TO:              David L. Corliss

FROM:          Steven M. Lashley, P.E.

                   Project Engineer – Infrastructure Management

DATE:           February 11, 2010

RE:               Project No. PW1005 – 2010 Overlay Program Phase 1– City Bid No. B1007

                   February 16, 2010 Consent Agenda Item – Set Bid Date of March 2, 2010

Please include the following item on the City Commission consent agenda for consideration at the February 16, 2010 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 December 1, 2009.  Of the various program projects, the 2010 Crack Seal Program and 2010 Microsurfacing Program were awarded on February 9, 2010 with anticipated project start dates in the Spring, 2010 Overlay Program Phase 2, and the KLINK Overlay of E 23^rd St from Haskell Ave to east City Limits are also planned for this construction season as presented at the December 1, 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 2010 Pavement Maintenance Program for overlay to be paid from the general fund and sales tax reserve.  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 March 2, 2010 for the 2010 Overlay Program Phase 1 - Project No. PW1005.
