that the lowest, responsive, responsible bidder does not exceed the Engineer’s estimate by more than 10%. The lowest bid for the Asphalt-Rubber Overlay 2010 Project (ARRA) came in at 17 percent higher than the Engineer’s estimate of $6,700,499.55. The cost of asphalt-rubber climbed from approximately $55 per ton in December to $70 per ton. This increase was unexpected in so short a time period. This increase in costs is not considered unreasonable given the fact that the seven companies which bid on this project were all within nine percent from lowest bidder to the highest bidder.
