RE:               Project No. PW0907 – 2009 Overlay Program Phase 1– City Bid No. B09022

                   March 24, 2009 Consent Agenda Item – Set Bid Date of April 7, 2009

Please include the following item on the City Commission consent agenda for consideration at the March 24, 2009 meeting:

Project Description.  This milling and overlay project includes a number of City residential streets.  The street mill and overlay sections to be worked on are determined to be in generally fair to poor condition and have deteriorated beyond the point at which cost-effective preventative maintenance techniques can be performed.  This type of minor rehabilitation work is utilized when some structural deficiencies exist along with other signs of progressed deterioration that lead to poor drainage and diminished ride quality.  An effective milling and overlay program will reestablish desired drainage, structural, and ridability characteristics to a street and reduces other long-term maintenance and rehabilitation costs.

Project History.  The city’s annual pavement maintenance program was reviewed and approved by City Commission on January 27, 2009.  Of the various program projects, the 2009 Crack Sealing Program was bid on March 3, 2009, the 2009 Curb and Gutter Replacement Program will bid on March 24, 2009, W 9^th St Tennessee to Iowa Sales Tax Program Rehabilitation Project, KLINK Overlay of W 23^rd St from Iowa to Kentucky Ct, 2009 Overlay Program Phases 2 and 3, and the 2009 Microsurfacing Program are also planned for this construction season as presented at the January 27, 2009 City Commission Meeting.

Project Details.  The project includes milling existing pavement, patching deteriorated areas, and placing a 2-inch overlay pavement to restore structural capacity, skid resistance, proper drainage, and ride quality to the pavement on existing City streets.

Project Funding.  The pavement maintenance program is funded from several sources including the general fund, gas tax funds, sales tax and sales tax reserve, and capital improvement reserve accounts.  This contract was included in the 2009 Street Maintenance Program for Overlay budgeted at $400,000.00 to be paid from the general fund.  The contract includes an asphalt index which may require change order(s) based on the increases/decreases in asphalt oil pricing.

Action Request.  Set Bid Date of April 7, 2009 for the 2009 Overlay Program Phase 1 - Project No. PW0907.
